    Summary: By decreasing sulphur activity coefficient in metal and bystabilizing of carbide structure, manganese influences favourablythe pig iron quality. By continuous adding of manganese ore tothe blast furnace charge, mathemetical dependence of manganeseand sulphur concentracion in metal in the entire interval ofconcentracion changes in the observed metals was noticed.Selective analysis of the dependence of high and low manganeseconcentrations in metal and sulphur shows that stronger manganeseeffect on sulphur concentration decrease is evident at theincreased manganese concentration in metal.

    Summary: The external and internal quality of seamless tubes in the SisakSteelwork is unsatisfying. The tubes are manufactured fromingots, continuous cast blooms and rooled billets. The defectscoming from raw materials (semis) are more frequent on tubesrolled from ingots, due to the poor surface and in adequate topform. The major share of surface defects originates frominclusions caused mostly by worse pit refractories. A deepshrinkage cavity is caused by casting in big-and-dawn moldswithout hot tops. The surface of tubes from continuous castblooms is not much better because of the large frequency ofsurface inclusions and internal cracks.

    Summary: The semis for seamless tubes at the Sisak Steelworks will befuther produced in the own steel plant, which has to be soonrestructurized. Instead of the present three furnaces, two OH andone little EAF, only one modern EAF will operate which would havesuch capacity in order to use the existing plant and equipmentfor transport and casting. The steel will be continuous cast andtherefore one of the existing machines will be adapted forcasting blooms and the other for billets. More processes laddlemetallurgy will be used.

    Summary: The paper presents the results of the analysis of the influenceof a pusher-type furnace productivity increase on the decrease ofa specific heat energy consumption. As it has been analyticallyfound and verified in operating practice, if the furnaceproductivity increases from 37 to 61 t/h, the specific heatenergy consumption decreases for about 18 %. By increasing thefrequency of isolation maintenance of a pusher-type furnace, aspecific heat energy consumption would decrease, which is possible to acheave by a better month and week planning ofrolling.

The greatest portion in thecosts of the steel production in the electric arc furnaces isenergy-and electrodes consumption. The energy portion in thesteel production by the converter procedure is insignificant. Theproduction cost in the converters is considerable lower relatedto the production cost in the electric furnace. Comparing thesteel price of electric-and converter procedure, the charge costsare found to be the most important factores.

    Summary: The deformation anomalies of higher orders at plastometric tests are studied on easily deformable lead alloys-models of different rheological complexity by original testing methods. It is ascertained that the development of deformation anomalies depends upon the degree of rheological complexity of the material. Simple strain anomalies are due to the inadequate conditions of contact friction, while those of the highere orders results mainly from microrelief of the sample butts. Recommendations for the obtention of homogeneity of deformation at plastometric tests are given. The testsshow that the deformation of rheologically complex metals develops according to laws basically different of the contemporary notions of the mechanics of plastics deformation.

     Summary: In determining the oscillation parameters, the relation of the mould oscillation speed and the casting speed must be considered. A suitable negative strip ratio must be assured. The mould speed depends on the product of the amplitude and the frequency. Experience showed that it is more suitable to cast at low amplitudes and high frequencies. The demand for a low amplitude arises from the requirement that the displacement of the mould during the negative strip time must be smaller than the thickness of the slag layer on the steel meniscus in the mould. In this paper, the bases for optimization on the oscillation parameters are given, the relation of this parameters to the behaviour of casting powders, and some results obtained in Steelworks Sisak are presented.

The results obtained revealed close connection of SSC with mechanical properties and microstructure:resistance to corrosion is decreased while yield strength and hardness are increased by changing beat treatment conditions. Differences in SSC-resistance are consequence of microstructural parameters like number of phases, grain size, morphological characteristics and distribution of carbide particles.

     Summary: Heat treated specimens of Single crystal nickel base superalloy were submitted to tension creep at the temperature of 900řC. The deformation process was investigated at different states of creep. In the matrix hardened by bimodal precipitates the development of dislocation structure and precipitates morphology changes were studied by means of TEM on longitudinal sections of creep deformed samples close to fracture surfaces. The observation of fracture surfaces shows that fracture induced by creep damage starts from incipient casting pores of cracks initiated in carbide precipitates.

     Summary: The effect of different initial microstructures defined by various precipitates morphology was investigated at the creep/fatique conditions by 900řC and 500 MPa. The wave form of stress as a function of time for cyclic loading was of trapezoidal shape with a hold time 10 seconds at the upper stress level. TEM was employed to examine the deformation process in a strengthened matrix in dependence of precipitate morphology. The fracture lifetime and cycles up to fracture were the criteria for the evaluate the additional cyclic component effect on the course of deformation.

     Summary: Environment sensitive cracking of high strength low alloyed (HSLA) steels usually occurs in deep sour wells. Hydrogen sulfide dissolved in water and oil phase has been proved to be the principal species responsible for sulfide stress corrosion cracking (SSCC). In this work, resistance to SSCC of an experimental low alloyed Mn-Mo steel was increased by properly chosen heat treatment conditions. Tensocorrosion tests and microstructural investigations by x-ray diffraction revealed that residual stresses are reliable indicator of SSCC-susceptibility.
     Keywords: HSLA steel, residual stress, sulfide stress corrosion cracking.

     Summary: The friction force at continuous castings of steel represents thedifference between the force acting at the mould oscillationduring casting and in the idle motion. For the measurement ofthis force more methods are used: extension band, load cell andpower of the oscillator motor. In this work the friction forcewas determined from the difference of the acceleration measuredby a vibrometer: at the idle oscillation, with load of known massand during casting. The method does not require the insertion ofsensors in the parts of the oscillation system. The acchievedvalues of friction force depend on the oscillation parameter.

All specimens fractured after charging revealedbrittleness, with less ductibility - loss in steel with moresulfur. The same steel also had better resistivity to sulfidestress corrosion cracking, what was ascribed to more orderedmicrostructure obtained by heat treatment (normalizing). Thehighest resistivity to hydrogen embrittlement has shown the lowsulphur steel after normalizing and tempering.

     Summary: The paper represents the research of the influence of the condition of pickled and thermally treated surface on the quality of operation for temporary protection of seamless steel tubing. It was found that, in the presence of oxidation, a significant amount of oxsidelayers Fe3O4, as the basic phase, and other ferrous oxside Fe2O3 and FeO are formed on the surface of hot-rolled seamless steel tubing. The scanning x-ray analysis of pickled samples in sulfuric acid, in operating conditions, has shown the presence of remaining oxide layers-scale and the occurence of clean metal surface at the same time. With the thermal treatment, the sharee of oxide layers-scale is significantly increased. The protective coat discontinuously covers such a surface. The best results have been obtained with laboratory pickling, thermal treatment, and with the protection of hot-rolledseamless tubing at controlled pickling parameters(bath composition and temperature, pickling time, washing out after pickling) and the atmosphere in the thermal treatment oven. The best results have been obtained by sand blasting of oxside layers-scale(mechanical method).

     Summary: A literary review of the development of open-heart steelproduction has been given in the work with special regard to thepresent achievements in balacing carbon content and melttemperature in the refining process as well as optimal control ofthermal regulation. The work is directed to seeking adequate influence ofdecarbonication, which is calculated by means of flue gasanalysis in the vertical canal of furnace head and otherparameters in open hearth furnaces, upon fuel consumption. It hasbeen shown that melt heating during the refining process withoxygen injection without fuel feeding is impossible in smalleopen-hearth furnaces. The method of carbon content follow-up has been in proved in therefining process by means of flue-gas analysis in the verticalcanal of furnace head. The accuracy of carbon content follow uphas been increased by flue gas analysis in the vertical canal inthe relation to the analysis of flue gas in the common flue. In the concluzion of this work optimal necessary flow mass ofmasut for continuous control of melt heating in the refiningprocess obtained by means of model has been shown depending ondecarbonisation rate and other parameters without continuousmeasurement of melt temperature.

     Summary: This paper presents the possibilities of more rational use ofenergy in order to save fuel, intensity the technological process, improve the economical production indexes and quality ofproducts. Special emphasis is given to the effects that may beachieved by waste gases heat utilization in which field nowadaysthe most significant reserves in the rationalization of energyfuels use exist. In the paper the method is suggested which proposes moresystematic and complex access to the improvement of technical andeconomical characteristics of the heating furnace energyconsumption, since it is impossible to give a unique integraltechnical solution taking in considerstion the specific problemsof each furnace in different environments. For the sake ofoptimization one-dimensional mathematical model of radiationrecuperator and sectional furnace has been developed which hasdetermined their optimal technological, constructional and energyparameters.

     Summary: The meniscus appearances during continuous slabs casting havebeen investigated by metallographic technique and mathematicalanlysis. The mathematical tests have shown that the oscillationmarks could be classified according to the presence or absence ofsmall hook in the subsurface structure. The positive segregationof the soluted elements, especially the phosphorus ones have beentracted at the bottom of the oscillation marks and have beenclassified into two types. The first type has been tracted at theunder surface hooks, whereas the other type of the positivesegregation is found at the bottom of the oscillation marks. Thetransverse cracks occur along the bottom of the oscillationmarks. The surface of the transverse cracks shows interdendriticappearances in the vicinity of the slab surface which means thatthe cracks have started when hot slab broke into the mould. It isshown by the theory of lubrication that due to film geometry ofthe molten powder which is found between the meniscus solidifiedshell and mould wall, considerable pressure gradient is in acondition to deform the meniscus. The pressure gradient in themolten powder is created by reciprocal mould progression inrelation to the slab solidified shell. The surface balance offorces between steel and molten powder is applied for calculatingthe meniscus as a function of the pressure created in the film atdifferent stages of the mould oscillation cycle. This shows thatthe contact point between the meniscus and the mould goes out ofthe phase for 1/2f and has a large amplitude than the moulddisplacement. By heat transfer analysis, the temperaturedistribution is predicted in the infiltrated film between thesolidified slab shell and the mould wall.

     Summary: The use alluminium alloy casting in the past decade has had aphenomenal grown paralleling that of aluminium products ingeneral during the same period. More and more traditionalmaterials are being replaced by improved aluminium castingalloys. Alloying elements, such lead, zinc, tin and sodium which havereletively low melting points usually are added tod melt as puremetal to the aluminium. Other alloying elements regularly addednickel, boron and beryllium. This metals are usually added topure aluminium in the form of rich alloy ingot. Permanent molding and die casting involve higher tooling charge,but unit price is lower particularly for langer runs. Diecasting are extreme, usually involving highest tooling charge andlowest piece price on large quantities. Alloys whose destined to produced "prirubnica" are AlSi12Cu andthis is a light strenght alloy used for other components designedfor severe service conditions. Fluidity is excellent, pressuretinghtness is very good and resistance to hot cracking is good.This alloy has good machinability, polished finishes are good andcorrosion resistance is good.

     Summary: The definition of process parameters making influence to the quality of iron with application of personal computer and program package based on the mathematical statistics method, represents one of the ways for mastering and improvement of the general iron quality. The offected data processing, covering a longer time period, on the investigated aggregate, indicates one unstable technological process based on the unprepared(raw) charge and low blowing temperature parameters. This causes a low utilization of gas reduction capability, higher participation of direct reduction, low production and high coke consumption. The analyses of iron quality and distribution of the particular elements between iron and slag in the suitable reduction atmosphere, point out the importance on maintaining the thermal conditions within the furnace chamber as on important cause of iron composition variation. The evaluation of the parameters influencing the production and iron quality indicates the necessity of: benefication of ore stopping, homogenization of charging materials, increase of temperature and blowing air, proper selection of slag quantity, corrections or changes of current desulphuration method, introduction of accurate and fast quality control during the production process, introduction of information system for the monitoring and planning the iron production. The improvement of average obtained values of influencing parameters within these raw materials and technological conditions of production in Iron Works Vareš will provide the decrease of dry coke consumption by 55 kg/t of iron, increase of production by 12,45% and iron production of considerably higher quality.
