Source title:Ogneupory Abbreviated source title:Ogneupory Issue:3 Issue date:Mar Publication year:1991 Pages:24-27 Language:Russian CODEN:500064 Document type:Journal article (JA) Abstract:Comparative testing of standard and experimental products in gas-oxygen refining converter (GOR) of Dneprospetsstal' plant was carried out to check the possibility to use the PSPC type products in the lining of GOR, expensive and deficient molten fused magnesia chromite being replaced by sintered one. Performances of the campaigns compared were practically identical. In the process of commercial operation no specificities in the character and wear intensity of the products compared were pointed out. Both types of the products are subjected to erosion-corrosion fracture by intensively moving slag-metallic bath. Replacement of molten fused magnesia chromite by sintered one does not decrease wear resistance of separate elements of the GOR lining beyond the slag belt, which can increase economic indices of the process at the expense of refractory cost reduction. 6、Title:Reaction model for carbon, manganese, and oxygen in bottom blowing with mixed gas in final stage of steel refining in converter Authors:Kato, Yoshiei (1); Okuda, Haruji (2) Author affiliation:(1) Patent and Tech.

A reaction model which combines the stoichiometric and equilibrium relationships among carbon, manganese, and oxygen and their mass transfer rates was made for decarburization as a gas-metal reaction and for manganese and iron oxidation as slag-metal reactions. It was assumed that 1) addition of inert gas through submerged tuyeres contributes to bath stirring as well as to a decrease in CO pressure, and 2) all rate determining steps in the gas-metal and slag-metal reactions are the mass transfer of carbon, manganese, or oxygen in the molten steel. Fitting the parameters under a 1/1 oxygen-nitrogen flow rate ratio, the calculated metallurgical properties in ordinary blowing (bottom blowing with pure oxygen) agreed well with the experimental results. Calculations for certain operating factors showed that the decarburization rate increases and the oxidation rates of manganese and iron decrease as the bath temperature increases and the ratio of oxygen to inert gas decreases. The contribution ratio of the gas-metal reaction relative to the slag-metal reaction in bottom blowing with mixed gas is 6 to 9 times larger than that in top blowing with mixed gas. 7、Title:Gas-oxygen refining of steel Source title:Stal' Abbreviated source title:Stal Issue:4 Issue date:2003 Publication year:2003 Pages:34-35 Language:Russian ISSN:0038920X CODEN:STALAQ Document type:Journal article (JA) Publisher:Intermet Inzhiniring Abstract:In order to produce high-quality steels, various metallurgical units are used. It has been shown that efficient method of smelting the steel is gas-oxygen refining. Combination of electric arc furnace and basic oxygen converters is applied in this case. Special gas-oxygen refining converter has been developed. Smelted steel is utilized for casting the ingots applied in processes of rolling and forging. High-quality corrosion-resistance steels are produced with the use of this technology. Low-carbon steels of 02Kh18N11, 03Kh17N13M2T, and other grades are produced which are characterized by high properties. 8、Title:Optimization of gas-oxygen refining of stainless steels Authors:Shul'ga, V.O.

Regularities in variation of parameters of the process have been determined.
