The influence of technological parameters of smelting on the durability of the lining of an arc steel-smelting furnace under the conditions of Ural Steel JSC

The results of the study of the influence of the main technological parameters of steel smelting (composition of charge materials, duration of smelting and furnace downtime, oxidation refining intensity and metal temperature at the outlet) on the lining resistance of a small arch of a steel-smelting arc furnace in the Ural Steel JSC are presented. Recommendations have been developed for optimizing the technological and energetic regimes of steel smelting, which make it possible to prolong the service life of the lining of a small vault and reduce the cost of steel production.

The investigation of the converter slag's phase and mineralogical properties in splashing to improve the lining resistance

The methods to improve the slag splashing operation were regarded in the article. The phase and mineralogical properties were studied for the converter slag's of one of the Europe Iron and Steel Works. The modeling results for the slags with different compositions are given on base of the earlier studies of the physical and chemical properties.Ill.8. Ref. 28. Tab.1.
