Data about quality of ferroalloys used for electric steelmaking and alloys with special properties controlled by specified nonmetallic inclusions according to GOST 801-78 and ASTM E-45 (method A) are generalized and analyzed. Results of investigation of matrix and proeutectoid phases in the structure of industrial carbonaceous ferrochromium with application of electron microscopy and electron probe microanalysis as the main alloying ferroalloy at roller-bearing steel IIIX15C{cyrillic}-B smelting are presented. © Metallurgical and Mining Industry, 2011.

Regression models of chromium, silicon, manganese and carbon content behavior in metal depending on the amount of added carbonaceous materials,ferrosilicomanganese MnS17, ferromanganese FeMn78, ferrosilicon FeSi65, ferrochromium FeCr800 are obtained as a result of analysis of experimental data for bearing electric steel IIIX 15 and IIIX15CT-B. These models enable to forecast chemical composition of steel in order to save reducing agents and alloying elements. The structural diagram of automated information system of ladle-furnace is designed according to results of investigations. © Metallurgical and Mining Industry, 2010. Source
