classification of bof slag by data mining techniques,in the process of converting pig iron into steel, some co-products are generated—among which, basic oxygen furnace (bof) slag is highlighted due to the great amount generated (about 126 kg of bof slag per ton of steel grade). great efforts have been made throughout the years toward finding an application to minimize the environmental impact and to increase sustainability while generating.rongsheng kiln refractory,metallurgical fluorspar for converter steelmaking metallurgical fluorspar is the most commonly used flux for converter steelmaking. it has an obvious effect on lime melting and slag dilution, and the slag is quickened and the amount used is small. fluorspar caf2 has strong corrosiveness after decomposition, which seriously corrodes the furnace.
