Optimization of Steelmaking Process for 200t Converter

Abstract:

Article Preview

To solve the problems appeared in the initial operation period of 200t BOF such as low heating velocity, high TFe content in final slag, severe lining erosion, etc, optimization of steelmaking process is carried out. Metallurgical effects are greatly improved after optimization: slag-forming time is shortened by 0.9min; oxygen consumption is lowered by 1.5 m3 per ton steel; carbon content of aimed molten iron is increased by 0.031% while oxygen activity of which is decreased by 206ppm. TFe content of BOF slag is reduced by 0.84% on average.
