With the expansion of ferroalloy production scale and in order to meet the requirements of energy saving, using refining technology in the ferroalloy production is a development direction for the future. As a technology for stainless steel production AOD technology is already very mature, but its ferroalloy production for the research work is still in its infancy. The frequent splashes take place in an AOD furnace in the ferroalloy smelting process. At present, an empirical model to prevent splash is basica...
