Optimization of the slag-making process in the LF refinery
By implementing a reasonable pre-slagging system and a continuous casting slag recycling system,the LF refining furnace slagging process has been optimized,and a pre-slagging system has been implemented during the outlet of the converter to achieve deep oxidation removal of the steel water,a reducing slag at the top,and improve the speed of forming white slag in the LF furnace,thereby improving the sulfur removal efficiency,promoting the full upward floating of impurities in the steel water,and improving the purity of the steel.The continuous casting slag recycling system for hot liquid refining reduces the consumption of slag materials and energy in the LF refining process,achieves a good under-arc effect for the refining slag,improves the utilization rate of the electrode,reduces electricity consumption,and at the same time reduces noise pollution,smoke and harmful substance emissions dur-ing power supply,low-carbon and environmental protection.After the optimization of the slagging process in the LF refining furnace,a fast and stable white slag formation process is achieved,improving the sulfur removal efficiency,shortening the refining cycle,improving production efficiency,improving the purity of the steel water,and at the same time reducing the aluminum consumption,ash consumption and electricity consumption,achieving an efficient,low-cost and environmentally friendly LF slagging process.
