Abstract:Aiming at efficient sensible heat recovery of molten steel slag,the BOF-slag treatment interface was studied and the transport process of molten steel slag was optimized by the method such as time series analysis and virtual simulation,the transport path,operation time,on-line operation quantity and interface energy loss of steel slag tank were analyzed,the optimal path of low heat loss transport of molten steel slag was determined,and then efficient transfer of material flow and energy flow between interface can be achieved. Virtual simulation and test results show that it can meet the existing production require of the BOF when running quantity of on-line slag tank was 8 at least,the turnover times of single slag tank was 7.88 times per day,and the turnover efficiency of slag tank is increased by 37.50%. Based on this calculation, the temperature drop in the steel slag transport process was about 209 ℃,the interface energy loss is reduced by 30.4% compared with the initial condition.
