REGULATED PREPARATION AND INDUSTRIAL APPLICATION TEST OF SEMI-COKE FOR FERROSILICON SMELTING
The regulated preparation method of semi-coke for ferrosilicon smelting is introduced,and the application of semi-coke produced according to the regulated preparation method in ferrosilicon smelting is investigated,and the feasibility of the regulated preparation method is confirmed through the quality testing of the regulated preparation semi-coke and the tracking and analysis of the smelting indexes of the semi-coke after entering into the ferrosilicon furnace.The test results show that the regulated preparation method by means of selecting raw coal,adjusting the dry distillation process parameters and re-optimizing the reductants can stabilize the semi-coke quality,and effectively reduce the e-lectric power consumption of ferrosilicon smelting.The performance of industrial semi-coke can be predicted by evalua-ting the performance of altogether coal pyrolysis semi-coke,and then altogether coal suitable for the production of ferro-silicon smelting can be optimized.By optimizing the selection of altogether coal and regulating the parameters of the dry distillation process,high performance ferrosilicon semi-coke with stable composition and properties can be produced.
