Abstract:In view of ironmaking fuel ratio of blast furnace in PingGang, discussed the technical measures of reducing fuel ratio from various aspects of raw materials metallurgical properties, grain composition, burden design, reasonable smelting intensity, slagging regime, multi-circle burden distribution, appropriate for coal powder, smelting low silicon Iron and so on. The study shows that the key technical measures to lowering the fuel rate are improving the quality of coke, further screening and size stabilization, choosing the suitable smelting strength and appropriate MgO slag system, narrowing weighted average angle difference, avoiding excessive center coke charging, choosing coal ratio according to the raw material and fuel conditions and stabilizing silicon content of pig iron
