1熔炼顺序冲天炉前半部分结合订单的情况按灰铁配料熔炼,后半部分按球铁配料熔炼,在灰铁与球铁料相接部分,铁液含碳量高,偏软,所以灰铁料先配厚大件料(含碳量低),后配薄壁件料(含碳量高),使灰铁件与球铁件的相互影响减小。灰铁产品浇注完成后,加隔离焦,开始配球铁料。隔离焦使用优质铸造焦,加入2.5批 1 melting sequence Cupola the first half with the situation of the order by the gray iron ingredients smelting, the second half of the ball according to the ingredients of iron smelting, gray iron and dumb iron material in the connection part of the liquid iron high carbon content, soft, so gray iron Materials first thick material (carbon content is low), with thin-walled material (carbon content is high), so that the interaction between gray iron pieces and ductile iron pieces reduce. Gray iron product pouring is completed, plus isolated coke, iron ball began to match. Isolate coke using high quality coke, add 2.5 batches
