第一座碱性化铁炉改装成功我国第一座「碱性化铁炉」已在戚墅堰机车车辆修理厂改装成功,并开始生产大量质量良好的球墨铸铁。过去,我国都是用「酸性化铁炉」(又名普通冲天炉)来熔炼球墨铸铁的,它需要大量的低磷的新生铁来作原料,而且有时在质量上不能合乎要求。现在,把原「酸性化铁炉」改装成「碱性化铁炉」,就可全部利用废铁、废钢来熔炼球墨铸铁,把大量新生铁节省下来。特别是「碱性化铁炉」熔炼出来的铁水,如果应用到贝氏炉作为炼钢之 The First Alkaline Furnace Retrofit Success The first “basic iron furnace” in our country was successfully retrofitted at Qishuyan Locomotive and Rolling Stock Works and started to produce a large quantity of ductile iron with good quality. In the past, our country used “acidified iron stove” (aka ordinary cupola) to smelt ductile iron, which requires a large amount of low-phosphorus fresh pig iron as a raw material, and sometimes can not meet the quality requirements. Now, converting the original “acidified iron furnace” into an “alkaline iron furnace” can all utilize ductile iron and scrap to smelt ductile iron and save a large amount of fresh iron. In particular, "Alkaline iron furnace melting out of the hot metal, if applied to the furnace as a steel furnace
