戚墅堰机车车辆修理工厂翻砂车间在铁道部铁道研究所的直接帮助下,进行碱性化铁炉的生产试验工作,已获得成功,并已应用到生产中。碱性化铁炉可以全部利用废铁、废钢来熔炼出含硫、磷量很低的供制造球墨铸铁用的铁水,不但可以节省下来大量的新生铁,同时也解决了目前低磷生铁缺乏的困难。碱性化铁炉制造了来的球墨铸铁,韧性及动击性都较普通球墨铸铁高。
Qishuyan locomotive and rolling stock repair shop plant directly under the auspices of the Ministry of Railways Institute, the production of alkaline iron furnace test work has been successful and has been applied to the production. Alkaline iron furnaces can all use scrap iron and scrap steel to smelt molten iron with low sulfur content and low phosphorus content for producing ductile iron, which can not only save a large amount of fresh iron, but also solve the problems of the current lack of low phosphorus pig iron difficult. Alkaline iron furnace made of ductile iron, toughness and mobility are higher than ordinary ductile iron.
