试用高纯生铁熔制铸态铁素体球铁

Use High-pure Pig Iron for Melting Ductile Iron Castings with Ferritic Structure As-cast

我国炉料市场中很少遇到深冲废钢，以结构钢为主的普通废钢含有一些珠光体稳定元素，以这种废钢为主的炉料，熔制不出铸态铁素体球铁。

There is a few of scraps of deep-drawing steel in China charge market, lot of scraps of constructional steel, that are bearing many trace elements, particularly those that promote a pearlitic matrix structure. Use charge of the scraps mainly for melting ferritic castings as-cast should be not available.
