提高钢锭的利用率是降低锻件成本的重要途径之一。
I had saw one of the conventional steelworks: huge blast furnace, converter, steel ingot, mile of railway track.我参观过传统的炼钢厂:巨大的高炉、转炉、钢锭,长达几英里的铁轨。
This paper has theoretically studied the effect of blowing Ar into molds on improving killed steel ingot quality.本文从理论上分析了采用锭模吹氩对提高镇静钢质量的作用。
