引言生产低碳钢或其他对碳有严格要求的某些特殊钢时,最好使用含锰80—85％、含碳和硅都不大于1.5％的中碳锰铁。含硅0.20％的这种低硅产品可用于低碳深冲性的钢种。传统的生产中碳锰铁的方法是用硅热法还原锰矿石。联合碳化物公司最新发展的MOR方法,即用吹氧的方法脱除高碳锰铁 INTRODUCTION In the production of mild steel or other special steels with stringent requirements on carbon, it is best to use a medium carbon ferromanganese that contains 80-85% manganese and no more than 1.5% carbon and silicon. This low-silicon product, 0.20% silicon, can be used in low-carbon deep-drawn grades. The traditional method of producing carbon-ferromanganese is to reduce the manganese ore by the silicothermal method. The newly developed MOR method by Union Carbide Corporation is the removal of high-carbon ferromanganese by oxygen blowing
