中碳锰铁是炼钢工业上的重要原料之一,也是电焊条生产不可缺少的原料。由于我国锰矿资源的日益贫化,杂质含量也相对增加,生产过程渣量大(每吨产品有二吨以上的废渣),再加上炉渣不能水淬利用,致使废渣成灾。我厂中碳锰铁年产量虽不 Medium carbon ferromanganese is one of the important raw materials in the steelmaking industry. It is also an indispensable raw material for the production of welding electrodes. Due to the increasingly depletion of manganese resources in our country, the impurity content is also relatively increased. The production process has a large amount of slag (more than two tons of product per ton of product), and slag can not be hardened by water, resulting in the disaster of slag. I plant carbon ferromanganese production, though not
