高锰铸钢是我厂大量生产的主要产品,自开始生产以来,一直是在碱性电弧炉中采用不氧化法熔炼,根据苏联资料及一般文献介绍,高锰钢旧料(包括浇冒口、废品及旧零件)在炉料中的比例不得超过40~47%,而我厂的实际情况是浇冒口重量大(占浇铸钢液重量的50%左右),而高锰钢的旧零件来源也很充足,如对高锰钢旧料不能充分使用,便造成旧料的积累。另一方面增加了炉料中所用的优质优低碳废钢和锰铁消耗量,不仅提高了原料费用,而且经常造成原料的供不应求。因此,增加炉料中高锰钢旧料的用量,可以解决原料利用上的不合
High manganese steel is the main product manufactured by our factory in mass production. Since it started production, it has been used in alkaline arc furnace without smelting. According to the information of the Soviet Union and the general literature, , Waste and old parts) in the charge of the proportion of not more than 40 to 47%, while the actual situation in our plant is pouring riser weight (accounting for about 50% of the weight of molten steel), and the source of the old parts of high manganese steel Is also very adequate, such as high manganese steel can not be fully used, will result in the accumulation of used materials. On the other hand, it increases the consumption of high-quality low-carbon scrap and ferromanganese used in charge, which not only increases the cost of raw materials but also often leads to the shortage of raw materials. Therefore, increasing the amount of high-manganese steel charge in the charge, you can solve the use of raw materials on the substandard
