鞍钢机械制造公司铸钢厂运用价值工程方法,改进平炉冶炼沸腾钢加锰铁的操作规程新工艺。降低了锰铁的消耗,增加了钢的产量。 过去生产沸腾钢是采用炉前加锰的操作工艺,理论计算锰铁的加入量每吨钢应是4.5公斤,而实际加入的是9.13公斤,锰铁的利用率只有50％,这说明加锰工艺及锰本身存在着较大的剩余功能。经过认真调查研究、VE方案创造,应用罐内加锰铁 Angang Steel Machinery Manufacturing Co., Ltd. uses a value engineering method for the steel plant to improve the operating procedures and procedures for the open-hearth smelting of boiling steel and ferromanganese. Reduces the consumption of ferromanganese and increases the output of steel. In the past, the production of boiling steel was performed by adding manganese before the furnace. The theoretical calculation of the amount of ferromanganese added was 4.5 kg per ton of steel, while the actual addition was 9.13 kg, and the utilization rate of ferromanganese was only 50%, indicating that manganese was added. The process and manganese itself have a large remaining function. After careful investigation and research, VE program creation, application of ferromanganese in tanks
