电弧炉熔炼高锰钢经常采用返回法工艺,即:装料送电熔化后,初还原扒去部分炉渣,再造新渣;加还原剂进行扩散脱氧,渣白后取样分析并根据分析结果调整成分;当温度合适、氧化铁和氧化锰之和小于1.5%时,即可插铝出钢。这种熔炼工艺的电耗高达850kW·h/t钢水。为此,我们运用网络图原理对返回法工艺的各个环节的时间及先后进行了合理安排,从而缩短了冶炼时间,使电耗降低到670kW·h/t钢水。
EAF smelting high-manganese steel often use the return process, namely: charging power transmission melts, the initial reduction of the grilled to some slag, and then create a new residue; plus reducing agent for diffusion deoxidation, slag after sampling analysis and adjust the composition according to the results ; When the temperature is right, the sum of iron oxide and manganese oxide is less than 1.5%, you can insert aluminum tapping. This smelting process consumes up to 850 kWh / t of molten steel. To this end, we use the network diagram principle of the return process of all aspects of the time and precedence reasonable arrangements, thereby shortening the smelting time, the power consumption reduced to 670kW · h / t molten steel.
