摘要
本文介绍了留渣-双渣工艺的工艺原理,结合八钢公司40 t产线的工艺条件对留渣-双渣工艺的试验情况做了详细的阐述,通过控制枪位,调整渣料装入等方法,取得终点磷含量0.012%,石灰消耗降低8.14 kg/t,生白云石消耗降低10.17 kg/t,吹损降低0.6%的实际效果。
This paper introduces the process principle of leave slag-double slag, and gives a detailed description of the process test in combination with process conditions of 40T production line. By the means of controlling the lance height and adjusting slag material loading method, etc, the actual effect is acquired with 0.012% of the end phosphorus content, 8.14 kg/t reduction of lime consumption, 10.17kg/t reduction of raw dolomite consumption and 0.6% reduction of blowing loss.
