为了解决炼钢电弧炉采用高功率和吹氧强化冶炼操作后炉衬寿命降低的问题,我们在1.5T电弧炉上试验了一种“水冷复合炉墙”,通过13个月的生产考验,寿命达1265炉(一个炉役期),证明该炉炉墙具有寿命长、节约镁砂、减轻劳动强度、提高生产率等优点,具有很大的经济价值.同时,对增碳、氧化速度、钢水温度等问题进行了分析. In order to solve the problem of reducing the lining life after using high power and oxygen blowing smelting operation in a steel-making electric arc furnace, we tested a “water-cooled composite furnace wall” on a 1.5T electric arc furnace and passed the 13-month production test, 1265 furnace (a furnace period), which has proved that the furnace wall has the advantages of long life, saving magnesia, reducing labor intensity, increasing productivity, etc., with great economic value.At the same time, the carbon, oxidation rate, molten steel temperature The problem was analyzed.
