通过对有芯工频炉酸性炉衬生产欧元材料出现的问题进行分析 ,发现在使用有芯工频炉酸性耐火材料时 ,炉衬寿命大大缩短 ,并使铜液Si含量超标 ,造成材料报废。而炉衬材料换成中性耐火材料时 ,基本上控制了Si含量 ,达到了欧元材料标准 ,并使炉衬寿命大大提高 Through the analysis of the problems arising from the production of euro material by the core with frequency furnace acid lining, it was found that when using core frequency furnace acid refractory material, the lining life is greatly shortened, and the Si content in the copper solution exceeds the standard, resulting in material scrap. The lining material into a neutral refractory material, the basic control of the Si content, reached the euro material standards, and to greatly increase the life of the lining
