一、电弧炉炉衬耐火材料 1.选用电弧炉炉衬材料的一般原则是:①由于炼钢炉温度一般为1500~1800℃,所以要求炉衬耐材须有足够的耐火度和荷重软化点。②炉衬表面受高温炉渣的侵蚀,因此要求有较强的抗渣性能。③炉衬的冷热变化急剧,要求耐火材料应有较好的耐急冷急热性。④还要求炉衬耐材具有足够的强度、小的导热系数和低的导电率等。
First, the EAF lining refractory 1 arc furnace lining material selection of the general principles are: ① As the temperature of the steel furnace is generally 1500 ~ 1800 ℃, so the lining refractory material must have sufficient refractoriness and load softening point. ② lining surface by high temperature slag erosion, so require a strong slag resistance. ③ lining rapid changes in the hot and cold, requiring refractory materials should have better resistance to cold and heat. ④ also requires refractory lining with sufficient strength, low thermal conductivity and low conductivity.
