目前世界各国在提高出钢槽及盛钢桶的使用寿命上都广泛的试用在衬砖工作层上喷涂一层耐侵蚀的胶质耐火材料。1964年12月鞍钢第三炼钢厂与钢铁研究所一起试验了出钢槽涂料,通过实践已收到较好的效果。试验是在370吨固定式平炉上进行的,使用双流出钢槽,出钢时间为10～20分钟,出钢时经由出钢槽流出的渣量平均约为16米~3,渣中氧化铁含量约9～14%。
At present, all countries in the world have tried extensively on the service life of tapping troughs and steel ladle to spray a layer of corrosion-resistant gypsum refractory on the working layer of lining bricks. In December 1964, Anshan Iron and Steel No. 3 Steel Works and Steel Research Institute experimented with steel trough coating, the practice has received good results. The test was carried out on a 370-ton stationary hearth furnace with a double outflow tank with a tapping time of 10 to 20 minutes and an average of about 16 to 3 slag flows out of the tapping tank during tapping. Iron oxide Content of about 9 to 14%.
