在西纳尔斯克钢管厂10-C1型混铁炉熔池的内衬中已对彼尔沃乌拉尔斯克硅砖厂生产的2牌试验镁尖晶石碳砖进行了工业试用。试验耐火材料的使用效果比牌或者牌刚玉制品高1.5～2.0倍。2牌耐火材料的寿命受碳的氧化速度的影响。
An industrial trial of 2-brand pilot magnesium spinel carbon brick produced at the Silverskiy Bilbao factory in Bilbao has been carried out in the lining of the 10-C1-type mixing furnace pool at Sinnarsk Steel Works. Test the use of refractory than brand or brand corundum products 1.5 to 2.0 times higher. The life of 2-brand refractory materials is affected by the rate of carbon oxidation.
