This product is characterized by iron corrosion resistance, alkl ali corrosion and slag corrosionresistance of the traditional ceramic cup as well as high thermal conductivity of the carbon bricks, which is being used forBF ceramic cup, tuye re, iron notch and slag notch as a new kind ofrefractory. Meanwhile, the productshave solved the problems such as poor thermal stress of the traditional ceramic cup and poor iron corrosion resistance and poor oxidation resistance of carbon bricks resulting inmlcropore .
