Cold Ramming Carbon Material for Blast Furnace
You may submit your questions by filling the form.
The cold ramming carbon materials stipulate the classification and technical requirements for the cold carbon materials used in the blast furnace and the aluminum electrolysis tank.
Classification: cold carbon materials are divided into two varieties and five brands. 1. the cold tamping material for the blast furnace (1).HT-1 is suitable for the joints between the bottom of the furnace and the filling of the carbon block or the small blast furnace lining. (2).HT-2 is suitable for the gap between the lining of the blast furnace and the cooling wall (or the shell). 3) HT-3 is suitable for blast furnace iron mouth and sand mouth. 2. Cold ramming carbon material ( 1 ) HT-1 for aluminum electrolytic cell is suitable for the joint between aluminum electrolytic cell cushion and filling carbon block or small electrolytic cell lining
