The Main Factors Of Furnace Cover Life

The main factors of  furnace cover life

1. Temperature changes caused by the arc heating, tapping and  movement of the furnace cover .

2. Chemical erosion. Molten slag spattering to the surface, causing chemical erosion, as well as the effection of CO, CO2 and SiO2 in the furnace;

3. Arc radiation. Melting loss caused by thermal radiation ;

4. Wear of high speed airflow caused by high speed dust extraction in the furnace; therefore, the refractory materials for the furnace cover must have good thermal shock, corrosion resistance to high temperature splashing, and good integrity, firm structure and no cracking.
