1. It shall have sufficient fire resistance and load softening point. Because under the action of electric arc, the internal standard temperature of different parts of furnace lining can reach 1300-1500 degrees.
2. It shall have strong slag resistance. Because the slag and smoke penetrate into the interior through the pores of the furnace lining at high temperature, the refractory is damaged, which requires spraying curing agent on the surface of the ceramic fiber module for protection.
3. It shall have good thermal shock resistance. Because in the process of steelmaking, opening the furnace door and lifting the furnace cover will suddenly change the temperature of the lining refractory, which may lead to spalling and cracking.
4. It shall have stable chemical properties and shall not be easily corroded by furnace gas.
5. The thermal conductivity should be small and the conductivity should be low.
