1. It should have sufficient refractoriness and softening point under load. Because under the action of the electric arc, the internal standard temperature of different parts of the furnace lining can reach 1300—1500 degrees.

2. It should have strong slag resistance. Because the slag and smoke penetrate into the interior through the pores of the furnace lining at high temperature and damage the refractory materials, it is necessary to spray curing agent on the surface of the ceramic fiber module for protection.

3. It should have good thermal shock resistance. Because in the steelmaking process, opening the furnace door and lifting the furnace cover will cause the temperature of the refractory material of the furnace lining to change suddenly, which may cause spalling and cracking.

4. It should have stable chemical properties and not easily corroded by furnace gas.

5. The thermal conductivity should be small and the electrical conductivity should be low.
