Causes of damage to refractory bricks

Refractory brick is a kind of refractory material made of refractory clay or other refractory material. Refractory bricks are consumables, so what is the cause of the damage?

1, refractory bricks are chemically corrosive to each other

2, chemical corrosion of slag (including chemical corrosion of furnace dust). It is usually the main factor of lining corrosion of refractory bricks in smelting furnace.

3, chemical corrosion of furnace gas. Mainly refers to the refractory at high temperature oxidation furnace gas gradually oxidized corrosion.

4, because of the high temperature caused by high temperature melting.
