Stoving hot-blast stove uses firebrick, with where to plant appropriate?

Stoving hot-blast stove is a kind of device that is used at stoving stock, need is used can bear the firebrick of high temperature and thermal shock. Be aimed at the use requirement of stoving hot-blast stove, general choice is the following the firebrick of two kinds of types:
Saggar brick: Saggar brick is a kind of commonly used high temperature fireproof material, make by the material such as clay, kaolin. The main characteristic of saggar brick is thermal stability good, mechanical intensity is high, can bear high temperature, high pressure and thermal shock.
Fireproof tall aluminous brick: Fireproof tall aluminous brick is a kind of high temperature that makes with the material such as kaolin, silica fireproof material. Fireproof the main characteristic of tall aluminous brick is sex of shake of high strenth, heat-resisting good, be able to bear or endure aggressivity is strong, can bear high temperature and soda acid are eroded.
When choosing firebrick, need the element such as temperature of the specific use condition according to stoving hot-blast stove, job and caustic material to have integrated consideration, choose suitable firebrick. Generally speaking, if stoving hot-blast stove is in-house,temperature perhaps exists higher stronger soda acid is corrosive, proposal choice is fireproof tall aluminous brick; If internal temperature is opposite inferior, and caustic weaker, can choose saggar brick.
