The Principle of Choosing Refractory Materials of Different Parts for Cement Kiln (Part 2)
?Transition Part and Baking PartTransition Part: The skin of the kiln is not stable of this part; the liner should have thermal shock resistantance, low thermal conductivity and abrasion resistance property. Many countries adopt magnalium spinel brick, but this kind of brick is high thermal conductivity and this will lead to thermal loss, let alone energy saving. The domestic Guimo brick can fulfill the needs of this part. ?Baking Part: The temperature of this part is high, the chemical reaction is fury, so we need a kind of brick which can resist the corrosion of SO3 and CO2.. The magnalium spinel brick is difficult to be sticky to the skin of the kiln, the dolomite brick has poor shock resistance property, the magno ferrite brick from overseas has good effect but the price is very high. The new adopted low chrome periclase spinel brick compound in China has good reputation.
