In recent years, of our countryFireproof materialIndustry gained very great success, mastered the production of all sorts of grade firebrick, among them, what ought to put forward especially is the brick mixes Molaishi againThe manufacturing technology of crystallization corundum brick. Mo Laishi brick besides have very tall fireproof degree beyond, still have very high density and mechanical strength. Itself of recrystallization corundum goods is had very tallfireproof spend and receive the strength that is bordering on a metal. Master the production with plasticity chromic arenaceous mine, settled the need of dynamical project directly, because it has a lot of valuable property, accordingly byUse the inserts that is in charge of to take the water-cooling wall of thorn widely, reduced the construction of firebox of high fever stress.
