The classification of magnesia brick

Can divide commonly for agglomeration magnesia brick (say again firing magnesia brick) combine magnesia brick with chemistry (say not to burn magnesia brick again) two kinds big. Purity and firing the magnesia brick with high temperature, as a result of

Grain is contacted directly, call direct union magnesia brick; The brick that makes for raw material with electric frit magnesia calls magnesia brick of electric frit recombine.

Magnesia brick has taller fireproof degree, function of very good broken bits of alkali resistance sex, loading bate begins temperature tall, but heatproof shake performance is poor. Agglomeration magnesia brick is raw material with making bricky magnesia brick, via smashing, burden, mix practice, after shaping, in 1550 ～ the high temperature of 1600 ℃ falls firing, high pure of goods firing temperature is in 1750 ℃ above. Irrigating magnesia brick is proper chemical bond is added in magnesia, via mixing refine, shape, dry and make.
