Description

Magnesia brick is still important lining material for ferrous, non-ferrous metal and glass industry kiln.HMZ****2 is produced by HMS*8A clinker, the material C/S>2.0, microstructure is reasonable, the base phase is C3S\C2S , has good character of slag resistance, the content for HMZ*3 is special and it is a specialism products for ferroalloy fumace, can get same effect with middle grade magnesia brick.HMZ*5 often be used for regenerator of glass fumace, but the checker brick for up and middle place of the regenerator are HMZ****2 and rebond magnesia ***** temperture in the middle and up regenerator place can reach ********0�, there is much K2O\Na2O\SiO2 in powder, the more pure for magnesia brick (including mgo-cr brick)the deeper for the ***** in the brick diffuse to the ***** will raise the melting point and lead to the magnesite frame flaking, surface thickening, wall up the channious in MgO*5% grade magnesia bricks.
