Middle grade magnesite

Description

In our country, high purity magnesite was tried to burn by oil shaft kiln and turned to merchandise in eighties, but the output is small, Almost in the meantime, coke shaft kiln further burned middle grade mag-nesite were launch, butburned with coke could increase the silicon but depress magnesite&#**9;s grade low, so we built middle grade magnesite oil shaft kiln. The first stept burned middle grade magnesite is a little lower than the futher one, but it can meet the demand to produce DMC*9A, DMC*9B, it can manufanture fine semidirect Magnesite Chrome bricks, Casting Material and gunning mix, etc. HMS*4Bï&frac*4;šIL<0.3% , SiO2<2.5% , CaO<1.8%, MgO>*4.5, B.D(g/cm3)>3.*0; HMS*4Aï&frac*4;šIL<0.3% , SiO2<2.0% , CaO<1.6%, MgO>*5, B.D(g/cm3)>3.*0ï&frac*4;› HMS*5Bï&frac*4;šIL<0.3% , SiO2<1.6% , CaO<1.8%, MgO>*4.5, B.D(g/cm3)>3.*5ï&frac*4;› HMS*5Aï&frac*4;šIL<0.3% , SiO2<1.4% , CaO<1.6%, MgO>*5, B.D(g/cm3)>3.*6ï&frac*4;›
