Burned Magnesite |
|
|
Dead
Burned Magnesite (DBM) is produced with selected natural magnesite
through purifying, Calcining in Shaft Kiln. It's an ideal material
for making bricks and unshaped refractory materials, the final products
are used in electric furnace bottom and furnace's lining tamping. |

High Purity Magnesite |
|
|
It
is made of selected superfine magnesite. It goes through the process
of mine-selecting, calcining, careful grinding, ballshaped making
and forging in super high temperature oil shaft kiln. It is an ideal
material for producing bricks, unshaped refractory materials. |
