Sintered & Fused Spinel |
Compound
Magnesite-Alumina
Spinel |
Synthesized
from industrial Alumina or high grade bauxite with caustic calcined
magnesite, sintered in high temperature rotary kiln. It is mainly
used as secondary material in middle and small ladle casting materials,
high grade Spinel is large ladle casting and as the main material
of large cement kiln spinel and magnesite spinel. |

Compound
Periclase Spinel |
|
Chromyl
is a kind of pollution we have to find ways to dispose of. Spinel
compounded with periclase can solve the above problem. It is an
relatively ideal green refractory material. |

Fused
Magnesite-Chrome Spinel |
|
Fused
magnetite-Chrome Spinel with high Chrome is made mainly from high
purity caustic calcined, concentrated chrome ore and chrome ore
through electro-fusing. It is the important material of Rhand VOD
vessel, Non-ferrous smelter and eye bricks. |
