Magnesite
- Alumium bricks are made by the mixture of magnesite and
bauxite. It used to be the special products for flat furnace,
and currently it is often used for Non-Ferrous. |

When
the smelting temperature is high, molten steel erode serious,
or the dreg series are S-F, fused rebounded products are sole
superior. The FRC Bricks are made by Fused Magnesia Chrome
smelting grain, high Purity Fused Magnesia and Chrome, it
is mainly used in Non-Ferrous rotary furnace VOD¡¢AOD¡¢SKF¡¢LF¡¢RH

Magnesia
Carbon Bricks |
|
The
magnesia carbon bricks are manufactured by using high purity
fused magnesite in coarse crystals and flake graphite as raw
materials; the thermosetting and thermoplastic phenol resins
as binders through high pressure shaping. They are characterized
by high hot strength(MOR), good corrosion and erosion resistance
and oxy-resistance, well used in hot-point and slag-line of
UHP, HR and DC arc furnaces, etc. |
