| Name: | Kiln Refractory Bricks |
Magnesium Aluminum Refractory Fire Bricks , Industrial Furnace Refractory Bricks
Description:
Mainly used for steel-making basic open hearth and electric furnace bottom and furnace wall, the permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesite brick and cement rotary kiln lining, furnace bottom and furnace wall, glass kiln regenerator checker brick, etc.
Features:
1. High temperture resistance
2. corrosion resistance
3. High degree of refractoriness,
4. good resistance to alkaline slag,
5. high temperature of load .
6. low thermal shock resistance.
Composition:
Sintered magnesite brick is made of brick and magnesia brick as raw material, after crushing, batching, mixing, molding In 1550 ~ 1600 ℃ high temperature firing, high purity products sintering temperature above 1750 ℃. No magnesia brick is added to the magnesium sand to add proper chemical binding agent, through mixing, molding, drying.
