Fused rebonded magnesite chrome brick
Introduction:
The fused rebonded magnesite chrome brick, also known as fused magnesia chrome brick. Its refractoriness under load is up to 1740 °C. Generally, calcined magnesia and chrome ore are used as raw materials, and they are melted into fused magnesia chrome sand by electric furnace, and then obtained by crushing, grinding, compounding, molding and firing.
Advantages:
1. Low thermal expansion coefficient
2. Good thermal shock resistance
3. Resistance to acid-alkaline slag erosion
Application:
1. Open-hearth furnace roof
2. Electric furnace roof
3. Refining furnace
4. Non-ferrous metal smelting furnaces
