Magnesia-chrome brick is an alkaline refractory material fired from chrome ore and magnesia. The main components are chromium oxide and magnesium oxide.Good thermal stability, it is sintered at a high temperature above 1800°C in an ultra-high temperature tunnel kiln, and the refractoriness is above 2000°C. The performance of resistance to sudden temperature change and resistance to alkaline slag is good. Used for laying steel leveling furnace, steelmaking electric furnace, non-ferrous metal smelting furnace, cement rotary kiln lining, RH refining furnace. This kind of brick has high fire resistance, high temperature and high temperature strength, strong erosion resistance to alkaline slag, good thermal stability, and also has a certain adaptability to acid slag.

1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable for various atmosphere.
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely.
4. Product specification: standard form, normal standard, shaped and special shaped bricks.
5. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.
The bricks are packed on wooden pallet with papers in each layer and PP film wrapped outside of the whole pallet.
