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.
Magnesia Bricks Description
Our company's magnesium-aluminum spinel series products are currently widely used in lime kilns. This series of products has the advantages of good thermal stability, good slag resistance and strong corrosion resistance. This product replaces magnesia-chrome bricks and magnesia bricks in key parts of lime kilns, and has achieved good results.
Magnesia Bricks Features:
It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stablity in high temperature.
