Magnesium Aluminum Spinel Bricks For Cement Rotary Kiln


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 1800째C in an ultra-high temperature tunnel kiln, and the refractoriness is above 2000째C. 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.

Features:

Magnesium aluminate spinel brick is a new product developed by our company according to the development current situation of building material industry and the performance characteristics of all kinds of lime kilns.

The product has the advantages of good alkali-resistance, good erosion resistance, good thermal stability, high crushing strength,and high refractoriness under load.
