As is known to all, the raw material of magnesite brick is mainly magnesite, and its basic component is MgCO3, which can become sintered magnesite after calcined at high temperature and then broken to a certain size. Zhengzhou Rongsheng Kiln Refractory Co.,Ltd. in the production of magnesia brick has advanced technology and technology, high quality magnesia brick, high quality, stable and reliable, welcome to purchase.
High quality magnesia brick is a kind of basic refractory material with the content of magnesium oxide above 90% and the main crystal phase is square magnesite. Generally speaking, common magnesia brick uses dense sintered magnesia as raw material, which has high fire resistance and corrosion resistance. It is widely used in open hearth furnace, mixed iron furnace, titanium alloy furnace, electric furnace and so on. In addition, magnesia bricks with MgO content of more than 95% are generally calcined magnesia or electrofused magnesia as raw materials. After ultra-high temperature firing, the direct bonding rate is high and the corrosion resistance is strong. Therefore, magnesia bricks are widely used in various high-temperature kilns.
Magnesite brick advantage：
1. Strong resistance to alkaline erosion;
2. Strong anti-erosion ability;
3. Excellent thermal stability;
4. High compressive strength;
5. High softening temperature under load.
We are high quality magnesia brick manufacturer, this series of refractory brick is mainly used in the bottom and wall of electric furnace, basic open hearth furnace for steelmaking, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high-temperature tunnel kiln, lining of cement rotary kiln, heating furnace and so on. Importantly, magnesia brick is mainly used for paving the surface layer of the bottom of the furnace and the lower part of the wall of the soaking pit. Because it can resist the erosion of iron oxide.
The refractoriness of magnesia brick can reach above 2000℃, and its softening temperature under load varies greatly with the melting point of cement phase and the amount of liquid phase produced at high temperature. The beginning temperature of general magnesia brick softening under load is between 1520℃ and 1600℃, and the fireproof degree of high purity magnesia brick can reach 1800℃ .
We are a high quality magnesia brick supplier, specializing in the production of various types of refractory materials for more than 20 years, and more than 60 countries to achieve friendly cooperative relations with customers, welcome to consult and purchase, we will give you the most comprehensive, the most intimate service.
