Zhengzhou Sunrise Refractory Co. Ltd has the abundant high quality materials and convenient transportation, provide favorable conditions for the production of the refractory materials. After 20 years of hardworking and development, it has become a comprehensive enterprise producing refractory materials in metallurgy, building materials, electric power and chemical industry, etc.
The products are fused magnesia as main raw material, after a reasonable size distribution, high pressure forming, high-temperature sintering. The product has strong resistance to slag corrosion ability and high temperature dimensional stability.
Magnesium oxide doesn’t fuse with carbon when magnesia carbon brick is used under high temperature, therefore, keeping the good refractory performance of the original components. Furthermore carbon is featured with good thermal conductivity, low thermal expansion and elastic coefficient, which effectively prevent spalling and slag penetration, thus greatly change the weakness of the magnesia refractory, such as the slag penetration.
In addition, because of the wettability of carbon for the slag, mgo c bricks have good corrosion resistant performance.
Magnesia carbon brick, as a kind of composite refractory materials, takes advantage of the strong slag erosion resistance ability of magnesia and the high thermal conductivity as well as low expansibility of carbon, which effectively makes up for the spalling resistance, which is the biggest disadvantage of the poor magnesia.
In conclusion, because mag carbon bricks belong to mgo c refractories, so such products have good high temperature performances, such as good thermal shock resistance, corrosion resistance, spalling resistance, and low high temperature creep rate, becoming the ideal materials used on the furnace.
The regular magnesia bricks are made from dense dead burned magnesia that makes the bricks in good refractoriness, corrosion-resistance, Mainly used in glass furnace regenerator, the upper part. Such as, checker chamber of glass tank, lime kiln, non-ferrous metallurgical furnaces, open heart furnace, iron mixer and EAF of steel-making, and also ferro-alloy furnace, etc.
