Detailed Product Description

TR series of fired magnesia refractory brick using high-quality or high-purity fused magnesia and chrome ore as raw materials, make into by high-pressure, high temperature sintering, according to the need to be adjusted CR2O3 content, characteristic with big crystal, high combined rate in direct, mainly component are the periclase and chrome spinel, the product own good crack resistance, it is the ideal furnace lining materials of the smelting, building materials industry and high temperature furnace.  

 Product features:

 Excellent strength of abrasion proof,anti-erosion,bending strength, low porosity and stable volume

 Excellent anti-oxidation, anti-slag, anti-erosion ability;

 Easy-to-skin hanging in the kiln, and low thermal conductivity;

 High temperature of  refractoriness under load  

 Excellent performance of high-temperature firing, high rates of associative property ,anti-erosion ability

On the basic material is strong resistance to acid resistance of magnesia refractories than good. Strong resistance of basic material, better resistance of acid material than magnesia refractory   

   Product application:

 Metallurgy industry of open-hearth furnace top , electric stove top, Mixer etc.

 RH, VOD, AOD, and other refining installations;

 Non-ferrous metallurgical furnace, vacuum treatment plant;

 Building materials industry, glass furnace regenerator; cement rotary kiln calcination etc.
