Corundum Block Ty-G93

Main mineral component of corundum brick is corundum phase, it has excellent physical property in high temperature, resistance to chemical corrosion. It is widely used in lining of ovens of petrochemical industry; bottom of steel rolling mill and in the second-stage converters of the 300000t ammonia synthesis furnaces, steel notch.

Application:
Fused corundum block is mainly used in key parts of the industrial furnace that require high abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical furnaces, the tapping platform (tapping spout) style walking beam furnaces, and also as the interior for destructors.

Our bottom block is made from high quality raw material, processed by fine batching, forming, drying and firing process. After that the block will be matched by cutting, grinding, milling and drilling to assure of the accurate sizes.
The physical and chemical properties of our bottom block are excellent, the appearance and size are accurate, especially the anti hydrogen diffusion ability and anti alkali erosion ability of the product are remarkable.
This block can be used in the whole bottom of floating glass tin bath.

Clay brick

Our main exporting brand of refractory bricks are:

Direct bonded magnesia-chrome bricks
ííííthe product is manufactured by taking high purity magnesia and high quality chrome as raw materials through the process of high pressure moulding and high temperature burning.It has a good thermal shock resistance and volume stability and is applied in the cement and glass industries.
