Fire Light weight mullite insulation brick

Brand:aa

Product detail:

ZIBO HITECH MATERIAL CO., LTD is the specialized manufacturer and supplier of refractory in China, Our products mainly include refractory bricks, refractory castable, refractory precast shape, insulating brick etc. For refractory castable and precast shape they are very popular in the Europe, North American area.

 

Our Refractory Brick: with high refractoriness and mechanical behavior under high temperature,

Refractory brick is the necessary material of high- temperature service, mainly use for industrial furnaces and kilns and thermal equipments.

 

For the light weight brick,it will be created a lot of stomatal in the production process,so the bricks'  contraction is bigger (about 10%),and the  three directions contraction is also not the same,and the  bricks have large deformation  in the process of drying and firing.So it is very difficult to control the demension.
