Product Description
Furnace, Kiln, Stove heat holding Castable
As a ten year old refractory material manufacturer, we have worked with many steel plants, metallurgic plants, cement plants, glass plants, provided them with top notch products and services. Here are the refractory bricks we produce:
Products
1.Magnesia-chrome refractory brick
By sintered magnesia and chrome ore as the main raw material in appropriate proportion, is made of high-grade refractory material. It shows better volume stability, strength at high temperature and sensitivity to the small thermal shock.

3.Loose castable refractories
By reasonable distribution of the granular and powdered materials and the binder composed of not forming and firing directly for the use of the refractories. This kind of material has no fixed shape, which can be made into slurry, mud paste or loose shape.
