Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.

Refractory bricks are dense shaped refractory material. with high refractoriness and mechanical behavior under high temperature, refractory bricks is the necessary material of high-temperature services, mainly used for industrial furnaces and kinls and several thermal equipments.

Refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength.

They are primarily used for furnaces and kilns in metallurgy, steel, power, chemical industry, and electric power and machine building etc areas
