Refractory Silica Bricks Zibo Shunzhou International Trading Co., ltd is a specialized manufacturer and supplier of refractory, we can supply many kinds of refractory products, such as silica bricks,high alumina bricks, fireclay bricks, low porosity fireclay bricks, insulating bricks and many kinds of refractory castable, ramming mass etc. We have exported to USA, India, Germany, Canada etc many countries, and they are satisfied with 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 ahigh 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.
