Products introduce:
Our production made of high-quality low ash materials,such as pertroleum coke,needle coke and coal pitch.
From calcining,burdening,kneading,forming,baking to pressure impregnation,graphitization.We pay attation to every detail to make it boutique.
We know machining is very important,so we precision machined with professional CNC maching to make sure high quality.
Such of the products own characteristics with low resistivity,good electrical conductivity,low ash,compact structure,good antioxidation and high mechanical strength.
Our main products:
Refractory material for industrial furnaces, such as Graphite electrode high-alumina brick, clay brick, silicon brick, high-strength diatomite brick, light weight insulation brick, low iron mullite brick, etc.; anti-stripping alumina brick, alkali proof brick, phosphate brick for cement industry; For the industrial furnace and power boiler, we can provide abrasive brick, corundum brick, mullite brick, wear resistant castable, corundum castable, high strength low cement castable, impervious material, plastic refractory, etc. Our products are popular in the whole country and have been exported to India, Iran, etc.
