Corundum refractory castable,This type castable use different artificial materials like high bauxite,corundum,carborundum and others as main materials according to different grades and also mix with many kinds of additives , superplasticizer and flowable agent to increase the materials’flowing property. Its main characters are : it is only depend on itself weight and the promotion of potential difference to make it flow on the condition that no increasing of water consumption ; and make it could do construction in crevice and place where couldn’t beat on the condition that no shaking ; good workability ; mainly used in where it is difficult to do construction and severe wear parts .

Our advantages :
- We have engaged in the refractory materials from year 1994 , so we have very rich experience.
- Our engineer is one of the best of the exist two experts in our country . many other technicians came to our factory to learn when they met difficulties from our engineer –Mr Wang.
- We have several types patented refractory materials that other factory couldn’t manufacture.
- Our factory is the first one to get government permit for manufacturing when there is strict policy for protecting environment.
- We are expert in the CFB boiler project and also have built many projects around our countries.
