Corundum refractory castable

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 .
