Unshaped Insulating Refractory qv Gunning Castable Wear Resistance As Furnace Lining
Unshaped Insulating Castable Refractory Wear Resistance As Furnace Lining
Description:
This product uses synthetic materials including high-quality bauxite,corundum and silicon carbide which are proceeded by specific equipment,as the main material,compound with many admixtures and high-efficient water reducing admixture,and fluidizing admixture to improve the workability and flowablity.the main characters are:it could be applied in narrow environment where is not vibratile(if possible,it could be rammed by person),only rely on its deadweight and push by the potential energy without vibration.it has good construction and quality performance,and is mainly used in circulating fluidized bed boiler furnace lining and other construction sites in the furnace lining which are hard to implement.
