High Aluminum Refractory Castable

High Aluminum Refractory Castable Introduction

High-alumina refractory castable is high-alumina raw materials for the aggregate and powder, adding the binder made of refractory castable. With high mechanical strength and good thermal shock resistance, abrasion resistance and other properties, mainly used for boilers, blast furnace hot stove, heating furnace, ceramic kiln and other furnace lining.
