Self-flow Refractory Castable for Back Lining

Self-flowing refractory castable is a kind of fluidity refractory castable after fired and mixed with water. Aaggregate, powder, glue will be combined according to technical PRO ratio rate. Self flowing refractory castable is up to the filling of complicated and special sizes places. Usually, self flow refractory castable could be high alumina type, corundum type, mullite type, etc.

Self-flow Refractory Castable Characteristics:

• Easy use when construction
• Convenient and efficient
• High intensity
• Completion period for construction will be shortened
• Labor-saving

Self-flow Refractory Castable Application:
Self-Flow Refractory Castable High Alumina Castable can be used for continuous casting intermediate tank lining, electric furnace top triangle area, steel outlet, steel barrel, heating furnace, blast furnace iron ditch, CAS furnace, cast iron induction furnace, boiler protection pipe, etc.
