Specifications

Refractory castable is a kind of material made by mixing the granular and powdered materials with a certain amount of binder composition and water together. It is an amorphous refractory with high mobility, it can be used with casting method of construction but be hardened without heating. It is made from refractory aggregate, powder, binder, additives, water, or other liquid material. In general it can be used with molding method of site casting, vibrating or tamping, also a preform can be made in use.

Castable Refractory Features:

1.Good construction performance.

2.High strength, good bulk stability.

3.Good insulation, high temperature resistance, good thermal shock resistance.

4.Good slag resistance, good resistance to abrasion.

5.Good corrosion resistance.Scouring resistance

Castable Refractory Application:

1.Used as lining turning kiln, hot converter lining heat treatment furnace.

2.Furnaces of metallurgy industry, chemical industry and construction industry.

3.Circulation part of furnaces.
