High Alumina Castable Description

High alumina castable is a kind of refractory castable which uses high alumina raw material as aggregates and the powder and then be added with binding agent. High aluminum refractory castable has high mechanical strength, good thermal shock resistance, good corrosion resistance. high alumina refractory castable is an amorphous refractory with high mobility, refractory high alumina castable is made from refractory aggregate, powder, binder, additives, water, or other liquid materia. high alumina castables can be used with molding method of site casting, vibrating or tamping, also a preform can be made in use and can be used with casting method of construction but be hardened without heating.

Properties of High Alumina Castable

  • High intensity,
  • Volume stability,
  • Good insulation,
  • Acid resistance,
  • High temperature tolerance,
  • Good thermal shock resistance,
  • Good slag resistance,
  • Good wear resistance,
  • Good corrosion resistance,
  • Construction is convenien.

Five-step Production process of High Alumina Castable

Select the raw materials of high aluminum casting materials according to the formula.
Calculate the gradation and dosage of aggregate, powder, binder and additive according to the raw material formula, and strictly control the aggregate powder particles.
Put the weighted aggregate and powder into the blender one after another, and then pour the powder into the aggregate and stir for 8-10 minutes.
Put the stirred high aluminum pouring material into the ton bag, equipped with additives and binder, and then package.
The packed high aluminum pouring materials shall be stored in the warehouse, and the date shall be marked and moisture-proof and waterproof.

Advantages of High Alumina Castable
