Product Description

Corrosion-resistant furnace lining insulation castable alumina hollow ball castable for boilers

Product Description

Alumina Bubble Castable

Alumina Bubble Refractory Castable (Alumina hollow ball castable) is a lightweight refractory castable prepared with alumina hollow ball as aggregate and industrial alumina or corundum powder as powder. The refractoriness is 1800ºC, it has good high temperature resistance and can work stably in high temperature environment.

Characteristics of Alumina Bubble Castable

1. Alumina hollow ball lightweight castable: can effectively reduce structural burden and reduce energy consumption.
2. Good compressive strength ensures the stability and durability of the structure.
3. Good high temperature resistance, can work stably in high temperature environment.
4. Good thermal insulation performance can effectively reduce the loss of heat energy.
5. It has good wear resistance and can withstand certain wear and impact, extending its service life.
6. Good chemical corrosion resistance, can work stably in corrosive environments such as acid and alkali.

Product Application

Alumina Bubble Castable Applications

Alumina Bubble Castable(Alumina hollow ball castable) is very stable in various atmospheres and is an ideal thermal insulation material for high-temperature lining. Especially used in high-temperature kilns at 1800 ºC, it can be used as high-temperature insulation filler, and has good effects on various types of thermal furnaces such as inverted flame kilns, shuttle kilns, molybdenum wire furnaces, tungsten rod furnaces, induction furnaces, nitriding furnaces, petrochemical industry gasifiers, carbon black industry reaction furnaces, metallurgical industry induction furnaces, etc., in reducing furnace weight, reforming structures, saving materials, and saving energy.

Packaging & Shipping

Packaging: 25kg/bag, two layers kraft bag with water proof, and with ton bag outside or each ton packed on a fumigation pallet according to customers' request.
