Alumina Hollow Ball Castable Meaning
Alumina hollow sphere refractory castable mainly relies on the pores of the hollow ball raw material and the pores in the product matrix to obtain higher thermal resistance. When the porosity of the product is constant, the more dispersed the pores inside the product, the smaller the pore diameter, the greater the convective heat transfer resistance inside the pore; meanwhile, according to the scattering principle, the resistance of phonon heat conduction and photon heat conduction is increased, and the radiation heat transfer is reduced.
Alumina Hollow Ball Castable Features
1.Alumina hollow ball castable is characterized by high load softening temperature, high strength and good heat insulation performance.
2.Hollow ball refractory castables are characterized by high load softening temperature and high strength, so the service temperature is generally 1500~1700 degrees Celsius.
3.Alumina hollow ball castables with high softening temperature, high strength, good thermal insulation performance, carbon black reaction furnace and high temperature special lining permanent layer, refractory castable alumina hollow ball is ideal thermal insulation material.

Alumina Hollow Ball Castable Application
1.Alumina hollow ball refractory castable used in industrial ceramics, structural ceramics, electronic ceramics, petrochemicals, metallurgy, coal chemical and other high-temperature kiln linings and thermal insulation materials for ultra-high temperature furnaces.
2.Alumina hollow ball refractory castable is an ideal insulation material for carbon black reaction furnace and high temperature special inner liner.
3.Fireproof castable alumina hollow ball has been widely used in high-temperature and ultra-high temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reactors, metallurgical industrial induction furnaces, etc. refractory castable has achieved very satisfactory energy-saving effects.
4. Refractory castable alumina hollow ball can be used for high temperature energy saving (>30%) downdraft kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace. Refractroy castable will achieve obvious results in reducing the weight of the furnace, transforming the structure, saving materials and saving energy.
Alumina Hollow Ball Castable Manufacturing Process
1.Alumina hollow ball refractory castables mainly CA-70 or CA-80 cement, combined with clay, aluminum sulfate and aluminum sulfate. Refractory castable using industrial alumina powder or corundum powder as materials for refractory powder, fine. The degree is less than 0.09mm, accounting for more than 90%, the refractory hollow sphere castable has a maximum particle size of 5mm, castable refractory is naturally graded or graded. In addition, additives should be added after the admixture to improve performance.
2.Alumina hollow sphere refractory castable and refractory products are lightweight refractory materials with high temperature resistance and energy saving, castable refractory are very stable in various atmospheres. Especially for use in high temperature kiln furnaces of 1800. Hollow balls refractory castable can be used for high temperature, ultra high temperature insulation fillers, high temperature refractory concrete lightweight aggregates, high temperature castables. The alumina hollow sphere refractroy castable is the main body, fireproof castable can be made into various shapes. The maximum use temperature with the alumina hollow sphere refractory castable is 1800℃. The mechanical strength of the refractory product is high, which is several times that of the general lightweight product, and the bulk density is only one-half of the corundum refractory castable.
