The important role of alumina hollow ball in various products

Alumina hollow ball has a low density, high porosity characteristics, its internal hollow structure can effectively reduce the thermal conductivity, significantly enhance the thermal insulation effect of alumina brick.

Advantages and Physical Properties of Alumina Hollow Sphere

Alumina hollow balls have good temperature resistance, high stability after heating, and a simple structure that can effectively reduce the weight of the furnace body. It can also achieve energy-saving effects during use and reduce losses. The wear percentage of alumina hollow balls is low. , the following introduces the advantages and physical characteristics of alumina hollow spheres.

Smelting process and properties of alumina hollow spheres

Alumina hollow spheres use industrial alumina as raw material, and can be made into very light alumina hollow spheres by electromelt blowing. The lightweight refractory insulation brick made of this kind of hollow sphere can be used for the lining of high-temperature furnaces that are in direct contact with the flame.

Advantages of lightweight refractory alumina hollow spheres?

1. High operating temperature: up to 1750 degrees or more, good thermal stability. The change rate of the reburning line is small, and it can be used for a longer period of time.

Alumina hollow ball installation precautions

The steel grid structure with welded alumina hollow ball nodes has the characteristics of large span, high strength, light weight, beautiful appearance, and no need for support. So what are the precautions for the installation of alumina hollow balls?
