Sunrise refractory high-grade insulation brick introduction

Insulation bricks are heat insulation materials. Most products are not used at high temperatures and can only be used for insulation and insulation. Today, Sunrise Refractory is a small-scale insulation brick for 1500 degrees. It is helpful to everyone.

 

1. Alumina hollow ball insulation brick, alumina hollow ball brick is an insulating refractory product made of alumina hollow sphere as the main raw material. It is mainly used as a thermal insulation layer for high temperature industrial livestock linings and high temperature thermal equipment below 1800C.

 

 

2, zirconia hollow ball brick, is an ultra-high temperature energy-saving lightweight special refractory material that can be used at 1800-2400 °C. Since the thermal conductivity of the insulating brick is 0.3-0.4W/(m·k)-1, not only the insulating lining material but also the direct working can be done on various ultra-high temperature electric furnaces, aluminum wire furnaces and tungsten rod furnaces. Layer lining material.

Due to the relatively pure raw materials, the commonly used refractory brick products are mostly in the range of high-grade products having a bulk density of less than 0.6 g/cm3. The refractory brick has the advantages of light weight, high compressive strength, low thermal conductivity, small volume shrinkage ratio, good thermal shock resistance, and can be used for the thermal insulation layer of high temperature thermal equipment or the furnace and precision directly interacting with the flame. The working lining of thermal equipment, but not suitable for direct contact with the erosion of molten and slag. It also has higher stability when used under a reducing atmosphere. The temperature of use depends on the purity of the refractory brick products, generally up to 1600 ~ 1800 ° C.

 

Alumina insulation articles can be used as a working layer for direct contact with a flame or as a thermal barrier. Widely used in ceramics, refractory firing kiln, powder metallurgy sintering furnace, semiconductor component firing kiln, furnace with hydrogen and reducing atmosphere, etc.

 

The above is the introduction of high-grade insulation bricks for Sunrise refractory materials. High-grade products can be used in places where ordinary products can not be used. The price is much more expensive than ordinary thermal insulation products. If you have other questions, please come to consult.
