Product description:
WH and WA series lightweight insulating refractory bricks adopt ASTM standards. Compared with ordinary refractory bricks, they are light in weight, evenly distributed with small closed pores inside, and have high porosity. Therefore, they have less heat loss and more energy saving; At the same time, the heat storage is smaller, so the heating and cooling are faster, which is suitable for rapid periodic use. This series of products are applicable to the temperature range of 900℃~1700℃.
WH B and C series light heat insulation refractory bricks adopt JIS Japanese industrial standard. The product has the excellent characteristics of light weight, low iron content, low heavy burning shrinkage and resistance to atmospheric erosion. This series of products are applicable to the temperature range of 900℃~1350℃.
Product features:
◇ Low thermal conductivity, good heat insulation
◇ High strength, good thermal shock resistance
◇ Low heat capacity, fast temperature rise and fall
◇ High dimensional accuracy
◇ Low impurity content, good performance in reducing atmosphere
◇ It can be processed into a special shape to reduce the number of bricks and joints
Typical application:
◇ Various industrial furnace hot surface refractory materials and backing insulation layer
◇ Heating device, annealing furnace, soaking furnace
◇ Melting furnace, firing kiln, flue
◇ Reducing atmosphere furnace
◇ Gas generator and pipeline, refining device
