Product Description

Lightweight Insulating Fire bricks
(1300ºC-1700ºC WH, WA and B, C Series)

Product Description
WH and WA Series of Lightweight Insulating fire bricks using ASTM standard, compared with general firebrick, it's light weight, internal distribution have tiny closed porosity, high porosity. Therefore, less heat loss, energy saving; at the same time accumulation amount is smaller, so the heating and cooling faster, suitble for rapid periodic use. The series of products applicable to 900~1700ºC temperature range.
Series of Firebrick for B, C products are in accordance with JIS Industrial Standard of JAPAN, the products are lightweight, low iron content, low reheat shrinkage and atmosphere corrosion resistance nd other excellent features. The series of products applicable to 900~1350ºC temperature range.
 

Product Features
Low thermal conductivity, good insulation
Low thermal capacity, elevating temperature fast
Low content of impurities, good performance under reducing atmosphere
High strength, resistance to thermal shock
High dimensional precision
Can be processed into special shape to reduce the number of brick and joint


Typical Applications
Various industrial furnace hot face refractoriness and back lining heat insulation layer
The melting furnace, burning kiln, the flue
Producer gas generator and pipeline, refining device
Heating device, annealing furnace, the soaking furnace
Reducing atmosphere furnace
