Product Description

Product Description
WH and WA series of Lightweight Insulating Fire bricks using ASTM standard,Compared with general firebrick, Its 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, Suitable for rapid periodic use, The series of products applicable to 900 ~ 1700 ºC temperature range.
series of Firebrick for B,C Products, are in accordance with JIS Industrial Standard of JAPAN,. Products are lightweight, low iron content, low reheat shrinkage and atmosphere corrosion resistance and other excellent features. The series of products applicable to 900 ~ 1350 ºC temperature range
