Lightweight Insulating Refractory Bricks and Matching Cement

Product Description
Hongyi lightweight heat-insulating refractory bricks adopt ASTM standards. Compared with general refractory bricks, they are light in weight, with evenly distributed tiny closed pores inside and high porosity, so there is less heat loss and more energy saving; at the same time, the heat storage capacity is smaller, so the heating and cooling are faster, suitable for rapid periodic use.
This series of products is suitable for a temperature range of 900℃ to 1700℃. Hongyi lightweight heat-insulating refractory bricks adopt 1S Japanese industrial standards. The product has excellent characteristics such as light weight, low iron content, low weight shrinkage and resistance to atmosphere erosion. This series of products is suitable for a temperature range of 900℃ to 1350℃.
