Product Description

High Alumina Brick Refractory Brick Fireclay Brick for Hot Blast Furnace
The Description:

Aluminum oxide (Al2O3) content is higher than 48% of aluminum silicate refractory products.

A neutral refractory with an alumina content of more than 48%. It is made of alumina or other raw materials with high alumina content by molding and calcination. High thermal stability, refractories above 1770ºC. Good slag resistance, used for laying the lining of electric steel furnace, glass furnace, cement rotary furnace, etc.

High load soft, low creep high aluminum brick

It is a high-grade refractory made of super grade bauxite, fused corundum and fused mullite as the main raw materials. The product has the advantages of low creep at high temperature, strong erosion resistance, good thermal shock stability, etc., suitable for large and medium-sized hot blast furnaces, it opens up the next successful road for the localization of high-quality and high-grade imported refractory materials required for new hot blast furnaces in China, and has been included in the national "Spark Plan" project.

The Feature:
A. The refractoriness of high refractoriness aluminum brick is higher than that of clay brick and semi-silicon brick, up to 1750~1790ºC, which is a high-grade refractory material. b, the load softening temperature because high aluminum products Al2O3 high, less impurity, the formation of less fusible glass, so the load softening temperature is higher than clay bricks, but because mullite crystallization does not form a network organization, so the load softening temperature is still not high silicon bricks. c, slag resistance high aluminum brick Al2O3 more, close to neutral refractory materials, can resist the erosion of acidic slag and alkaline slag, because it contains SiO2, so the ability of alkali slag is weaker than the ability of acid slag.
