Product Description

Low Apparent Firecaly Refractory Brick Unshaped Brick for Glass Furnace
The Description:
Clay bricks with refractory clay or burnt gem clinker as the main raw material, containing 30% ~ 46% alumina, refractoriness 1580 ~ 1770ºC, is a weak acid refractory material, good thermal vibration resistance, corrosion resistance to acid slag, widely used, clay bricks with refractory clay as the main raw material is called ordinary clay bricks, made of burnt gem clinker as the main raw material. Clay bricks with apparent porosity below 17% are called low-porosity clay bricks.

Characteristics of low porosity clay brick:
High load softening temperature, excellent thermal shock resistance, good volume stability, low porosity, good mechanical strength, good wear resistance, permeability resistance, acid resistance and slag corrosion resistance.

Application:
Low porosity clay brick is widely used in large blast furnace matching hot blast furnace, mainly used in the middle and lower cell of hot blast furnace regenerator, support arch and so on. In addition, lime kiln high temperature belt, glass kiln regenerator and other high temperature industrial kilns.
