Product Characteristic
High Alumina Brick
Compared to clay bricks, high alumina bricks exhibit outstanding features such as high refractoriness and load softening temperature. With an increase in Al2O3 content, the slag resistance improves significantly. Specifically, high alumina bricks possess the following properties:
(1) Refractoriness
The refractoriness of high alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750-1790°C. Refractoriness is primarily influenced by the content and type of Al2O3, increasing with higher Al2O3 content.
(2) Load Softening Temperature
Due to the high Al2O3 content and low impurity level in high alumina products, forming fewer fusible glass phases, the load softening temperature is higher than that of clay bricks. However, the load softening temperature is still lower than that of silica bricks due to the lack of a reticulated structure in mullite crystals.
(3) Thermal Conductivity
High alumina bricks have better thermal conductivity than clay bricks. This is attributed to the lower amount of glass phase with low thermal conductivity in high alumina products and the increased quantity of mullite and corundum crystals with good thermal conductivity.
(4) Thermal Shock Stability
The thermal shock resistance of high alumina bricks falls between clay products and siliceous products. It undergoes only 3-5 cycles of water quenching at 850°C. This is mainly due to the higher thermal expansion of corundum compared to mullite, without phase transformation. Currently, improving the particle structure, reducing the content of fine powder, and increasing the critical particle size and particle distribution of the clinker can enhance the thermal shock stability of the product.
