Andalusite-Mullite Brick With High Thermal Shock Resistance has high cold crushing strength,high refractoriness under load, high thermal stability,good creep resistance and thermal shock resistance,It is alternative product for high aluminum bricks, used in the professional of the key parts of the furnaces.
The production process of Andalusite-Mullite Brick With High Thermal Shock Resistance and multi-clinker clay bricks are similar.
The difference is that the proportion of clinker in the ingredients is higher, which can be as high as 90-95%.
The clinker needs to be sorted and sieved to remove iron before crushing, and the firing temperature Higher, such as Ⅰ, Ⅱ high alumina bricks are generally 1500～1600℃ when fired in tunnel kiln.
Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.
The use of bauxite clinker and combined clay fine grinding method can improve product quality.
