2. Introduction: High aluminum roller hole brick is a kind of refractory brick designed for roller kiln, which is divided into single hole, double hole,three holes and other brick types. It is a special refractory brick for ceramic roller. High strength, good thermal shock stability, good transmission and long service life. The raw materials used in the products are mainly Calcined Bauxite, high-quality clay and additives, machine-made molding, high-temperature firing.
3. Application: roller kiln,the hole bricks used in roller kiln are divided into clay, high aluminum and mullite. The ceramic roller bar is inserted into the hole brick, so that the dislocation does not occur in the transmission process, which is convenient for transmission. The hole diameter of the hole brick is customized according to the diameter of the stick. There should be a gap between the two, but it is not easy to be too large, otherwise, the transmission of the stick is unstable. According to the specific requirements, the hole brick can be divided into single hole, double hole and three hole. At present, the high alumina and mullite bricks are widely used. Hole brick is a kind of refractory brick for special use, which is specially produced for the transmission of stick.
