High Alumina Bricks Manufacturing Process
High alumina bricks manufacturing process is similar to the fireclay bricks’. But different from the fire clay bricks, high alumina bricks adopt higher proportion of clinker that reach up 90~95%. Select out and sieve all the iron slag before crushing and firing the clinker in the high temperature that reach up 1500~1600 degree.
Rongsheng, a China High Alumina Refractory Supplier, proves that in order to improve the high alumina brick products’ quality, it is necessary to sieve and store strictly the high alumina clinker in grades and then fine grind the bauxite clinker and binding clay together.
High Alumina Bricks Raw Materials
