High Alumina Mullite Refractory Castables and Precast Blocks

High Alumina Mullite Refractory Castables and Blocks 1. Good thermal shock stability 2. Corrosion resistance 3. ISO Approved. High alumina mullite Refractory castables  Latest high alumina-mullite materials and precast blocks are especially designed to service annular cooler. The cooler fence precast slabs are subjected to severe temperature fluctuation, and the product must have good thermal shock stability and corrosion resistance. These castables can meet the requirements of the ring annular cooler slaps and side wall. The service life of high alumina-mullite precast slabs can be more than two years. The high alumina-mullite casting materials and precast blocks for side walls can also work more than three years.
