| High alumina mullite castables | |
Latest high aluminum mullite materials and prefabricated parts were developed especially to meet annular cooler work conditions, the cooler fence precast slabs request the materials can work normally under high - low temperature cycle, and the product must have good thermal shock stability and corrosion resistance. Our castables can meet the ring annular cooler slaps and side wall requirements very well, under the dynamic work conditions, HD high alumina mullite precast slabs work life can be more than two years, high Alumina mullite casting materials and prefabricated parts employeed side wall can work more than three years.
