(1) Insulating mullite bricks, which have the characteristics of uniform expansion, excellent thermal shock stability, high load softening point, low temperature creep value, high hardness and good chemical corrosion resistance. Insulating mullite bricks are mainly classified into light and heavy depending on the density. According to the different operating temperatures, types: MG-23, MG-25, MG-26, MG-27, MG-28, MG-30, and MG-32 series.
(2)Insulating mullite bricks, one of the most important members of thermal insulation bricks, can directly contact the flame (very important feature), with high temperature resistance, light high, low thermal conductivity and remarkable energy saving effect. It is suitable for the lining of cracking furnace, hot blast stove, ceramic roller kiln, electric porcelain drawer kiln, glass crucible and various electric furnaces.
