Good Erosion Resistance GM 1550 Silicon Mullite Refractory Bricks for Cement Kiln
Introduction:
Silicon mullite brick is a kind of refractory brick mainly composed of mullite, andalusite, silicon carbide and special grade homogenization alumina by high pressure shaping and high temperature firing.
Silicon mullite brick can be used at the bend and other special parts of tertiary air duct according to your requirement to efficiently resist the intense scouring of large amount of dust in tertiary air duct and erosion of chlor-alkali smoke-gas with the life span of more than three years.
