Lightweight mullite insulation brick JM23 JM26 JM28 JM30
Mullite insulation brick is a kind of high-quality high-temperature-resistant insulation material with light weight, low thermal conductivity, heat insulation and high compressive strength for high-temperature furnaces. Mullite insulation bricks are mainly used for hot blast stove top, blast furnace chimney and bottom, glass melting furnace regenerator, ceramic high temperature furnace lining, etc.
Mullite insulation bricks use mullite as the main crystal phase, and the alumina content is about 65~75%. Mullite insulation bricks have high refractoriness, up to 1790°C. Its apparent initial softening temperature is about 1600-1700°C. Its cold compressive strength is about 70~260MPa.
Mullite insulation bricks are divided into 1350 mullite insulation bricks, 1450 mullite insulation bricks and 1550 mullite insulation bricks according to different operating temperatures. Quality mullite bricks.
