Product Name: Insulating Fire Brick for Hot Face Lining (JM28) Model NO.: JM28 Shape: Brick Type: Refractory Material Feature: Long Time Materials Refractoriness (?): 1580< Refractoriness< 1770 Al2O3: More Than 45 Trademark: CMAX Transport Package: Carton+Pallet or Pallet Specification: ASTM Standard Origin: China HS Code: 69022000 Product Description As the supplier of OSRAM (USA) for refractories, CNBM hopes to share our experience with you!GENERAL INFORMATION:CMAX insulating firebricks are classified under temperature between 1300º C and 1700º C, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulationCMAX insulating firebrick can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non ferrous foundries, petrochemical, ceramic, glass, cement and oil fired electric power generating plants.ADVANTAGES:Light weight and low thermal conductivity allows thinner furnace wallsMaintain stable structural strength throughout ambient to maximum service temperatureLow heat storage results in rapid cooling and heating operationLow iron and impurities to enhance reducing atmosphereHigh thermal shock resistance in preventing spallingNon standard sizes and shapes are available upon requestAPPLICATIONS:Ceramic shuttle kilnsmetal heat treatment furnaces Steel billet reheating furnaces Oil refinery heatersLaboratory furnaces
