The shaped bricks are SDNR CF conforming to IS-2042 for cold face insulation bricks.   Advantages : Its light weight has high porosity, low thermal conductivity, and nil shrinkage. Does not crumble while sawing or chipping. Transit breakages almost Nil. Does not react with gases. Resistant to both, hot and cold thermal shocks. It is 30 times more cooling than bricks and 45 times more effective than concrete in insulation value. Can be used in direct contact with flame without fire bricks up to 600 deg C.More economical than many of the available insulation bricks and comparable to calcium     Silicate based products.   Uses :  In furnace walls, kilns, chimneys, flues and buck stays, boilers in Thermal Power Stations, Cold Storage walls, hot gases beds in coke oven batteries of steel plants. Etc. https://www.sdnrefractories.co.in/fire-bricks.htm https://www.sdnrefractories.co.in/fire-bricks.htm Wed, 10 Apr 2024 00:00:00 +0530 We manufacture and export a wide range of Selected grades of SDNR 40% Fire brick for industrial applications. These Refractory fire bricks are made from premium quality fire clay and are widely used as refractory insulation to retain insistent temperature   Advantages : Low ferric as iron contents are below 2.5 %. Neutral in chemical nature. Highly resistant to thermal shocks. Eliminates carbon deposits. Prevents brick failure at high temperatures Increases life of brick lining to great extent Withstand high temperature up to 1450 0 C.   Uses : In furnace walls, kilns, chimneys, flues and buck stays, boilers in Thermal Power Stations, hot gases beds in coke oven batteries of steel plants.
