FIRE BRICKS
JAINCO’s Fire Bricks are the products made from different fractions of refractory grog, plastic fire clays and non-plastic clays of high purity. The different fractions of these raw materials are mixed in counter current mixers and pugged for fully homogeneous mixing. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in oil fired tunnel kiln at high temperatures of 13000 C. These bricks are manufactured as per IS:6 & IS:8 specifications.
 Special Characteristics:
• 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 upto 1450 0 C.
