R.r. Fire Bricks

We are engaged in manufacturing and supplying of Fire Bricks in Cuddalore, Tamil Nadu, India. Firebrick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high heat, but should also usually have a low thermal conductivity to save energy. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from wood, fluxing from ash or slag, and high temperatures.
Fireclay is baked in the kiln until it is partly vitrified, and for special purposes may also be glazed. Fire bricks usually contain 30-40% aluminium oxide or alumina and 50% silicon dioxide or silica.
