The Fire bricks we deal in are the refractory ceramic materials. These are used for kilns, fireboxes, lining furnaces, and fireplaces. The said bricks have been built mainly to endure high temperature. The bricks have a low thermal conductivity as well as greater energy efficiency. Fire bricks are suited for the applications with extreme chemical, mechanical and thermal strains. The bricks offered by Kundan Refractories can deal with elevated temperatures. In any case, these should not spall. They can retain the strength to a significant level and the bricks must have capacity to work efficiently according to the rapid temperature changes.
