The baffle brick is also called a fire block and a block brick， and is generally installed behind the burner of the regenerative heating furnace for supporting and reinforcing the Ceramic regenerator material. It can be used in combination with honeycombs in various regenerative combustion systems. It is used in the front end of the regenerator of a regenerative heating furnace. Its function is to protect the regenerator and prolong the service life of the regenerator. It can guarantee the best performance and service life of the regenerator during use. greatly reduce the steel mill'” s shutdown time and reduce.
Besides the production of high- aluminum，mullite. corundum mullite， fused corundum and other conventional baffle bricks， we are capable of producing excellent slag resistance, heat flush resistance chrome corundum mullite, zirconium corundum mullite baffle brick which can be used in harsh environments. Dimensions and construction can be produced according to user’ s specific requirements.
