Honeycomb protective blocks are also named as baffle bricks and fire block, block brick. It is generally installed behind the burner of the regenerative heating furnace to support and reinforce the ceramic regenerator material. Our baffle bricks can be used with honeycombs in various regenerative combustion systems. They are used in the front end of the regenerator of regenerative heating furnaces. Their function is to protect the regenerator and prolong the service life of the regenerator. Therefore, high temperature resistance and thermal shock resistance are the primary factors in the selection of baffle bricks. The baffle brick produced by our company has the characteristics of good thermal shock resistance, high softening point, strong chemical corrosion resistance and good thermal shock resistance, which can ensure the best performance and service life of the regenerator during use. Significantly reduce steel mills’ downtime and reduce production costs. Dimensions and construction can be produced according to user’s drawing requirements.
