Baffle bricks

Baffle bricks are generally installed in the burner combustion system of regenerative reheating furnaces. Their function is to protect the regenerator and heat storage balls and extend the service life of the regenerators and heat storage balls. Therefore, high temperature resistance and thermal shock performance are the primary factors for selecting baffle bricks. The baffle  bricks developed by our company are machine-pressed or poured and vibrated, and are fired at high temperature. They are resistant to peeling, erosion, cracking, and cracking. It has the advantages of not being easily deformed at high temperatures. This product has been used on more than 200 regenerative burners of reheating furnaces in more than 40 units such as Jiuquan Iron and Steel Co., Ltd., Weishan Iron and Steel Co., Ltd., Lianyuan Iron and Steel Co., Ltd., and has been well received by users.

Regenerative Ceramic Honeycomb

Our company uses zirconium corundum, mullite, andalusite, kaolin, etc. as the main raw materials to develop the zirconium corundum mullite honeycomb , which has a low high-temperature reburning linear change rate and a small linear shrinkage rate at high temperatures. It can prevent the honeycomb from sinking and dislocating during long-term use, effectively avoids short circuit of heat exchange gas, and has good high-temperature volume stability. The introduced ZrO improves the anti-erosion and penetration performance of the honeycomb and enhances the dust resistance bonding ability of the honeycomb. It can reduce the generation of low-melting liquid phase and increases the service life of the honeycomb.
