furnace refractory bricks for Corundum ceramic regenerative ball
It is applied for accumulated and releasing the heat in the regenerative type burner.
Product Description
The regenerative ball is also called the ball regenerator, which has the advantages of good thermal shock resistance, high heat storage capacity, high strength, easy cleaning, and can be reused without breaking.
Heat storage ball and is suitable for air separation equipment storage and iron and steel plant blast furnace and gas heating furnace as heat storage packing, through the air and gas awakened double preheating, the combustion temperature quickly reach the effect of rolling of billet heating.
