Product Description of Premium Blast Furnace Alumina Carbon Brick With Unmatched Durability And Thermal Shock Resistance
The lower section of the furnace body operates at higher temperatures and is a region with intense heat exchange. In this area, a significant amount of low-melting substances forms, and the furnace faces abrasion from the descending hot charge, erosion caused by dust as the gas rises, and corrosion from alkali metal vapors. Consequently, this part of the furnace is particularly vulnerable to wear and damage. In extreme cases, the entire cooler may be eroded, leaving only the steel shell to provide support. Therefore, it is crucial to use blast furnace alumina carbon bricks that offer exceptional resistance to slag, alkali, high-temperature strength, and superior wear resistance
Alumina Carbon Bricks Features
