Product Introduction
Fire-resistant and acid-resistant bricks are the main refractory materials used in acid regeneration roasting furnaces such as cold-rolled sheets and silicon steel wires in the steel-making system. Their performance directly affect the service life and economic benefits of the acid regeneration furnace.
Features
1. Anti-corrosion by acids, alkalis, oxidants and solvents.
2. Good resistance to mechanical and physical shocks.
3. Cost-efficient.
Application
Fire-resistant and acid-resistant bricks are mainly used in acid regeneration roasting furnaces ,coke oven, and other kilns for smelting industry.
