Tank bottom big fireclay block
Big fireclay block is one of the main varieties of aluminum silicate products. It is with vibrate moulding technology,made of clay clinker as aggregate and refractory clay as binder. Have high corrosion and pollution resistance against the molten glass.The products are especially suitable to build the bottom of furnace, cooling and working end side wall of glass furnace.
Scope of application
• It is widely used in glass melting tank bottom, wall, cooling section etc.
Advantage
• Good resistance corrosion against alkali and glass solution
• High density,reduce glass defects and improve glass quality
• Good thermal shock resistance
• Excellent volume stability at high temperatures
• Long using life
