The Refractory Materials For Glass Industry

Big Sized Casting Fireclay Block

1. Brief description

Using big vibrating table and adopting special castables, the company produces furnace large fireclay blocks with vibrate moulding technology. The physical and chemical properties and appearance of the blocks have exceeded the national standards. The resistant ability to molten glass of the products is better than that of fanditional casting process products and ramming products. The products are especially suitable to build the bottom of furnace, cooling and working end side wall of glass furnace.

2. Features

1. Move Cast shaped

2. Excellent corrosion resistant of glass liquid.

3. Can resist high temperature

3. Applications

Used for glass furnace bottom and wall and so on

Zircon Corundum Brick

Fused Casting Zirconia Corundum (AZS) bricks for glass furnace 
1) Sintered technique.
2) For glass furnace
3) ISO9001

Definition:
It is mainly made of the baddeleyite and corundum material.
Raw material:
corundum and baddeleyite eutecticum
Product technology:
Casting technology.
Production process:
Made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material,
melting in the electric furnace, casting, annealing, machining, then finished.

Highlight:
1). Fine thermal conductivity in the normal temperature.
2).Compact structure
3).Strong resistant erosion stability to the glass liquid.
4).Not color to the glass.
