AZS Fused Cast Refractories are the most widely used materials in glass melting furnaces, frit kilns and occasionally some foundry plants (skid rails of reheating furnace). They can be classified by their zirconia content, which basically defines their corrosion resistance, into 3 families: AZS 33, AZS36 and AZS41.

JK-AZS33

Shapes and sizes:there are great variety of formats and shapes which are available for different forming and special machine processes.

Application: mainly used for working ends, feeder channel, side walls, superstructures, crowns, sidewalls, tank bottoms, C-shaped brick and doghouse crown.etc.

JK- AZS36 

Shapes and sizes:This product is only available for straight brick. 

Application:mainly used for side walls of flame furnaces with embedded melter bottoms, for total security with average pulls and campaign lengths, and superstructures, front wall, back wall, top crown in glass melting furnace.

JK- AZS41 

Shapes and sizes: this product is available in a large size straight or approximate bricks and special formats and shapes whichare available for special machining processes. 

Application: Mainly used for sidewalls, doghouses, throat, bottom budding, Dam blocks, electric block corners.

Features:

•  Strong corrosion resistance 

• High thermal shock resistance

•  High refractoriness under load

•  Low permanent linear change on reheating

•  Only available for straight brick
