Fused cast refractories are refractory materials made by melting high-purity raw materials in an electric arc furnace, directly casting them into a mold, and slowly cooling them in an annealing lehr. Unlike conventional sintered refractory bricks, these refractory materials have a denser structure, resulting in greater resistance to chemical attack and a longer service life.
Common Fused Ccast Refractory Products
Fused Cast AZS Brick
- Type: AZS 33#, AZS36#, AZS41#;
- Advantage: AZS has a mature melting and casting process and is used in glass furnaces worldwide, resulting in high market demand and a standardized process;
- Application: Widely used in the glass industry, different grades are suitable for different working conditions. Commonly used in glass furnace regenerators, flues, throats and bottoms.
Fused Cast Alumina Brick
- Advantages: High Al₂O₃ content, high temperature resistance (>1800°C), and excellent slag resistance. It barely reacts with most molten slags at high temperatures, making it a general-purpose high-temperature refractory brick;
- Applications: Furnace roofs and linings in the metallurgical, steel, and non-ferrous alloy industries, as well as regenerators in glass kilns.
Fused Cast Magnesia and Spinel Brick
- Features: Mainly composed of MgO·Al₂O₃, it combines the advantages of both fused magnesia bricks and fused alumina bricks. It offers strong resistance to alkaline slag and better thermal shock resistance than single-component bricks. Furthermore, it has high thermal conductivity and is resistant to rapid cooling and heating.
- Applications: Steel industry (converters, electric furnaces, refining furnaces), cement kiln transition zones, and high-temperature zones.
Who May Need Fused Cast Refractories?
- Glass factories: Concerned about glass erosion, stone formation, and streaking affecting glass quality, they desire longer furnace life.
- Steel/Nonferrous industries: Concerned about metal and slag erosion of the furnace lining, they require slag resistance and thermal shock stability.
- EPC engineering companies: Require a complete furnace solution with guaranteed supply and installation support.
- Distributors/Agents: Looking for a stable supply of standard models with market support documentation.
