Fused Cast AZS Block: Premium Refractory for Glass Furnace
1. Product Introduction
Fused cast AZS block is a high-grade electrofused refractory material specially developed for ultra-high temperature and strong corrosive industrial environments. It is produced by high-temperature electric arc melting and integral casting process, with compact structure, extremely low porosity and excellent chemical stability. Compared with traditional refractory bricks, AZS fused cast blocks show far better resistance to molten glass erosion and alkaline vapor corrosion, making them the core lining material for all kinds of glass furnaces.
We supply complete series of AZS blocks, including AZS-33, AZS-36 and AZS-41 according to different zirconia content. Various casting methods such as regular cast, oriented cast and void-free cast are available. Custom sizes and precision processing services can be provided to meet different furnace structure and working condition requirements.
2. Core Performance Characteristics
AZS fused cast blocks own comprehensive superior physical and chemical properties, which ensure long service life and stable operation of high-temperature furnaces.
-
Excellent Glass Corrosion Resistance: Resist long-term erosion and penetration of molten glass and alkaline steam, greatly reduce lining loss, and extend furnace service life.
-
Dense and Uniform Structure: Low apparent porosity and high bulk density effectively prevent molten medium penetration and improve overall structural stability.
-
Low Pollution & High Purity: Stable glass phase precipitation, few bubbles and stones during application, effectively guarantee the quality of finished glass products.
-
Superior Thermal Stability: Good thermal shock resistance and volume stability under repeated high temperature heating and cooling, avoiding cracking and peeling.
-
High Mechanical Strength: Excellent cold crushing strength and abrasion resistance, suitable for long-term continuous industrial operation.
3. Main Application Scope
Fused cast AZS blocks are professionally applied to all types of glass melting furnaces, widely used in float glass, container glass, fiberglass, photovoltaic glass, optical glass and special glass production industries.
Common application parts include furnace side wall, furnace bottom, throat, weir block, corner block, forehearth and key high-temperature corrosion-resistant areas. It is the most reliable lining material for large-scale, continuous and high-efficiency glass production lines.
4. Product Grade Classification
Our AZS fused cast blocks are classified strictly according to zirconia content and production process to adapt to different working temperature and corrosion intensity:
-
AZS-33: Suitable for conventional glass furnace parts with general corrosion resistance requirements, cost-effective.
-
AZS-36: Balanced performance grade, widely used in most mainstream glass furnace structural parts.
-
AZS-41: High zirconium content grade, with ultra-strong corrosion resistance, suitable for ultra-high temperature and severe corrosion key positions.
