Export high quality fused cast AZS bricks
Export quality fused cast AZS bricks from Zhengzhou Huachen Refractory Co., Ltd. are manufactured using electric fusion of high-purity alumina, zirconia, and silica, resulting in dense, non-porous blocks with three standard grades: AZS-33, AZS-36, and AZS-41, corresponding to 33%, 36%, and 41% zirconia content by weight. These bricks are designed for glass melting furnace linings where thermal shock resistance and chemical inertness are critical, operating continuously at temperatures up to 1800°C. The material composition minimizes glass contamination and bubble formation during operation.
The AZS-33 grade is suitable for general furnace zones with moderate glass flow, offering good resistance to molten glass corrosion without excessive cost. The AZS-36 grade, with a higher concentration of free baddeleyite crystals and reduced vitreous phase, is typically installed in high-temperature areas such as melter sidewalls and paving, where erosion rates are accelerated. The AZS-41 grade contains the highest density of evenly distributed baddeleyite crystals, delivering the strongest corrosion resistance and is reserved for the most aggressive zones like the doghouse and overflow channels. All grades are cast to near-net shape with controlled cooling to reduce internal stresses.
These bricks are primarily purchased by glass manufacturers in Europe, North America, and Southeast Asia for flat glass, container glass, and specialty glass production. Packaging is standardized in wooden crates with moisture-proof lining, and export shipments typically use FOB Qingdao or CIF terms. Minimum order quantities are not stated in the listing but are commonly negotiated based on furnace size and production schedule. Buyers should confirm dimensional tolerances and batch traceability before placing orders.
| Material Composition | Fused cast Al2O3-ZrO2-SiO2 (AZS), with zirconia content of 33%, 36%, or 41% by weight |
| Density | Typical density range of 3.6 to 3.9 g/cm³, depending on grade and cooling rate |
| Apparent Porosity | Less than 1.5% for all grades, indicating high fusion completeness |
| Cold Crushing Strength | Typical range of 80 to 120 MPa, with AZS-41 achieving the highest values |
| Thermal Expansion Coefficient | Typical value of 5.2 to 5.8 x 10^-6 /°C at 25 - 1000°C |
| Maximum Service Temperature | 1800°C, with continuous operation recommended below 1750°C |
| Grain Structure | Zirconia-rich baddeleyite crystals dispersed in a glassy matrix, with crystal size varying by grade |
| Standard Dimensions | Typical block sizes: 230 x 114 x 65 mm, 230 x 114 x 75 mm, or custom as per furnace design |
| Tolerance | Typical dimensional tolerance ±1.0 mm on length and width, ±0.5 mm on thickness |
| Packaging | Wooden crates with inner plastic wrap, moisture barrier, and labeled per batch number |
Zhengzhou Huachen Refractory Co., Ltd. is a manufacturer based in Zhengzhou, Henan Province, China, with a physical address listed on industrial zoning records. The company operates a production facility focused on fused cast refractories for the glass industry, with no public information on workforce size, annual output, or client list. The supplier is verified as a harbor-tier entity, indicating basic compliance with export documentation standards, but has no recorded response rate or average response time, suggesting limited buyer communication infrastructure.
The listing confirms the company produces fused AZS bricks in three grades and describes their application zones within glass furnaces, but provides no details on R&D capacity, laboratory testing equipment, or third-party certifications. There is no mention of ISO standards, environmental compliance, or export experience beyond the product description. Buyers should treat this supplier as a direct manufacturer with limited public transparency and verify all technical claims independently before procurement.
Fused cast AZS bricks are premium refractory blocks manufactured from high-purity alumina, zirconia, and silica via electric fusion and casting, available in AZS-33, AZS-36, and AZS-41 grades denoting zirconia content. These blocks are engineered for glass melting furnaces and glass tank linings, offering superior corrosion resistance, thermal shock stability, and high-temperature structural integrity at up to 1800 degrees C. Widely exported for glass production facilities worldwide, AZS fused cast blocks meet international refractory standards and are available in standard and custom dimensions with export-grade packaging.

Sourcing Export quality fused cast AZS bricks from Zhengzhou Huachen Refractory Co., Ltd. - China Import Guide
Before ordering AZS bricks from Zhengzhou Huachen Refractory Co., Ltd., verify the exact grade and batch number against your furnace design requirements. Request a copy of the chemical analysis report for zirconia, alumina, and silica content, and confirm the apparent porosity and cold crushing strength meet your furnace’s operational limits. Ensure the supplier can provide traceability from raw material to final product, as contamination risks are high in glass manufacturing environments.
Confirm the Incoterms, packaging, and lead time directly with the supplier, as these are not stated in the listing. Typical lead times range from 4 to 8 weeks depending on order volume and furnace scheduling. Payment terms are usually 30% advance, 70% against copy of bill of lading. Export packaging must include moisture barriers and labeling per batch. Verify whether the supplier handles export documentation or if you must arrange customs clearance independently.
Perform a pre-shipment inspection to check for surface cracks, dimensional deviations, and packaging integrity. Use a portable density tester or water immersion test on sample bricks to verify porosity. Request that the supplier provide a certificate of conformity with test results for each batch. Retain a sample from each shipment for future quality audits, as variations between batches can affect furnace performance and glass clarity.
