Fused cast AZS33

Henan Sialon Technology Co., Ltd. produces the Fused cast AZS33 refractory block in China, targeting glass‑melting furnace applications. The block consists of an Al2O3‑ZrO2‑SiO2 matrix with roughly 33 % zirconia, derived from pure alumina powder and zircon sand that are melted and cast in an arc furnace. This manufacturing route minimises electrode contamination and yields a uniform micro‑structure that resists glass corrosion. The company ships the blocks on standard wooden pallets secured with steel strapping for bulk export.

Typical industry practice for AZS33 blocks includes a density around 2.60 g/cm³ and a compressive strength that exceeds 35 MPa, both of which satisfy the performance demands of furnace superstructure and sidewall components. Thermal conductivity is generally about 1.4 W/m·K, while porosity remains below 5 %, contributing to good thermal shock stability. The blocks are offered in a standard cubic dimension of 250 mm per side, with a tolerance of ±3 mm and an average weight of 28 kg each. These specifications align with common dimensions used in modular furnace installations.

Potential buyers are manufacturers of float and container glass, as well as steel and cement plant contractors seeking refractory components that can withstand harsh molten‑glass environments. Henan Sialon does not disclose minimum order quantities, lead times or pricing, so interested parties should request a detailed quotation. The supplier’s harbour‑level verification signals basic compliance, though the platform records a zero response rate, indicating that direct communication should be established early in the sourcing process. Confirm incoterms, payment conditions and any required certifications before finalising any purchase.

Henan Sialon Technology Co., Ltd. is situated in the Yulian Ceramic Industry Gathering Area, Henan 451200, China. The firm holds a harbour‑level verification, indicating it meets the platform’s minimum trust criteria, but its response rate is recorded as 0 % with no average response time, so buyers should verify communication channels directly. The listing highlights the company’s capability to produce fused‑cast AZS refractory blocks using a special arc furnace, a process that limits electrode pollution and enhances material purity. No further corporate history, employee numbers or client references are provided in the source data.

The company’s product focus is on AZS refractory blocks, particularly the AZS33 grade with a 33 % zirconia content. These blocks are marketed for glass furnace superstructure, sidewall and doghouse applications, and are shipped in bulk on wooden pallets. The supplier does not disclose additional services such as on‑site installation or after‑sales support, and no specific certifications are mentioned in the listing.
