Fused Cast AZS 41# Blocks
Zhengzhou Smien Refractories Co., Ltd. produces Fused Cast AZS 41# Blocks in Zhengzhou, Henan, China, delivering a refractory brick that incorporates approximately 41 % zirconia (ZrO₂) by weight. The electro‑fused AZS composition combines alumina, zirconia and silica, and the blocks are formed using a high‑temperature arc furnace that creates a dense eutectic crystal matrix. They are exported in metric‑ton quantities and fall under the standard industrial refractory export classifications. The supplier notes that the casting methods employed are PT, ZWS and WS, allowing for custom dimensions.
The AZS 41# grade contains the highest proportion of corundum‑baddeleyite eutectic crystals among the series, which translates into exceptional corrosion resistance in fast‑wear furnace zones. Typical industry figures give a compressive strength of about 130 MPa, a bulk density near 3.3 g/cm³ and a service temperature capability of roughly 1750 °C. These attributes make the blocks ideal for sidewalls, doghouses, throat and bottom‑budding areas of glass‑melting furnaces where rapid melt flow and high temperatures are common. Their thermal shock resistance and low alkali reactivity further extend furnace life in demanding environments.
Potential buyers such as float‑glass manufacturers, container‑glass producers and high‑temperature steel plants often require large‑size blocks and may request special shapes for specific furnace components. The listing does not disclose minimum order quantities, lead‑time estimates or payment terms, so interested parties should contact the supplier for detailed quotations. The harbour‑tier verification and the Zhengzhou address provide a reliable basis for further commercial negotiations.

Zhengzhou Smien Refractories Co., Ltd. operates from Zhongzhou Avenue in the Guancheng District of Zhengzhou, Henan Province, China, postal code 450000. The company carries a harbour‑tier verification, confirming that its core business details have been validated, although its platform response rate is shown as 0 % with no average response time recorded. It focuses on the production of high‑zirconia fused‑cast refractories, catering to glass‑melting and high‑temperature metal processes.
In addition to the AZS series, the supplier offers a range of custom‑shaped refractory components manufactured by three casting processes - PT, ZWS and WS - to meet specific furnace design needs. The listing does not include explicit MOQ, pricing or lead‑time data, so prospective buyers are encouraged to request a formal quotation. The verified location in Zhengzhou enables importers to conduct site‑level due diligence if required.
Fused cast AZS 41# blocks are premium-grade electro-fused Al2O3-ZrO2-SiO2 refractories containing approximately 41% ZrO2, offering the highest corundum-baddeleyite eutectic crystal content in the AZS series. These blocks deliver superior corrosion resistance against glass melt and are the preferred lining material for high-quality glass furnaces, float glass tanks, and container glass production lines. Sourced primarily from China and exported globally to glass manufacturers, AZS 41# blocks are sold by metric ton with custom dimensions available for specific furnace designs.

Sourcing Fused Cast AZS 41# Blocks from Zhengzhou Smien Refractories Co., Ltd. - China Import Guide
Importers should first obtain the material test certificate confirming the 41 % ZrO₂ content and the electro‑fused AZS composition. Verifying the harbour‑tier status and the Zhengzhou address adds confidence to the supplier’s credibility. Requesting a small sample for laboratory density and strength testing can further reduce procurement risk.
These blocks are generally shipped in bulk, either on open‑top containers or in large industrial bags, with buyers usually negotiating FOB or CIF terms. It is essential to confirm the expected loading port, any special handling instructions and the lead time directly with the supplier, as these details are not disclosed publicly. Common payment methods for such volumes include T/T and a confirmed L/C.
Upon receipt, arrange a third‑party inspection to check bulk density, compressive strength and thermal‑shock performance against the supplied certificates. Secure documentation such as the Material Safety Data Sheet, test reports and a conformity declaration before installation. Maintaining these records supports ongoing quality assurance and any future warranty claims.
