The fused cast alumina block supplied by Zhengzhou Smien Refractories Co., Ltd. is manufactured from high‑purity aluminium oxide (Al2O3) combined with a controlled glass‑phase binder. The material resists corrosion at temperatures up to 1350 °C and exhibits a zero bubble rate when in contact with molten glass. Its dense microstructure is achieved by electric‑furnace melting and casting of alumina at approximately 2000 °C. The blocks are intended for sidewalls, cooling‑zone pavers and float canals in glass furnace linings.
Typical production grades include alpha‑alumina, beta‑alumina and mixed alpha‑beta compositions, each offering a similar thermal stability. In the refractory industry a standard fused cast block contains more than 99.5 % Al2O3 and 2 - 3 % glass phase (typical). Conventional specifications call for a bulk density of at least 3.2 g cm‑3 and porosity below 5 % (standard). Mechanical strength is usually measured above 30 MPa compressive load (typical) and thermal conductivity ranges between 1.5 and 2.0 W m‑1 K‑1 (typical).
Glass manufacturers, steel‑making plants and cement producers commonly purchase these blocks to line high‑temperature zones where molten material contact is unavoidable. Zhengzhou Smien ships the product in metric‑tonne batches, normally packed in steel‑framed crates to prevent breakage during handling. Buyers should confirm the accepted Incoterm, payment method and any required pre‑shipment inspection with the supplier. Because the listing does not disclose a minimum order quantity, the exact MOQ must be verified directly with the company.

The company is headquartered on Zhongzhou Avenue in the Guancheng District of Zhengzhou, Henan Province, China. It is listed with a harbor‑level trust tier, indicating a moderate level of verification, and its response metrics show a current response rate of 0 % and an average response time of 0 hours. Zhengzhou Smien Refractories Co., Ltd. focuses on the production of refractory materials for high‑temperature industrial processes. Its catalogue includes fused cast alumina blocks, AZS blocks and other specialised refractories.
The present listing highlights the company’s capability to produce fused cast alumina blocks using electric‑furnace melting and casting techniques. No specific information on annual capacity, certified quality management systems or export licences is provided, so interested buyers should request those documents directly. The supplier does not disclose pricing, lead time or minimum order quantity in the public data. Communication with the sales team is required to obtain detailed trade terms.
Fused cast alumina blocks are premium-grade refractory materials designed for glass furnace applications, offering superior corrosion resistance and thermal stability at extreme temperatures. These blocks are composed primarily of high-purity alumina (Al2O3) with controlled glass phase composition, manufactured through electric fusion and casting processes for dense, homogeneous microstructure. Widely imported and exported for steel, cement, and glass production facilities, they represent a critical wear-resistant lining component in high-temperature industrial environments.

Before placing an order, importers should verify Zhengzhou Smien’s corporate registration in Henan and request copies of any quality management certificates that the company holds. Ask for a recent mill test report that confirms the alumina purity and glass‑phase content of the fused cast block. A sample piece can be evaluated for bubble rate and dimensional tolerance prior to a full shipment. Confirm that the supplier can provide a factory‑issued compliance statement for the relevant refractory standards.
Logistics for the fused cast alumina block are typically arranged in bulk containers, with the product loaded in steel‑framed crates. Because the listing does not state a lead time, buyers should ask the supplier for an estimated production and dispatch schedule, which often ranges from two to six weeks for standard orders. Clarify the preferred Incoterm - such as FOB Zhengzhou or CIF Shanghai - and agree on payment terms, commonly a 30 % advance with the balance upon presentation of shipping documents. Ensure that any freight forwarder is experienced with heavy refractory cargo.
Quality assurance usually involves a third‑party inspection either at the factory or at the port of loading. Importers are advised to request a pre‑shipment inspection report covering dimensions, density and surface integrity. Required documentation includes the mill test report, material safety data sheet and a certificate of conformity to the specified refractory grade. Maintaining records of these documents simplifies customs clearance and future quality audits.
