Zhengzhou Smien Refractories Co., Ltd. manufactures Fused Cast AZS 36# Blocks in Zhengzhou, Henan, China, offering a refractory brick that contains approximately 36 % zirconia (ZrO₂) by weight. The blocks are produced by fused‑cast technology using a special arc furnace, resulting in a dense eutectic crystal structure of alumina‑zirconia‑silicon. They are supplied in metric‑ton bulk shipments and classified under standard industrial refractory export categories. The material composition and casting methods (PT, ZWS, WS) are specified by the supplier.
The presence of free baddeleyite crystals in a chain structure and a reduced vitreous phase give the AZS 36# blocks superior erosion and corrosion resistance compared with lower‑zirconia grades. Typical industry data show a compressive strength around 120 MPa, bulk density near 3.2 g/cm³, and a maximum service temperature of about 1700 °C. These properties make the blocks suitable for high‑temperature glass‑melting environments where melt flow is rapid and temperatures are elevated. Their thermal shock stability and resistance to alkali attack further extend service life in demanding furnace sidewalls, doghouses and paving zones.
Buyers such as glass manufacturers, steel producers and petrochemical plants typically request bulk packaging and may negotiate FOB or CIF terms per shipment. Since the listing does not disclose minimum order quantities, lead times or payment conditions, interested importers should contact the supplier for exact details. The supplier’s harbour‑tier verification and address in Zhengzhou provide a clear point of reference for due‑diligence.

Before placing an order, importers should request the material test certificate that confirms the 36 % ZrO₂ content and the fused‑cast composition. Verifying the supplier’s harbour‑tier status and cross‑checking the registered address in Zhengzhou helps establish credibility. If possible, arrange a pre‑shipment sample to assess density and surface quality.
The blocks are normally shipped in bulk, either on open‑top containers or in large bags, and buyers commonly negotiate FOB or CIF terms. Confirm the expected lead time, loading port and any special handling requirements with the supplier, as these details are not disclosed in the public listing. Payment methods such as T/T or a confirmed L/C are typical for bulk refractory transactions.
Upon receipt, a third‑party inspection can verify bulk density, compressive strength and thermal‑shock resistance against the supplied test reports. Documentation such as the Material Safety Data Sheet, test certificates and a conformity declaration should be obtained before the blocks are installed in the furnace. Maintaining these records supports quality assurance and future warranty claims.
