Castable Refractories
Zhengzhou Smien Refractories Co., Ltd. supplies an Aluminous Refractory Castable composed of Al2O3‑based aggregates and a calcium aluminate binder. The product is an unshaped refractory material designed for casting or gunning into furnace, kiln and boiler linings. It offers high refractoriness, high density and low porosity, providing good slag and corrosion resistance. Additional attributes include high strength, wear resistance, thermal shock stability and a long service life.
The company lists both low‑cement and conventional castable grades, which differ mainly in cement content and resulting compressive strength. Typical alumina content for similar aluminous castables ranges from 45 % to 70 %, giving a maximum service temperature of around 1800 °C. Typical compressive strength values lie between 30 MPa and 80 MPa after 24 h curing, and bulk density is usually 2.5‑3.0 g cm‑3 with porosity below 5 %. These industry‑standard figures align with the performance requirements of steel plants, cement rotary kilns and glass furnaces.
Buyers such as steel manufacturers, cement producers, glass makers and petrochemical refineries commonly purchase this castable for furnace linings and reactor interiors. The material is traded in metric‑ton bulk shipments, with packaging typically in bulk bags or open‑top containers. Prospective importers should confirm the minimum order quantity, preferred Incoterms and payment conditions directly with the supplier. Because the listing does not disclose lead time, the buyer is advised to request an estimated delivery schedule before placing an order.

Zhengzhou Smien Refractories Co., Ltd. is located at Zhongzhou Avenue, Guancheng District, Zhengzhou, Henan 450000, China. The supplier holds a harbor verification tier on the platform, indicating that basic company information has been validated. It specialises in the production and export of aluminous refractory castables for high‑temperature industrial applications.
The platform data shows a response rate of 0 % and no recorded average response time, meaning the supplier has not responded to recent inquiries. Importers should therefore initiate contact through the provided messaging channel and request quotations or technical data directly. The supplier’s profile does not list additional certifications or client references.
Castable refractories are unshaped refractory materials consisting of graded aggregates, powders, and binders suitable for casting or gunning into furnace, kiln, and boiler linings. Low cement castable and conventional castable grades are widely applied in steel plants, cement rotaries, glass furnaces, and petrochemical reactors. These industrial refractory products are traded globally in metric tons, with pricing influenced by alumina content, cement type, and delivery volume for export shipments.

Sourcing Castable Refractories from Zhengzhou Smien Refractories Co., Ltd. - China Import Guide
Before placing an order, the importer should obtain a current chemical analysis confirming the Al2O3 percentage and the exact binder composition. A mill test report that includes compressive strength, bulk density and porosity values will verify that the product meets the required performance criteria. Request any available certifications for slag resistance or thermal shock stability to ensure the material aligns with the intended furnace conditions.
The shipment is normally dispatched in metric‑ton bulk bags or open‑top containers, so the buyer must confirm the preferred loading port in China. Because the listing does not disclose a lead time, the importer should ask the supplier for an estimated production and dispatch schedule. Clarify the Incoterms - such as FOB Zhengzhou port or CIF destination - and agree on payment terms, commonly a T/T advance or L/C at sight, before finalising the contract.
Upon arrival, the buyer should arrange an independent third‑party inspection to verify dimensions, density and absence of cracks. Request the original mill test report, chemical analysis certificate and a compliance statement with relevant ASTM or ISO standards. Retaining these documents will facilitate customs clearance and provide a reference for any future warranty or performance claims.
