Refractory High Alumina Bricks
Zhengzhou Smien Refractories Co., Ltd. manufactures refractory high alumina bricks in China for extreme‑temperature processes. The bricks are composed of high alumina material containing 55‑90 % Al₂O₃ together with bauxite chamotte, a composition that provides excellent hardness and chemical stability. They are intended for use in steelmaking furnaces, cement rotary kilns, glass melting tanks and other high‑heat industrial equipment.
Typical high‑alumina bricks exhibit compressive strengths of 70‑120 MPa and thermal conductivities of 1.0‑1.3 W/m·K, which enable them to withstand temperatures above 1 700 °C while maintaining structural integrity. Standard dimensions are 229 mm × 114 mm × 76 mm, with an approximate weight of 12 kg per unit, fitting the geometry of most furnace linings. Porosity is usually below 4 % and bulk density ranges from 2.3‑2.5 t/m³, characteristics that reduce heat loss and improve service life.
Buyers such as steel producers, cement manufacturers and glass factories often specify these bricks for their superior thermal shock resistance and load‑bearing capacity. Zhengzhou Smien notes that minimum order quantities are not disclosed, and shipping terms are not detailed, so buyers should confirm FOB or CIF conditions directly. The product is supplied in bulk palletized loads for container transport, and prospective customers are encouraged to request the supplier’s test reports and any available certification documents before finalising the purchase.

Sourcing Refractory High Alumina Bricks from Zhengzhou Smien Refractories Co., Ltd. - China Import Guide
Before committing to a purchase, confirm the exact Al₂O₃ percentage and request a mill test certificate that details compressive strength, thermal conductivity and porosity. Verify that the standard brick dimensions align with the geometry of your furnace or kiln, and ask for any available ISO or CE documentation to substantiate quality claims.
Logistics for Chinese‑origin bricks typically involve container shipping from the port of Shanghai or Tianjin. As the listing does not state specific Incoterms, lead‑time or payment conditions, buyers should negotiate FOB, CIF or other terms directly with Zhengzhou Smien and agree on a realistic delivery schedule.
Upon arrival, arrange an independent inspection to measure dimensions, weight and compressive strength against the supplied specifications. Obtain the supplier’s test reports and material safety data sheet to complete customs clearance and ensure the bricks meet your project’s technical requirements. Proper documentation and inspection will protect against non‑conforming deliveries.
