Magnesia Chrome Bricks
The offering is a magnesia‑chrome brick described as a MgO + Cr₂O₃ composite where periclase and spinel constitute the primary mineral phases. Although the supplier does not publish exact chemical percentages, the material is marketed for its high refractoriness and resistance to both alkaline and certain acidic slags. The product is supplied in the standard fire‑clay brick size commonly used in the industry, and the description notes that it is a frequently traded commodity in global refractory markets.
In practice, magnesia‑chrome bricks of this class typically contain 70‑80 % MgO and 8‑12 % Cr₂O₃, with the remaining balance made up of spinel, SiO₂ and minor oxides. Standard industry specifications call for a bulk density around 2.9‑3.0 g/cm³, porosity near 18 %, and a cold compressive strength in the range of 35‑45 MPa. Dimensional tolerance is usually ±2 mm for the 229 mm × 114 mm × 76 mm module, and thermal expansion is about 1.5 % measured at 1400 °C, which aligns with the performance expectations for alkaline refractory linings.
Typical buyers are steel‑making plants, cement rotary kiln operators and non‑ferrous metal smelters that require a lining capable of withstanding high‑temperature thermal shock and slag corrosion. Importers usually request custom grades to match specific furnace designs, and they negotiate trade terms such as FOB or CIF from Chinese ports. The supplier indicates that the bricks can be supplied in standard dimensions with the option for custom specifications, so purchasers should confirm minimum order quantities and any special packaging requirements before finalising the contract.

Sourcing Magnesia Chrome Bricks from Zhengzhou Huachen Refractory Co., Ltd. - China Import Guide
Importers should first obtain a mill test report that confirms the chemical composition, bulk density and compressive‑strength values for the specific grade being purchased. Requesting copies of any third‑party inspection certificates will help ensure the bricks meet the required standards before shipment.
Logistical arrangements for Chinese refractory exports usually involve FOB or CIF terms from ports such as Shanghai or Tianjin. Typical lead times range from four to six weeks after order confirmation, but exact timing should be agreed with the supplier. Payment is often made by T/T in advance or via an irrevocable L/C, with milestones aligned to production and loading stages.
Upon arrival, buyers are advised to conduct a visual check for cracks, verify dimensions against the 229 mm × 114 mm × 76 mm standard and perform a random compressive‑strength test in accordance with ASTM C‑1314. Arranging an independent inspection agency to confirm compliance with the supplied specifications and to collect the full documentation set - mill test certificate, packing list and certificate of origin - will minimise the risk of non‑conforming material.
