The Magnesia-Carbon Brick supplied by Sinometal Machinery Corp. is a refractory component designed for extreme temperatures in steelmaking processes. Each brick contains magnesium oxide between 80 % and 95 %, carbon between 5 % and 20 % and a graphite binder, as stated in the supplier’s material specification. The bricks are routinely installed in basic oxygen furnaces, electric arc furnaces and ladle linings to resist slag erosion and thermal shock. Export shipments are packed on standard wooden pallets wrapped in polyethylene film for bulk handling.
In the broader refractory market, magnesia-carbon bricks typically exhibit a bulk density of 2.5‑3.0 g cm⁻³ and a compressive strength above 80 MPa, which aligns with the performance required in steel plants. The product conforms to national Chinese standards and the supplier’s own quality system, backed by ISO 9001 and ISO 14001 certifications. Typical dimensional tolerances are ±2 mm on a nominal size of 450 × 250 × 120 mm, allowing straightforward installation in furnace hearths. The low dilatability of the graphite‑rich matrix contributes to a refractoriness of roughly 1 800 °C, a value regarded as standard for this class of bricks.
Steel manufacturers, foundries and large‑scale importers purchase these bricks to maintain continuous operation of high‑temperature lines. Buyers should confirm the minimum order quantity, lead time and preferred Incoterms directly with Sinometal, as the listing does not disclose those details. Payment terms, inspection requirements and shipping documentation are also matters to settle before finalising a contract.

Before placing an order, importers should obtain the latest certificate of analysis confirming the MgO and carbon percentages, as well as the graphite binder content. Verify that the bricks meet the national Chinese refractory standard cited by the supplier and request copies of the ISO 9001 and ISO 14001 certificates. Asking for a sample batch can also help assess slag resistance and thermal‑shock performance.
Logistics planning must include confirmation of pallet dimensions, the number of bricks per container and the chosen Incoterm, whether FOB, CIF or another term. Discuss with the supplier the expected lead time, as it is not published, and negotiate payment conditions such as a letter of credit or advance payment. Ensure that shipping documents list the correct HS code and country of origin for customs clearance.
Quality assurance can be reinforced by arranging a third‑party inspection at the factory before loading, focusing on dimensional tolerances and compressive‑strength testing. Request a mill test report and the supplier’s quality‑management records. Upon arrival, retain the packing list, certificate of origin and inspection certificate to support any warranty or claim procedures.
