The product is a magnesia carbon brick produced by Zhengzhou Sunrise Refractory Co., Ltd. in China. It consists of a composite of magnesium oxide (MgO) and carbon, designed for use in primary steelmaking environments. Typical formulations contain more than 70 % MgO and carbon levels between 10 % and 20 %. The bricks can be supplied in standard dimensions of 228 mm × 114 mm × 76 mm, with a weight of about 28 kg each.
Magnesia‑carbon composites are valued for their superior slag resistance and thermal shock stability, allowing service temperatures up to 1700 °C. Their thermal conductivity, usually around 0.8 W m‑¹ K‑¹, helps distribute heat evenly in basic oxygen and electric arc furnaces. Standard density for this type of brick is approximately 2.8 g cm‑³, and compressive strength typically exceeds 100 MPa at 1000 °C. These characteristics align with the requirements of steel, cement and foundry plants that demand durable refractory linings.
Key buyers include integrated steel mills, cement manufacturers and foundries that operate high‑temperature kilns. Importers should confirm the exact brick size, carbon content range and packaging configuration before ordering. Commercial conditions such as minimum order quantity, FOB or CIF terms and payment method must be negotiated directly with the supplier, as they are not disclosed in the public listing.

Before confirming a purchase of magnesia carbon bricks from Zhengzhou Sunrise Refractory Co., Ltd., verify the MgO and carbon percentages, dimensional tolerances and the existence of a material test report. Request a recent certificate of analysis and, if possible, a sample for laboratory assessment. Ensure that the packaging format (palletised bricks) aligns with your warehouse handling capabilities and that any required export licences are prepared in accordance with Chinese regulations.
Clarify the preferred Incoterm, such as FOB Zhengzhou port or CIF to your destination, and ask the supplier for an estimated production lead time, keeping in mind the low response rate noted in the profile. Typical payment arrangements include a telegraphic transfer against a pro‑forma invoice or a sight letter of credit; negotiate the terms that best match your risk management policy. Record the agreed Incoterm and payment schedule in the purchase contract to avoid misunderstandings.
Arrange for an independent third‑party inspection before shipment, focusing on dimensional accuracy, carbon content verification and visual inspection for cracks or surface defects. Upon satisfactory inspection, request the full documentation package: test certificates, packing list, commercial invoice and certificate of origin. Maintaining these records will smooth customs clearance and provide a reference point for future quality assessments of the supplier.
