Magnesia Brick
The product is a magnesia brick manufactured by Zhengzhou Rongsheng Kiln Refractory Company in China. It is composed of high purity magnesium oxide (MgO) refractory material designed for fire‑resistant applications. The bricks are supplied in the standard size of 228 mm × 114 mm × 76 mm and each brick weighs approximately 30 kg. They meet the basic refractory standards required for steelmaking furnace linings and converter walls.
Magnesia bricks typically contain MgO purity of 96 % or higher, delivering refractoriness up to 1800 °C and compressive strength exceeding 120 MPa at 1000 °C. Their density is around 3.2 g cm‑³ with porosity near 12 %, providing excellent slag resistance in basic environments. Standard industry packaging places twenty bricks in a wooden crate to protect the material during transport. The product’s performance aligns with the common specifications used in iron and steel, non‑ferrous metallurgy, glass furnace regenerators and lime or cement kilns.
Primary users include steel mills, ferroalloy producers, copper and nickel smelters, as well as glass manufacturers and cement plant operators. Importers should confirm the required brick dimensions, purity grade and packaging format before placing an order. Trade terms such as FOB or CIF, minimum order quantities and payment conditions must be agreed directly with the supplier, as these details are not disclosed in the listing.

Sourcing Magnesia Brick from Zhengzhou Rongsheng Kiln Refractory Company - China Import Guide
Before placing an order for magnesia bricks from Zhengzhou Rongsheng Kiln Refractory Company, verify the MgO purity, dimensional tolerances and the presence of a material test report. Request a recent certificate of analysis and, if possible, a sample batch for laboratory validation. Confirm that the packaging format (twenty bricks per wooden crate) matches your handling facilities and that any required export documentation complies with Chinese customs regulations.
Discuss logistics early, specifying whether you prefer FOB Zhengzhou port or CIF to your destination. Ask the supplier for an estimated lead time, noting that the current response rate is low and timelines may need confirmation. Payment terms are typically negotiated on a per‑order basis; common arrangements include a telegraphic transfer on a pro‑forma invoice followed by a letter of credit at sight. Ensure the agreed Incoterm is clearly recorded in the contract.
Plan for independent quality inspection prior to shipment, either through a third‑party agency or on‑site at the factory. Inspection points should include dimensional checks, MgO content verification and visual assessment for cracks or surface defects. Upon acceptance, request the full set of documents: test certificates, packing list, commercial invoice and a certificate of origin. Maintaining these records will facilitate customs clearance and future supplier performance evaluation.
