Magnesia Ramming Refractory Mass
The Magnesia Ramming Refractory Mass supplied by Gongyi Hongda Furnace Charge Co. Ltd is a basic refractory material formulated with a minimum of 84% MgO by weight. The composition also controls calcium oxide between 6% and 8% and contains approximately 6% ferric oxide. Service temperature is specified between 1850°C and 1950°C, making it suitable for high-temperature steel ladle linings and nickel-iron furnaces. After sintering at 1600°C for three hours the material achieves a compressive strength of 40-50 MPa.
The product is produced using superfine powder technology, which yields a uniform distribution of calcium ferrite phases and minimizes shrinkage during sintering. Such ultrafine particle size improves density development and erosion resistance, traits that are standard expectations for premium magnesia refractories. Typical bulk magnesia ramming masses are supplied in 20 tonne bulk bags or loose bulk for ship-load, with moisture content kept below 1% to preserve performance. The material’s high slag resistance and thermal shock stability align with industry norms for refractory linings operating above 1200°C.
Primary users include steel plants, nickel-iron smelters and foundries that require durable furnace linings and low heat loss. The supplier offers the mass in bulk quantities and can arrange packaging to suit container or bulk carrier shipment, but exact minimum order quantities must be confirmed directly. Buyers should request a recent chemical analysis report and compressive strength test results before finalising the contract.

Sourcing Magnesia Ramming Refractory Mass from Gongyi Hongda Furnace Charge Co. Ltd - China Import Guide
Before placing an order, importers should obtain a recent Certificate of Analysis that confirms the MgO, CaO and Fe2O3 percentages, as well as the compressive strength results from a representative batch. Because the supplier’s response rate is currently listed as zero, it is advisable to initiate contact through the official address in Gongyi and request a sample for on‑site testing. Verifying the harbour-tier status and asking for any ISO or industry-specific certifications will further reduce risk.
Typical lead times for bulk magnesia ramming mass range from four to six weeks after order confirmation, but the exact schedule should be negotiated with the supplier. Importers often use FOB or CIF terms at the nearest Chinese port; clarifying the preferred Incoterm early avoids unexpected freight charges. Payment is usually secured by an irrevocable letter of credit, although some buyers arrange a partial advance payment after the sample is approved.
Upon arrival, the shipment should be inspected for moisture content and any physical damage before unloading. A third‑party laboratory can verify the chemical composition and compressive strength against the supplied test report. Retaining the Certificate of Analysis, the material safety data sheet and the inspection certificate will satisfy most customs and quality‑control requirements for downstream furnace installation.
