The product is Silica Ramming Refractory, a high‑grade siliceous material supplied by Gongyi Hongda Furnace Charge Co. Ltd in China. It is made from quartzite, quartz sandstone and gangue with a silica purity of 95‑99 % as stated in the supplier data. The material is offered in bulk or big‑bag form for industrial procurement. This refractory is classified as an acid‑type lining material used in metallurgical and glass furnace environments.
The quartz‑rich composition provides excellent thermal stability and resistance to corrosion at temperatures up to 1650 °C, which matches typical industry performance for acid refractories. Standard industry practice expects a bulk density around 2.4 t/m³ and moisture content below 0.5 %, values that are typical for this grade. Suppliers often grade the product by particle size, with a common range of 0‑5 mm for ramming applications.
End users such as steel mills, coke oven operators and glass manufacturers source this material for furnace linings and crucible construction. Procurement is usually arranged on FOB or CIF terms from Chinese ports, with packaging in 20 kg bags or large bulk containers. Buyers should confirm the exact MOQ, shipping schedule and any required test certificates directly with the supplier. Payment is commonly made by T/T or L/C after the pro‑forma invoice is accepted.

Before placing an order, importers should verify the supplier’s current production capacity, confirm the exact silica purity and request a recent laboratory analysis report. Checking the validity of any provided test certificates and ensuring that the packaging meets handling requirements will reduce the risk of non‑conforming shipments.
Logistics for this product are typically organised on FOB or CIF terms from major Chinese ports. Buyers need to confirm the expected lead time, container loading plan and any special handling instructions for bulk refractory materials. Payment methods such as irrevocable L/C or T/T against inspection reports should be agreed in advance to protect both parties.
Quality assurance commonly includes a pre‑shipment inspection, verification of bulk density and moisture content, and a review of the MSDS and chemical composition certificate. Importers are advised to engage a third‑party inspection agency familiar with refractory products to conduct these checks. Proper documentation, including a commercial invoice, packing list and certificate of origin, will facilitate customs clearance in the destination country.
