Zhengzhou Haixu Abrasives Co., Ltd supplies industrial chromite sand in the AFS grades 25-30, 30-35, 35-40, 40-45 and 45-50, each produced from mined chromite ore. The sand is marketed for its high Cr2O3 content, which gives strong thermal stability during high-temperature processes. Grain size is controlled to the AFS specification, providing consistent particle distribution for casting operations. The supplier notes a low expansion rate and an eco-friendly sourcing practice.
Typical chromite sand contains 45-55 % Cr2O3, less than 2 % SiO2 and a bulk density around 2.7 t/m³, values that align with industry standards for refractory-grade abrasives. The AFS25-30 grade usually ranges from 0.025 mm to 0.030 mm in particle diameter, while the AFS45-50 grade spans 0.045 mm to 0.050 mm, offering predictable flow characteristics. Low moisture (<0.5 %) and minimal expansion (<0.02 % per 1000 °C) help reduce casting defects. Such properties make the sand suitable for metal casting, refractory brick production and glass melting.
Foundries, metallurgical plants and glass manufacturers commonly purchase this sand to improve mould integrity and surface finish. Zhengzhou Haixu offers flexible minimum order quantities and can ship under FOB or CIF terms from Chinese ports. Buyers should request a mill test report and confirm the exact grade, packaging size and any required certifications before placing an order. Payment and delivery details are negotiated directly with the supplier and should be recorded in the purchase contract.

Before placing an order, importers should verify the exact AFS grade, request a recent mill test report showing Cr2O3, SiO2, FeO and moisture values, and confirm that the sand meets any project-specific refractory standards. It is prudent to ask for a sample batch to assess grain size distribution and expansion behaviour. Documentation of the source mine and environmental compliance should also be requested.
Zhengzhou Haixu ships from major Chinese ports on FOB or CIF terms; buyers need to agree on the preferred incoterm and arrange freight forwarder details. Lead times are not disclosed publicly, so the importer should request an estimated dispatch schedule, typically ranging from two to four weeks after order confirmation. Common payment methods include T/T in advance, L/C at sight or open account after a satisfactory trial shipment.
Upon arrival, the cargo should be inspected for bag integrity, moisture content and any visible contamination. An independent third‑party lab can perform a grain‑size analysis and an expansion test per ASTM D-761 to confirm compliance with the agreed specifications. Retaining the mill test report and shipping documents will support any claim for replacement or discount if the material deviates from the agreed standards.
