High Alumina Castable
High Alumina Castable is a pre‑mixed refractory material offered by Gongyi Hongda Furnace Charge Co. Ltd in China. The composition includes high alumina raw material with 60 - 85% Al₂O₃ and a calcium aluminate binder that provides structural cohesion after curing. It is supplied as a castable mix ready for shaping and installation in furnace linings, kilns and steel‑making equipment.
Typical density for this class of castable is about 3.0 g/cm³ and typical compressive strength reaches 120 MPa at 1,200°C, allowing it to withstand severe thermal cycling. The material sets within 30 - 45 minutes at 25°C, facilitating rapid installation, while the maximum service temperature is typically up to 1,600°C. Thermal conductivity is usually around 1.4 W/m·K at 1,000°C, which helps to minimise heat loss during operation.
The castable is widely used by construction firms, foundries and large‑scale industrial projects that require a durable refractory lining. Bulk shipments are commonly packed in 25 kg bulk bags, ready for on‑site mixing and placement. As the listing does not specify minimum order quantities, pricing or lead‑time, buyers should confirm these parameters directly with the supplier before committing to a purchase.

Gongyi Hongda Furnace Charge Co. Ltd operates from Gongyi Refractory Industry Park in Henan, China (postal code 451200). The supplier holds a harbour trust tier and a recorded response rate of 0.00, meaning no response metrics are available on the platform. The company focuses on refractory products, including high alumina castables and related raw materials for industrial furnace applications.
The listing details the material composition, binder type and general performance characteristics but does not provide MOQ, price or lead‑time information. Prospective buyers should reach out directly to obtain a detailed quotation, confirm any certification status and request sample test reports as needed.
High alumina castable is a pre-mixed refractory composition designed for forming heat-resistant linings in industrial furnaces, kilns, and steel-making equipment. With alumina content typically ranging from 60% to 85%, it offers superior thermal shock resistance and structural integrity at temperatures exceeding 1,500°C. This product is widely sourced by construction firms and foundries engaged in heavy industrial projects, and is traded globally in bulk bags or loose form for large-scale installation contracts.

Sourcing High Alumina Castable from Gongyi Hongda Furnace Charge Co. Ltd - China Import Guide
Importers should first request a mill test report confirming the alumina percentage, binder type, density and compressive strength of the batch. Verifying the particle size distribution and moisture content will help ensure the mix meets the required workability and performance standards before on‑site casting.
Shipments from Henan are typically routed through the nearest seaports such as Shanghai or Shenzhen. Buyers need to agree on Incoterms - FOB, CIF or DDP - and clarify expected lead times, as production scheduling can affect delivery dates. Payment terms are usually negotiated per order, often requiring a letter of credit or advance payment prior to dispatch.
A third‑party inspection at the supplier’s facility is recommended to check the bulk bag integrity, bulk weight and any visible defects. After receipt, an independent laboratory can perform compressive strength and thermal conductivity tests on a retained sample to verify compliance with the quoted specifications. Ensure that the supplier provides a full set of documentation, including a material safety data sheet and any relevant ASTM or ISO compliance certificates, before customs clearance.
