Import Carbon Block — Buy in Bulk from Supplier in China

Carbon block is a carbon refractory material primarily used in metallurgical applications, especially as lining masonry for high-temperature furnaces. This supplier specialises in electric furnace carbon blocks, which are engineered for thermal shock resistance, elevated temperature strength, low thermal expansion and anti-corrosion properties. Typical applications include calcium carbide furnaces, ferroalloy furnaces such as ferro silicon, silicon metal, phosphorus, silicon manganese, calcium silicon and tin furnaces.

The blocks are manufactured in standard grades with half-graphite composition, offering a balance of mechanical and thermal performance for extreme environments. Ash content is maintained at 6% by weight, while true density measures 1.90 g/cm³ and compression strength reaches 38 MPa. Volume density is 1.55 g/cm³, breaking strength is 9.8 MPa and porosity is controlled at 18%, ensuring structural integrity under operational stress. These properties align with typical industry standards for carbon refractories used in electric arc furnaces and similar installations.

Customisable dimensions are available, including 400x400x(400-1800mm), 400x500x(400-2500mm), 600x650x(600-2000mm) and 800x800x(800-1900mm), with length adjusted to customer requirements. Special variants, such as furnace mouth carbon blocks, can also be produced. The supplier packages products on ordinary wooden pallets or fumigation trays with steel belt securing, and accepts payment via cash or letter of credit. Buyers typically source these blocks for long-term industrial use in metal production and alloy smelting.

Ningxia Carbon Valley International Co., Ltd. is based in Xingqing District, Yinchuan, Ningxia, China, and operates as a supplier of carbon-based refractory materials. The company holds a harbor trust tier, indicating a baseline level of verified operational presence, though its response rate and average response time are currently not available, suggesting limited recent engagement or updated communication metrics.

The supplier’s product portfolio includes carbon blocks, graphite blocks, carbon additives, electrodes, cold ramming paste, electrode paste, silicon carbide and calcined petroleum coke. These materials are marketed for use in metallurgical and industrial applications, with documented exports to regions such as Japan, Taiwan, Korea, India and America. The company does not provide additional details on production capacity, certifications or facility-specific attributes beyond the product specifications listed.
