What Zhengzhou Kerui (Group) Refractory Co. does

Zhengzhou Kerui (Group) Refractory Co., Ltd. is a privately held Chinese refractory materials manufacturer founded in 2004 and headquartered at the Chaohua Industrial Area in Xinmi City, Henan Province. The company designs, produces, and ships a catalog of more than 50 refractory SKUs grouped into refractory bricks (high alumina, corundum, fused AZS, mullite, fire clay, silica, magnesia series, magnesia-chrome, magnesia-carbon, magnesia-alumina spinel, magnesia-iron spinel, silicon carbide, alumina-silicon carbide, acid proof, graphite crucibles, and refractory balls), monolithic refractories (high alumina, mullite, corundum, SiC, Al-Mg, ladle, insulating, non-stick aluminum, acid-resistant castables; AZS ramming mass; calcium aluminate cements CA50/CA70/CA80; refractory mortar; and raw materials including alumina powder), ceramic fiber products (board, blanket, module, rope, paper, cloth, cotton), insulating bricks, and RBSIC/SiSiC silicon carbide kiln furniture plus honeycomb ceramic regenerators for HTAC systems. Applications span steelmaking ladles, AOD converters, BOF and EAF furnaces, cement and lime rotary kilns, aluminum and non-ferrous melting/holding, CFB boilers, petrochemical cracking furnaces, and waste incinerators, with products rated for service up to 1800°C.

The company operates a 50,000-square-meter factory with stated 250,000-ton annual production capacity, employs approximately 500 people, and reports 1,700+ completed cases and 800+ customers across nine geographic regions including EMEA, South Asia, North America, the Middle East, Eastern Europe, North Africa, East Asia, Southeast Asia, and Western Europe. Manufacturing is governed by a documented 12-step QC process incorporating XRF analysis, density/porosity testing, cold crushing strength, ISO 3187 thermal shock resistance, and 5-year batch sample retention; the company holds ISO 9001, ASTM, EN, GB certifications and selected REACH/RoHS compliance, alongside 1 invention patent and more than 20 utility model patents.

Revenue is generated through direct B2B sales via a multilingual website (15+ languages) supplemented by WhatsApp and Tawk.to live chat, with on-site commissioning support included. Pricing is per-ton FOB ($300-$5,000/ton depending on alumina content, formulation, and customization) under multi-year contracts. Customer testimonials cited in marketing materials cite outcomes such as 40% better thermal shock resistance versus competitors, 25% annual refractory cost reduction, and 18% energy savings on a co-developed chrome-free spinel brick for hydrogen-based DRI steelmaking, indicating a positioning that combines commodity-scale supply with engineered custom solutions for industrial furnace operators.
