What 郑州科瑞(集团)耐火材料有限公司 does

Zhengzhou Kerui (Group) Refractory Materials Co., Ltd. is a private Chinese refractory materials manufacturer founded in 2004 and headquartered in Xinmi City, Henan Province — the historical center of China's refractory industry. The company operates a 186-mu production base (~124,000 sqm) with nearly 50,000 sqm of workshop space, producing over 200 product varieties across shaped refractory bricks (high-alumina, fireclay, corundum, mullite, silicon carbide, magnesia), unshaped monolithics (castables, mortars, gunning/ramming mixes), and functional refractories (honeycomb ceramic regenerators, refractory balls). Annual production capacity is 150,000 tons of shaped products and 50,000 tons of unshaped products, supported by 2 automated batching lines, 2 high-temperature natural gas tunnel kilns (168m each), 20 CNC hydraulic presses (400-1000T), and a DCS digital production control center. The firm holds proprietary intellectual property for carbon anode baking furnace refractory bricks and ISO 9001/14001/45001 certifications, and was recognized as a Henan Province High-Tech Enterprise.

The company serves industrial manufacturers across steel, non-ferrous metals (aluminum, copper, lead, zinc smelting), power generation, cement/lime, and hazardous waste incineration — both in China and across more than 100 countries and regions internationally. Go-to-market combines enterprise field sales with technical engineering support, EPC turnkey project services for full-scope kiln furnace lining solutions, and a digital-first marketing approach via Baidu search and Baidu Ai Procurement (since 2015) supplemented by 8-10 international and domestic exhibitions annually (Russia METAL-EXPO, Turkey ANKIROS, Shanghai, Jiangxi). The customer base exceeds 5,000 enterprise accounts, anchored by long-term relationships with Nanshan Aluminum (南山铝业), Shenhuo Group (神火集团), and Xinfa Group (信发集团). Revenue is generated through quote-based direct sales of refractory products and EPC project services; specific revenue is not publicly disclosed.

The company is founder-owned and operated, led by Chairman Wei Songchen (魏松晨) and General Manager Wei Yuehui (魏跃辉), with no external private equity or venture capital backing and no public listing. Recent strategic activity includes establishing a Zhengzhou West District branch and a new Xinmi subsidiary in March 2024, commissioning a new factory in 2025 to materially expand capacity, and adding functional refractory product lines (honeycomb ceramic regenerators). The firm is actively deepening international export pipelines through visiting delegations from Russia, Kazakhstan, Italy, Thailand, Korea, and Malaysia.
