Henan Songrui New Refractory Materials Co., Ltd. is located in Xuanhua Town Industrial Park, Dengfeng, Zhengzhou, Henan Province, China. It is a comprehensive enterprise that integrates the research, development and manufacturing of new refractory materials with the design and construction of kiln equipment.
With years of deep engagement in the high-temperature industry, the company's main business covers kiln equipment such as activation furnaces (rotary activation furnaces and Slep furnaces), carbonization furnaces, and fluidized bed chemical vapor deposition (FB-CVD) reactors, as well as the research, production and furnace lining construction of supporting refractory materials. We provide integrated services for customers in the activated carbon, silicon-carbon anode, carbon nanotube and related industries, spanning equipment selection, process design, installation and commissioning, maintenance and retrofit.
Upholding the principle of "quality first, customer foremost", the company relies on its in-house refractory production line and kiln engineering team to ensure the compatibility between equipment and furnace lining materials as well as the reliability of project quality. We sincerely welcome customers to visit and inspect our plant and discuss cooperation.

View All →Improving Activated Carbon Yield: Five Loss Points from Feed to Product
Activated carbon yield passes five loss points: 12–20% feed moisture, 70–80% volatiles lost in carbonisation, 3–12% screening fines, 35–50% activation burn-off and 2–5% in washing and drying. Each stage comes with a realistic range and the parameters that move it, plus the rule that every 100 mg/g of iodine value costs 4–7 points of yield.
Waste Heat Recovery on Activation Furnaces: Three Options and Payback
Three heat recovery routes for activation furnaces: an off-gas boiler raising 0.8–1.6 MPa steam back to activation (RMB 0.6–1.2 million for 4 t/h, 1.5–3 year payback), an air preheater taking combustion air to 150–250°C (RMB 0.2–0.5 million, 1–2 years), and hot air to drying (RMB 0.4–0.9 million, 2–4 years). Also explains why heat below 120°C rarely pays.
Slep Furnace Structure and Process: Why Dual-Medium Activation Yields Finer Micropores
How the Slep furnace works: vertical channels, regenerators and alternating steam/flue-gas activation at 1100-1200C, why the 20-40 min reversal cycle matters, and why it suits granular shell carbon but not powder.
