Zhengzhou Annec mainly produces refractories for blast furnace, hot blast stove, torpedo tank, ladle, etc. and provides professional EPC service for blast furnace and hot blast stove. We have acquired some key technology that could achieve high blast temperature, long campaign and low energy consumption of hot blast stove. Zhengzhou Annec has four branches equipped with seven production lines that are capable of producing 150,000 tons of refractories each year. The four factories are Fuliang, Fuhua, Fugang and Fubao. We also have an affiliated Annec (Beijing) Engineering Technology Co., Ltd., and a provincial enterprise technology center.  Our annual sales revenue reached 800 million RMB in 2011.

Zhengzhou Annec has established a complete quality assurance system. We have been certified by an array of ISO standards, such as the quality management system ISO90012008, the environmental management system ISO14001:2004 and occupational health and safety management system GB/T24001:2001. We have a complete set of advanced measuring instruments and testing facilities. As a result, we have been evaluated as “Henan Eligible Enterprise for Quality Inspection” and “Provincial Enterprise Technology Center”.

We have a research and development team committed to thermal engineering and R&D of materials. The team consists of 13 national experts headed by national engineering design master Wu Qichang, our chief technology officer, and refractories doctoral supervisor Sun Gengchen.  

We have maintained sustainable and enjoyable cooperation with Beijing Shougang International Engineering Technology Co., Ltd., Sinosteel Engineering Design and Research Institute Co., Ltd., and subsidiaries of China Metallurgical Group Corporation, such as MCC Capital Engineering & Research Incorporation Limited and MCC CISDI. Some new and unique products developed by us can meet the latest development of the ferrous metallurgy and have beenexported worldwide to India, Turkey, South Korea, Germany, Japan, America, etc.

We have maintained cooperation with University of Science and Technology Beijing, MCC Capital Engineering & Research Incorporation Limited, and Shougang International Engineering Technology Co., Ltd., we have set up the world’s first integrated laboratory of CFD numerical simulation test, cold-state and hot-state simulation tests for Top-combustion hot blast stoves. It will provide valuable data for developing low-carbon and energy-conserving hot blast stove with long campaign and ultra-high temperature of above 1300and point to a guiding direction for the technical research in the supportive refractories.

We have absorbed advanced technology of world-known companies such as KALUGIN of Russia, NIPPON STEEL of Japan, DANIELI CORUS of Italy, Paul Wurth of Luxemburg, etc. We have provided refractories for more than 200 large- and medium-sized blast furnaces and hot blast stoves, such as Jiangsu Shagang 5800m3 blast furnace (P.W. external-combustion stove), Shougang Jingtang 5500m3 blast furnace (BSK top-combustion stove), Liaoning Bengang 4350m3 blast furnace and Shougang Qiangang 4000m3 blast furnace (DANIELI internal-combustion stove), Turkey ISDEMIR 2500 m3 (DANIELI internal-combustion stove), Baogang Meishan 4700m3 and Turkey ISDEMIR 3200 m3 blast furnaces (NIPPON STEEL of Japan external-combustion stove), Anyang Steel 4700m3 blast furnace, India ESSAR2200 m3 (KALUGIN of Russia top-combustion stove), India BIL 1800m3 (KALUGIN of Russia top-combustion stove), Indian Electrosteel Integrated 1050m3 (KALUGIN of Russia top-combustion stove), Tianjin Tiangang and Tangshan Steel 3200m3 blast furnaces (KALUGIN of Russia top-combustion stove), Jiangyin Xingcheng and Beitan Steel 3200m3 blast furnaces (Rotary-type top-combustion stove). Two of our patented products have occupied more than 80% of the market in China. They are burner of the top-combustion stove and 37-hole checkers.

We have provided turnkey service of refractories for more than 20 blast furnaces ranging from 600m3 to 1780m3 for numerous clients, including Hebei Jinxi Steel, Shandong Taishan Steel, Tianjin Rockcheck Steel, Changzhou Zhontian Steel, etc.

Our company has obtained 18 national patents, such as 37-hole checkers, 61-hole checkers, perforated wave-shaped cell-type checker brick, stressless outlet structure, swirl-type top-combustion hot blast stove burner, dual-channel vortex ceramic burner, reform from ball-type stove to top-combustion stove, reform of hot blast stove from internal-combustion to top-combustion, reform of hot blast stove from external-combustion to top-combustion, etc. Among our products, 19-hole, 37-hole, 61-hole cell-type checkers, AH series of andalusite brick with high RUL and high thermal shock resistance, were assessed as “high-tech products of Henan province” and multi-hole cell-type silica brick was assessed as “famous brand product in Henan province” and “high quality product in Henan province”. Zhengzhou Annec was awarded the first prize for Science and Technology Progress of Zhengzhou City and the second prize for Science and Technology Progress of Henan Province owing to the project called “Optimal Design of the Primary Refractories in the Top-combustion Hot Blast Stove and Research and Application of the AH Series Andalusite Bricks”. We were awarded the silver medal of excellent patents by MCC, the second prize of scientific progress by MCC, the third prize of scientific progress of Beijing city for the project “Innovation and Application of Swirling-type Top Combustion Stove for Large Blast Furnace”.We also set up bases of production and research with Beijing Science and Technology University and Zhengzhou University. These bases have helped our company take the lead in the production of torpedo tank, iron ladle, tundish, ladle and other refractories for hot blast stove. Our company has been acclaimed as “a creditable supplier” by Baoshan Steel, Hebei Steel, MCC CERI, and Shougang International for consecutive years.

We have been awarded plenty of honorary titles, including Famous Brand of China, An Outstanding Chinese Enterprise for Science & Technology Innovation, An Excellent Enterprise in Quality, Service and Credibility, An Excellent Credit Rating Enterprise in China, Henan High-tech Enterprise, Henan Excellent Refractories Enterprise, Henan Creditable Private Enterprise, Henan Top Ten Innovative Enterprises, Key High-tech Enterprise in Henan, A Leading Energy-conserving Enterprise, Zhengzhou Pilot Enterprise for Innovation, Zhengzhou Leading Enterprise in Environment Protection, etc.
