Zhengzhou Annec Industrial Co., Ltd.is a stock company integrated hot-blast stove designing, project contracting, refractory material producing and selling. ANNEC owns 3 exclusively-invested subsidiary companies, 1 joint venture, and 1 R & D center, possessing over 1,000 modern processing equipments, and 5 high-temperature tunnel kilns with an annual refractory output of 180 thousand tons including 60 thousand tons of silica products, 60 thousand tons of high alumina products, 40 thousand tons of fireclay products, and 20 thousand tons of light-weight insulating materials and unshaped refractory materials.

ANNEC has a perfect quality control system, which has been approved and registered against the quality management standard of ISO 9001: 2000. And because of its advanced and complete measuring and checking equipments, ANNEC won the title of "provincially excellent institute of quality inspection".

ANNEC is strong in technological force by employing 9 well-known experts including Professor Wu Qichang, an iron-smelting designing master in China, Professor Zhang Bopeng from Shougang International Engineering technology Co., Ltd, Professor Sun Gengchen, a refractory expert enjoying special allowance from the State Council etc. to devote to the company's technological innovation and R & D. Besides, ANNEC has established a long-term and stable cooperation with Luoyang Institute of Refractory Research, Wuhan Science &Technology University, Capital Engineering& Research Co. Ltd., CISDI Engineering Co., Ltd., WISDRI Engineering & Research Incorporation Limited, Huatian Engineering & Technology Corporation MCC, Sino-steel Equipment & Engineering Co. Ltd., focusing on the development of refractory materials for metallurgical industry.

ANNEC also possessed advanced technology, assimilating techniques from world-known companies such as KALUGIN of Russia, NIPPON STEEL of Japan, DANIELI CORUS of Italy, VAI of Britain, SMS DEMAG of Germany etc., established a simulated, cold-state testing burners for top-burning hot-blast stoves, obtained national patents for its beehive checkers of 19 holes, 31 holes, 37 holes, 61 holes and wave-shaped multi-holes. Its 19-hole, 37-hole, 61-hole beehive checkers, andalusite bricks of high RUL and high resistance to thermal shocks, silica bricks of high density and high thermal conductivity for hot-blast stoves have been graded as the "high-tech products in Henan Province". Cooperating with Zhengzhou University to form an industry-education base makes the company keep abreast with or even ahead of international counterparts in terms of technical competency involving refractory materials suitable for torpedo ladle, hot metal ladle, steel ladle, middle ladle and hot air furnace etc.
