Founded in 1968, our company has developed into a modern large-sized enterprise mainly specialized in the production of refractories for iron-making system. The company is composed of eight branches, they are: Gongyi Winna Science and Technology Development Co., Ltd, Gongyi High-efficient Refractories Co., Ltd, Zhengzhou Jianxing High-tech Furnace Materials Co., Ltd and Luoyang Refsource Industry & Trading Co., Ltd...Occupying a land area of 300000m2, the company has fixed assets of 150 million Yuan, current assets of 250 million Yuan, with 2000 employees including 280 technicians, 85 engineers. With annual output of 200 thousand tons of various refractories widely applied in high temperature furnaces in the industries of metallurgy, building materials, ceramics, petrol chemistry and machinery, we have sold our products to over 200 customers in more than 30 provinces or cities in China and exported to more than 10 overseas countries and regions such as America, Japan, Russia, Holland, India, Brazil, Turkey, Italy, Ukraine, Kazakstan and Mexico.

Persiting in the guidelines of "Developing on Quality and Progressing on Science and Technology", we have successively established cooperation relationship with universities and scientific research institutes such as Wuhan University of Science and Technology, Wuhan Iron and Steel Design Institute, Luoyang Institute of Refractories Research, Wuhan Institute of Metallurgy Building Materials and Henan University of Science and Technology. Being strong in research and development, we have successfully developed low creep bricks series for BF and HBS, ceramic cup series product for BF, mould pressed micropore carbon bricks, sintered micropore alumina carbon bricks, Al2O3-SiC-C series product for hot metal pretreatment, mullite cordierite bricks and various monolithic refractories, some of which have reached to the international advanced level or the domestic leading level in terms of technologies and even filled the gaps in refractories technology in China. In 1990, our company passed the quality verification system GB/T 19001-2000-ISO 9001: 2000 and awarded the title of "Henan High-tech Enterprises". Especially, our micropored corundum bricks and high thermal conductivity mould pressed micropored carbon bricks were awarded the national technical invention patent.

We invited Prof. Lin Binyin from Wuhan University of Science and Technology as chief engineer and the technical strength has been improved continuously. We have formed R & D team supported by some well-known experts on refractories from Wuhan University of Science and Technology and Henan University of Science and Technology; Furnace-design team technically supported by Wuhan Iron & Steel Design Institute; Pre-assemble and installation team supported by China First Metallurgical Constitution Corporation, all of which guarantee our production, quality and in situ services. We have already provided hundred thousands tons of refractories for over 100 BF, HBS and steel making system for many modernized steel corporations such as Baosteel, Anshan I & S Co., Wuhan I & S Co., Shoudu I & S Co., Panzhihua I & S Co., Ma'anshan I & S Co., and Benxi I & S Co. And have undertaken the design, production and pre-masonry and pre-assembling projects for dome, pipleline, burner port, tuyere, slag notch, taphole and ceramic cup masonry, which have gained highly praises from our customers. Currently, we are the excellent supplier of refractories for Baosteel. In 1988, we first produced andalusite bricks for 3200m3 BF of Wuhan I & S Co. In cooperation with Danieli(former Hogowen) in China; In 2001, firstly we provided refractories which adopted Kalugin Technology from Russia for 750 m3 BF and HBS of Laiwu I & S Co. Which played a significant role in the application of Kalugin and Danieli technology and the longevity of BF and HBS.
