Zibo Huaqing Refractories Co., Ltd., founded in the mid-eighties, mainly produces top-grade refractory materials and high-temperature industrial furnace linings. The company carries on modern enterprise system, and follows the tenet: “Develop by High Technology, Win Credit by Superior Quality, Market by Perfect Service”. Through years of efforts, the company can produce new top-grade refractory materials for such industries as petrochemical, carbon black, coal chemical, metallurgy, non-ferrous metal, quartz glass, etc., and has become a pilot base of China’s scientific research of building materials and the designated production enterprise of Sinopec.
The company has more than 60 medium- and - senior technicians and a R&D center with leading technology, advanced equipment and complete testing facilities. Our main products include over 100 varieties: corundum refractories, zirconia refractories, high chrome brick, alumina-carbon refractories, magnesia-carbon refractories, alumina amorphous refractories, light insulating refractory lining, etc., of which some hit products such as top-grade corundum refractory products, top-grade refractory wear-resistant castables, zirconia products, and light insulating linings, etc. are very popular not only in China, but also in USA, Japan, Korea and the Southeast Asia.
In the principle of “Guide by Technology, Survive by Quality”, the company has been cooperating with domestic research institutes to push out new materials, new technologies and new varieties. So far, more than 20 items were awarded provincial, municipal “Spark Plan Prize” and “Science & Technology Progress Award”, and 2 items have obtained state patent of utility model. The company has built up the management system integrating research, development, production, testing, operation and service. In Nov. 2009, the company passed the certifications of GB/T19001-2008/ISO9001:2008 (Version).
The company is located in Zibo, Shandong, adjacent to Qingdao (known as “Oriental Switzerland” ) in the east, Ji’nan (known as “City of Springs” in the west, Taishan Mountain in the south, and Dongying (an emerging city of petroleum industry) in the north, with Jiaoji railway and expressways (Jiqing, Binbo, Dongqing, etc.) passing through, enjoying convenient transportation by land, sea and air.
