Shaanxi Hua An Continuous casting Co., Ltd. (hereafter called Shaanxi Hua An), its predecessor is Xi’an Hua An Cast iron, which is affiliated to Xi’an University of Technology. Up till now, Shaanxi Hua An has four continuous casting producing lines, and all the main machines are operated by advanced digitalized intellectual controlling system. With two technologies of cupola furnace and medium frequency melting furnace, the molten iron is of steady and reliable quality, specializing in producing grey and ductile iron of Φ20---Φ360mm, □30×30---□280×280mm, rectangle, hexagon and other cross-section in various sizes. Its quality takes the lead at home, and Shaanxi Hua An has a productive capacity of 10000 tons per year. The enterprise is also “The Center for Research and Spread of China Continuous Casting and Rolling Austenpered Ductile Iron” (CASP) as well as a pilot base. It is one of the national key promoted projects for such characteristics as top quality, high efficiency, saving energy, protecting environment and so on. The enterprise owns five patents, some exclusive technologies and complete detecting apparatus and equipment including spectral analyzing apparatus. It has established long-term steady, powerful and reliable relationship for research and development. Some technologies and products are original and exclusive in China. Meanwhile, it has formed complete management structure by legal person and scientific strict quality management system to strive for building up its brand in the field of cast iron both home and abroad.
      With more than ten-year development, the enterprise has been in the lead in technology development and products’ quality in continuous casting iron in China, such honour as China Scientific Advancement, famous company honoring contract and promise, Honorable tax-paying enterprise, Honorable Manufacturing Enterprise, were given to the enterprise, its products have become well-known professional brand. It was awarded the certificate of Adopting International Product Standard by National Technology Supervision Bureau in 1998; its products were placed on the list of the products recommended to the market of E.E.C by China Council for the Promotion of International Trade (CCPIT) and French Scientific Quality Supervision and Evaluation Commissioner (ATN). Shaanxi Hua An has received ISO9001:2000 certification in October 2002.
      Grey and ductile cast iron bar of Φ30 mm and smaller size manufactured by the enterprise is an exclusive product in China; Series of cast irons of the bogey of high-speed train specially for AUBEITO is preferable recommended by Railway Department; section bar for hydraulic valves is supplied to Bosch Rexroth (Changzhou) Co., Ltd. after being tested and qualified by German Loue Laboratory; section bar exclusively for high-line rolling machine of air-cooling roller is supplied to Shanghai Baoshan Iron and Steel company, Shoudu Iron and Steel Company. At the same time, it has established long-term goods-supplying relations with such company as Scot Industries, Inc. (USA), Nipponchuzo Co., Ltd. (Japan), Bharat Malleables Pvt Ltd.
