Panzhihua Iron and Steel - praised by foreign metallurgical experts as "a miracle in the history of world metallurgy". Panzhihua Iron and Steel - also known as "Ivory Micro-Carved Steel City". Panzhihua Iron and Steel - built on an abrupt hillside, is a large-scale enterprise with an annual output of 3 million tons of steel. Among the world's steel enterprises, Panzhihua Iron and Steel Co., Ltd. covers an area of only 2.5 square kilometers. The iron ore used by Panzhihua Iron and Steel Co., Ltd. is the most difficult polymetallic symbiotic ore in the world. Smelting this vanadium-titanium magnetite in an ordinary large blast furnace has been the dream of many metallurgical experts in the world for more than a century. After a lot of research and experiments, this technical difficulty was overcome by the Chinese, and qualified molten steel was smelted from the Panzhihua iron ore rich in vanadium, Chin, gallium, scandium and other rare metals. The completion of this project not only made Panzhihua Iron and Steel's equipment level a big step forward, but also made a fundamental change in Panzhihua Iron and Steel's product structure, no longer only can produce primary products of steel. In particular, the rolling system can not only produce special steels such as railway rails, but also various sheet products with a wide range of applications. Panzhihua Iron and Steel's railway rails are very famous in the world, not only for domestic use, but also exported to foreign countries in large quantities. The steel rails produced by Panzhihua Iron and Steel Co., Ltd. using new technological achievements have doubled the service life. Panzhihua Iron and Steel has formed a series of large-scale steel products mainly made of steel rails, and the products are very popular at home and abroad. Panzhihua Iron and Steel's sheet products are now the best raw materials for China's home appliance, automobile and other manufacturing industries. In addition to iron and steel products, Panzhihua Iron and Steel is also a major producer of vanadium products in the world. Its products account for more than 80% of the domestic market and 15-18% of the international vanadium market. It is an important export base in my country. Panzhihua Iron and Steel's titanium products have also formed a certain scale, not only supplying the domestic market, but also exporting to foreign countries.
