Stainless steel coloring technology has long been widely used in Japan, but the problem is that it cannot be continuously produced. For example, steel plates need manual shearing to limit their length. New Japan Iron Company has developed a continuous coloring technology for stainless steel. The problem of continuous coloring production of stainless steel, which has attracted worldwide attention, has been solved by an enterprise in China. For a long time, ordinary color coated steel plates have swept the building materials market with the advantages of convenience and practicality, but there are defects such as poor corrosion resistance, strength and toughness of materials, and stainless steel has strong corrosion resistance and ductility, however, due to the single color of the material, it is easy to reflect, which is neither beautiful nor light pollution. Tianyuan manganese industry relies on rare earth stainless steel hot rolled coil and coloring technology with independent intellectual property rights. On the premise of not increasing steel production capacity, through advanced 'cold rolling? D Coloring 'short process production process produces new rare earth color steel plate materials with high strength, strong corrosion resistance, long service life, saving Ni-Cr metal, low production cost and high added value, the integration of stainless steel main body and coloring layer is realized. According to analysts of Huaxia mould network, the technology has won 9 national invention patents and the total investment of the whole project is 87. 5%. 0. 8 billion yuan, after completion and production, the annual total industrial output value will be 28 billion yuan, and the profit and tax will be 3. 9 billion yuan. The scale of the first phase of construction is 300 thousand tons, with an investment of 34. RMB 0. 6 billion. At present, the main project construction of cold rolling section and coloring section has been completed and the equipment installation stage has entered. The second phase of the project is planned to start construction in June 2013.
