In recent years, the continuous development of China's machinery, automobiles, home appliances, and electronic information industries, such as large demand for mold, has become the biggest driving force for the rapid growth of China's mold industry, China's low-end mold has a strong competitiveness, and international buyers to China's procurement The proportion has been increasing year by year. On the other hand, the pace of transfer of mold production from developed countries to China has further accelerated. It is expected that in 2013 China's mold industry will experience a boom in production and demand, and will continue to grow rapidly in the future. As the working conditions of the mold become more and more severe, higher requirements are placed on the quality of the mold steel, especially the purity and isotropy of the steel. In order to meet the needs of the development of the mold manufacturing industry, mold steel is rapidly developing in the direction of diversification, refinement, and productization. Therefore, foreign countries generally use "Electric furnace + furnace refining process" to produce high purity mold steel, for large section forging modules and large steel requirements vacuum treatment. For mold steels with higher purity requirements, most of them use electroslag remelting to further improve the cleanliness, density, isotropicity and uniformity of the steel and reduce segregation. Therefore, the quality has been greatly improved. In order to enhance competitiveness, the production of foreign tool steels tends to concentrate from decentralization, and a number of companies have conducted cross-border mergers to establish a complete technologically advanced die steel production line and mold steel scientific research base, forming several world-famous tool steels. Production and research center. We believe that Chinese companies should also follow the trend, accelerate the integration and restructuring of enterprises, increase investment in technology and materials research and development, and reduce the gap with mold enterprises in developed countries as soon as possible.
