China's foundry industry cluster is not modern enough
China's foundry industry cluster is still not modern enough
Since the reform and opening up, casting has been flourishing as the foundation of the equipment manufacturing industry. The total output of castings ranks first in the world for 10 consecutive years since 2000, and reached 33.5 million tons in 2008, accounting for about one-third of the world's total casting production. At present, the total number of founding enterprises is about 30,000, and the number of employees is more than 1.5 million. China is a veritable founding power. The development of the foundry industry has strongly promoted the advancement of the machinery industry, the aerospace industry, and the national defense industry, especially promoting the steady development of Chinese automobiles, machine tools and other products on the international market. Luo Baihui, a member of the association, pointed out that China's current casting industry is growing steadily in a steady development, which will make a huge contribution to the development of China's national economy.
According to Luo Baihui, China's foundry industry has achieved three major advances:
(1) The structure of cast alloy is further optimized, and the proportion of high specific strength alloy is significantly improved. In recent years, ductile iron, austempered ductile iron and vermicular graphite cast iron are widely used in mechanical products; high performance aluminum alloy and magnesium alloy are also widely used. application.
(2) The level of casting technology has been greatly improved; at present, China has been able to independently produce large-scale castings with high quality and complicated technology, such as large-scale turbines, steam turbines and gas turbines, wind power and large engine blocks and cylinder heads. The situation of large castings and forgings subject to foreigners has changed. At present, the largest spheroidal graphite iron castings produced in China are 135t, and the largest steel castings are 520t. More than 40 castings can produce more than 30t single castings. A small number of foundry companies have approached or reached world-class levels.
(3) Management modernization, awareness of energy conservation and environmental protection. Continuous improvement of management level is the source of power and important guarantee for enterprise development. Many foundry enterprises in China have passed ISO9001, ISO14001, OHS18001 certification, and implemented 5S management on site. The benefits to management have become the consensus of the foundry industry. At the same time, the company's awareness of environmental protection and social responsibility has been continuously enhanced. The investment in dust removal and environmental protection has continued to increase. The recycling of old sand and the utilization rate of waste water and waste oil are getting higher and higher.
"China's foundry production has ranked first in the world for nine consecutive years, and production is about three times that of the second largest US production." Luo Baihui believes that the characteristics of China's foundry industry are still strong, and the modernization of industrial clusters still exists. The degree is still not enough.
Luo Baihui pointed out that taking the foundry industrial park and the foundry industry cluster as the carrier, taking the casting industry access system as the starting point, relying on science and technology as the support, combining market allocation with government guidance, giving full play to regional advantages and resource advantages, and realizing casting in various regions. Industry's complementary advantages and cluster effectiveness, promote management lean, technological progress, product upgrades, promote energy-saving emission reduction and resource optimization, adhere to both economic and social benefits, and take advantage of resource-saving, environmentally friendly, and socially harmonious The road to sustainable development is a strategic measure to realize the transformation of China's foundry industry from large to strong.
Clarify the layout of industrial planning to promote the development of casting upgrade
According to Luo Baihui, China's foundry industry should be clear about the overall planning and layout. Its system framework mainly includes casting raw and auxiliary materials industry cluster, foundry equipment industry cluster, characteristic craft casting products and regional industrial clusters, characteristic casting industry cluster, casting industry education and training base, industrial chain extension related industrial cluster, foundry research and development center and foundry specialty. Eight areas, such as exhibition and online magazines, and other cultural industries, focus on cultivating and supporting the construction and development of characteristic industrial clusters. To make detailed regional planning for the development of China's foundry industry, and also lay a solid foundation for the development of China's foundry industry cluster, and make great contributions to the transformation and upgrading of China's foundry industry.
