Focus on the field of casting raw and auxiliary materials for 20 years

"Under the background of the Fourth Industrial Revolution characterized by quantitative integration, today's foundry industry should comply with new demands, new supplies, and new kinetic energy, and explore a development path that is driven by innovation." China recently Xue Linghu, president of the Foundry Association, gave a comprehensive explanation of the current situation and future development trends of the foundry industry.

Xue Linghu said that in the future, China's foundry industry will not only change from big to strong, but also have more rules to follow in terms of environmental standards and standards.

Production ranks first in the world

Xue Linghu, president of the China Foundry Association, said that casting is the foundation of the equipment manufacturing industry, and China is a major foundry country. The output of castings has ranked first in the world for 16 consecutive years since 2000. The current output exceeds 45 million tons, accounting for more than 40% of the global total output. .

The number of foundry companies in China currently is about 26,000, and the number is declining year by year. The output concentration of large-scale foundry companies continues to increase, among which the top 4,500 companies account for more than 70% of the total output, and the average annual output of foundry companies From 1,320 tons in 2010 to 1,754 tons in 2015, the concentration has continued to increase.

Speaking of the achievements made in the current development of the foundry industry, Xue Linghu introduced that the quality of castings has steadily improved. With the improvement of the technology and equipment level of China's foundry enterprises, the quality of China's casting products has steadily improved. Especially in the automotive, internal combustion engine, machine tool, power generation equipment, electric power, rail transportation and other industrial fields, a number of large-scale, professional casting enterprises with high quality levels have formed. The independent manufacturing capabilities of key castings have been further improved. The dimensional accuracy, surface quality and intrinsic quality of some castings have reached international advanced levels, and the export grades of castings have been greatly improved.

In recent years, large-scale foundry companies in China have generally invested heavily in foundry equipment during the construction of new projects and technological transformation. Many companies have adopted high-efficiency and energy-saving melting equipment, automatic molding lines for clay sand, large-scale self-hardening resin sand production lines, and advanced aluminum alloy high / low pressure casting equipment. At present, the overall equipment level of a few domestic-scale foundry companies has been comparable to that of developed foreign industrial countries. These enterprises rely on advanced process technology and equipment to support the production of key castings for domestic mainframes and major technical equipment, and have become an important force for the independent domestic manufacturing capability of key castings in the fields of automobiles, energy (nuclear power, wind power, hydropower, thermal power), rail transit and other fields And has the ability to compete in the international market.

The degree of specialization in the production of raw and auxiliary materials for casting has been greatly improved. The scale of China's casting production is huge, which requires a large amount of raw material supply and guarantee. After years of rapid development, China's foundry raw and auxiliary materials companies have become more and more specialized, forming a group of raw and auxiliary materials production bases for foundry pig iron, foundry coke, foundry sand, and binders. Advanced level, and occupy a certain share in the international market.

The manufacturing level of domestic foundry equipment and molds has improved significantly. To meet the development needs of domestic foundry enterprises, China's foundry equipment manufacturing level has developed rapidly. Through the introduction, cooperation, digestion of foreign advanced casting equipment, and increased investment in independent research and development, China has formed a group of foundry equipment manufacturing enterprises with independent research and development capabilities. Some enterprises have advanced international standards. While meeting the needs of domestic casting enterprises, they also export. international market.

The "green casting" sustainable development concept has been strengthened. During the "Twelfth Five-Year Plan" period, China's foundry enterprises invested significantly more in energy-saving equipment, environmental protection and safety protection facilities than during the "11th Five-Year Plan" period. The concepts of “green casting” such as energy saving, emission reduction, and occupational health and safety have been increasingly strengthened in the foundry industry. The proportion of waste (old) sand recycling in foundry companies has been increasing year by year. A number of green casting demonstration companies have emerged in China's foundry industry.

The industrial layout becomes more reasonable. Driven by the factor market, the foundry industry is more rational in its industrial layout. Under the background of resource and environmental constraints and rising labor costs, the gradient transfer of China's foundry industry to the central and western regions is accelerating. The construction of the foundry industry clusters and industrial parks has been faster. development of.

Access system optimizes industry structure

Xue Linghu believes that China's foundry industry is large but not strong. Although the concentration of the industry has continued to increase, it is still far lower than that of industrial developed countries. Due to history and level of development, compared with developed countries, there are still a number of "scattered, chaotic, and poor" foundry companies in China. These companies are mainly small-scale foundry companies with relatively backward technology and equipment, especially inadequate environmental protection equipment. Although its output of castings is relatively low, the total amount of pollutant emissions accounts for an absolute proportion, which seriously affects the overall image and reputation of the foundry industry.

With the in-depth implementation of China's "foundry industry access system", the industrial structure adjustment of the foundry industry has been strengthened, backward production capacity of the foundry industry will be eliminated rapidly, and the number of foundry companies nationwide will continue to decrease. It is expected that during the "Thirteenth Five-Year Plan" period, China's casting output will enter a stage of low and medium-speed growth, with a growth rate of less than 4%. By 2020, China's annual output of castings will reach about 55 million tons. Under the new normal state of low and medium-speed growth in casting output, the material structure of castings will be further optimized. The proportion of aluminum (magnesium) alloys and ductile iron castings will continue to increase; the annual growth rate of automotive and rail transit castings will continue to lead other industries. Due to the impact of the “re-industrialization” strategy that developed industrial nations have started to reshape the new competitive advantages of manufacturing industries, and that some developing countries are accelerating their participation in global industrial re-division and undertaking the transfer of manufacturing industries, China ’s international trade market for castings will face “two-way squeeze ", But the export of castings is expected to maintain a small growth, and the export castings will develop in the direction of higher value-added mid-to-high-end castings.

Throughout the United States, Germany, Japan and other manufacturing powers, foundry and other basic manufacturing industries are their strong support to become manufacturing powers, and have formed a number of industry invisible champions. China is on the way to the development of a manufacturing power. There is no substitute for the basic tasks of foundry and other basic manufacturing in supporting the construction of a manufacturing power.

With the development of China's urbanization, new industrialization and strategic emerging industries, it has brought new expansion space for the development of the foundry industry. The state has issued "Made in China 2025". China's equipment manufacturing industry will accelerate its move to the mid- to high-end in accordance with the strategic needs of a manufacturing powerhouse, which will inevitably bring new opportunities to its underlying foundry industry. In addition, the implementation of the national “Belt and Road” strategy will create more industrial cooperation opportunities for China and neighboring countries along the “Belt and Road”, and the foundry industry will go deeper into the international market together with our equipment. And from a global perspective, a new round of scientific and technological revolution will trigger a change in the way global industries develop, and the accelerated integration of the Internet and the traditional casting industry will accelerate the realization of intelligent casting.

The environmental protection rules and regulations of the foundry industry will be more rule-based.

In fact, in recent years, the foundry industry has developed rapidly. Many foundry companies are equipped with comprehensive environmental protection equipment, and air pollutant emissions have been effectively controlled to a certain extent. As the industry association of the company's maiden, it should give full play to the advantages of being familiar with the industry, reflect the demands of the company in a timely manner, and guide the company to self-discipline. Specifically, comprehensive management measures such as environmental protection can be used to strengthen the comprehensive management of "scattered, disordered, and poor" foundry enterprises with incomplete environmental protection equipment and emissions that do not meet the standards; meanwhile, in order to meet the needs of national environmental protection, the revision of related emission standards related to the foundry industry is accelerated , Establish a long-term mechanism to promote environmental protection governance in the foundry industry.

The China Foundry Association group standard "Emission Limits of Air Pollutants in the Foundry Industry" will be released in June 2017. The National Standards for "Emission Standards for Air Pollutants in the Foundry Industry" formulated by the Ministry of Environmental Protection and entrusted by the China Foundry Association will be released at the end of 2017 Implemented in June 2018. At that time, there will be standards to follow in the emissions control of the foundry industry.
