The Development of Cold Rolling Mills and Its Future in China
Rolled products were invented in the early 19th century in Europe and America. The first use was in train wheel axles to reduce wear between wheel axles and wheel flanges. Later, rolling technology used in the manufacture of cold rolled steel strips and plates, thereby eliminating deformation and fatigue of steel materials, improving product performance, increasing product yield and reducing energy consumption. Cold rolled steel strips and plates are ubiquitous in our daily lives, and are widely used in the production of automobiles, containers, household electrical appliances and various construction components. It is a key material for the development of modern society.
In China, cold roll mills were first imported from other countries in the 1950s and 1960s. With the continuous progress of Chinas mechanization and modernization, Chinas cold rolling production technology has also kept pace with the times, resulting in more and more domestic cold roll mills that meet international standards. The state has formulated a series of specifications, plans and standards for the development and promotion of cold roll mills.
At present, Chinas cold rolling industry is advancing rapidly, and its production capacity and market share are increasing steadily. Nowadays, more than 90% of the cold-rolled steel used in China is supplied by various types of domestic cold-rolling machines. The development of these cold rolling machines is mainly embodied in four aspects.
First, the design and production technology of cold rolling mills has been greatly improved. With the development of advanced technology, the design of cold rolling mills is gradually optimized. The structural design is continuously optimized, the parameters are adjusted and upgraded, the production efficiency and product quality are improved, and the energy consumption is greatly reduced.
Second, the construction technology has been further improved. Chinas cold rolling mills can now produce a variety of products with different specifications, parameters, designs and capabilities. As for materials, many Cold Rolling Mills are now made of stainless steel and other high-strength and high-temperature resistant materials.
Third, supporting and detection technology have been greatly developed. In the process of Rolling production, supporting devices and process test instruments have been greatly improved, and the digital, intelligent and autonomous control technology of Cold Rolling has also been applied. The wire-straightening technology and reel-slitting technology have also been continuously improved.
Finally, the automatic production process has been further optimized. Automated production and continuous production technology have been widely used, and the automation level has been further improved. In the process of automatic production, the entire production line operates efficiently and the rolling process is reliable. This has greatly improved the productivity and efficiency.
At present, Chinese cold roll mills have been widely used in automotive, aviation, electronics, and other industries, and have become a powerful engine for the development of the automobile, aviation and other industries. The cold roll mills have also made great contributions to the progress of other related industries and the realization of industrialization.
In the future, Chinas cold rolling production technology will continue to improve, and its applications will become more and more extensive. With the continuous popularity of low-carbon and energy-saving lifestyle, green and environmental protection Cold Rolling mills will be widely used in many fields. With the application of new technologies such as big data and artificial intelligence, the intelligence level and production efficiency of Cold Rolling mills will be greatly improved. Although it is still difficult to completely replace traditional cold rolling machines, the application of new technologies will bring quantitative changes to cold rolling production and management intelligent operation. In addition, the development of renewable energy will also drive the development of cold rolling technology.
In summary, although Chinas cold rolling production technology still has a long way to go compared with advanced foreign countries, it has also achieved remarkable results in recent years. It is believed that with the continuous progress of technology, large-scale equipment development, and continuous innovation and reform of Chinas cold Rolling Mills, the development of cold Rolling Mills will usher in a brand new era.
