High-speed line material without-groove rolling technology is a new technology that uses non-groove non-roller blanking technology to hot roll thick and ultra thin steel strips. This kind of technology provides a solution to the thickness reduction, powder metallurgy and rolling difficulties in the hot rolling of steel strips, and effectively solves the problems of production efficiency, material utilization and product quality of ultra-thin steel strips.
The application of high-speed line material without-groove rolling technology has made it possible to reduce the thickness of steels, to improve raw material utilization, to improve product yield, to reduce production costs and to reduce energy consumption. The application of high-speed line material without-groove rolling technology is mainly used in the production of high-strength cold-rolled steel strips and stainless steel strips. It is expected to develop further in the future.
1.Application and development of high-speed line material without-groove rolling technology
The application of high-speed line material without-groove rolling technology can improve the product quality, reduce the manufacture cost and make the production efficiency increase. At present, this technology has been applied in cooperating with segmented type of large-volume rough rolling mill, as well as medium and thin steel belt production lines. With the development of steel rolling technology, the application of high-speed line material without-groove rolling technology is also expanding.
At present, domestic high-speed line material without-groove rolling technology is mainly used in the production of high-strength cold-rolled steel strips and special steel strips. This technology is characterized by high-precision roll gap control, small roll gap change and low weft quantity fluctuation. The application of high-speed line material without-groove rolling technology in the production of stainless steel strips has achieved satisfactory product quality. It can be seen that the application of high-speed line material without-groove rolling technology has a bright prospect in the field of thin steel strip hot rolling.
In addition, there are some special requirements for high-speed line material without-groove rolling when applied to thin steel strip hot rolling. First of all, the spindle and milling machine need to be designed to meet the requirements of thin rolling, so as to ensure the stability of thin rolling. Secondly, the rolling gap needs to be controlled accurately, the roll gap should not be too large and the roll gap change should be minimized. Thirdly, the rolling speed should be suitable and the hot rolling process should be stable.
2. Advantages of high-speed line material without-groove rolling technology
High-speed line material without-groove rolling technology has the advantages of high production efficiency, high raw material utilization, low cost and high product yield. The product thickness used in the process of high-speed line material without-groove rolling technology is more uniform, which makes the product surface more smooth and level. The application of high-speed line material without-groove rolling technology can also improve the product tolerance and can produce high-precision products.
In addition, the production cost of high-speed line material without-groove rolling technology is lower than that of traditional rolling. The thickness accuracy and transverse direction straightness of the blank is high, so the waste of blank material is reduced. In the process of high-speed line material without-groove rolling technology, the friction between roller and material is small, so the energy consumption is low. The control system can adjust the rolling parameters automatically, which is convenient and efficient.
3. Application prospect of high-speed line material without-groove rolling technology
High-speed line material without-groove rolling technology has great development prospects, and is widely used in the production of high-strength cold-rolled steel strips, ultra-thin stainless steel strips and special steel strips. In the future, the application of high-speed line material without-groove rolling technology can be further expanded and applied in more fields.
At present, the production of high-strength cold-rolled steel strips has developed rapidly, and the thickness of steel strips has decreased. With the increasing demand for ultra-thin steel strips, the application of high-speed line material without-groove rolling technology will be more and more in the production of ultra-thin steel strips.
Conclusion
In conclusion, high-speed line material without-groove rolling technology has many advantages and has a wide range of applications and great development prospects. This kind of rolling technology is applicable to the production of high-strength and ultra-thin steel strips. With its unique advantages and good product quality, it is widely used in various fields, and its application prospects are bright.
