The development of high-speed wire rod mills started with the improvement of finishing mill and controlled cooling technology. The high-speed rolling mill has been widely used in the transformation of small and wire rolling mills since its mature production technology. This is because the non-twist finishing mill is superior to the tandem rolling mill in both production efficiency and product quality, and even in the lower speed range, it is superior to the tandem rolling mill.
Usually, the technological characteristics of high-speed wire rolling mill can be summarized as continuous, high-speed, non-twist and air-cooling, among which high-speed rolling is the most important one.
The product characteristics of high-speed wire rod mills are the excellent performance of large plate weight and high precision.
Significance of High-Speed Rolling
After a breakthrough in the rolling speed of high-speed wire rod mills, people are still pursuing higher rolling speed. Because the rolling speed is high, the production efficiency is high and the cost is low, so the speed is the benefit.
Non-twist Finish Rolling is the Precondition to Ensure High-speed Rolling
The high-speed non-twist finishing rolling process is one of the core technologies in modern wire rod rolling mil production.
It is an effective means to solve the problems existing in various wire rod rolling mills in the past, and comprehensively solve the problems of product specifications, high section size accuracy, large plate weight, and high productivity. Only high finishing speed can have high productivity and solve the problem of temperature drop in the heavy wire rolling process. The high speed of finish rolling requires that there is no torsion in the rolling process.
Otherwise, rolling accidents occur frequently in the rolling processing and rolling cannot be carried out at all.
Therefore, the high-speed non-twist finish rolling is a basic feature of modern high-speed wire rod mills.
