AI Technical Summary
In the existing technology, the segmented quenching process of continuous heat treatment of hot-rolled steel coils lacks a mature automatic control method, which makes it impossible to dynamically adjust the cooling parameters and affects the stability of product performance.
A mist-water mixed quenching cooling device is adopted, which combines segmented quenching process setting calculation, feedforward control and post-calculation learning. By using water cooling, mist cooling and air cooling in different cooling zones, and using target and measured temperatures for dynamic adjustment, the automatic control of the segmented quenching process is realized.
It achieves uniform and rapid quenching of hot-rolled steel coils, ensuring stable product performance and meeting the cooling requirements of steel coils of different specifications.
