AI Technical Summary

Technical Problem

In the production of high-speed wires, it is difficult to control the head of the single-passing unit with reduced diameters, resulting in the smooth passage of the rolled parts under high speed and the product quality being affected, and it is difficult for the prior art to achieve efficient and accurate head control.

Method used

By setting a detector between the upstream rolling mill and the downstream rolling mill, the initial speed, inlet time and forward slip value of the rolling piece are obtained, and the passing time is used to calculate the time when the rolling piece reaches the downstream rolling mill entrance, and the head speed is reduced at this time, and an arc-shaped speed down curve is used to achieve precise control.

Benefits of technology

Accurate control of the speed drop of the rolled head is achieved, equipment utilization rate is improved, fault downtime is reduced, and product quality and economic benefits are improved.

Abstract

The embodiment of the invention provides a method and system for controlling the speed of a rolling mill. The method comprises the steps that a target rolled piece sequentially penetrates through an upstream rolling mill, a detector and a downstream rolling mill; the initial speed and the initial inlet moment when the target rolled piece reaches a detector, the forward slip value of the target rolled piece passing through an upstream rolling mill and the first distance between the detector and a downstream rolling mill are obtained; according to the initial speed, the first distance and the initial forward slip value, the first passing time of the target rolled piece passing through the detector and the first rolling mill is obtained; according to the initial inlet moment and the first passing time, the first inlet moment when the target rolled piece reaches a downstream rolling mill inlet is obtained; and head speed reduction is conducted on the target rolled piece at the first inlet moment when the target rolled piece reaches a downstream rolling mill inlet. According to the method, the opportunity and amplitude of head prompt drop are accurately controlled.
