AI Technical Summary

Technical Problem

The pre-set buffer of existing winding computers results in low winding efficiency, which limits the hot strip rolling speed.

Method used

A head and tail tracking module and a dual-steel online buffer are constructed. The sensor and winding computer are connected through a microprocessor. The winding computer buffer is split into BO1 and BO2 to track the head and tail position data of the two steel pieces and send control parameters to the winding machine according to the strip logic on site.

Benefits of technology

It improved the coiling rhythm of the coiler, enhanced the stability of the overall rolling rhythm of the hot continuous rolling mill, solved the problem of flashing malfunction in the hot inspection, and realized the simultaneous online control of two steel pieces.

Abstract

This invention relates to a control method for simultaneous online coiling of two steel sections in hot continuous rolling, comprising the following steps: S1, constructing a head-tail tracking module and a simultaneous online buffer for the two steel sections; S2, the head-tail tracking module tracks the head-tail position data of each of the two rolled sections when they are simultaneously online, and sends the head-tail position data to the coiling computer; S3, the process machine receives the coiling machine function selection, and sends the actual control parameters to the simultaneous online buffer for the two steel sections according to the coiling machine function selection; the coiling computer sends the actual control parameters to the coiling machine according to the on-site strip logic. This solution solves the problem of flashing malfunction in hot strip inspection, enhances the stability of the system, thereby meeting the control requirements for online coiling of two steel sections, improving the coiling rhythm of the coiling machine, and thus improving the overall rolling rhythm of hot continuous rolling.
