Long-distance-leaving steel billet positioning control system for roughing mill

Abstract

The invention discloses a steel running positioning control system for a blanking machine, which specifically includes: a roller table, an entrance turning machine, a blanking machine, an entrance push bed, an entrance hot metal detector, an exit hot metal detector, and an exit push bed; The entrance hot metal detector is connected with the roller table, and the speed of the roller table is controlled by the detected hot metal signal, so that the billet is decelerated on the roller table; the outlet hot metal detector is located on the rear working roller table of the entrance detector, It is connected with the blanking machine and the roller table, and is characterized in that the operation of the main motor roller table of the blanking machine is controlled by the loss of the steel bite signal of the blanking machine frame during the rolling process. Beneficial effects of the present invention: the design is simple and easy to implement; through the control of the rolling speed of the billet mill and the control of the operation mode of the roller table, the distance from which the billet rushes out of the rack of the billet mill can be precisely controlled; Control time, so as to achieve the purpose of speeding up the production rhythm, ensuring steel temperature and saving energy.

Description

technical field [0001] The invention relates to an optimal control design of a blanking machine running steel, in particular to a blanking machine running steel positioning control system. Background technique [0002] The blanking machine system is mainly composed of blanking machine frame, roll gap pressing device, entrance and exit pusher, turning groove, turning machine, entrance and exit roller table and other equipment. During the blanking process, the blanking machine requires relatively high accuracy for the position of the steel billet. In the production process of the workshop, when each piece of material is rolled for an odd number of times, the billet leaves the blanking machine frame, and the heat after passing through the frame The detection signal gives the roller table stop command. In actual production, relying on the heat detection signal after the roll to stop the program of the main motor and roller table of the blanking machine, when the exit roller tab...

AI Technical Summary

Problems solved by technology

In the back and forth rolling process, due to the billet running steel problem, the rolling time is long, which affects the billet opening progress and rolling rhythm, and then affects the temperature of the billet entering the continuous rolling entrance, which will have a greater impact on the process quality
