Head and tail recognition speed drop control system and control method for seismic reinforcement

Abstract

The embodiment of the invention relates to the technical field of steel bar rolling and particularly discloses an anti-shock steel bar end-end recognition prompt drop control system and control method. The anti-shock steel bar end-end recognition prompt drop control system disclosed by the invention comprises a PLC, a first detection device and a second detection device, wherein the first detection device and the second detection device are arranged on a furnace delivery roller bed between an outlet of a heating furnace and an inlet of a first rolling machine. The first detection device and the second detection device are in communication with the PLC correspondingly and transmit detected trigger signals to the PLC. The PLC is further in communication with a furnace delivery roller bed controller and a first rolling machine controller and transmits a control signal to the furnace delivery roller bed controller and the first rolling machine controller. The anti-shock steel bar end-end recognition prompt drop control system achieves the purpose of opening the end-to-end distance of steel billets and improves the yield of rolled steel bars.

Description

technical field [0001] The invention relates to the technical field of rolled steel bars, in particular to an anti-seismic steel bar head and tail identification speed drop control system and control method. Background technique [0002] When rolling steel bars in a bar factory, there must be a certain distance between the tail of the previous billet and the head of the next billet before they enter the first rolling mill in order to ensure the maximum production per machine hour. Due to the operator’s carelessness, the tail of the previous billet The rolling distance between the billets cannot be opened automatically if the head of the latter billet is not disconnected. [0003] Since there is no device for detecting the distance between billets on the roller table at present, when the billets are connected head-to-tail due to careless operation by the operator, the program cannot perform protection actions because the abnormality of the head-to-tail connection of the bille...

[0002] When rolling steel bars in a bar factory, there must be a certain distance between the tail of the previous billet and the head of the next billet before they enter the first rolling mill in order to ensure the maximum production per machine hour. Due to the operator’s carelessness, the tail of the previous billet The rolling distance between billets cannot be automatically opened if the head of the billet is not disconnected from the latter

[0003] Since there is no device for detecting the distance between billets on the roller table at present, when the billets are connected head-to-tail due to careless operation by the operator, the program cannot perform protection actions because the abnormality of the head-to-tail connection of the billets cannot be detected, resulting in flying shears on the rolling line. , loopers and other equipment cannot complete the set action, which eventually leads to rolling waste caused by rear-end collision of the rolled piece
