Feeding control device and control method for cross-over rolling-up unit

Abstract

The invention discloses a feeding control device and a feeding control method for a crossing coil upender unit, and belongs to the technical field of steelmaking equipment manufacturing, the device comprises a first detector, a second detector, a third detector and a monitor which are connected with a PLC, when a steel coil is placed on a saddle, the PLC receives distance information detected by the first detector and makes a judgment, and when the steel coil is placed on the saddle, the PLC sends the distance information to the controller; therefore, the alarm and the operation of the entrance stepping beam are controlled; when the steel coil is conveyed to the coil receiving saddle, the PLC receives information, detected by the second detector, about whether the steel coil exists or not, receives information, detected by the third detector, about whether the rolled edge of the steel coil is attached to the coil receiving face of the coil upender or not at the same time, and controls the stepping beam driver to enable the stepping beam to operate when the steel coil exists or is attached to the coil receiving face of the coil upender. According to the invention, the problem that the steel coil falls off due to difficulty in judging whether the center of the steel coil is aligned with the center of the saddle or not and whether the overflow edge of the steel coil is out of tolerance or not when the steel coil enters the coil receiving saddle of the coil upender during feeding of the cross coil upender unit can be solved.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment manufacturing, in particular to a material feeding control device and a control method for a cross-over turning unit. Background technique [0002] In the full-process cold rolling production process of iron and steel manufacturing enterprises, the horizontal steel coil output from the pickling tandem mill needs to pass through the cross-rolling unit to convert the horizontal steel coil to vertical for stacking and loading before it can enter the next hood annealing process. The existing cross-span rolling unit includes an entrance walking beam, an exit walking beam, a rolling machine base plate and a roll machine laterally arranged on the rolling machine base plate. One side of the machine is laterally extended, the exit walking beam is located at the rear end of the turning machine, and extends laterally from the other side of the base plate of the turning machine. The saddle of ...

Problems solved by technology

[0003] The invention provides a feeding control device and control method for a cross-span turning unit. The device and method can solve the problem that it is difficult to judge whether the center of the steel coil is aligned with the center of the saddle and whether the steel coil enters the turning process when the cross-span turning unit is feeding. Whether the overflow edge of the machine's coil receiving saddle is out of tolerance, which will eventually lead to the problem of steel coil falling
