Embodiment 1
[0024] figure 1 It is a schematic flowchart of an automatic reversing method for cold-rolled plates in an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0025] Step 110: Obtain a first instruction, where the first instruction is used to instruct automatic reverse.
[0026] Specifically, the first instruction refers to the program of starting to execute the command in order to complete the automatic reversing function, that is to say, when the plate needs to eliminate acid spots and rust in the pickling stage, first, the human-machine interface HMI (Human machineinterface) and click the automatic reverse button, at this point, the program can obtain the first instruction and turn on the automatic reverse function.
[0027] Step 120: Close the inlet and outlet of the pickling tank according to the first instruction.
[0028] Specifically, after the program obtains the first instruction, that is, after starting to execute the automatic ...

Abstract
The invention discloses an automatic backing-up method of cold-rolled sheet material, and relates to the technical field of steel rolling. The method comprises the steps that a first instruction is obtained and is used for instructing automatic backing-up; an outlet and an inlet of an acid washing tank are closed according to the first instruction; a wringing roller of a rinsing tank is closed according to the first instruction; an uncoiling centering system is switched to an intermediate mode according to the first instruction; and an air purging valve located at a withdrawing and straightening machine is opened according to the first instruction; a second instruction for automatic backing-up is performed, wherein according to the second instruction, automatic backing-up is carried out ata first speed for a first predetermined distance; a third instruction for lathe stopping is performed, wherein according to the third instruction, a lathe is stopped for a first time; and a fourth instruction for automatic advancing is performed, wherein according to the fourth instruction, automatic advancing is carried out at a second speed for a second predetermined distance. By means of the automatic backing-up method of the cold-rolled sheet material, the problems that in the prior art, backing-up is complex, equipment is complicated to restore when generating an alarm or breaking down are solved, so that the technical effects of eliminating acid spots and rust on the surface of the sheet material, improving the yield, saving time and labor, and being safe and rapid are achieved.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to an automatic reversing method for cold-rolled plates. Background technique [0002] In the field of steel rolling technology, with the continuous improvement of acid rolling output and energy saving and consumption reduction requirements, the requirements for yield indicators are also getting higher and higher. However, acid spots and corrosion will appear on the steel strip in the pickling and rinsing sections after maintenance or long-term shutdown. Therefore, after starting the machine, the trimming and shearing operator will mark the defects on the strip steel, and the defective strip steel will pass through the rolling mill at a slow speed. Become a waste roll, thus causing a lot of waste and such waste is inevitable. In the prior art, after the pickling section is parked for a long time or before starting after maintenance, the operator will track on the spot and man...
