Embodiment Construction

[0045] In order to further illustrate the technical solution of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0046] In the walking beam coil tracking method of the cold rolling treatment line implemented according to the present invention, the typical operating model of the walking beam is as follows: figure 1 Shown: wherein the walking beam movement steps are: 1. At the rear limit, rise from the lower limit to the upper limit. 2. At the upper limit, proceed from the rear limit to the front limit. 3. At the front limit, descend from the upper limit to the lower limit. 4. At the lower limit, back off from the front limit to the rear limit.

[0047] The following is combined with the specific implementation method of 3# walking beam steel coil material tracking at the exit of a continuous leveling line in a steel factory figure 1 To illustrate the present invention.

[0048] This production line adopts hie...

Abstract

The invention relates to a cold rolling processing line stepping beam steel coil tracking method. The method comprises the following steps of step1, setting a shared memory and setting an initial value of the shared memory; step2, carrying out parameter configuration on a stepping beam and storing the parameter configurations; and step3, tracking a steel coil on the stepping beam: S1, reading theparameter configurations in the step2; S2, according to a set frequency, periodically acquiring a real-time horizontal position and a vertical position of the stepping beam; S3, then comparing the real-time horizontal position and the vertical position of the stepping beam with the parameter configurations respectively, and determining a current state of the stepping beam; and S4, and then carrying out stepping determination. In the method, when one grade adopts a non-automatic (semi-automatic and manual) mode, or a proximity switch signal is not stable because of equipment shaking, phenomenaof a steel coil tracking error or missing and the like are not generated. The tracking method is completed under a PC platform and is not completed in a PLC system so that programming is simple and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of steel coil material tracking, in particular to a walking beam steel coil tracking method of a cold rolling processing line. Background technique [0002] Cold rolling treatment lines include continuous cold rolling production lines, pickling production lines, continuous annealing production lines, continuous tempering production lines, etc. Walking beams are placed at the entrance and exit of these production lines to buffer coils and increase production efficiency. Completing the correct tracking of steel coils on the walking beam is one of the necessary conditions to ensure the normal production of steel coils. [0003] The control system of the cold rolling processing line generally adopts hierarchical control. The first level is the basic automation system, and the second level is the process control system. For the process control system, on the walking beam, there are width, diameter, and weight ...
