According to the invention, a computer readable storage medium is provided, in which a computer program is stored, and the computer program is executed by a processor to realize the steps of the visual continuous annealing furnace roller automatic grinding method.
The invention discloses a furnace roller automatic grinding technology of a heating furnace section of a continuous annealing unit, which adopts a newly-added furnace roller automatic grinding control ring in a basic automatic PLC (programmable logic controller) to control, and artificially increases the friction between a furnace roller and strip steel to grind and level a nodulation area under the condition of serious furnace roller nodulation, thereby reducing the influence of pockmarks on the surface of the strip steel.
The 'furnace roller automatic coping' control ring comprises the following steps:
1. interface for increasing grinding compensation speed
Because the ASR (speed control ring) + ATR (tension control ring) in the basic automation PLC, the control quantity of furnace rollers of each furnace section is the same, in order to increase the friction between a specific furnace roller and the strip steel, a 'coping compensation speed' delta V needs to be increased, and finally the output control speed of the furnace roller is changed into ASR + ATR + delta V (see a chart 2);
2. augmenting a visual interface
An interface for selecting a grinding furnace section and inputting and stopping a grinding function is added in an HMI (human-machine operation interface), so that an operator can flexibly select a corresponding area when a nodule occurs;
the furnace roller entering the grinding state is added with the display of the grinding state and the record of the grinding time on the HMI, so that an operator can know the grinding state in time and analyze the grinding effect (see a chart 3).
3. Automatic grinding control process of furnace roller (see figure 4)
If the friction duration between the furnace roller and the strip steel is too long, the surface of the strip steel can be scratched, so that two timers T1 and T2 and a counter C1 are arranged in the automatic furnace roller grinding procedure, and when the T1 timer is activated, the furnace roller enters a grinding state; when the T1 timer is finished and the T2 timer is activated, the furnace roller finishes the grinding state; when the T2 timer is over, triggering the counter C1, recording as a thinning combination, then activating the timer T1 again, and circularly counting; the maximum value N of the counter C1 is determined according to the number of furnace rollers in the furnace section, and when the thinning combination count reaches the preset maximum value N, the counter C1 is reset to 0.
When the timers T1, T2 and the counter C1 work normally, the grinding sequence of the actual furnace roller can be flexibly distributed according to the requirement. For example, when the maximum value N of the counter is the number N of furnace rollers in the furnace section (that is, N is equal to N), C1 is only required to be equal to 1, the furnace roller No. 1 is activated in the thinning state, C1 is equal to 2, the furnace roller No. 2 is activated in the thinning state, and so on. When the grinding frequency needs to be increased, N is equal to N/m, and if m is equal to 2, C1 is required to be equal to 1, No. 1 and No. 2 furnace rollers activate the grinding state, and when C1 is equal to 2, No. 3 and No. 4 activate the grinding state, and so on, at this moment, the grinding frequency of the furnace section is doubled.
4. Generating a sharpening compensation speed
In order to balance between smoothing the nodulation area and avoiding scratching, a set of coping compensation speed based on the actual running speed of the unit needs to be customized. An array F10 containing 10 elements is set in the program, ten fluctuating random speed factors are stored, when the furnace roller is selected to activate the grinding state for the 1 st time, the furnace roller is Delta V-F1 (ASR + ATR), when the furnace roller is selected to activate the grinding state for the nth time, the furnace roller is Delta V-F n (ASR + ATR), and the final effect is that the selected furnace roller generates a random tiny speed difference with other furnace rollers in the section periodically, and the nodulation area is ground rapidly and slowly.
A stopping step: and clicking a stop button on an HMI (human machine interface) for starting polishing, immediately stopping all polishing programs, and recovering to normal production logic.
Example 1: in a furnace section control program of a Zhanjiang 2030mm cold rolling continuous annealing unit, after the automatic grinding control program of the furnace roller is added, the pockmark area is reduced by 20 percent compared with that before the furnace roller is added;
example 2: in a furnace section control program of a Zhanjiang 1550mm cold rolling continuous annealing unit, an automatic grinding control program of the furnace roller is added, and the pitting area is reduced by 25% compared with that before the rolling process is put into practice.
