The various devices and the like used in the present invention are commercially available or can be prepared by existing methods unless otherwise specifically indicated.
In order to solve the problems that coil tracking information in the coil unloading process is not eliminated timely and continuous and stable production of a hot rolling production line is affected, the invention provides a method for clearing coil tracking information of a coiling machine, wherein the coiling machine comprises N auxiliary coiling rollers, N is more than or equal to 2 and is an integer, and the whole idea is as follows:
obtaining the maximum thickness of a hot rolled coil which can be produced by a current hot rolling production unit; during the coil unloading process of the coiling machine, obtaining the roll gap values of the coil assisting rolls of the N coil assisting rolls; and if the roll gap values of the N auxiliary winding rolls are smaller than the maximum thickness of the hot rolled coil, clearing the coil tracking information of the coiling machine.
The principle of the cleaning method is as follows: judging whether a plate coil actually exists in the coiling machine according to the roll gap values of all the auxiliary coiling rollers of the coiling machine in the coil unloading process of the coiling machine; because the roll gap of the auxiliary roll is the distance from the auxiliary roll to the winding drum, when all roll gap values of the auxiliary rolls are smaller than the maximum thickness of the hot rolled plate roll, the fact that the winding drum of the winding machine has no winding plate roll at the moment is indicated, all the auxiliary rolls are closed, and the plate roll tracking information in the winding machine is forcedly cleared at the moment, so that the winding machine has the regeneration capacity; according to the method, whether the auxiliary roll is closed or not is judged through the roll gap value of the auxiliary roll, whether the plate roll leaves the coiling machine or not is further determined, and the plate roll tracking information is cleared. By timely clearing the plate coil tracking information, the coiling machine can quickly recover the production capacity again, and the phenomenon that the continuous production rhythm of endless rolling is affected due to stagnation or coil stacking in plate coil production is avoided.
According to the above inventive concept, in the following alternative embodiment, as shown in fig. 1, the above method is applied to a control system of a coiler for hot rolled strip, and after knowing the control logic of strip coiling, a person skilled in the art can multiplex the strip into a coil process requiring hot rolling production, such as titanium coils, aluminum coils, etc.
S1: obtaining the maximum thickness of the hot rolled steel coil which can be produced by the current hot rolling production unit;
the maximum thickness of the hot rolled steel coil is the maximum strip rolling capacity of the current hot rolling unit and can be predetermined from a design manual of the unit. The thickness of the hot rolled coil is typically a maximum of 15 to 25 mm, depending on the specifications of the hot continuous rolling train with coiling.
S2: during the coil unloading process of the coiling machine, obtaining the roll gap values of the coil assisting rolls of the N coil assisting rolls;
the hot rolling coiling machine is positioned behind the hot continuous rolling finishing mill group and is the last procedure of the hot continuous rolling production line. Typically, a plurality of auxiliary winding rollers, typically 3 or 4, are provided on the coiler. The function of the auxiliary winding roller is to help bend the strip and to tightly wind the strip around the reel. The gap value or distance value between the auxiliary roller and the winding drum is called an auxiliary roller gap value, and the auxiliary roller gap is controlled by an auxiliary roller oil cylinder.
The method for judging whether the coiling machine is in the coil unloading process is as follows:
receiving a coil unloading signal for controlling the coil unloading trolley to unload coils;
and determining that the coiling machine enters a coil unloading process according to the coil unloading signal.
Specifically, when the hot rolled strip steel is coiled, when the steel coil on the winding drum reaches a set length, the coiling machine starts to throw the tail until the tail is positioned at a fixed position on the section of the winding drum of the coiling machine, at the moment, the coiling machine stops running, and simultaneously, a coil unloading signal is triggered, and a control system controls the coil unloading trolley to automatically unload coils.
S3: and if the roll gap values of the N auxiliary winding rolls are smaller than the maximum thickness value of the hot rolled steel coil, clearing the steel coil tracking information of the coiling machine.
When the roll gap values of all the auxiliary rolls are all smaller than the maximum thickness value of the hot rolled steel coil, the fact that no steel coil exists in the winding drum of the coiling machine is indicated, and all the auxiliary rolls are closed is forced to clear the current recorded steel coil tracking information of the coiling machine. The steel coil tracking information comprises the information of the number of the coiled steel coil, the width of the strip steel, the thickness of the strip steel, the theoretical coil weight, the theoretical coil diameter and the like.
After the coil tracking information of the coil steel is cleared, the current coiling machine has the capacity of producing again, the scheme is temporarily stopped, and after the coiling of the next coil steel is completed and a coil unloading signal is triggered, the method starts to detect the coil assisting roller gap values of the N coil assisting rollers again. The control is to avoid that the proposal is not triggered if the roll gap of the auxiliary roll meets the judgment condition at the moment of non-coil unloading, and avoid that the tracking information of the steel coil is erroneously cleared and control accidents are generated.
By the method, the effective removal of the coil tracking information in the coiling machine is ensured, the problem that the conventional method for removing the coil tracking information in the coiling machine fails is avoided, the coiling machine is further ensured to be capable of timely and again having coiling production conditions, the occurrence of coiling steel stacking accidents is avoided, and the continuous and stable operation of the headless production line can be realized.
In order to more intuitively illustrate the above method, in one embodiment, the following describes the above method with reference to specific implementation data:
step 1: during the coiling process of the rolled strip steel, firstly judging whether the coiling machine is in the coil unloading process, and starting the step 2 when judging that the coiling machine is in the coil unloading process;
step 2: judging the closing condition of all the auxiliary rolls, namely logically judging the roll gap condition of all the auxiliary rolls, wherein the coiling machine is provided with 4 auxiliary rolls, and the roll gap values of the 4 auxiliary rolls are as follows: GAP1 actual=3 mm, GAP2 actual=2.5 mm, GAP3 actual=2.2 mm, GAP4 actual=2.0 mm, all the above-mentioned auxiliary roll GAP values are smaller than 15mm,15mm is the maximum rolling thickness of the hot rolled sheet coil that can be produced by the current hot rolling mill;
step 3: and 2, judging that no real steel coil exists in the coiling machine, so that the current steel coil tracking information is forcedly cleared. Returning again to step S1, these steps are repeated until the rolling is completed.
A control process diagram of the above process is shown in fig. 2.
In some alternative embodiments, if the obtaining of the roll gap value of the auxiliary roll is blocked, in order to avoid the problem that the tracking information of the steel coil cannot be cleared caused by this situation, the method also maintains the original control logic, namely: receiving a coil unloading completion signal of a coil unloading trolley; and clearing the plate coil tracking information of the coiling machine according to the coil unloading completion signal of the coil unloading trolley.
In some alternative embodiments, in order to inform the technician in the working area in time that the coiler clears the coil tracking information of the current coil, the clearing method further includes:
generating reminding information of which the plate coil tracking information is cleared;
and sending the reminding information to a human-machine interaction HMI picture of the coiler control system.
In yet another alternative embodiment, as shown in fig. 3, there is provided a device for clearing tracking information of a coiler plate roll, the coiler including N auxiliary winding rollers, N being equal to or greater than 2 and being an integer, the device comprising:
an obtaining module 10, configured to obtain a maximum thickness of a hot rolled coil that can be produced by the current hot rolling production unit; during the coil unloading process of the coiling machine, obtaining the roll gap values of the auxiliary coil rollers of the N auxiliary coil rollers;
and the clearing module 20 is used for clearing coil tracking information of the coiling machine if the roll gap values of the N auxiliary coils are smaller than the maximum thickness value of the hot rolled coil.

and the determining module 02 is used for determining that the coiling machine enters a coil unloading process according to the coil unloading signal.
