The method comprises the following steps: setting the roll bending value to a group of periodically changed values in a hot rolled plate profile control system, and determining a group of changed string roll values by a hot rolled plate control model according to the roll bending value; and the roll bending value and the roll string value are used as control data of a hot rolled plate profile control system to realize the control of the hot rolled plate profile. The system comprises: the device comprises a data setting unit, a data determining unit and a control unit. The method and the system for controlling the plate type of the hot rolled plate enable the step length adjustment amplitude of the roller string to be large, and solve the problem of local bulging of the hot rolled plate caused by small adjustment amplitude of the roller shifting step length.
Description
Technical field
The present invention relates to the hot rolling technical field, particularly a kind of control method of hot rolled plate template and system.
Background technology
Hot rolled plate is industrial materials commonly used, iron and steel enterprise's hot rolled plate template control system comparatively commonly used mainly contains the PCFC template control system of SMS company and the PFC template control system of TMEIC company at present, the common feature of these systems is all or part of use of mm finishing mill unit CVC shape of working roll, the roller control strategy adopts the fixed value mode, set a changeless roller value in the template control system, then by the template control system, automatically calculate a changeless string roller value.Because string roller value is invariable, therefore the roll shifting step-length adjusting range produced under this kind of control strategy is little causes the hot-rolled product local eminence, and roll roll shifting space availability ratio is low causes roll change in advance, these will affect template quality and the production efficiency of hot-rolled product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hot rolled plate method for controlling shape and system that can solve hot rolled plate local eminence problem.
For solving the problems of the technologies described above, the invention provides a kind of hot rolled plate method for controlling shape, comprising: the roller value is arranged to the value that one group of cycle changes in hot rolled plate template control system, hot rolled plate is controlled model and is determined one group of string roller value changed according to the roller value; Using described roller value and string roller value as the control data of described hot rolled plate template control system, realize the control to the hot rolled plate template.
Described roller value presses sine wave or the sawtooth waveforms rule changes.
The span of described roller value is 200KN-1400KN.
The present invention also provides a kind of control system of hot rolled plate template, comprising:
The data setting unit, in hot rolled plate template control system, the roller value being arranged to the value that one group of cycle changes, specifically comprise period of change, maximum and the minimum of a value data of roller value;
The data determining unit, for the roller value arranged according to described data setting unit, determine one group of string roller value changed;
Control module, as the control data of described hot rolled plate template control system, realize the control to the hot rolled plate template for roller value that described data setting unit is arranged and the definite string roller value of data determining unit.
The control method of hot rolled plate template provided by the invention and system, give hot rolled plate template set-up of control system one group of roller value changed by the cycle, hot rolled plate template control system is determined one group of string roller value changed simultaneously, make the step-length adjusting range of string roller larger, solved the problem because of the little hot rolled plate local eminence caused of roll shifting step-length adjusting range.
The accompanying drawing explanation
The control system structural representation of the hot rolled plate template that Fig. 1 provides for the embodiment of the present invention.
The specific embodiment
Control method and the system of the hot rolled plate template that the embodiment of the present invention provides, be based on hot rolled plate template control system (as PCFC template control system or PFC template control system) and realize under CVC shape of working roll control model.Hot rolled plate template control system based on the CVC working roll comprises template computation model, executing agency's (as roller, roll shifting system), glacing flatness instrument and convexity instrument, its control flow is: according to the Target Board offset of product and the feature of CVC continuous variable roll forming, model calculates roller value and roll shifting value, being handed down to executing agency carries out, and according to the measured value of glacing flatness instrument and convexity instrument, Continuous optimization is controlled parameter, realizes closed-loop control, belongs to known technology.In the controlling hot rolling field, hot rolled plate template control system can be determined string roller value accordingly according to the roller value of setting, and roller value, string roller value are to control the significant data of hot rolled plate template.The control method of the hot rolled plate template that the embodiment of the present invention provides is by optimizing the data of roller value and string roller value in the controlling hot rolling process, thereby the hot rolled plate template is controlled, and specifically comprises:
The roller value is arranged to the value that one group of cycle changes in hot rolled plate template control system, hot rolled plate is controlled model and is determined one group of string roller value changed according to the roller value.Wherein, the roller value is pressed the variation of sawtooth waveforms or sine wave period, and the span of roller value is that 200KN-1400KN(is as 200KN, 800KN or 1400KN), in the process changed in the roller value, roller value minimum can not be lower than 200KN, and roller value maximum can not be higher than 1400KN.
Using roller value and string roller value as the control data of hot rolled plate template control system, realize the control to the hot rolled plate template.
Referring to Fig. 1, the embodiment of the present invention also provides a kind of control method and system of hot rolled plate template, comprise: the data setting unit, for in hot rolled plate template control system, the roller value being arranged to the value that one group of cycle changes, the period of change, maximum and the minimum of a value data that specifically comprise the roller value, can be calculated to string roller value hot rolled plate template control system; The data determining unit, for the roller value arranged according to the data setting unit, determine one group of string roller value changed; Control module, as the control data of hot rolled plate template control system, realize the control to the hot rolled plate template for roller value that the data setting unit is arranged and the definite string roller value of data determining unit.
The control method of hot rolled plate template provided by the invention and system, solved the little problem that causes the hot-rolled product local eminence of roll shifting step-length adjusting range produced under conventional roll system arrangement and control strategy, the roll shifting step-length of every hot rolled plate is strengthened, be increased to present 8-10mm by original 3-5mm, greatly reduced therefore and the template limit section produced protuberance quality problems.Simultaneously, increased roll roll shifting space availability ratio, extended the Rolling roller phase, made the roll shifting utilization rate be increased to present 120mm by original average 80mm, roller phase length extends to present 100 by original 80.
It should be noted last that, the above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to example, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
