Abstract
The present invention relates to hot rolling technique field, particularly a kind of control method of hot rolled plate template.Described method comprises: value roller value being arranged to one group of mechanical periodicity in hot rolled plate plate form control system, and hot rolled plate Controlling model determines one group of string roller value changed according to roller value; Using roller value and string roller value as the control data of hot rolled plate plate form control system, realize the control to hot rolled plate template.The control method of hot rolled plate template provided by the invention, makes the step-length adjusting range of string roller comparatively large, solves the problem of the hot rolled plate local eminence caused because roll shifting step-length adjusting range is little.
Description
Technical field
The present invention relates to hot rolling technique field, particularly a kind of control method of hot rolled plate template.
Background technology
Hot rolled plate is conventional industrial materials, the hot rolled plate plate form control system that current iron and steel enterprise comparatively commonly uses mainly contains the PCFC plate form control system of SMS company and the PFC plate form control system of TMEIC company, the common feature of these systems is mm finishing mill unit all or part of use CVC shape of working roll, roller control strategy adopts fixed value mode, in plate form control system, set a changeless roller value, then automatically calculate a changeless string roller value by plate form control system.Because string roller value is invariable, therefore the roll shifting step-length adjusting range produced under this kind of control strategy is little causes hot-rolled product local eminence, and roll roll shifting space availability ratio low causing shifts to an earlier date roll change, 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 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: value roller value being arranged to one group of mechanical periodicity in hot rolled plate plate form control system, hot rolled plate Controlling model determines one group of string roller value changed according to roller value; Using described roller value and string roller value as the control data of described hot rolled plate plate form control system, realize the control to hot rolled plate template.
Described roller value is by sinusoidal wave or sawtooth waveforms rule change.
The span of described roller value is 200KN-1400KN.
The control method of hot rolled plate template provided by the invention, the roller value of mechanical periodicity is pressed to hot rolled plate plate form control Operation system setting one group, hot rolled plate plate form control system determines one group of string roller value changed simultaneously, make the step-length adjusting range of string roller comparatively large, solve the problem of the hot rolled plate local eminence caused because roll shifting step-length adjusting range is little.
Accompanying drawing explanation
The Control system architecture schematic diagram of the hot rolled plate template that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
The control method of the hot rolled plate template that the embodiment of the present invention provides and system, realize under CVC shape of working roll control model based on hot rolled plate plate form control system (as PCFC plate form control system or PFC plate form control system).Hot rolled plate plate form control system based on 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, be handed down to executing agency to perform, and according to the measured value of glacing flatness instrument and convexity instrument, Continuous optimization controling parameters, realizes closed-loop control, belongs to known technology.In controlling hot rolling field, hot rolled plate plate form control system can determine string roller value accordingly according to the roller value of setting, and roller value, string roller value are the significant datas controlling hot rolled plate template.The control method of the hot rolled plate template that the embodiment of the present invention provides by optimizing the data of roller value and string roller value in controlling hot rolling process, thus controls hot rolled plate template, specifically comprises:
Roller value is arranged to the value of one group of mechanical periodicity in hot rolled plate plate form control system, hot rolled plate Controlling model determines one group of string roller value changed according to roller value.Wherein, roller value presses the change of sawtooth waveforms or sine wave period, and the span of roller value is 200KN-1400KN (as 200KN, 800KN or 1400KN), namely in the process of roller value change, roller value is minimum can not lower than 200KN, and roller value is maximum can not higher than 1400KN.
Using roller value and string roller value as the control data of hot rolled plate plate form control system, realize the control to hot rolled plate template.
See Fig. 1, the embodiment of the present invention additionally provides a kind of control system of hot rolled plate template, comprise: data setting unit, for roller value being arranged to the value of one group of mechanical periodicity in hot rolled plate plate form control system, specifically comprise the period of change of roller value, maximum and minimum of a value data, hot rolled plate plate form control system is calculated string roller value; Data determination unit, for the roller value arranged according to data setting unit, determines one group of string roller value changed; Control unit, the string roller value determined for the roller value that arranged by data setting unit and data determination unit, as the control data of hot rolled plate plate form control system, realizes the control to hot rolled plate template.
The control method of hot rolled plate template provided by the invention, the little problem causing hot-rolled product local eminence of roll shifting step-length adjusting range produced under solving conventional roll system arrangement and control strategy, the roll shifting step-length of every block hot rolled plate is strengthened, be increased to present 8-10mm by original 3-5mm, greatly reduce therefore and produce template edge protuberance quality problems.Meanwhile, add roll roll shifting space availability ratio, extend the Rolling roller phase, make roll shifting utilization rate be increased to present 120mm by original average 80mm, roller phase length extends to present 100 pieces by original 80 pieces.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
