Description
Technical field
The present invention relates to bar production field, be specifically related to a kind of control system and method for producing online adjustment based on the full multiple length of Direct Rolling bar.
Background technology
In bar Direct Rolling production process, through the finished product length after rolling, much larger than charge length, therefore, must shear and can proceed to next procedure after segmentation and process finished product.At present, the equipment that finished product is carried out to nibbling shear mostly is multi-length shear, and adopting artificial each cutter sheared length of setting is multiple lengths.In actual production process, due to section difference, the charge length temperature fluctuation of the every stream of continuous casting billet, multiple lengths is fixed and the percentage elongation of products of different specifications different, in production, often occur that multi-length shear cuts short chi, cause scale rate not high, also affect lumber recovery simultaneously; In addition, the short chi that multi-length shear cuts rests in lower steel guide groove, and easy and next root bar bumps against, and occurs heap steel, causes cold bed fault, upsets rhythm of production, to operating personnel, brings danger.
Summary of the invention
The object of the invention is to address the above problem, provide a kind of and produce online control system and the method for adjusting based on the full multiple length of Direct Rolling bar, this system can solve heap steel and the upper cold bed failure problems causing due to short chi in bar production, guarantee production direct motion, improved to greatest extent scale rate and lumber recovery simultaneously.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of control system of producing online adjustment based on the full multiple length of Direct Rolling bar, comprise information process unit, and be connected with information process unit for gathering adjustment information and information feedack collector, on information process unit, be also connected with for controlling the motion of cutting machine and the cutter controller of cutting action; On cutter controller, be connected with for steel billet being cut into the cutting machine of specific length, the information exchange that information process unit gathers according to information acquisition device is crossed cutter controller control cutting machine and is carried out cutting action.
Described information process unit is the computer that stores the Mathematical Modeling of each specification rear length adjustment amount △ L and flame cutting machine cutting time delay adjustment amount △ S.
Described cutting machine is for steel billet being cut into the flame cutting machine of specific length.
Based on the full multiple length of Direct Rolling bar, produce an online control method of adjusting, comprise the following steps:
1) first, every stream caster base is gathered to the information of the rear length adjustment amount △ L of this on duty produced scale rod bar by information acquisition device, and be delivered to information process unit;
2) then, the information that information process unit gathers information acquisition device is carried out computing, obtains cutting machine time delay adjustment amount △ S, and cutting machine time delay adjustment amount △ S is delivered to cutter controller;
3) then, cutter controller sends instruction according to cutting machine time delay adjustment amount △ S to flame cutting machine, and every stream steel billet is positioned to cutting;
4) last, by information acquisition device, information or requirement after adjusting are fed back to information process unit, and storage.
Described step 2), in, cutting machine time delay adjustment amount △ S is according to formula: △ S=△ L ÷ K ÷ V calculates; Wherein, △ S is cutting machine time delay adjustment amount, and △ L is each specification rear length adjustment amount, and K is base material rice anharmonic ratio coefficient, and V is this stream straightening speed.
Compared with prior art, the present invention has following beneficial effect:
The present invention is based on the full multiple length of Direct Rolling bar and produce online control system and the method for adjusting, by information acquisition device and cutter controller are connected on information process unit, the information exchange that information process unit gathers according to information acquisition device is crossed cutter controller control cutting machine and is carried out cutting action, the heap steel and the upper cold bed failure problems that in bar production, due to short chi, cause have been solved, guarantee production direct motion, improved to greatest extent scale rate and lumber recovery simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation:
Referring to Fig. 1, the present invention includes information process unit, and be connected with information process unit for gathering adjustment information and information feedack collector, on information process unit, be also connected with for controlling the motion of cutting machine and the cutter controller of cutting action; Information process unit is the computer that stores the Mathematical Modeling of each specification rear length adjustment amount △ L and flame cutting machine cutting time delay adjustment amount △ S.On cutter controller, be connected with for steel billet being cut into the cutting machine of specific length, cutting machine is for steel billet being cut into the flame cutting machine of specific length.The information exchange that information process unit gathers according to information acquisition device is crossed cutter controller control cutting machine and is carried out cutting action.
The invention also discloses a kind of control system and method for producing online adjustment based on the full multiple length of Direct Rolling bar, comprise the following steps:
1) first, every stream caster base is gathered to the information of the rear length adjustment amount △ L of this on duty produced scale rod bar by information acquisition device, and be delivered to information process unit;
2) then, the information that information process unit gathers information acquisition device is carried out computing, obtains cutting machine time delay adjustment amount △ S, and cutting machine time delay adjustment amount △ S is delivered to cutter controller; Cutting machine time delay adjustment amount △ S is according to formula: △ S=△ L ÷ K ÷ V calculates; Wherein, △ S is cutting machine time delay adjustment amount, and △ L is each specification rear length adjustment amount, and K is base material rice anharmonic ratio coefficient, and V is this stream straightening speed.
3) then, cutter controller sends instruction according to cutting machine time delay adjustment amount △ S to flame cutting machine, and every stream steel billet is positioned to cutting;
4) last, by information acquisition device, information or requirement after adjusting are fed back to information process unit, and storage.
Concrete, in bar Direct Rolling, while there are short chi steel on rolling rear cold bed, by adjusting work (or proof sheet work), every stream caster base is gathered to the information of the rear length adjustment amount △ L of this on duty produced scale rod bar by information acquisition device, and be delivered in the message handler of flame cutting console; Message handler is according to computing formula: each specification rear length adjustment amount of cutting machine time delay adjustment amount △ S=△ L ÷ base material rice anharmonic ratio COEFFICIENT K ÷ should flow straightening speed V, information is carried out to computing, and result of calculation is delivered to cutter controller; This result of calculation is sent instruction by cutter controller to flame cutting machine, and every stream steel billet is positioned to cutting; Finally by adjusting work (or proof sheet work), by information acquisition device, again information or new demand after adjusting are fed back to computer, and store.
