Application of the present invention, can eliminate short-tail phenomenon, to ensure to unload on cold bed the stability of steel, avoids occurring the phenomenons such as the improper or random steel of the off-position of tail steel on cold bed.
Detailed description of the invention
Below in conjunction with specific embodiment, technical solution of the present invention is elaborated.
Total length after every billet rolling is certain, wants to change the length of tail steel, can only realize (complementarity between the each segment length of nibbling shear) by the length (multiple lengths) that changes other multiple length sections.Optimize to shear and change latter end (tail steel) length by extending or shorten the length (multiple lengths) of multiple length steel just.For ensureing product sizing recovery rate, require to optimize the adjustment process of shearing and can not produce new non-scale, therefore length adjustment can only, taking product sizing length as unit, be adjusted by the integral multiple length of finished product cut lengths; Thereby can ensure an only non-scale of (at rear) appearance of every steel.
Step 1: set finished product cut lengths, multiple lengths;
This preferred embodiment adopts at the lower setup parameter of man-machine interface (HMI).
1, section length
HMI main menu → setting parameter → section length.
In this operation interface, can set finished product cut lengths, multiple length radical, additional length and shrinkage rate, show multiple lengths and manually optimize the setting situation of shearing.
2, multiple length adjustment
The adjustment of HMI main menu → setting parameter → section length → multiple length.
In this operation interface, can manually adjust the sheared length (multiple lengths, unit is product sizing length) of every section of steel.
Step 2: taking product sizing length as unit, change tail steel length by adjusting multiple lengths (sheared length).
1, length correction
HMI main menu → setting parameter → section length → length correction.
In this operation interface, can manually accurately revise the sheared length (unit is millimeter) of every section of steel, for revising due to the uneven error in length producing of steel billet temperature.
2, Optimal Setting
HMI main menu → setting parameter → section length → Optimal Setting
In this operation interface, show total length and average length after every billet rolling.Estimate overall length and the latter end automatic calculation optimization shearing result before and after adjusting of leaving a blank by setting.Wherein latter end is left a blank and is referred to the multiple lengths and the difference of optimizing the target length of shearing rear tail steel of integral multiple, and unit is product sizing length, and span is (0,3).
The result of calculation of pressing in this operation interface after computed push-buttom only plays demonstration effect, does not affect actual shearing effect.If satisfied to shown result of calculation, can press setting button, current result of calculation is applied in actual shearing.
3, optimize and revise
HMI main menu → setting parameter → section length → optimize and revise
In this operation interface, can set the target of optimizing and revising, the restriction of optimizing and revising and tail steel length.
Optimize and revise to shear after the afterbody of steel is by No. 0 hot metal detector and start working, No. 0 hot metal detector and the steel content between last rolling mill have determined the adjustment capability of optimization.So in actual applications, optimize and revise need taking Optimal Setting as basis, optimization of investment adjust before, need first complete or confirm Optimal Setting.
Optimize and revise target and comprise that tail end stretches out and the tail end free degree.Tail end stretches out the difference that refers to the target length of tail steel control and the multiple lengths (whole multiple lengths) of integral multiple, and unit is finished product length, and span is (1,0,1).Wherein 0 represents that optimizing and revising target is to make tail steel length equal the multiple lengths of integral multiple; 1 represents the large scale of multiple lengths of tail steel Length Ratio integral multiple;-1 represents the little scale of multiple lengths of tail steel Length Ratio integral multiple.The tail end free degree refers to the permission tolerance scope of tail steel length control, and unit is similarly finished product length, and span is (0～5).In the time that the tail steel length calculating is less than this setting value (the tail end free degree) with the difference of optimizing and revising target length, program will not carried out length adjustment.Carry out the scope of Automatic Optimal adjustment, pass through after No. 0 hot metal detector at the afterbody of steel, system calculates the total length of steel automatically, thereby can obtain the calculated value of tail steel length, only have in the time that Automatic Optimal is adjusted the target length of tail steel and the difference of tail steel length computation value and is greater than the tail end free degree, be just optimized adjustment.
The restriction of optimizing and revising comprises upper and lower bound: the upper limit refers to optimize and revise the length that allows increase in process on the multiple lengths of integral multiple, and unit is finished product length, and span is (0,1); Lower limit refers to optimize and revise the length that allows minimizing in process on the multiple lengths of integral multiple, and unit is finished product length, and span is (1～-5).
Tail envelope length refers to the restriction of last sheared length, and in the time that tail steel length is less than tail envelope length, Double Dimension Flying Shears is not sheared for the last time.
The optimization of pressing this operation interface is sheared button and can be dropped into/cancel and optimize and revise function.In addition, can also optimize and revise function by drop into/cancellation of method below:
HMI main menu → function is selected → optimizes to shear.
4, optimize monitoring
HMI main menu → diagnostic function → optimization monitoring
This operation interface is for monitoring the result of calculation of optimizing and revising.Before optimization of investment is adjusted function, should first carry out manual Optimal Setting and set the target of optimizing and revising, the restriction of optimizing and revising, then in this operation interface, monitor the result that Automatic Optimal is adjusted, after the result of optimizing and revising is correctly stable, can adjust function by optimization of investment.
