Abstract
The invention relates to the field of automatic control of a cleaning section of a vertical electrolytic tank of a continuous annealing production line, in particular to a variable tension control method of the cleaning section of the continuous annealing production line, which is characterized in that the thickness of a steel plate is detected before a cleaning section is accelerated and sleeved, and a corresponding tension value is calculated according to the thickness of the steel plate and the operation speed of the cleaning section so as to reduce the fluttering of strip steel, and the specific principle is as follows: when the thickness of the strip steel is less than or equal to 0.5mm, the tension is calculated by adopting the following formula: t = kqwh, wherein
Compared with the prior art, the invention has the beneficial effects that: after the scheme is implemented, the generation of scratches during high-speed sleeve filling of thin materials in the vertical electrolytic cell cleaning section of the continuous annealing production line is basically eliminated, so that the quality of strip steel is obviously improved, and the rejection rate and the defective rate caused by scratches are zero.
Description
Technical field
The present invention relates to continuous annealing production line vertical electrolyzer cleaning section automation field, relate in particular to a kind of company and move back cleaning section variable-tension control method.
Background technology
At present, when continuous annealing production line cleaning section production thickness is less than the thin material steel plate of 0.5mm, set tension force conventionally less, generally between 4.8KN～13.6KN, this set(ting)value can meet the demands when cleaning section speed stabilizing is produced, but filling in cover process at a high speed, the band steel of cleaning section waves larger, and the phenomenon of grazing battery lead plate and nozzle happens occasionally, surface of steel plate is produced and wipe scuffing, this wiping scratches and in postorder is produced, is difficult to process, and therefore directly affects product surface quality, causes waste product and substandard products.
Summary of the invention
The object of this invention is to provide a kind of company and move back cleaning section variable-tension control method, move back unit and rationally improve cleaning section tension force in filling at a high speed cover process connecting, bring up to 9.6KN～22.8KN, reduce band steel and wave, and then reduce because of surface of steel plate and wipe and scratch waste product, the fraction defective producing.
To achieve these goals, technical scheme of the present invention is such:
Cleaning section variable-tension control method moves back in a kind of company, before cleaning section raising speed is filled cover, the thickness of steel plate is detected, according to the thickness of steel plate and cleaning section travelling speed, calculate corresponding tension value, to reduce band steel, wave, its Specific Principles is: when belt steel thickness is less than or equal to 0.5mm, tension force adopts formula below to calculate:
T=kqwh, wherein
In formula: T cleaning section tension value, unit is newton,
Q cleaning section unit tension value, gets 16 newton/square millimeters,
W cleaning section strip width, unit is millimeter,
H cleaning section belt steel thickness, unit is millimeter,
V cleaning section strip speed, unit is meter per second,
K cleaning section tension force magnification factor.
In formula, min (a, b) gets minimum value in value a and b; Max (a, b) gets maximum value in value a and b.
Compared with prior art, the invention has the beneficial effects as follows: after scheme implementation, basically eliminate continuous annealing production line vertical electrolyzer cleaning section at thin material, fill at a high speed when cover and wipe the generation scratching, make obviously to improve with the quality of steel, because wiping, to scratch the scrap rate, the fraction defective that cause be zero.
Accompanying drawing explanation
Fig. 1 is that the present invention fills cleaning section speed and curvedization of tension force graphic representation while overlapping.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
The inventive method is exactly when thin material fills at a high speed cover, according to the speed with steel, tension force correspondence is adjusted, to reduce band steel, waved, and then reduce because of surface of steel plate and wipe and scratch waste product, the fraction defective producing, when belt steel thickness is less than or equal to 0.5mm, cleaning section tension force adopts formula below to calculate:
In formula: T cleaning section tension value, unit is newton,
W cleaning section strip width, unit is millimeter,
H cleaning section belt steel thickness, unit is millimeter,
V cleaning section strip speed, unit is meter per second.In formula, min (a, b) gets minimum value in value a and b; Max (a, b) gets maximum value in value a and b.
Seeing Fig. 1, is embodiment of the present invention cleaning section speed and curvedization of tension force graphic representation when filling cover, implements to become after tension control, and it is obviously less that the wiping with steel when filling cover at a high speed scratches phenomenon, and its corresponding described point coordinate figure is as following table 1.
