The present invention and the difference of conventional variable cross-section cold-reduced sheet milling method are:
1) band prolongs rolling direction and is broken down into several rolling units, and each rolling unit is expressed as dx and dy.Dx is
Relative to initial point position, dy is thickness of strip.Each rolling unit dx, dy value is determined by rolling aim curve.Unit passes through
The mode of tracking tracks the length of strip-rolling, is tracked based on band and determines dx, and depressing position is based on the corresponding rolling of dx
The thickness of strip dy of unit is executed.
2) position of calibrator can be adjusted in rolling direction based on the rolling cycle, it is ensured that thickness measure point and roll gap position
Set the consistency on the period.The several period depressing position coiling temperature setups in front, after rolling unit reaches calibrator, pressure
Position-force control, Roll-gap position are adjusted based on the deviation of band actual measurement thickness and setting thickness.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
