Description
Technical field
The utility model relates to the high Two-stand Temper Mill of a kind of elongation control precision.
Background technology
Cold rolling levelling is rolled with less plastic deformation the band steel after recrystallization annealing, to eliminate yield point elongation, control panel shape, and obtain the operation of rolling of the surface topography required, it no matter is traditional or the cold-rolling process process in modern times, the smooth production link that is all absolutely necessary, due to smooth be determine the belt plate shape of finished product, last procedure of mechanical performance, so the percentage elongation of planisher and Strip Shape Control, the quality improving cold-strip steel is had very important significance
But in elongation control process for enter planisher place strip speed detect and go out planisher place strip speed detect all have great importance, the strip speed that the tachymeter at two places records will directly affect the method for elongation control, existing tachymeter is generally single camera and tests the speed, or adopt dual camera to test the speed, certainty of measurement is poor.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides the Two-stand Temper Mill that a kind of elongation control precision is high, by improving the accuracy measuring strip speed, improves the precision of elongation control.
The technical scheme that the utility model adopts is such: the Two-stand Temper Mill that elongation control precision is high, comprise the first frame and the second frame, described first frame is provided with the first top backing up roll, first lower support roll, intermediate calender rolls on first, first time intermediate calender rolls, first top working roll, first bottom working roll, described second frame is provided with the second top backing up roll, second lower support roll, intermediate calender rolls on second, second time intermediate calender rolls, second top working roll, second bottom working roll, the porch of described first frame and the exit of described second frame are provided with the tachymeter for detecting steel band speed, described tachymeter comprises bracing frame triangular in shape, each drift angle place of support frame as described above is provided with the camera that tests the speed, the camera that tests the speed described in each is all connected with the controller of tachymeter.
Further improvement: the surface of described first top working roll and the first bottom working roll has by the superficial layer of electric spark hair flower process, the surface of described second top working roll and described second bottom working roll has by the superficial layer of grinding process, and the roughness of the superficial layer of described first top working roll and the first bottom working roll is greater than the roughness of described second top working roll and described second bottom working roll face side.
Further improvement: the surface roughness of described first top working roll and the surface roughness difference of described first bottom working roll are less than 0.1 μm, the surface roughness of described second top working roll and the surface roughness difference of described second bottom working roll are less than 0.1 μm.
By adopting preceding solution, the beneficial effects of the utility model are: test the speed to band steel by adopting three of distribution triangular in shape cameras simultaneously, the velocity amplitude that three cameras record is averaged by controller, thus improve the accuracy tested the speed, be beneficial to the raising of elongation control.
