The control of a tandem rolling mill is multi-layered. Two examples are shown for BlueScope Steel's No.2 temper mill with the exit stand configured for strip shape (flatness). At the lowest level is the current/voltage control of the DC electrical drive motors. WebbThe rolling process in the cold rolling mill. In order to reduce the steel strip down to thicknesses of only 0.25 to 0.3 mm, the strip is first freed from any adhering scale in the continuous pickling line. Rolled into coils again, the steel is heated in the bell annealer. During the actual rolling process, the steel is given its final material ...

WebbTsubaki’s lineup of jacks consists of three types: trapezoidal screw, ball screw, and high-lead ball screw. Trapezoidal screws include a stainless steel type and a left-hand screw … WebbThe ratio of the rolling force to the amount of vertical deformation of the whole rolling mill, including the deformation of the roll, screw-down device, and housing, is called the mill modulus. The mill modulus is 500-1,000 ton/mm for plate rolling mills and 400-600 ton/mm for cold rolling mills. The larger the diameter of the back-up rolls ... edward beard budding
