    摘要: Process for deforming a piece of thin-walled metal tube, comprising the operations of bending the piece of tube with respect to its original axis, in which process the wall of the piece of tube is firstly provided, at least at the location where the bend is intended to be, with a deformation which extends substantially in the longitudinal direction of the piece of tube, and in which process wall material is moved closer to the neutral plane of bending, and the piece of tube is then bent, after which the ultimate shape of the piece of tube which is to be deformed is imposed by hydroforming.

    摘要: A method for coating a moving steel strip with a metal or metal alloy coating, wherein the steel strip runs through a bath of molten metal or metal alloy to coat the steel strip, and the coated steel strip is wiped to control the thickness of the coating using foils or sheets. The bath of molten metal has a volume at most 10,000 times the volume V of the coating on the steel strip per second, volume V in m3 being given by the formula V=2×d×w×s, wherein d=the thickness of the coating in meters, w=the width of the strip in meters, and s=the velocity of the strip in meters per second.
