Methods of rolling wire rods or bars |
摘要 |
In the reduction of the cross section of wire, rods or bars by rolling, the work material is placed under longitudinal compression in a roughing block and/or in an intermediate block and is only under tension in a finishing block. By this means, the ends of the work material are thinned prior to entry into the finishing block, instead of being thickened as they would be if the work material were under tension in the roughing and/or finishing block. Compensation for this end thinning is effected in the finishing block due to the rolling under tension, so that wastage due to cropped thickened ends is avoided.
