Rolling mill for manufacturing tube and rod, includes rollers in roller frame located in stand, with adjusters which can be swung or translated and locked in position

摘要

The rollers (3, 4, 5) are arranged in a roller frame (9) located in a rolling stand. Roller adjusters (6, 7, 8) are included. The adjusters can be swung about or moved in translation along, an axis parallel to the product length; they can also be locked in position. The roller frame is free of roller adjusters. It includes bearings and/or guides for the rollers. The adjusters (6, 7, 8) can be used to move the roller frame relative to the rolling stand. The adjusters include actuators. The adjuster actuators are hydraulic or mechanical components. Roller frame adjusters are alternatively constructed as stops, which are fixed in the roll stand. The adjusters have centering. As the adjusters approach the roller frame, a defined relative position is adopted by the centering. The centering acts in two stages. The adjusters, moving by swinging or translating, release or open an insertion opening for the roller frame. An exchange carriage for the roller frame is positioned near the rolling mill.
