摘要： In a method and a roll stand for diagonal rolling of medium or thin-walled tube ingots, an inner mandrel rod is held at an inlet side and controllably axially displaceably relative to rolls. In order to avoid a funnel-shaped expansion at the tube ingot end, the rolling product during rolling is rolled in a constriction of the mandrel rod and thereby obtains a thickened wall forming a support of the tube ingot wall against the expansion.

摘要： Apparatus for laterally ejecting elongate articles, such as tube lengths, from a channel defined by a roller bed, the channel extending beyond a flying saw for severing continuous lengths into said elongate articles, said apparatus being operated by a signal generator fitted to the flying saw so that an ejection operation is initiated by an optional delay after completion of a severing operation. Operation is not impaired in the event of the tube being fractured during the rolling operation, since the ejection operation takes place in timed relation to the severing operation and does not depend on detection of the presence or absence of tube ends.

摘要： A process and apparatus for the production of seamless tubing incorporating a push bench is provided in which ingots are pierced in the longitudinal direction by diagonal rolls over the stopper rods of a piercing mill to provide pierced ingots having one end with a wall thickening which protrudes outwardly or inwardly, then the wall thickening ends reshaped to provide a partially closed end and finally the pierced ingots are forced through the roll passes of a push bench by mandrel rods engaging the partially closed end so that the ingots are formed into a tube bloom.

摘要： Ingots hot from rolling are pierced to form a hollow ingot by means of an internal tool of a press or skew-rolling line, and are subsequently elongated to form a tubular bloom by a stretching unit provided with a mandrel rod, and are finally finish-rolled. When inserting or withdrawing the internal tool into or out of the hollow ingot or the mandrel rod into or out of the tubular bloom, inert gas is introduced into the freed interior space in order to prevent scaling of the interior wall of the tubular bloom.

摘要： A method and apparatus for transverse, preferably skew, rolling seamless tube blanks, is provided wherein said seamless tube blanks are rolled down by a mandrel rod lying in their longitudinal bore or are rolled onto a mandrel rod at the delivery end. During transverse rolling each tube blank is subjected to a predetermined, controllable torque exerted by the mandrel rod in order to eliminate substantially the formation of pockets in the region of the sizing pass during transverse rolling.

摘要： This invention concerns a process and an arrangement for the production of seamless tube. An ingot heated to the rolling temperature is pierced in a skew-rolling stand to form a hollow ingot, is later stretched into a tube bloom and is rolled out into a finished tube. In order to improve this familiar process, it is proposed to conduct the stretching immediately after the piercing in the same heat as the latter, in which case the rolled goods is stretched in the same skew-rolling stand, but with a passage direction that is opposite to that of piercing. An arrangement with which this process according to the invention can be implemented is also proposed.

摘要： In a skew-rolling stand for rolling hollow billets, in particular for stretching hollow billets into tubular blooms, work material guides are provided at the entry end and/or at the delivery end. These work material guides comprise a preferably motor-driven guide tube (19) which can be rotated about its longitudinal axis, which considerably improves guiding and offers additional protection against heat losses and scaling of the work material. The guide tube does away with the need for a re-heating furnace and allows immediate subsequent finish-rolling.

摘要： The amount of materials in a piece of tubular stock is measured before the stock enters a stretch-reducing rolling mill and the mill is so controlled that the finished tube can be cut into lengths without the occurrence of overlengths or underlengths. In the case of a seamless tube, the piece of tubular stock is weighed and the flying means which cut the finished tube are so controlled that the lengths of all the finished pieces lie within prescribed tolerances so that there is no waste, other than the usual cropped ends. In the case of welded tube, the thickness of the strip material from which the tube is made can be welded, and the welded tubular stock can be cut to a suitable length to ensure that no overlengths or underlengths are obtained after the stretch-reducing and cutting of the finished tube into pieces of prescribed length, within tolerance limits.
