摘要： A rolling mill plant has a planetary skew rolling mill and a reducing or sizing rolling line disposed at a short distance therebeyond for the purpose of manufacturing tubes. In order to avoid axial stressing of the work material between the planetary skew rolling mill and the reducing or sizing rolling line when the work material is simultaneously located in both of them, a tension and compression measuring device is disposed in the region of the reducing or sizing rolling line for the purpose of corresponding regulation of the latter's drive motor. A torque measuring device is disposed between the mounting of the mandrel rod of the planetary skew rolling mill in order to be able to detect torque stresses in the work material which are then eliminated in dependence upon the measured values of the torque measuring device by corresponding regulation of the rotational speed of the rolls and of the rotor of the planetary skew rolling mill.

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： In a transmission for driving the rolls of a rolling line having a number of rolling stands disposed one after another, a respective planetary transmission stage is provided at several output shaft (20) and forms the output rotational speed from a basic rotational speed and an additional rotational speed. The gear wheels (2,23) of the gear wheel transmission trains transmitting the basic and additional rotational speeds are mounted on stationary bearing bushes (3, 26) which project into the hub regions of the gear wheels (2, 23) and are secured in bores or on flange facings of the load-bearing walls (5, 6) of the transmission housing (1). Only one of the gear wheel transmision trains is disposed between the load-bearing walls of the transmision housing, while the other is disposed on the outside stands. This permits the transmission to be of lighter construction and allows greater gear ratios in the gear wheel transmission trains and a smaller distance between the output shafts (20).

摘要： In a rolling mill plant for the manufacture of seamless tubes, a piercing mill (2), a planetary skew rolling mill (15) and a sizing or stretch-reducing rolling mill (18) are arranged one after the other. In order to improve the output and the quality of the products of plant of this kind, it is proposed not to withdraw the shaft rods (11) used during the piercing operation in the mill (2), but also to use them as internal tools in the planetary skew rolling mill (15). The shaft rods can then remain at the entry end upstream of the planetary skew rolling mill (15) from where they can be returned to the piercing mill (2). Alternatively (FIGS. 2 and 4) they can also pass through the planetary skew rolling mill and be returned from the delivery end thereof to the piercing mill. The insertion, hitherto required, of rods into the hollow ingots before entering the planetary skew rolling mill is not required. The heavy scaling of the surface of the bore in the hollow ingot thereby occurring is avoided.

摘要： The invention concerns a gear unit for driving the rolls of a roll train with a number of consecutively arranged roll stands. This gear unit has planetary gear sets at at least one output shaft, which are located one behind the other at short distances. Due to a crosshead provided in accordance with the invention, the output shaft of each planetary gear set is relieved of bearing forces and the torques of the gears, such that it can have a small diameter, which in turn permits a building up of the planetary gear set, such that the operating torque and the operating r.p.m.'s of the planetary gear sets can be considerably higher than in the familiar construction types.
