摘要： A wire-rod and the like, hot-rolling machine wherein the two rollers are fitted on respective frustoconical end portions of as many counter-rotating supporting shafts, via interposition of corresponding centering and coupling bushings having a frustoconical internal profile, each of which is fitted on the end portion of a respective supporting shaft, between the supporting shaft and the corresponding roller, and is structured so as to mesh on the supporting shaft so as to be angularly integral to said supporting shaft, and so as to be inserted/wedged between the supporting shaft and the roller thus to center the roller on the supporting shaft and moreover make the roller angularly integral to the body of the supporting shaft. Each centering and coupling bushing is provided with an annular flange having an eccentric lobe-shaped profile and which cantilevered projects from the outer surface of the bushing, at one of the two mouths of the central through hole of the roller, and is designed to engage a corresponding annular groove with eccentric lobe-shaped profile which is formed on the body of the roller at the mouth of the roller central through hole, and has a shape complementary to that of the annular flange.

摘要： A mandrel mill a method for manufacturing a seamless pipe by using the mandrel mill includes a plurality of roll stands in which three grooved rolls R are disposed in each roll stand such that an angle formed by pressing directions is 120° and the pressing directions of the grooved rolls R are alternately shifted by 60° between adjacent roll stands, wherein a central angle θ defining a circular arc that constitutes a groove bottom profile of the grooved roll R disposed at least in the first and second roll stands is set at less than 60°. The mandrel mill can adequately suppress the problem of the mandrel bar not being able to be pulled out from a pipe after drawing and rolling, without resulting in an increase in facility cost and deterioration of maintainability.

摘要： A pipe in which polygonization is substantially eliminated is manufactured by a reducer with a grooved roll with a groove having a groove bottom zone including the center of the groove in the roll axial direction and flange zones adjoining both sides of the groove bottom zone. The groove surface has a friction distribution in the roll axial direction such that the frictional force with respect to a material being rolled in the groove bottom zone is larger than the frictional force with respect to a material being rolled in the flange zones. This friction distribution can be achieved by working the groove surface so that the surface roughness of the groove bottom zone becomes greater than the surface roughness of the flange zones or by applying a lubricity modifier which differs with respect to amount and/or type between the groove bottom zone and the flange zones.
摘要翻译：其中多边形基本上被消除的管道由具有沟槽辊的减速器制成，槽的槽具有包括在辊轴向方向上的槽的中心的槽底区域和与槽底区域的两侧相邻的凸缘区域。槽表面在辊轴向方向上具有摩擦分布，使得相对于在槽底区域中被轧制的材料的摩擦力大于相对于在凸缘区域中被轧制的材料的摩擦力。这种摩擦分布可以通过加工凹槽表面来实现，使得凹槽底部区域的表面粗糙度变得大于凸缘区域的表面粗糙度，或者通过施加相对于凹槽之间的量和/或类型不同的润滑性改进剂底部区域和法兰区域。

摘要： The invention relates to a method for producing seamless tubes from metal, particularly from steel, wherein a previously produced hot hollow block is stretched by means of a three-roll bar rolling mill on a mandrel to form a parent tube and, before running into the bar rolling mill, the hollow block is provided with a rolling step that makes the diameter more uniform by means of an upstream stand. It is in this case provided that the rolls of the upstream stand are moved apart and together to the same extent as the deforming stands of the bar rolling mill, wherein the calibrating base radius of the rolls of the upstream stand extends over 60° and this is followed by a flank radius with a tangential transition which is dimensioned such that even with the maximum setting of the rolls in the region of the flank there is virtually no diameter reduction of the largest hollow block diameter to be expected.

摘要： A multi-roll mandrel mill comprises a plurality of grooved roll bodies as a roll pass for elongation rolling of a shell and a plurality of roll stands, each having roll shafts and roll chock portions for driving the grooved roll bodies for driving the grooved roll bodies, wherein bearings are internally contained in each grooved roll body. Optimizing the design of roll chock portions for every setup is achieved by a tube-making setup of the mandrel mill, wherein at least one of either or both of the roll shafts and the roll chock portions is replaced with a part(s) having a different shape(s) in addition to changing of the grooved roll bodies. The optimization of the design is effective in preventing underfill and overfill.
