摘要： A rolling mill comprising a movable mill stand mounted in slideways and enclosing grooved mill rolls whose necks are coupled with a hydraulic drive and with gear wheels in mesh with each other. A drive for reciprocating said movable mill stand is equipped with at least two linear inductors installed immovably and at least two electrically conductive bars connected rigidly to movable mill stand separators and braces. The bars are adapted to move intermediate of said inductors and have a length exceeding that of said inductors and begin of a value of at the maximum transfer of said movable mill stand. By establishing inductive currents and, hence, electromagnetic forces in the bars, the inductors develop through said bars pulling or pushing forces acting on said movable mill sand sufficient to provide a requisite roll force. The mill roll hydraulic drive is an auxiliary one.

摘要： Method and apparatus for reducing the thickness of metal in which a pair of freely rotatable work rolls disposed on opposite sides of the metal are oscillated in synchronism upon a pair of oscillatable arms to subject the metal to rolling action of the arms, and in which auxiliary load-applying means are included to influence the roll displacement force at particular positions of arm oscillation so as to urge the work rolls towards straight line parallel movement.

摘要： A device for drawing a metal rod, particularly, a cast steel rod comprises one or more deforming rollers which are arranged to engage the rod on opposite sides thereof as it is moved thereby. The rollers are moved by a mechanism to provide for the desired drawing down from a wide diameter down to a relatively small diameter. The mechanism includes a pivotal support member which carries a deforming roll and which is moved by a first rotating crank into pressure force engagement with the rod being cast as the rod is moved thereby. The mechanism also includes an additional second crank mechanism for engagement with the support for shifting the support in a substantially longitudinal direction in respect to the rod being formed. In a first embodiment the second crank for controlling the longitudinal direction of movement of the support engages the support by means of a pushrod having a pin which is guided in a slot defined in the direction of the longitudinal axis of the support member and which is also guided by a sliding block. In another embodiment the engagement of the second crank with the support is a direct engagement. The drive for the crank includes a gear which drives through an idler gear to the crank for moving the support member in a direction toward and away from the rod being cast. An alternate embodiment includes a direct gear drive from the first crank to a gear carrying the shaft for the second crank.

摘要： A ring manufacturing method and a ring manufacturing apparatus according to the invention does not require the preparation of a specially shaped plate material for each type of ring plate to be manufactured. It is therefore possible to manufacture a ring plate of any thickness or width with a high degree of accuracy even in high-variety, low-volume production. In a plate material forming step, a round bar 1 is formed by rollers 3, 4 into a plate material having any desired cross-sectional shape. In a slant rolling step, the plate material is slant rolled by slant rollers 9, 10 and thereby formed into a specially shaped plate material whose thickness increases in the width direction from one side to the other. In a ring forming step, this specially shaped plate material is formed into a ring shape by a ring forming device 14. The specially shaped plate material can be formed on the ring forming production line, whereby the accuracy of the shape of the resulting ring is achieved without having to separately prepare a specially shaped plate material for each type of ring plate to be manufactured.

摘要： A method of continuously casting a molten metal in a casting means to obtain a solidified cast bar at a hot-forming temperature, passing the cast metal at a hot-forming temperature from the casting means to a hot-forming means, and hot forming the cast bar into a wrought product by a two-stage reduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a shell of finely distributed recrystallized grains in the surface layers of the cast bar by compressive forging affecting at least the surface layer of the cross section of the bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area by rolling deformation forms the desired wrought product. The shell of fine grains formed on the cast bar during the first stage of compressive deformation permits substantial reduction of the cross-sectional area of the cast bar during the second stage of rolling deformation without the cast bar cracking, even when the cast bar has a high impurity content or is otherwise susceptible to intergranular rupturing.
