A section straightening machine is operated by a method which involves passing the structural sections through the array of straightening tools. Section straightening forces are applied to adjustable shafts carrying the tools and adjusters at the service sides of the shaft applying forces acting counter to the section straightening forces.

Method of operating a section straightening machine

In a straightening machine for straightening sections like rolled beams, wherein tools () are arranged on a plurality of mutually parallel driven straightening shafts () disposed above and below the alignment line in the transport direction of the product to be straightened, and of which preferably the upper straightening shafts () are adjustable for setting the straightening gap, the straightening shafts () are individually adjustable and each have on both sides an adjusting means engaging straightening shaft ends () whereby in straightening operations at least the adjusting means on the service side () remote from the drive side I is provided with a force (F) acting opposite to the straightening force (F) relevant hereto.

Section straightening machine

A rolling train for the continuous rolling of strand shaped products has at each rolling location a pair of fixed stations which are closely spaced and have rails such that a mill stand at one station can be displaced away from the rolling line and be replaced at that location by a mill stand at the other station. The mill stands can be connected to the respective control and operating media sources by lines which are unreeled as the mill stand is moved away from the operating position or reeled up as the mill stand is moved into an operating position.

Rolling line for the continuous rolling of strand-shaped products

Rolling stock is transported in a transporting device from a front roll stand to a rear roll stand. Between the roll stands, the rolling stock carries out an oscillation transverse to the transporting direction. At least one characteristic property, amplitude or frequency, of the oscillation is determined quantitatively and, from this determination, a tension or compression, existing in the rolling stock between the roll stands is determined. One of the roll stands is readjusted in such a manner, that a desired tension is built up in the rolling stock between the roll stands.

Method for controlling the tension between roll stands of mill trains for steel bars, wire or profiles

A method of rolling finished sections from preliminary sections by means of roll stand arrangements which operate in reversing operation and include a compact rolling group composed of a first universal stand at the entry side and a second universal stand at the exit side and an intermediate edging stand arranged between the universal stands, and a roughing group arranged in front of the compact rolling group and composed of vertical roll stands and horizontal roll stands and/or universal stands. A rectangular preliminary section or a preliminary section having the approximate final dimensions is preshaped in the roll stands of the roughing rolling group in a number of shape changing passes and/or shape reduction passes, possibly reversing with or without the use of selectable grooves. Subsequently, the section is further shaped in the compact rolling group in several shape changing passes or shape reduction passes in the universal stand on the entry side. Subsequently, the section is shaped into the finished section in the universal stand on the exit side or in the intermediate edging stand, possibly also with the use of the selectable grooves or the grooves of the roll stands located next to each other.

A rolling train for rolling flat steel using universal stands having--instead of vertical rolls--adjustable support members for pairs of loose vertical rollers arranged in the areas of the stands. The rolling train includes a roughing rolling group with vertical two-high stand or universal stand and horizontal two-high stand and a compact rolling group composed of two tandem universal stands and arranged following the roughing rolling group, wherein the two universal stands of the compact rolling group are equipped with non-driven adjustable vertical rollers.

A method of operating a roll stand arrangement including one or more edging/roughing stands followed by a compact rolling group arranged transversely offset relative to the edging/roughing stands and connected to the edging/roughing stands through connecting roller conveyors and a transverse conveying unit. The compact rolling group is composed of first and second universal stands or two-high stands and an intermediate edging stand arranged between the first and second stands. In accordance with a predetermined cycle, preliminary sections arriving from a continuous casting plant are supplied directly without intermediate storage to the roll stand arrangement and are finish rolled successively in the compact rolling group into profiled rolled strands and are supplied, before or while the next following preliminary section enters the compact rolling group, to a cooling bed arranged laterally of the rolling line. When rolling sections whose finish rolling time is longer than the cycle predetermined by the continuous casting plant, a first length portion of the rolled strand which has already emerged from the compact rolling group is severed from the rolled strand and is supplied to the cooling bed.

Method of operating a roll stand arrangement

A method of casting and rolling and a roll stand arrangement for rolling finished sections (sheet piling sections) from a preliminary section which arrives from a continuous casting machine and has approximate final dimensions. The method utilizes roll stand arrangements which operate in a rolling line in a reversing operation. A roughing rolling group has in a first rolling line a runout roller table and a transverse transport device following the runout roller table and in a second rolling line a parallel run-in roller table for a compact tandem stand group. A horizontal stand of the roughing rolling group and/or an intermediate edging stand of the compact tandem stand group each have two selectable grooves, wherein a universal stand on the exit side of the compact tandem group has one or more two-high horizontal stands with grooved rolls. When rolling with this stand arrangement, for adjusting the width and for adjusting the shape of a preliminary section having a H-shaped cross-section while simultaneously reducing the cross-section in the roughing rolling group, further reduction of the cross-section with deformation of section ends for forming interlocks is carried in the compact tandem stand group and a final finish-shaping of the interlocks of the section is carried out in the grooves of the two-high horizontal stands.

Method of casting and rolling and roll stand arrangement for rolling

A rolling plant for rolling all types of finished sections from flat blooms or preliminary sections with close to final dimensions, wherein the blooms or preliminary sections arrive from a continuous casting plant and may be stored in reheating furnaces arranged in front of the plant and/or may be maintained at rolling temperature. The rolling plant includes a compact rolling group with two universal stands arranged closely one behind the other and an edging stand arranged between the universal stands. A roughing group is arranged in front of and parallel offset to the compact rolling group, wherein the roughing group is composed of a group of a vertical stand, a horizontal stand and a universal stand arranged closely one behind the other. A roller table each is arranged in front of and following the compact rolling group, wherein the length of each roller table corresponds to the exit length of the finish-rolled stock; arranged following the roughing group is another roller table which extends parallel to the two roller tables over the length of both of these roller tables and past the compact rolling group, wherein transverse conveying units are arranged between the parallel roller tables.

Rolling plant for rolling all types of finished sections

A method of rolling finished sections from a preliminary section by initially carrying out five or more passes and reversing passes between a universal stand and a horizontal stand, wherein profiled horizontal rolls of the universal stand form in the section two indentations located opposite of each other and offset relative to a longitudinal center of the section. Subsequently, head and flange projections of an emerging rail section are preshaped and the indentations are laterally reduced by one of alternative grooves of a horizontal stand of a preliminary rolling group. The emerging rail section is rolled in a reversing operation after three or more passes in the universal stand and in two alternative grooves of an intermediate upsetting stand. The section is finish-rolled into a rail section in an additional pass through the universal stand.

Method of rolling finished sections from a preliminary section

A method of operating a roll stand arrangement composed of one or more roughing stands and a compact rolling group arranged downstream of the roughing stands and transversely offset relative to the roughing stands. The compact rolling group is connected to the roughing stands through roller conveyors and a transverse conveying unit. The compact rolling group is composed of a first and a second universal stand or two-high stand and an intermediate upsetting stand between the first and second stands. Preliminary sections arriving from a continuous casting plant are supplied directly or after intermediate storage to the roll stand arrangement. The rolling stock strand which has been rolled in the roughing stands is supplied optionally from a first entry side or a second entry side into the compact rolling group in dependence on the number of passes required by the respective rolling program.
