摘要:
The invention relates to a casting wheel of a strip casting machine. The casting wheel comprises a casting ring (30) mounted and borne internally on freely rotatable rollers (31a, b, 33a, b). In the zone of the position at the start of casting, the rollers (31a, b) are rigidly mounted via a supporting element (32), while on the opposite side they are radially adjustable via a-supporting element (34a, b). In this way deformations of the casting ring (30) due to heating during casting can be absorbed without a change in the position of the casting ring (30) as at the start of casting. The casting ring (30) is driven from outside via at least one driving element (30b) which is connected via a transmission member (30a) to the casting ring (30).

An apparatus for coiling webs of material, more particularly webs of material (5) arriving from a ribbon casting machine, and for coiling the webs of material (5) if necessary. For the purposes of guiding and coiling, brush rollers (20, 21, 23-26) are used consisting of axially spaced-out annular disc-shaped brush elements between which guide elements (27) extending in the direction in which the ribbon runs are disposed, which prevent the web of material (5) of low rigidity from becoming wound around a brush roller (20, 21, 23-26).

摘要:
Web unwound from a supply roll is slit into a plurality of bands by a slitting unit comprising circular disc blades. The individual bands are subjected to tension by a brake roll assembly positioned before the take up roll to hold the individual bands taut with a predetermined braking force in such manner that different degrees of slippage relative to the brake roll and the individual bands are effected.

A process of treating metal strips using a linear electric motor with spaced apart motor elements comprises directing the metal strips into the space between the motor elements and operating the motor to produce a travelling wave and advancing the strip between the motor parts without contact thereof at a velocity greatly reduced with respect to the velocity of the linear electric motor wave so as to produce a slippage between the wave and the strip and to effect the heating of the strip as it is advanced. The apparatus includes a linear electric motor including a first motor unit spaced away from a second motor unit in the form of a linear motor or return bar so as to form a gap therebetween through which the metal strip is advanced. The apparatus includes means for feeding the strip through straightening rolls and cropping shears, S-rollers and coiling and uncoiling reels.

The invention relates to a process for levelling continuously moving metal strips exclusively by tensile rolling levelling. The strip to be levelled is subjected to two successive tensile rolling operations in the direction in which it moves. In the first tensile rolling operation the tensile rolling levelling is performed with relatively low tensile stressing and considerable rolling deformation, while over the second tensile rolling distance the strip is subjected to only slight bending with substantially higher tensile stressing. The result of these successive different kinds of stretching-and-rolling levelling is a flat strip which maintains its flatness even after a prolonged storage period.
摘要:
The cast metal strip is retained on both sides between supporting and conveying elements, the supporting and conveying elements comprising on one side a group of wire cables 6, 12, 18, 27 and on the other side either a similar group of wire cables 5, 24 or a cooling roller 11, 17 or a coiler 23. The wire cables 5, 6, 17, 18, 24 and 27 ensure that the cast metal strip 4 is guided with as small a contact area as possible, so that on the one hand the strip is less stressed and on the other hand can irradiate heat.
摘要:
To obtain flat component strips from a cold-rolled metal strip inexpensively and with the minimum use of technical apparatus, slitting shears 5 are disposed between sets of tensioning drums 3, 4; 11, 12, more particularly between the inlet side set of tensioning drums 3, 4 and a straightening unit 6 of a stretch flattening apparatus for a metal strip 1. This arrangement of the slitting shears eliminates the additional stretch flattening of the component strips otherwise required after the metal strip itself has already been stretch flattened. The component strips between the two sets of tensioning drums 3, 4; 11, 12 also acquire the same length.
摘要:
The present invention relates to a process and to a device for the rolling of bands (B) with uneven thickness and/or length distribution over their width by using at least one control roller (5, 9, 21, 27, 41, 43) located on the inlet and/or outlet side of a mill (W, W', W") and capable of swiveling in its position relative to the band (B), making it possible in case of minor disturbances, independently of the existing operating conditions, to compensate for the running of a band caused by unevenness in the thickness and/or length distribution over the width of the band. This is achieved according to the invention in that the distribution of the tensile stress over the width of the band (B) is detected with at least one measuring device (7, 11, 25) and in that the control roller (5, 9, 21, 27, 41, 43) is adjusted in function of the detected distribution of tensile stress until the detected distribution of tensile stress is equal to a desired value.
