Abstract
A flat metal aligning device (21) which allows the flat metal entering a rolling stand (22) of a rolling mill to be effectively aligned or centered by using retractable pusher elements to control the alignment and feeding of metal work pieces into the rolling stand, thus avoiding potential damage to the working rollers (2) while reducing the times to produce the rolled products. Moreover, the device according to the invention allows the rolling stand to be supplied with short slabs when they may not be fed by the motorized rollers at the stand inlet, precisely due to their short length.
Claims12
A flat metal aligning device for aligning a flat metal entering a rolling stand, the device being adapted to cooperate with a longitudinal roller table underneath, which allows to feed the flat metal towards said rolling stand, said device comprising:
- side centering guides for centering the flat metal being fed on a longitudinal plane defined by said longitudinal roller table,
- pushing members for pushing the flat metal towards the rolling stand,
- first actuating means of said pushing members, each first actuating means actuating a respective pushing member, said first actuating means and respective pushing member being pivoted on a respective side centering guide,
- second actuating means, integrally fixed to each side centering guide, adapted to rotate said first actuating means and respective pushing member from a resting position over said longitudinal plane to a working position at said longitudinal plane, whereby the first actuating means actuate the respective pushing members to push and align the flat metal in proximity of the rolling stand.
A rolling plant comprising a flat metal aligning device for aligning the flat metals entering a rolling stand, the aligning device being arranged over a longitudinal roller table, which allows the flat metals to be fed towards said rolling stand, said aligning device comprising:
- side centering guides for centering the flat metal being fed on a longitudinal plane defined by said longitudinal roller table,
- pushing members for pushing the flat metal towards the rolling stand,
- first actuating means of said pushing members, each first actuating means actuating a respective pushing member, said first actuating means and respective pushing members being pivoted on a respective side centering guide,
- second actuating means, integrally fixed to each side centering guide, adapted to rotate said first actuating means and respective pushing member from a resting position over said longitudinal plane to a working position at said longitudinal plane, whereby the first actuating means actuate the respective pushing members to push and align the flat metal in proximity of the rolling stand.
A process of aligning flat metals entering a rolling stand, by means of an aligning device cooperating with a longitudinal roller table underneath, which allows to feed the flat metal towards said rolling stand,
- said aligning device comprising:
- side centering guides for centering the flat metal being fed on a longitudinal plane defined by said longitudinal roller table,
- pushing members for pushing the flat metal towards the rolling stand,
- first actuating means of said pushing members, each first actuating means actuating a respective pushing member, said first actuating means and respective pushing member being pivoted on a respective side centering guide,
- second actuating means, integrally fixed to each side centering guide, adapted to rotate said first actuating means and respective pushing member from a resting position over said longitudinal plane to a working position at said longitudinal plane, whereby the first actuating means actuate the respective pushing members to push and align the flat metal in proximity of the rolling stand;
- and the process comprising the following steps:
- centering a flat metal being fed on a longitudinal plane defined by the longitudinal roller table, by means of side centering guides;
- rotating the first actuating means and the respective pushing members, by means of the second actuating means, from a resting position over said longitudinal plane to a working position at said longitudinal plane;
- actuating the pushing members, by means of said first actuating means, to push and align the flat metal in proximity of the rolling stand.
