Abstract
An apparatus and method for safely and efficiently polishing the work rolls of a metal sheet or plate leveler. The apparatus includes a support and one or more polisher assemblies to be inserted between the upper and lower work rolls of the leveler, for simultaneously polishing the upper and/or lower work rolls of the leveler during the rotation of the work rolls.
Claims38
An apparatus for polishing the work rolls of a metal, each said work roll having a work roll circumference and a work roll length, the leveler having a frame, a series of upper work rolls and a series of lower work rolls, said apparatus comprising:
- one or more polishing units sized, shaped and configured to be removably inserted between the series of upper work rolls and the series of lower work rolls of the leveler, said polishing unit comprising at least one polisher configured for engaging and polishing at least one of said series of upper and lower work rolls of the leveler during the rotation of said work roll,
- said at least one polisher including a substantially rigid concave pan having an abrasive material positioned therewithin for exposure of said abrasive material to said respective work roll upon engagement of said polisher with said respective work roll and upon rotation of said work roll within said substantially rigid concave pan.
A method for polishing the work rolls of a metal leveler through the use of a polishing apparatus, comprising the steps of:
- configuring the leveler into a polishing position to accept the insertion of the polishing apparatus;
- configuring the polishing apparatus into an orientation position to enable insertion of the apparatus into the leveler,
- inserting the polishing apparatus into the leveler, wherein the polishing apparatus includes polishers configured from substantially rigid concave pans which can be simultaneously aligned for engagement with respective work rolls to polish respective ones upper and lower work rolls of the leveler during the rotation of the work rolls, wherein at least one of the polishers is configured to engage and polish substantially the operable length of a corresponding work roll of the leveler;
- extending the upper and lower polishers to engage the upper and lower work rolls of the leveler during rotation of the work rolls;
- and
- simultaneously polishing the contacted work rolls, during the rotation of the work rolls.
A method for polishing the work rolls of a metal leveler through the use of a polishing apparatus, comprising the steps of:
- configuring the leveler in an open position;
- inserting said polishing apparatus into the leveler, wherein the polishing apparatus includes polishers on its top and bottom surfaces for simultaneously engaging and polishing the respective work rolls of the leveler during the rotation of the work rolls, wherein at least one of the polishers includes a substantially rigid concave pan having an abrasive material therewithin, said pan being configured to engage and polish at least a majority of a length of a corresponding work roll of the leveler;
- juxtaposing the polishers and the upper and lower work rolls of the leveler by extending the polishers to further contact the work rolls, during the rotation of the work rolls,
- rotating the work rolls to polish same within the polisher pans.
A method for polishing the work rolls of a metal leveler through the use of a polishing apparatus, comprising the steps of:
- configuring the leveler into an open position to accept the insertion of the polishing apparatus,
- inserting the polishing apparatus into the leveler, wherein the polishing apparatus includes upper and lower polishers restrainably positioned relative to one another along both sides of a platform, said polishers being configured from substantially rigid concave pans which can be simultaneously aligned for engagement with respective work rolls containing an abrasive material,
- lowering the upper work rolls to engage the upper polishers;
- continuing to lower the upper work rolls to enable the lower polishers to engage the lower work rolls respectively;
- and
- simultaneously polishing the upper and lower work rolls during the rotation of the upper and lower work rolls.
