- 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, between the upper and lower work rolls, at a position under the lowest point of the upper work roll and above the highest point of the lower work roll, wherein the polishing apparatus includes polishers configured from substantially rigid concave pans which can be simultaneously aligned for engagement with respective work rolls to simultaneously polish each of the 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 the upper and lower work rolls 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 upper and lower work rolls of a metal leveler through the use of a polishing apparatus, the method comprising:
- configuring the leveler in an open position;
- inserting said polishing apparatus into the leveler, between the upper and lower works rolls, at a position under the lowest point of the upper work roll and above the highest point of the lower work roll, 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 the work rolls within the polisher pans.
A method for polishing the work rolls of a metal leveler through the use of a polishing apparatus, the method comprising:
- 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, said step of inserting the top and bottom polishers into the leveler comprises using an air motor to move the polishers relative to a table support and inserting the polishers between the upper work rolls and lower work rolls of the leveler;
- juxtaposing the polishers and the upper and lower work rolls of the leveler by extending the polisher to further contact the work rolls, during the rotation of the work rolls,
- rotating the work rolls to polish the work rolls within the polisher pans.
A method for polishing the work rolls of a metal leveler through the use of a polishing apparatus, the method comprising:
- 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, in which the step of extending the polishers comprises using an air motor and a valve to inflate and adjust internal air bags within the polishing unit, in order to cause the polishers to contact and polish the work rolls;
