Roll Set Job Program for Production Three Roll Mills
|
The description as to what is included in our Roll Set Job is given below (Items #1 to #14). Please inquire for pricing.
- The roll set is brought into our shop and it is disassembled to parts. All parts are then inspected so that we can prepare a specific quotation. This quotation will outline the work that we intend to do, the parts, (if any) that are required, and our estimate as to the charges involved. This is part of our standard charge.
- All castings go into our heated and agitated cleaing tank, and once these are down to bare metal, these are then primed and painted. This is part of our standard charge.
- The roll interiors are inspected to check for scaling, the interior water pipe indent is drilled out to insure proper fit, and the roll interiors are chemically cleaned. This is part of our standard charge.
- Two new bearings are supplied for the apron roll. This is part of our standard charge. All other bearings are inspected for wear and replaced as required. We recommend replacing all bearings, but some of our customers only want to replace worn bearings, and of course, they are given this option. Replacement bearings for the center roll and feed roll are at additional charge.
- The bearing journals are inspected and brought back to new specifications, as required. This is part of our standard charge.
- The rolls are ground on our roll grinders. Our customers normally leave the crown specifications to our expertise. On the other hand, we can, of course, crown to customers specifications. This is part of our standard charge.
- The roll bevels/undercuts are machined to insure that all rolls match. This is part of our standard charge.
- The gears are topped off and recut as required to conform to the new roll centers. This is part of our standard charge. If new gears are required, these are manufactured to suit, and this is at additional charge.
- The endplates are milled, retipped and then remanufactured to conform to the new roll centers. Endplates for Day mills get new two pieces and scrapers. Plates for Lehmann mills get toe pieces only. This is part of our standard charge.
- The bearing box seals are replaced as required. If the bearing box covers have the old style felt seals, they are machined to accept the standard seals. Both of these items are additional cost items.
- A new set of water pipes is manufactured and supplied. This is part of our standard charge.
- The roll set is then reassembled. It is then installed on a mill frame, and quality assured. After our quality assurance check, the roll set is then prepared of shipment. This is part of our standard charge.
- When a roll set is sent into us for a Roll Set Job, we recommend that the apron be sent into our shop also. If we do receive the apron, it is inspected to see if it needs simple service or a complete apron overhaul. The inspection is part of our standard charge. The recommended repairs, if required, is an additional charge.
- We endeavor to use the roll crates sent into us for the return trip. If crating is required, this is an additional charge.
