|
|
- **[Core]** Install equipment such as guides, guards, gears, cooling equipment, and rolls, using hand tools.
|
|
- **[Core]** Signal and assist other workers to remove and position equipment, fill hoppers, and feed materials into machines.
|
|
- **[Core]** Calculate draft space and roll speed for each mill stand to plan rolling sequences and specified dimensions and tempers.
|
|
- **[Supplemental]** Select rolls, dies, roll stands, and chucks from data charts to form specified contours and to fabricate products.
|
|
- **[Core]** Activate shears and grinders to trim workpieces.
|
|
- **[Supplemental]** Remove scratches and polish roll surfaces, using polishing stones and electric buffers.
|
|
- **[Supplemental]** Disassemble sizing mills removed from rolling lines, and sort and store parts.
