(3) and after the workpiece is heated, the furnace door is reversely moved along the linear guide rail, and then the workpiece is taken down from the workpiece mounting mechanism.
10. The use method according to claim 9, wherein in the step (1), the workpiece is mounted on the workpiece mounting mechanism by the following specific steps:
1) firstly, the distance holder is installed: the comb-shaped positioning plate penetrates through shaft holes of a plurality of sheet-shaped annular workpieces, and one sheet-shaped annular workpiece is placed at the comb-shaped interval of the comb-shaped positioning plate; then, a second adjusting bolt is rotated to drive the comb-shaped clamping plate to move, so that the comb-shaped clamping plate and the comb-shaped positioning plate are relatively displaced, and the sheet-shaped annular workpiece is clamped; then a pressure lever is installed, a fastening screw penetrates through the fastening groove, and a fastening nut is screwed tightly;
2) after the distance holder is installed, the distance holder is hung on the hanging rod through the hoisting equipment.
