Selection of commonly used furnace types for heat treatment of shafts

The furnace type should be determined according to different process requirements and workpiece types.

1. For workpieces that cannot be produced in batches, have unequal sizes, and have many types, and require universality and versatility in the process, a box type furnace can be selected.

2. When heating long shafts and long screws, pipes and other workpieces, a deep well electric furnace can be selected.

3. For small batches of carburized parts, a well gas carburizing furnace can be selected.

4. For large-scale production of automobile and tractor gear parts, a continuous carburizing production line or a box type multi-purpose furnace can be selected.

5. For mass production of stamping parts, it is best to use a rolling furnace or a roller hearth furnace.

6. For batches of fixed parts, a push rod or conveyor belt resistance furnace (push rod furnace or casting belt furnace) can be selected in production.

7. Small mechanical parts such as screws, nuts, etc. can be selected with a vibrating bottom furnace or a mesh belt furnace.

8. The heat treatment of steel balls and rollers can be carried out in a rotary tube furnace with an internal spiral.

9. Pusher furnaces can be used for large-scale production of non-ferrous metal ingots, while air circulation heating furnaces can be used for small non-ferrous metal parts and materials.
