How to choose furnace type for metal heat treatment?

The furnace type should be determined according to different process requirements and the type of workpiece

1. For those that cannot be produced in batches, the sizes of the workpieces are not equal, there are many types, and the process requires versatility and versatility, box furnaces can be used.

2. When heating long shafts, long screw rods, pipes and other workpieces, deep-well electric furnaces can be used.

3. For small batches of carburizing parts, pit gas carburizing furnaces can be used.

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

5. Rolling furnaces and roller-hearth furnaces are better used when heating the sheet blanks of stamping parts for mass production.

6. For batches of shaped parts, push rod type or conveyor belt type resistance furnaces (push rod furnaces or cast belt furnaces) can be selected for production.

7. Small mechanical parts such as screws, nuts, etc. can be used in vibrating hearth furnace or mesh belt furnace.

8. Steel balls and rollers can be heat treated with an internal spiral rotary tube furnace.

9. Non-ferrous metal ingots can be produced in mass production using pusher furnaces, and small non-ferrous metal parts and materials can be air-circulated heating furnaces.
