Furnace type should be chosen according to different process requirements and types of parts.

1. For those parts that cannot be produced in batches, different size and types, box furnace can be selected.

2. To heat parts with long shaft, long screw rods or pipes, deep-well electric furnaces are optional.

3. Gas carburizing furnace can be used for small batch carburizing parts.

4. Continuous carburizing production line or box multi-purpose furnace can be selected for large quantities of automobile, tractor gear and other parts.

5. It is better to choose rolling furnace and roller hearth furnace when heating the blanks of stamping parts in mass production.

6. Push-rod or conveyor-belt resistance furnaces are optional for batches of shaped parts.

7. Small mechanical parts such as bolts, nuts, etc. can use vibrating bottom furnace or mesh belt furnace.

8. Internal spiral rotary tube furnace can be used for heat treatment of steel balls and rollers.

9. To produce mass production of non-ferrous metal ingots, push-rod furnace can be used, while air circulating heating furnace can be used for small non-ferrous metal parts and materials.
