How can I prevent the furnace from smoking?

How can I prevent the furnace from smoking?

How can I prevent the furnace from smoking?

(OP)
Hi Guys!

We temper our parts after oil quenching. The furnace that tempering happens in provides a lot of smoke once the operator opens the door. The hole building gets all cloudy all day and the smoke&smell give the other operators headache.

Does anybody know what might cause that and how I can solve this problem?

Thanks!

RE: How can I prevent the furnace from smoking?

The oil left on the part surface was during during the tempering heat treatment. Can the tempering equipment add a range to collect smoke?

RE: How can I prevent the furnace from smoking?

Almost all furnaces and ovens should have a hood over them so fumes are exhausted outside. This is basic for heath and safety of workers. It seems you also need better ventilation of the building.

RE: How can I prevent the furnace from smoking?

The tempering furnace is a poorly designed one, as it does not consider fume extraction. Hope, you get it installed, as suggested by other members too.

RE: How can I prevent the furnace from smoking?

If oil carry over is a big issue you could clean the parts.
We used to blast with wet steam and then tumble in corn cob meal.
But furnaces should have hoods and vents, especially if they are combustion furnaces.
Even without the oil you don't want products of combustion inside the plant.

All of our parts are washed following quench and before temper. There will be a bit of leftover material that gets burned off however. You should have a hood over the temper door to pull air out of the area.

White Paper - Design for Additive Manufacturing
With a growing number of parts manufactured directly by additive manufacturing techniques, it is important to lay down design principles suitable for such manufacturing processes and to ensure parts are designed for additive manufacturing. There are several factors that are to be considered at the design stage. Few such design issues in additive manufacturing are discussed in this paper. Download Now
