Inserting Work-Pieces for Heat Treating
Before immersing any work-piece, hangers, tools etc. into the salt bath be sure that all items are entirely clean and free of any grease, oil, water, moisture or other
contaminants. Eruption of the molten salt is possible if contaminants are introduced into the molten salt. This eruption/explosion presents fire and burn hazards as
well as potential injury or death. Playing safe and making cool stuff is the goal.
Generally work-pieces are suspended within the salt bath via various hanging methods. The most common appears to be steel wire. Whatever suspension method
you do decide on it must be made of steel. We would mention that we are not aware of any useful technique that simply places the work piece into the salt bath
without a secured means to retrieve it. Work-pieces may be fully immersed or partially immersed depending upon your heat treating needs. We recommend using a
suspension method that prevents the work piece from falling to the bottom of the salt pot.
Your heat treat process will determine the amount of time the work-pieces remain in the salt bath. The TAP control features an elapsed time clock that is very useful
in keeping track of your immersion time.
Below are some images taken during our design and testing process in cooperation with Tim Zowada of Tim Zowada Custom Knives in Boyne Falls Michigan that
illustrate his preferred suspension technique.
