What is the difference between a heat treater and a furnace operator?
A furnace operator…
- Follows work instructions
- Loads and unloads furnaces
- Enters programs and setpoints in furnace controls
- Periodically monitors furnaces for proper operation, soak times, soak durations, etc.
- Contacts a heat treater when there is a problem
A heat treater can typically do all of the functions above and also...
- Writes work instructions
- Can engineer a process for a specific part/material (including pre and post-heat treating)
- Optimizes load configurations
- Supervises furnace operators
- Can troubleshoot a process or a furnace when there is a problem
- Keeps his cool under pressure and knows how to recover from unexpected occurrences
Both of these types of individuals are critical to the success of our heat treating facilities. However, with more modern controls and equipment, along with more sophisticated quality systems, it would seem that more people at the shop level are being trained and used as furnace operators. With these new controls and quality systems, will they ever be able to develop into heat treaters?
It can surely be argued that taking the “tribal knowledge” out of the salty dog’s pocket notebook and putting it on a heat treating work instruction was a good thing. However, what happens when something goes wrong (power interruption, jammed load, stuck inner door, unexpected hardness results, etc.) and an experienced heat treater is nowhere to be found? The best and safest recovery for every situation can’t be written on a work instruction. It is training and experience that will save the day (and the customer’s parts) when these situations occur.
The industry needs to continually offer training opportunities to furnace operators so that each of them can eventually become heat treaters themselves.
