Heat Treating Program Example
Below is a typical 3 step firing schedule for Heat Treating Steel.
Step 1. Heat as fast as possible from starting temperature to 1800°F, Hold
at 1800°F for 20 minutes
Step 2. Cool as fast as possible from 1800°F to 400°F, with no hold time at
400°F
Step 3. Heat as fast as possible from 400°F to 500°F, Hold at 500°F for 5
hours, and then Shut-off
To program this schedule from IdLE mode;
1. Press (Program) button. The controller will display the last active
program that was used. PrO1 – PrO9
2. Press (Program) button again if you want to use the same program that
is shown or press (Increase) button to change to another program and
then press (Program) button again.
3. Program the steps below and press (Program) button after each segment.
