Hi all,
I resently purchased an Evenheat KF22.5 with a Ramp master control. I have had a couple if bad goes heat treating O1 and 4140. The just didn't get hard. I have done some tests with an infrared temp gage, and discovered the botom of my oven is about 200 degrees lower than the top next to the thermocouple. My infrared tester only goes to 999 degrees, but I do see a pattern in my tests. Have any of you had similar issues and what have you done to compensate? I was thinking about building a fire brick platform to get my blades up near the top of the kiln. Right now I just have the knife fixture Tracy sells on the floor of the kiln.
