programming oven for simple carbon steel?

Well Paragon has been no help in figuring out why my furnace has never worked right (got it brand-new, directly from them) so I got ahold of an approved service shop in Portland.

The fellow I spoke with, Mitch, was very helpful and nice to chat with. He mentioned something about programming an adjustment in temperature for when the blades are put in.

Color me ignorant, but if I'm putting a W2 blade in at 1450, shouldn't I just be able to program it for 1450 at say an hour or so hold time so that the oven ramps up, I put the blade in, let it get back to temp, soak a few, and..... ???

Seems ridiculously simple to me, that's how I've always done it in the salt bath, but am I overlooking something with the programming?

I'm taking the oven to Mitch today to have him figure out what's up with it. It will be nice to get actual use out of a $1500 tool that's been in my shop for about 4 years. :eek: :rolleyes: :grumpy:
 
Nick, I've never heard of an adjustment for putting blades in. :confused:

With my old homebuilt and with the Evenheat, I just set the temp, set rate (usually 9999 on the EH which is max), set the soak, and away we go. When it's heat soaked, I pop the blade in, let the oven even out the temp, and then soak for however long I need.

The controller shouldn't know the difference between having a blade in or out. It should just be worried about reaching and maintaining the target temp.

Nick I have two paragons and I do exactly as you have said. program the alarm for your set temp and you know when to start timing your soak.
 
Thanks Nathan... seems it should be just that simple. Wondered if I was overlooking something.

This guy seems to be real helpful, so I'm excited to get the damn oven firing properly!!! :)

Thanks Mike and Bill. Guess I just got a dud.... hopefully they can get me fixed up :)
 
Nick,

I've got an Evenheat that may do something similar.

Say I program for 1500 degrees and 1 hour hold time.

If I wait till it hits 1500 then open the door to put in the blade sometimes I'll get an error code that will stop the program. (If the temp goes too low under the set temp it will get the error)

My solution is to set the alarm to 1475 then put the blade in before it ever reaches target temp. Then the programmer doesn't recognise the drop, only that it's still trying to reach the target temp.

I do know that you can program the error codes to off and I'm pretty sure you can change the amount of temp. it takes to set off the error code.

Again this is an evenheat with a Rampmaster controller but it sounds like a similar situation.

im jsut as simple with my even heat
never got an error loading even 6 razors as part of a normalizing set

Now that's funny right there... :D

When I visited your shop last year, I was just starting to get interested in acquiring a HT oven. I remember seeing that Paragon at the far end of the garage with a ton of junk piled on top :confused:. You mentioned that you didn't use it much. I didn't know it was because it was TU... Just figured you went 100% salt.

I love my Sugar Creek. I have one program... ramp up to 1200F for 1-hour, then ramp up to 1495F for one hour, then off. Pretty simple... just a lot of in-and-out during that time.
 
I am not saying that heat treating is a piece of cake but I felt alot more confident in using my oven when Kit told me "I am glad your learning your own heat treat. Its just heating up and cooling anyways."

Dont let that guy over complicate it.

Nick - I had a view of your avatar for a 3 month period while looking for a job in Oregon. Back in NC now though :)
