DIY Heat Treatment Oven

Показать описание

Finally made a proper heat treatment oven capable of reaching 1000°C (1800°F) drawing "only" 1.7kW.

Links to amazon products can be found here in my affiliate store:
Components list:
Isulating bricks J23 rated to 1260°C. (230x110x64mm).
Premixed refractory mortar.
Kanthal A1 wire 20ga (10m).
PID controller.
K-Type Thermocoupple rated to 1250°C.
Solid state relay with heatsink.
12V computer case fan with power supply.
Random steel pieces from the steel scrapyard.

The Kanthal wire I bought is meant to be used in vape pens and has a resistance (R) of 30Ω for my lenght and thickness.
The power draw can be calculated knowing the home mains voltage (225V in my case).
Power draw: P = V x I
Where I is the current flow in ampere: I = V / R = 225 / 30 = 7.5 A
P = 225 x 7.5 = 1687.5 W

Control box designed in Fusion360 and printed with PETG.

Inside dimension are 105x115x450 mm (4x4.5x17.5 inch).
I made the oven this small so that it's easier to heat up and there is no need for more heating element, considering also that my home has a power draw cap of only 2kW.

Now it's time to work some stainless steel!

Curios about specification for this oven? Check the video description! And while you are there check out my Patreon page too for early access and a voice-over edit of my videos. If you like what I do consider supporting me so I can keep on making:

I see more safety concern than usual, let me address some!
The frame is grounded and all connection are nice and tight.
Someone suggested a door switch to cut power to the heating element with the door open, I will do it asap.
Some sort of box around the heating element terminals would be better too.
Anyway, I'm the only one using my homemade tools so I'm not worried at all even as is!!
Thank you all for the suggestion and preoccupation. Be safe :)

Things like this are why I enjoy the 'Net...a self-taught Italian fellow showing how he constructed something useful that anyone can copy for themselves.

I have had heating coils break on different things like hairdryers and the such. The hole through the bolt connector you made had never crossed my mind to do. I live with 3 daughters and a wife which means we have a budget item for at least 3 to 4 hair dryers a year.
90% of them fail at the rivet connection at the board. Thanks for the fix.

Every design you share with the subscribers demonstrate your capabilities and ingenuity, thank you and have a nice day.

Safety is first, please add some isolation to points where cables are connected to heat element, it's outside under Rest of the
project super ;)

WOW, I searched for a proper heatment oven for a long time and that is my absolut favourit!
Came here for your stabilized cork video, but that oven is seriouly the thing i will build first!!
Congrats, your channel is amazing, cant wait for more!
Greetings from Germany ;)

Well I am speachless! I m kind of hypnotized watching your creations you are the modern version of Leonardo Da Vinci!

So many makers are going to copy this project! Complimenti!

Thank you, for putting this and your other videos on the internet.

That was absolutely great! I meant to make one for really long... bravissimo!

Absolutely fascinating, bro. I wish you gave a few more details on the heat control and exhaust fan that you installed. Also, the insert you made on top of the oven. Thank you so much for this.

I really appreciate this video. This oven could be built for a fraction of the cost. Thanks so much!

It's cool but a pizza doesn't fit in there.

I really like that. I've got a spare couple of PIDs here somewhere and some thermocouples and RTDs. If I ever get on top of my health problems, I should throw one of those together. (A lot of things I need to do if I ever get better)
Nice work.
