So this is a start for a small electric oven / kiln..
I have 3, 5kW heating elements and a pid, k-sensor and a 3 phase relay from ebay lying somewhere i will be using for this..
The frame is just welded up from 20x20x3 steel profiles, And the bricks is the standard fireproof 25mm thick fireplace bricks you find in the woodstore.. They are rated for 1380C.. and i aim to run this oven to max of 900C.. Its main purpose will be heating steel for quenching in a safer manner than i used to do it.
Im gonna try to find some superwool or kaowool for the inside of it or i will just go with rockwool on the outside of it (not the best choice but it works kinda good actually. Best if a kaowool lining could be put in place and rockwool on the outside as well.. That would probably be the best combination of insulation.
Anyway, images..
