Hello. I have built an electric tube furnace using nichrome wire, an AC contactor, and an Auber Instruments SYL-2342P PID controller. I have the basics of programming it figured out but the furnace can never get above 1525 F before the controller switches to "stop" mode. Here is my program: C01->50 t01-> 90 C02-> 1825 t02-> 15 C03-> 1825 t03-> -121 The furnace heats up no faster than about 1-2 F per 5 seconds. What am I doing wrong? Is there a setting that is triggering the shut-off prematurely? Any help would be appreciated.

I gave up on LPG or propane about 10 years ago in favor of diesel. Diesel is cheaper and easier for me to store and doesn't suffer from 'freezing' issues . When I was a boy, I had to light diesel furnaces every morning. In exploring diesel as an alternative I hunted high and low for the burner design I had seen in use in industry. I finally tracked it down to a New Zealand patent from 1936. I scaled my rough drawings from the patent , producing this 'prototype' ( never stopped using it) and several larger burners for other furnaces. These burners require a little bit of skill to set up and run

So as of late while gallivanting around the site, I stumbled upon the concept of "Aristotle's Furnace", so I got to thinking; I'm an amateur with some free time coming up due to fall break, I have an excess of clay that I processed, and I have a passion to make some good steel. So the thought occurred to me that rebar could perhaps be a cheap alternative that is readily available and can be cut into bits and melted down in the furnace. I am even thinking of making my own charcoal for this project. Does anyone have any other suggestions for cheap, readily available iron or steel sources? Also y

Hey everyone! This is my first post, and I am making it as I ramp up towards my first smelt. I have been going over the posts here and have been able to get a lot of the details of my first smelt down, like ore type, flow rates, charcoal creation, furnace design, etc... What I haven't seen though is any talk about the internal pressure of the furnace and what effect it has on a bloom. I was thinking of modifying one of the Rockbridge furnaces to increase the internal pressure as a way of increasing the temperature. Has anyone tried doing this? If so, was it helpful? Hurtful?
