Working on the design of an electric furnace used to fire glazes and enamels at 700-900 degrees °C. The requirement is that the temperature is homogeneous throughout the working area within +/- 4 °C. It will operate as a batch furnace, and the temperature-time profile must be well controlled - I need to be able to ramp up from room temp to 850 C in less than 20 minutes. I need a working volume of 2 X 0.8 X 6 meters.
Ceramic fiber boards for insulation seem to really help with rapid temperature ramp ups, but from what I've seen tend to have less than acceptable temperature homogeneity.
All suggestions, ideas, and critiques are welcome, and it seems that possibly a continuous furnace might be the proper way to go.
