Start Your Furnace Project with 6 Questions

The photo below shows the control panel of a customized furnace. It is for our customer doing metal annealing process in Europe. Like many customized equipment, there are a lot of details to consider when it comes to the entire design of a belt furnace system. The following 6 questions are good ones to start with.

1)What is the application?
Some common applications are thick film firing/drying, paste drying, glass to metal sealing, solar cell processing, soldering, brazing, sintering, annealing, curing.
2)What is the product material, dimension, weight? What carrier do you use to hold the products in the furnace?
This will help decide the belt loading capacity, chamber dimension, driving power, how easy it can be heated or cooled.
3)What is the desired productivity?
This will help the design of furnace length, belt width, belt speed.
4)What is the time-temperature profile?
This will help design the heating zones, cooling method(air cooling or water cooling).
5)What is the atmosphere requirement?
Common atmospheres are air, N2, Ar, H2, O2.
6)What is the footprint limit(max length/width of the furnace)?
This will ensure the furnace can fit the facility.
The root of a perfect design lies in the good communications between designers and end users.
