To protect the muffle, a muffle furnace usually stays powered on at all times.
Gas consumption depends on the furnace sides, as well as the oxygen content requirement. When the furnace is not working with a load (during night shift, for example) the gas flow can usually be turned down to 30% - 40% of the working rate.
With an optimized structure and superior insulation design, our furnace is energy efficient. After reaching the required profile, the heating elements will work at about 50% or less of the maximum power output. This extends the lifespan of heating elements, and saves power. When the furnace is not working with a load, the insulation power of empty furnace is usually 20% - 35% of the max power output.
Typical spare parts include a belt, a brush, a Solid State Relay, a cooling fan, a thermal couple, heating elements, et cetera. Under normal working condition, our furnaces can run 3-4 years without needing any major parts replaced.
The following elements must be ready before the belt furnace can be installed:
Our engineers will issue clear instructions on this preparation beforehand.
Yes. A hearth plate with walls can be incorporated within the furnace. The belt would travel through the furnace on a metal hearth plate with side walls, which would prevent products from falling off the belt.
- Direct controllers on the furnace will offer basic control of parameters, such as zone temperature, belt speed, et cetera.
- A Windows-based industrial computer control system allows for easy profile setting, storage of multiple profiles, an straightforward working status monitor, and easy access to all operating data history.
- Beckhoff embedded control systems are suitable for customers that require a Beckhoff embedded control system.
Nitrogen is most commonly used for a gas curtain. It is inert, safe, and effective in keeping air out of the furnace. Additionally, the cost is relatively low.
FEC stands for Fully Enclosed Coil, which means that the heating wires are embedded within the ceramic fiber boards. This design protects the heating wires, and also provides power distribution evenly in order to maintain the temperature uniformity.
Alumina silicate fiber is a high performance insulation material commonly used in our furnaces. It has small density, as well as good energy saving performance.
Usually, the cooling water needs to meet requirements for pressure. Also, a proper corrosion inhibitor must be added.
