Half furnace desktop-small size melting furnaces
◆ Small size furnaces have to match with frequency isolated converter to improve efficiency.
◆ Suitable for using with stainless steel, alloy, super alloy, cooper and aluminum…etc.
◆ High frequency isolated converter used to Duplex insulation for electricity.
◆ The furnace is able to melt different metal as the refractory is substituted.
◆ Allows recycled materials to save cost.
◆ High heating speed leads to fast melting, with low alloy oxidation loss.
◆ Electromagnetic wave stirrer blends the molten alloy evenly.
◆ The melt temperature can be controlled through the adjustment of electric power according to the casting melting condition.
◆ Using induction current to heat up and melt the metal directly causes lower operation temperature to the operating environment.
◆ Not having to keep melting remainder in the furnace makes it easy to switch between different materials.
◆ The system can be intermittently or immediately re-operated with cold materials.
◆ No air pollution since no coal or fuel.
Non-contact SCR switch
- DC power supply is controlled by fast response non-contacted SCR, power supply will be cut off in 8.3ms when extraordinary issues are detected.
Redundant breakers and protections
- Fast response circuit breakers on main equipment. ON-OFF power supply without sparks.
- High speed cutoff at over current or low voltage.
Intelligent power control
- Autocorrecting the input power according to the condition of the material offers a higher overall efficiency.
- Saving energy costs without effecting productivity.
Multiple monitoring systems for protection
- Power limit stepless control.
- Power current monitoring and maximum power limit.
- The power supply will be cut off automatically by SCR switch when the voltage, current or TOT exceeds the safety value.
- There are 18 signal indicators on the control panel, and each PC board also has its different signal indicator to show the running condition of the equipment, which makes it easier to troubleshoot.
Leak current test of molten metal
- Use galvanometer to detect the leakage of electricity outsize of the refractory lining and show the value on control panel directly.
- Equipment will automatically be stopped with an indicating signal when leakage exceed the preset value allowed.
