Melting Furnace Non-contact Style
PERMANENT MAGNET TYPE ALUMINUM CHIP MELTING SYSTEM
Advantages of molten metal agitation
Improvement of molten metal quality
Homogenization of molten metal components
Powerful circulation makes the adjustment of composition easy.
Component segregation can be adjusted extremely small for both circumferential direction and depth direction.
Perfect for use as a furnace for the adjustment of composition of molten metal
Homogenization temperature (±2℃) of molten metal
Heat transfer volume from the burner is improved by circulation function. Molten metal temperature can homogenize for both the circumferential direction and depth direction.
Improvement of yield rate (98% or more)
Charged melting materials of vortex chamber can keep 98％ or more yield rate because materials will be convoluted at once into molten metal without oxidation.
Improvement of energy consumption
Gas consumption is cut by 20％ by homogenization of molten metal temperature and atmosphere temperature. (Comparison with our products)
Inhibition of oxide generation
Generation of oxide can be inhibited. (Homogenization of molten metal temperature can prevent overheating of molten metal and therefore inhibit molten metal oxidation.)
Long operation life of refractories
Refractories can be long operation life. (Homogenization of molten metal temperature can prevent overheating of molten metal and therefore inhibit refractory reduction.)
Purpose
●Melting of aluminum chips, machining chips, UBC and solid biscuit
●Powerful circulation makes the unit perfect for use as a furnace for the adjustment of composition of molten metal.
- ●Circulation power can control stepless adjustment and maintain stable power.
- ●Continuous melting and unmanned operation is possible.
- Materials can be melted continuously without need for monitoring operators.
- ●The molten metal agitation unit can be installed as an extension for the existing melting and holding furnace.
Cost performance of aluminum chip reclamation with our permanent magnet type aluminum chip melting system
*The numerical values below are approximate calculations and will differ according to conditions of customer use.
| Processing volume | ||
|---|---|---|
| 300kg/hr（1,150ton/year） | 500kg/hr（1,920ton/year） | |
| Comparison with reclamation ingot purchase | ¥60,700,000/year | ¥148,400,000/year |
| Comparison with molten metal purchase | ¥83,700,000/year | ¥186,800,000/year |
Comparison with traditional chip melting system
Unnecessary spare parts (consumable goods) and maintenance work
Electromagnetic induction agitation system requires spare parts including water cooling device, coil
etc. and maintenance work. Machine agitation system requires spare parts including impeller, pump
etc. and maintenance work.
Power consumption about 1/10 (Compared with electromagnetic induction agitation system)
Molten metal circulation can be trouble-free operation at the touch of a button thanks to the simple configuration.
Smaller footprint
About a 50％ reduction in footprint size is possible because our heating and holding chamber has concomitant vortex chamber only. (Compared with electromagnetic induction agitation system or machine agitation system)
