Aluminium Scraps Recycling Melting is the process by which scraps aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al2O3), which must first be mined from bauxite ore and then refined using the Bayer process. Recycling scraps aluminium requires only 5% of the energy used to make new aluminium from the raw ore. For this reason, approximately 36% of all aluminium produced in the United States comes from old recycled scrap. Used beverage containers are the largest component of processed aluminum scraps, and most of it is manufactured back into aluminium cans.
HLQ Induction Equipment Co provides the leading
Aluminium Scraps Recycling Melting Furnace for recycling aluminium Scraps/cans/ingots and dross for industry aluminum recycling filed.
Operation Steps:
- A Aluminum scraps/ingots/cans recycling furnace operator will place aluminum parts or aluminum ingot/scrap as a charge in the induction melting aluminum recycling furnace and start the furnace to begin the melting process. Adding more aluminum charge this process is advisable as molten aluminum transmits the heat better.
- When temperature of the aluminum reaches 1220.66°F it turns to liquid. Any residue from the coating and paint from the cans will float on the surface. This byproduct is called dross and can be skimmed by a steel ladle. This needs to cool before it can be disposed off safely.
- Next, the crucible (furnace) will pour out pure aluminum. Usually, Hydraulic tilting mechanism provided to pour large quantities of liquid metals.
- Finally, with care, the molten aluminum will be poured into mould to cool down and then slide out for use.
Advantages of induction aluminum scraps recycling furnace:
1, save energy and reduce the environmental temperature
Original diesel furnace workshop on pollution, but also the auxiliary exhaust pipeline, inside and outside the furnace heat has a large number of distribution in the workshop, resulting in high temperature workshop. So is the original furnace condition, most escapes to the air, there is heat conduction loss, the production of large power consumption, increase the cost of production. At the same time, the ambient temperature increases. The electromagnetic induction heating process, the heating element is through magnetic field heating, in order to reduce the loss of heat conduction, fast heating, melting rapidly, thus reducing energy consumption. Reduce electricity consumption. After the comparison of the experimental test and modification, the power saving effect is 20%-40%.

Electromagnetic induction heating method is through the magnetic field lines make heating rapid heating, the rapid melting Aluminum Alloy. The temperature control is real-time and accurate, which improves the quality of the product and improves the production efficiency!
3 and long service life, simple maintenance
The traditional electric melting induction furnace heating method is to use resistance wire heating, resistance wire in the high temperature environment for a long time in the use of oxidation will result in reducing its service life, high maintenance costs. The electromagnetic heating coil is made of insulating material and high temperature wire, so the service life is long and without any maintenance.
4, power
Electromagnetic induction heating with the development and maturity of the technology, the production process and technology of components, software, such as reliable protection of the current power can be 2-200KW.
5, safe
The utility model adopts the electromagnetic induction heating, which can reduce the surface temperature of the machine, and the human body can be safely touched, so as to avoid the occurrence of burn and scald accidents caused by the traditional heating mode and protect the production safety of the employees.

Induction Brazing Basics for jointing copper,silver,brazing,steel and stainless steel,etc.
Induction Brazing uses heat and filler metal to join metals. Once melted, the filler flows between close-fitting base metals (the pieces being joined) by capillary action. The molten filler interacts with a thin layer of the base metal to form a strong, leak-proof joint. Different heat sources can be used for brazing: induction and resistance heaters, ovens, furnaces, torches, etc. There are three common brazing methods: capillary, notch and moulding. Induction brazing is concerned solely with the first of these. Having the correct gap between the base metals is crucial. A too-large gap can minimize the capillary force and lead to weak joints and porosity. Thermal expansion means gaps have to be calculated for metals at brazing, not room, temperatures. Optimum spacing is typically 0.05 mm – 0.1 mm. Before you braze Brazing is hassle-free. But some questions should be investigated — and answered — in order to assure successful, cost-effective joining. For instance: How suitable are the base metals for brazing; what’s the best coil design for specific time and quality demands; should the brazing be manual or automatic?

A source of high frequency electricity is used to drive a large alternating current through a induction coil. This induction heating coil is known as the work coil. See the picture opposite.
The passage of current through this induction heating coil generates a very intense and rapidly changing magnetic field in the space within the work coil. The workpiece to be heated is placed within this intense alternating magnetic field.
Depending on the nature of the workpiece material, a number of things happen...
The alternating magnetic field induces a current flow in the conductive workpiece. The arrangement of the work coil and the workpiece can be thought of as an electrical transformer. The work coil is like the primary where electrical energy is fed in, and the workpiece is like a single turn secondary that is short-circuited. This causes tremendous currents to flow through the workpiece. These are known as eddy currents.
In addition to this, the high frequency used in
