Medium Frequency Induction Melting Furnace for Gold, Iron, Silver, Bronze, Stainless Steel

Brief Introduction:

Apply big power high frequency induction heating system to melt gold, K-gold, silver, brass, etc. High frequency power not only provides fast melting but also electromagnetic mixing function which helps making highly even metal liquid.

I. Operation:

Power on →open water faucet → put ceramic crucible in the machine→put metal in the crucible→press heating switch→press stop switch→tongs the crucible and pour the metal liquid.

II . Attention:

1. Can’t be water-break during using the machine. If happens by accident, it needs to pick up the crucible at once, or the copper ring will be burnt out.

2. Don’t press the heating switch without crucible.

3. Press stop switch first, then pouring the liquid after the metal melted.

4. If the work is finished everyday, please take away the crucible then shut off power.

5. When water flow indicator light is shut off, it stands for out of water or low water pressure. And now the machine will start the function of protection, the machine will stop heating.

III. Technical Parameters:

Model HJ-1106D

Induction Heating FAQ'S

What is induction heating?
The heating method known as induction heating occurs when an electrically conductive material is placed in a varying magnetic field. Induction heating is a rapid form of heating in which a current is induced directly into the part being heated. Induction heating is a non-contact form of heating.

What makes up a typical induction heating system?
A typical induction heating system consists of the induction heating power supply, an induction heating coil, and a water-cooling source, which cools the coil and several internal components inside the power supply. The induction heating power supply sends alternating current through the induction coil, thus generating a magnetic field. When a work piece is placed within the coil and enters the magnetic field, eddy currents are induced within the workpiece, generating precise and localized heat without any physical contact between the induction coil and the work piece.

What is an induction heating coil (inductor)?
The varying magnetic field required for induction heating is developed in the induction heating coil via the flow of AC (alternating current) in the coil. The coil can be made in many shapes and sizes to custom fit a specific application. The coils can range from tiny coils made of copper tubing used for precise heating of extremely small parts in applications such as soldering and ferrule heating to large coil assemblies of copper tubing used in applications such as strip metal heating and pipe heating.

What is the importance of the induction heating coil (inductor)?
The induction coil design is one of the most important aspects of an induction heating system. The coil is a custom design to give your work piece or part the proper heating pattern, maximize efficiency of the induction heating power supply’s load matching system, and to accomplish these tasks while still permitting ease of loading and unloading your part.

How can my process benefit from induction heating?
Induction heating can benefit your process in a number of ways. Induction heating is highly repetitive once initial adjustments are made to the power supply. Following this phase, part after part can be heated with identical results so long as the parts are introduced to the coil similarly each cycle. This can also lead to better material utilization and product yield. Induction heating can reduce or eliminate the need for skilled operators in application such as brazing and soldering. The ability of induction heating to heat all parts identically lends itself to automation of the process. Induction heating can also heat the part in a highly localized fashion, which can be extremely beneficial when it is desirable or necessary to limit the heat to only a certain region of the part.

How does induction heating equipment compare to other heating sources?
In addition to some of the points mentioned in the previous FAQ, induction heating is also a clean form of heating which does not emit unpleasant odor or heat. Because the current is induced directly into the part being heated, there is no radiant heating effect into a facilities ambient environment. The location of the desired heat zone can be defined to a specific area on a workpiece in order to achieve accurate and consistent results. Induction heating equipment is instantly on which means it requires no warm-up time as other conventional heating sources do. Induction heating systems are extremely energy efficient.

What is the importance of a power supplies power rating and frequency?
The power rating determines the speed at which a workpiece can be heated. The frequency, along with the electrical resistivity of the workpiece and relative magnetic permeability, determines the skin depth of the eddy currents induced into the work piece. In surface heating, the power rating also plays an important role in skin depth. The higher the frequency, the more shallow the skin depth and the lower the frequency, the deeper the skin depth. Therefore, higher frequencies are more effective for heating smaller parts or parts that require shallow heat penetration, while lower frequencies are more effective for larger materials with deeper heat penetration requirements.
