How Does Gold Melting Induction Furnace Melt The Metal?

Gold induction melting furnace is usually accomplished with heating the metal in a crucible. It is made from a non-conductive refractory material. The metal inside crucible will melt into the liquid form.
Typically, the process used to produce high-quality steel or non-ferrous alloys for casting operations. Thereafter, the liquefied metal is poured into a cavity having a desired shape. The metal solidifies with minimal shrinkage. After that, the mold is removed to reveal a finished, machinable product.
Above is a simple explanation and description of how the gold induction furnace melts the metal.

Hfinduction Heater Gold Melting Furnace Induction

1.  The melting induction furnace is capable of melting various metals such as gold, platinum, silver, iron, copper, stainless steel and the like.


2. By using an electromagnetic induction heating system, the induction furnace is able to adjust the heating power. Our metal induction has an electromagnetic automatic mixing function, without stirring by the stirring rod to ensure the uniform melting color.
3. Induction Melting furnace has a rapid melting speed. For example, melting 2KG gold within 1-5 minutes, melting 1KG platinum within 1-2 minutes.


4. An optional choose to configure the temperature controller, which will display and control the metal temperature so that to make the smelting product with higher quality. By using the thermocouple temperature sensor or infrared temperature sensor to measure the temperature. It is mainly used to detect the bottom temperature of the graphite crucible. The temperature range is 400-1200 degrees Celsius.

The temperature controller is used to display and control the metal temperature. It can automatically stop heating or keep warming when reaches the target record.


5. This gold melting induction furnace is easy to use and operate. It can be available for graphite crucible or ceramic crucible. Crucible or tank with different size or specifications can be customized accordingly.

Able to Melt Non-Ferrous & Ferrous Metals

Generally, working with smelting crucibles, like graphite crucible, is available for precious metal melting, such as melting platinum, gold, silver, etc.
By heating up the graphite crucible, induction furnace is also suitable for melting semiconductor material.
For metallurgical industry, it’s a good choice to deploy induction melting furnace to smelt some high quality and expensive materialFor instant, specialized steel, iron and copper or metal alloy such as aluminum alloy, zinc alloy and copper alloy, etc.

What is induction heating?


The heating method known as induction heating occurs when we place an electrically conductive material in a varying magnetic field. So induction heating is a rapid form of heating. Its current is induced directly into the heated par. Also, induction heating is a non-contact form of heating.


How to melt metal?


Induction heating machine can also use for melting platinum, silver crucible, etc. It’s simple and easy, together with working with smelting crucible, especially the graphite crucible and quartz crucible.

Can you braze glass or ceramics with induction?


If you work with glass or ceramics, a compact vacuum furnace is a great solution for brazing. You’ll get quick, clean heat with very precise temperature control.


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 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. Hence place a work piece within the coil and enters the magnetic field, then it induces eddy currents within the workpiece. Furtherly it’s generating precise and localized heat without any physical contact between the induction coil and the workpiece.



Will induction heating increase my utility bills?


Not likely. Induction heating is a very effective, efficient means of heating. Most of our customers who are switching to induction for the first time see their utility bills go down.


What are the typical utility requirements for induction?


Of course, it depends on the system, but a typical system requires 380, 3-phase VAC at 50 Hz and 30 Amps. Also, figure on 80 PSI compressed air and 40 PSI water at 4 gallons per minute for cooling.


Is this joint suitable for induction brazing?


Our team of metallurgical and mechanical engineers will be glad to have a look at your parts and process and give you our best advice – no obligation!


How can my process benefit from induction heating?


It can benefit your process in a number of ways. Induction heating is highly repetitive once making the initial adjustments to the power supply. Following this phase, it will heat part after part with identical results so long as introduces the parts to the coil similarly to 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 an application such as brazing and soldering. The ability of induction heating to heat all parts identically lends itself to the automation of the process. Induction heating can also heat the part in a highly localized fashion. It can be extremely beneficial when it is desirable or necessary to limit the heat to only a certain region of the part.


What are some of the other advantages of using Induction Heating?


Fast Cycle Times – With induction heating technology, it produces heat instantly and directly within the heated part.  Thus it supplies heat as quickly as a material will permit it, eliminating typical soak times associated with radiation or convection heat technologies.


Accurate Heat Zones – It can also isolate or pinpoint a heat-zone and small or large without affecting surrounding areas.  So the result is minimal distortion in part being heated and yielding higher quality production. Furthermore, additional infrared temperature control devices can also be added for further control of a process.


Consistent and Repeatable – Due to the development of Solid-State power supplies, the heating pattern produced by a given induction coil will be consistent from day to day, month to month.  The process will remain repeatable, rather than traditional flame heating or resistance heating having constantly changing characteristics.


Space Requirements and Efficiency – Due to the smaller space requirements for induction heating, this technology lends itself to bench-top/work cell environments and in-line semi or fully automated processes.  In addition Induction, Heating technology is energy efficient. And power consumption to create the output power is minimal and in idle. Besides, stand-by conditions power consumption is greatly reduced since the power is only on when utilizes the system for the intended process.


Environmentally Friendly – Induction heating is an extremely clean heat.  Also, it does not produce harmful emissions or loud noise.  Furthermore, it does not heat the environment or area outside the work coil, since it only generates the heat in the heated workpiece.  Thus induction heating assists in creating more favorable working conditions.


How hot does the induction coil get?


The induction coil is cool to the touch and the heat that builds up in the coil is constantly cooled with circulating water.

Can you use induction heating to braze steel parts in a nitrogen atmosphere?


Yes, you can. But the nitrogen has to be clean and have a low dew point.


Can diamond bits be brazed with induction heating?


Sure, in fact, induction heating is preferable for diamonds bits because it works so quickly. The longer the diamond remains at heating temperature, the faster it degrades. So we recommend atmospheric brazing in a vacuum atmosphere for the best results.


When is it better to use the indirect heat of an induction furnace instead of direct induction heat?


Yeah, we get that question a lot. It depends on the geometry of your part and how you want to heat it. If you have a part with simple geometry and your process calls for heating a specific area of the part. We suggest that direct induction heating will generally be preferable. However, if you need to heat the entire part, or if the part has a complex shape. Then you’ll achieve better results with an induction heating vacuum furnace.
