7 Considerations to Make When Buying Industrial Induction Furnaces

An induction melting furnace is an electric metal melting furnace. These furnaces use alternating current (AC), which flows through a primary coil and generates an induced current. The generated current flows through the secondary induction heating coil and generates heat. The generated heat heats furnace parts that melt scrap metal at high temperatures.

What are the benefits of induction melting furnaces?

Why buy an induction melting furnace in the first place? For starters, the induction furnace melting process is energy-efficient, controllable, and clean. It’s thus a preferable method of processing metals. An induction melting furnace heats metals by use of an induction heating coil and the process produces minimal dust and pollutants. The furnaces also vary in size. As such, you can start operations with a medium-sized furnace and later on, you can move on to a big one as your operations expand. Here are the seven essential considerations that you should make when buying an induction furnace.

1. Eco-Friendliness

Unlike furnaces that use coal, an induction melting furnace doesn’t generate lots of waste (which is hard to dispose of and hazardous to the environment). These furnaces generate minimal dust and pollutants, which diffuse into the atmosphere. Induction furnaces are thus ideal for you if you’re concerned about the environment.

2. Reduced Oxidation

The core type induction melting furnace will give you low levels of oxidation in the melting process. A lower oxidation rate in the melting process implies that you will get a high rate of yield, which leads to better production rates. It is thus essential to always check the oxidation rates when purchasing your industrial furnace.

3. Customizable Sizes

Industrial induction furnaces have a custom-built induction heating coil that suits different levels of operation. These furnaces come in different sizes and the smallest of them often need small material refractions. If your operations aren’t large, it’s advisable to buy a small induction furnace. But you should determine your ultimate choice based on the size of your business and the anticipated scale of production.

4. Noise Minimization

Noise in a production facility can be bothersome. Environment laws and regulations may also compel you to lower noise levels in your foundry. It’s thus important to check the induction furnace noise levels before buying an induction furnace. Fortunately, Advances in technology have allowed induction furnace manufacturers to build furnaces with minimal noise.

5. Increased Production Rates

The induction heating coil heats the induction furnace in a rapid manner that permits the fast generation of heat. The quick heating allows the fast melting of all metals. Isn’t this quality an ideal prompt to buy an induction furnace to serve as a way to increase your production rates?

6. Durability

How strong and big is the shell of the induction furnace? The strength and durability of the induction furnace determine the quality of the furnace that you’ll buy. You should ensure that the furnace you intend to buy is of good quality and it should be easy to maintain and install.

7. Controllability

A perfect choice of an induction furnace should be easy to set up, control, and maintain. One of the main controlled features is the emission of pollutants, dust, and smoke. An ideal furnace should have a control mechanism for controlling emissions. The furnace should also have a power supply control for the induction heating coil. The control will ensure that the furnace works in a steady and efficient manner even when running for many hours.

When it comes to purchasing an induction heater, whether for industrial applications or personal use, there are several crucial features you should consider. As a supplier of induction heaters, I've seen firsthand the diverse needs of our customers and understand the importance of making an informed decision. In this blog post, I'll walk you through the key features to look for when buying an induction heater.

Power and Heating Capacity

One of the most important factors to consider is the power and heating capacity of the induction heater. The power of an induction heater is typically measured in kilowatts (kW). A higher power rating generally means faster heating times and the ability to heat larger or more massive objects.

For small-scale applications such as heating small bearings or bolts, a lower power induction heater in the range of 1 - 5 kW may be sufficient. These heaters are compact, energy - efficient, and suitable for workshops or home use. On the other hand, industrial applications that involve heating large metal components, such as in the manufacturing of heavy machinery or automotive parts, often require high - power induction heaters, sometimes exceeding 50 kW.

Our Large Induction Heater WTR HOR Series offers a wide range of power options to meet different industrial needs. With its high - power output, it can quickly heat large metal parts, improving production efficiency.

Frequency

The frequency of an induction heater is another critical feature. Frequency is measured in hertz (Hz) and affects how deeply the heat penetrates the metal object. Low - frequency induction heaters (below 10 kHz) are ideal for heating large, thick metal parts. The lower frequency allows the heat to penetrate deeper into the material, ensuring uniform heating throughout the part.

High - frequency induction heaters (above 100 kHz) are better suited for heating small, thin - walled parts or for surface hardening applications. The high frequency concentrates the heat on the surface of the metal, minimizing heat loss and reducing the risk of overheating the interior of the part.

When choosing an induction heater, you need to match the frequency to the size and type of the objects you plan to heat. Our technical team can provide expert advice on selecting the appropriate frequency for your specific application.

Temperature Control

Precise temperature control is essential for many induction heating applications. Whether you're annealing, brazing, or tempering metal, maintaining the correct temperature is crucial to achieving the desired results. Look for an induction heater that offers accurate temperature control.

Some advanced induction heaters come with digital temperature controllers that allow you to set and monitor the heating temperature. These controllers can provide real - time feedback, ensuring that the metal reaches and maintains the target temperature throughout the heating process.

In addition, over - temperature protection is an important safety feature. It prevents the heater from overheating, which can damage the equipment and pose a safety hazard. Our induction heaters are equipped with reliable temperature control systems and over - temperature protection mechanisms to ensure safe and efficient operation.

Safety Features

Safety should always be a top priority when using any electrical equipment, and induction heaters are no exception. There are several safety features you should look for in an induction heater.

Ground fault circuit interrupters (GFCIs) are an important safety feature that can protect against electrical shocks. They automatically shut off the power if a ground fault is detected, reducing the risk of injury.

Over - current protection is another essential feature. It prevents the heater from drawing excessive current, which can damage the electrical components and cause a fire.

In addition, the induction heater should have proper insulation and shielding to prevent electromagnetic interference (EMI) and protect the user from exposure to harmful electromagnetic fields.

Ease of Use and Portability

The ease of use of an induction heater can significantly affect your productivity. Look for a heater with a user - friendly interface, such as a digital display and simple control buttons. This makes it easy to set the heating parameters and monitor the heating process.
