Induction Melting Furnace vs Induction Heating Furnace: A Comprehensive Comparison


Kehua is a leading manufacturer of medium frequency induction melting and heating equipment, offering a wide range of innovative and reliable solutions to various industries. As an industry leader, Kehua has a deep understanding of the differences between induction melting furnaces and induction heating furnaces. In this article, we will explore the distinctions between these two types of furnaces and how they are used in different industrial applications.


What is an Induction Melting Furnace?


An induction melting furnace is a type of induction heating equipment designed specifically for melting and casting metals, alloys, and other materials. It utilizes the principle of electromagnetic induction to generate heat and melt the metal. The furnace works by circulating a high-frequency alternating current (AC) through a water-cooled copper coil, creating a powerful magnetic field.


When metal is placed inside the coil, the magnetic field induces eddy currents within the metal, generating heat and causing it to melt. The molten metal can then be poured into molds to create various shapes and forms. Induction melting furnaces are widely used in foundries, metalworking shops, and other manufacturing industries for melting and casting steel, copper, aluminum, and other metals.

Kehua offers a variety of induction melting furnaces, including induction vacuum melting furnaces and GTR series diathermy furnaces, to cater to the diverse needs of its customers.


Induction Melting Furnace Features:


Fast and efficient: Induction melting furnaces can melt metal much faster than traditional furnaces, making them ideal for large-scale production.


Clean and eco-friendly: Induction melting furnaces do not emit harmful fumes, making them environmentally friendly.


Precise temperature control: The temperature of the molten metal can be easily controlled and maintained, ensuring a consistent quality of the final product.


Versatile: Induction melting furnaces can melt a wide range of metals, making them suitable for various industrial applications.


What is an Induction Heating Furnace?


An induction heating furnace is a type of industrial electric furnace that uses the same principle of electromagnetic induction as induction melting furnaces, but for heating purposes. It employs a high-frequency alternating current to heat metals, alloys, and other materials to a specific temperature.


An induction heating furnace comprises an insulated coil, typically made of copper, which generates an electromagnetic field when electricity is passed through it. The material to be heated is placed inside the coil, and the magnetic field induces eddy currents within it, causing it to heat up. Induction heating furnaces are widely used in the metalworking industry for processes such as brazing, forging, heat treatment, and welding.


Kehua offers a range of induction heating furnaces with advanced features such as IGBT medium frequency power supply and KGPS high voltage SCR induction power supply for precise and efficient heating.

Induction Heating Furnace Features:


Energy-efficient: Induction heating furnaces consume less energy compared to traditional heating methods, making them cost-efficient.


Precise heating: The temperature of the material can be precisely controlled, making it suitable for applications that require specific heating temperatures.


Faster heating: Induction heating furnaces heat up materials faster than other conventional methods, resulting in improved efficiency and productivity.


Clean and safe: Induction heating furnaces do not involve burning or combustion, making them safe and clean for workers and the environment.


Differences between Induction Melting Furnace and Induction Heating Furnace


While both induction melting furnaces and induction heating furnaces use similar principles of electromagnetic induction, they differ significantly in terms of their features, uses, and applications. Some of the key differences between these two types of furnaces are:


● Purpose: The main difference between an induction melting furnace and an induction heating furnace is their purpose. An induction melting furnace is designed specifically for melting and casting metals, whereas an induction heating furnace is used for heating materials to a specific temperature.


● Output power: Induction melting furnaces generally have a higher output power than induction heating furnaces as they need to generate more heat to melt metals.


● Temperature control: Induction melting furnaces require precise temperature control to ensure the molten metal has the desired quality. On the other hand, induction heating furnaces need to be able to achieve specific temperatures for various heating processes.


● Material compatibility: Induction melting furnaces are suitable for a wider range of materials, including metals, alloys, and other materials. Induction heating furnaces are typically used for heating only conductive metals and alloys.


● Size and shape: Induction melting furnaces are generally bigger and bulkier than induction heating furnaces due to the need for a crucible to hold the molten metal. Induction heating furnaces, on the other hand, can take different forms depending on the application, such as a cylindrical, rectangular, or round shape.

Which One Is Right for Your Business?


Choosing the right furnace for your business depends on the specific needs of your industry. If you need to melt and cast metals, an induction melting furnace is the ideal choice. On the other hand, if you require precise heating for processes such as brazing, forging, or heat treatment, an induction heating furnace would be more suitable.


Kehua offers a wide range of high-quality, efficient, and reliable induction melting and heating furnaces to meet the diverse needs of its customers. With over 20 years of experience in the industry, Kehua is a trusted and reputable manufacturer, known for its innovative solutions and exceptional customer service.
