Types of electric metal melting furnaces

An electric metal melting furnace is a piece of equipment used to melt metals using electricity as the primary source of energy. They are designed to consume low energy and have high safety standards. There are various types of electric metal melting furnaces.

• Induction melting furnaces:

  An induction metal melting furnace works by electromagnetic induction. It consists of a coil that creates a magnetic field that induces heat within the metal. The furnaces are designed to be eco-friendly, generate low noise, and have low energy consumption. They have high-efficiency rates and mostly used to melt stainless steel, brass, copper alloys, and aluminum. The melting rates depend on the size and power output of the induction coil.

• Crucible furnaces:

  A crucible furnace consists of a container where metal charges are placed, and a heating element that heats the container to melt the metal. The containers are made from ceramic or steel. The types of electric furnace crucibles include electric resistance crucible furnaces or electric induction crucible furnaces. The furnaces are commonly used to melt small quantities of brass, copper, aluminum, gold, silver, and platinum. They have an average melting time of 20 to 90 minutes depending on the size of the furnace and metal.

• Arc furnaces:

  An electric arc furnace produces heat to melt metal through electrical arcs between electrodes and the metal. The 3-point arc electrode design allows easy electrode replacement and improves power distribution. The induction electric arc melting furnace is similar to the electric induction method, and the electrodes are placed on the sides of the furnace. This allows better heating and control of the melting process. Electric arcs have high voltage and use alternating currents. Electric arc furnaces are commonly used in steelmaking and the recycling of scrap metals.

Specification & Maintenance

Choosing the proper electric melting furnace is about more than just power and capacity. It's about understanding the material it's built to serve, along with the intricacies of its temp control and safety systems. Every detail, from its water-cooled induction coils to the durability of the refractories lining it, matters in crafting a machine that melts metals effectively and reliably.

• Power Source: Electric melting furnaces rely on a consistent power supply, often 3-phase electricity, to operate efficiently.
• Installation:Once the power source is ensured, proper installation is vital for safety and functionality. Electric furnaces need to be linked with grounded electrical systems to prevent shocks. Adequate exhaust systems must divert harmful gas away from workspaces.
• Induction Coils: For induction electric melting furnaces, the water-cooled induction coils are vital components to be checked. As the name suggests, these are cooled with water, swirling around them in tubes, to avoid overheating during metal melting. Ensuring cooling water is always circulating prevents induction coil damage from excessive heat.
• Temperature Controls:Modern electric furnaces have sophisticated computerized programmable temperature control systems that give precise command of the melting process. Regularly check and correctly set these temperature control units. Electric furnaces use electricity as their heating source. Routinely check its source and connections. Cords and plugs must be intact, without wear or damage, providing a direct, safe power flow.
