The difference between a casting electric furnace and a cupola furnace

The induction melting furnace used in casting is a medium-frequency induction furnace that is adapted from equipment originally employed in the traditional casting industry. Casting is a manufacturing process in which metal is melted into a liquid state meeting specific requirements and then poured into molds. After cooling and solidification, followed by cleaning and finishing operations, the castings attain the desired shape, dimensions, and properties.

Advantages of Dust Collectors for Foundry Electric Furnaces

A casting electric furnace is a heating furnace that converts electrical energy within the furnace into heat to heat workpieces. Compared with fuel-fired furnaces, casting electric furnaces offer the following advantages: The furnace atmosphere is easy to control—even to the point of being evacuated to a vacuum; materials heat up quickly, reach high temperatures, and the temperature is easy to regulate; the production process is relatively easy to mechanize and automate; working conditions are improved in terms of occupational health and safety; thermal efficiency is high; product quality is excellent; and the furnace is more environmentally friendly—making it an excellent solution for addressing increasingly serious environmental issues.

Casting Electric Furnace Operating Procedure

The complete set of induction furnace production equipment mainly includes a medium-frequency power supply cabinet, compensation and capacitors, two furnace bodies, water-cooled cables, and a gearbox. Each furnace body consists of four main components: the furnace shell, the induction coil, the furnace lining, and the tilting reduction furnace. The furnace shell is made of non-magnetic material, and the induction coil is a rectangular hollow tubular helix through which cooling water flows during melting.

Detailed Introduction to Casting Electric Furnaces

The currently popular medium-frequency induction melting furnace used in casting electric furnaces can heat and melt scrap metal materials such as steel, aluminum, copper, gold, and silver. Alloying elements can be added during the process, and through procedures like slag removal, the material is transformed into qualified molten metal. After pouring, castings are formed. This type of furnace features quick start-up, high heating efficiency, electromagnetic stirring, immediate usability, low energy consumption, and environmental friendliness.

Advantages of induction furnaces for casting

The product quality is excellent. The induction furnace for casting requires no auxiliary combustion air, produces no flue gas, and keeps the furnace chamber clean. The furnace temperature can be precisely controlled, and the prescribed heating system can be maintained with strict accuracy, ensuring a uniform temperature distribution throughout the furnace chamber. Typically, the baking temperature difference is kept within a range of ±5-10℃. Some induction furnaces for casting have even narrower temperature fluctuation ranges, making them well-suited to meet the requirements of various heating systems. As a result, products baked in these induction furnaces for casting exhibit high quality and a high pass rate.

A mid-frequency induction furnace manufacturer briefly explains the working principle of a mid-frequency induction furnace.

The manufacturer of medium-frequency induction furnaces explains that in a medium-frequency induction furnace, medium-frequency current is transmitted to the load via an induction coil, which is an integral part of the inverter. The induction coil and the charge material exhibit a very low power factor, necessitating the use of tuning capacitors to supply non-functional energy to the induction-heating load. In practice, capacitors are used either in series or in parallel with the induction coil.

What are the advantages of medium-frequency induction furnaces, as introduced by manufacturers?

A medium-frequency induction furnace is a power supply device that converts 50 Hz industrial frequency AC into medium frequency (above 300 Hz up to 10,000 Hz). It consists of a frequency conversion unit, a furnace body, and a front-end control system. Medium-frequency induction furnace manufacturers point out that these furnaces can serve as tools for smelting technology and metal processing; however, if the metallic materials contain impurities, the quality of the resulting products will be compromised, seriously affecting both social welfare and public health.
