Product Description

The compact flux electromagnetic electric melting furnace, primarily used for melting tin and tin-lead alloys. The whole equipment is composed of a melting furnace body and an electrical control system.

The furnace outer shell adopts a welded steel plate structure, and the inner melting pot is made of 304 stainless steel. A push-pull handle is installed on the side of the furnace body, and universal casters are mounted at the bottom, allowing the furnace to be moved freely for easy operation.

This equipment adopts magnetic field induced current (eddy current) heating principle. High-frequency current is generated by the built-in electronic circuit board components: the rectifier circuit converts 50Hz alternating mains current into DC voltage, which is then converted into 20–40kHz high-frequency alternating current through the control circuit. The spiral magnetic induction coil generates a high-frequency alternating magnetic field. When magnetic flux passes through the stainless steel melting pot, alternating eddy currents are produced inside the pot. The eddy currents drive the metal molecules of the pot to move irregularly at high speed; molecular collision and friction generate heat to heat the pot body directly, converting electric energy into thermal energy with a maximum thermal efficiency of 93%, realizing efficient heating.

The matched electrical control system can automatically adjust the furnace temperature and trigger automatic constant temperature preservation once the preset temperature is reached.

Note: The smoke exhaust system shall be designed and installed by users on-site according to actual working conditions.

Product Advantages

High Efficiency & Energy Saving

Traditional resistance wire furnaces work by heating resistance wires to red heat first, then transferring heat to the tin pot via air convection, and finally conducting heat to molten metal. Multiple heat transfer links lead to heavy heat loss, with thermal efficiency only 40%–65% and slow temperature rise. This electric melting furnace relies on eddy current to directly heat the melting pot, keeping thermal efficiency above 80%. To melt 200kg tin liquid, traditional resistance furnaces take about 2 hours, while this unit only needs 30–40 minutes, greatly saving electricity consumption and production time.

Environmentally Friendly

No combustion, no waste gas emissions, no oxygen consumption, low operation noise and zero secondary pollution to the workshop.

Safe & Reliable Operation

No open flame during operation. Only the bottom of the melting pot generates heat, while the furnace outer body stays cool. It will not raise ambient temperature sharply and effectively eliminates scald hazards to operators.

Precise Temperature Control

Heating power and furnace temperature can be flexibly adjusted according to production requirements. Users can set arbitrary target temperatures through the electric control system. The instant heating feature brings rapid response, making temperature control more sensitive and accurate than traditional furnaces.

Long Service Life

Traditional furnaces have easily aging resistance wires that need regular replacement. The induction heating structure of this electric melting furnace has no vulnerable heating components, delivering a much longer service life and lower maintenance costs.
