Description

Technical Field

[0001] This utility model relates to the field of high-frequency melting technology for alloy steel sleeves, and in particular to a high-frequency melting device for alloy steel spacers. Background Technology

[0002] High-frequency furnace melting refers to the method of heating and melting glass using a high-frequency electric furnace. Its advantages include rapid heating and less pollution, making it suitable for melting special glasses that are prone to crystallization but have minimal impact on crucible erosion. High-frequency melting is the main melting method for manufacturing multi-component glasses for optical fiber materials.

[0003] The principle of high-frequency melting of alloy steel sleeves is based on the principle of electromagnetic induction. Specifically, when a high-frequency current passes through an induction coil, it generates an alternating magnetic field. When the metal is placed in this magnetic field, eddy currents are generated inside the metal. Due to the resistance of the metal, the eddy currents generate Joule heat, which causes the metal to heat up and melt rapidly. This melting method has the advantages of high efficiency, energy saving and environmental protection.
