Technical Field

Background

Nickel; a metallic element which is nearly silvery white, hard and ductile and has ferromagnetism, and which is highly polished and resistant to corrosion. After dissolving in nitric acid, it is green. Mainly for alloys (such as nickel steel and nickel silver) and as catalysts (such as raney nickel, especially as hydrogenation catalysts).

Electromagnetic induction heating, or induction heating for short, is one method of heating conductive materials such as metallic materials. The induction heating method is mainly used for metal hot working, heat treatment, welding and melting, the induction heating is to generate current inside a heated material by using an electromagnetic induction method, and the heating purpose is achieved by depending on the energy of eddy current. The basic components of an induction heating system include an induction coil, an ac power source, and a workpiece. The coil can be made into different shapes according to different heating objects. The coil is connected to a power supply which supplies an alternating current to the coil, the alternating current flowing through the coil generating an alternating magnetic field through the workpiece, which causes the workpiece to generate eddy currents for heating.

Induction heating is a relatively new process that finds application primarily because of its unique properties. When a rapidly changing current is passed through a metal workpiece, a skin effect is produced which concentrates the current on the surface of the workpiece, creating a highly selective heat source on the metal surface. Faraday found this advantage of the skin effect and found the phenomenon of electromagnetic induction, which is of interest. He is also the founder of induction heating. Induction heating does not require an external heat source, but rather utilizes the heated workpiece itself as a heat source, nor does this method require the workpiece to be in contact with an energy source, i.e., an induction coil. Other properties include the possibility of selecting different heating depths depending on frequency, precise local heating according to coil coupling design, and high power density or power density.
