Trend of induction heating equipment and technology

Induction heating machine originates from the electromagnetic induction phenomenon discovered by Faraday, that is, alternating current produces induction current in conductors, which leads to conductor heating. In 1890, Swedish technicians invented the first induction melting furnace, slotted cored furnace, and the American invented closed slot cored furnace in 1916. Since then, induction heating technology has gradually entered the practical stage. The rapid development of power electronic devices and technology in the 20th century. The development of induction heating technology has been greatly promoted.

In 1957, the United States developed a thyristor as a milestone in power electronics, marking the beginning of modern electronic technology and the revolution of induction heating technology. In 1966, Switzerland and West Germany first developed induction heating equipment using thyristors, Since then, the induction heating technology has started the high-speed development

1. Characteristics of induction heating equipment: the induction heating equipment has the characteristics of quick, clean, energy-saving, easy to realize automation and on-line production, high production efficiency and the like, is an internal heat source, belongs to a non-contact heating mode, can provide high power density, The invention has the advantages of high and flexible selectivity on the heating surface and the depth, can work in various carrier gas (air, protective gas and vacuum), has very low loss, does not generate any physical pollution, is in accordance with the policy of environmental protection and sustainable development, and is one of the green environment-friendly heating processes. The induction heating equipment and the controllable atmosphere heat treatment, the vacuum heat treatment and the non-oxidation technology have become the mainstream of the heat treatment technology.

2. Its main application is as follows: (1) heat treatment of non-ferrous metal, heat treatment of metal materials, heat treatment of forging, extrusion, rolling and the like, and weld of welded pipe production. (2) Mechanical manufacturing, quenching of various mechanical parts, and heat treatment such as tempering, annealing and normalizing after quenching; heat penetration before pressure processing. (3) The closure of light industry, can and other packaging, such as the sealing and packaging of the well-known Tetra Pak. (4) heating the vacuum degassing of the electron and the electron tube. (5) Special applications, such as plasma, surfacing, etc.
