感应加热技术具有升温快,功率高,易于控制,工艺质量可靠,氧化脱碳少,环境和作业条件良好等优点,因此其应用已涉及黑色或有色金属的熔炼、加热、淬火及回火等多种处理、钎焊、直缝管材高速焊接、电真空器件排气加热等领域。 对需要进行加热的工件而言,其电阻率和磁导率等物性常数与温度是密切相关的,随着加热温度的变化,感应加热电源输出回路中的感抗将发生变化,从而导致输出回路谐振工作点的变化,因此,为了提高加热效率和加热速度,感应加热电源需要 Induction heating technology with fast heating, high power, easy to control, process quality, oxidation and decarburization less, good environmental and operating conditions, etc., its application has been involved in black or non-ferrous metals smelting, heating, quenching and tempering, etc. Kinds of treatment, brazing, straight seam pipe high-speed welding, electrical vacuum devices exhaust heating and other fields. For the workpiece to be heated, its resistivity and permeability and other physical constants and temperature are closely related, with the heating temperature changes, inductive heating power output circuit inductance will change, resulting in the output circuit Resonant work point changes, therefore, in order to improve the heating efficiency and heating rate, induction heating power needs
