According to the embodiment of the rotary induction heating device, cooperative work of raw material heating and load transmission is realized.

Description

technical field [0001] The invention relates to a rotating induction heating device. Background technique [0002] With the development of material processing technology, there are special requirements for material heating technology and equipment in some occasions. For example, the feeding process of some additive forming processes requires local rapid heating of the conveyed metal raw materials. It is necessary to transmit force or torque loads along the direction of the feed axis at the same time. [0003] Especially when heating high-melting-point metal materials such as steel, titanium, and nickel alloys, the heating temperature needs to reach above 1000°C, the heating rate is ≥30°C / s, and it is required to transmit large axial torque and axial force. Traditional high-temperature metal Structural materials cannot maintain strength at high temperatures above 1000°C, and ceramic materials cannot meet high torque, alternating dynamic loads, and high thermal stress environ...
