Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically a fully automatic steel heating furnace. Background Technology

[0002] A forging heating furnace is a power supply device that converts 50Hz AC power into medium-frequency (300Hz and above to 20kHz) power. It rectifies the three-phase AC power into DC power, then converts the DC power into adjustable medium-frequency current via a frequency converter. This DC current is supplied to the capacitor and induction coil, generating a high-density magnetic field in the induction coil. This magnetic field cuts through the metal material within the induction coil, creating large eddy currents within the metal. These eddy currents also exhibit some properties of medium-frequency currents, namely, the generation of heat as free electrons flow through the resistive metal.

[0003] In the existing technology, due to the lack of a support mechanism during the feeding process, the workpiece undergoes flexible deformation, and the workpiece rubs against the induction coil, causing wear on both the workpiece and the coil. In severe cases, this can cause a short circuit in the coil, and the workpiece is not in the axial position of the coil, which will reduce the heating effect of the workpiece.
