Description

Technical Field

[0001] The utility model relates to the technical field of forging heating furnaces, in particular to a forging heating furnace which is convenient for temperature control. Background Art

[0002] A forging heating furnace is a power supply device that converts 50HZ industrial frequency alternating current into medium frequency (300HZ or above to 20KHZ). It converts three-phase industrial frequency alternating current into direct current after rectification, and then converts the direct current into adjustable medium frequency current through a frequency conversion device, which supplies the medium frequency alternating current flowing through the capacitor and induction coil, generates high-density magnetic lines in the induction coil, cuts the metal material contained in the induction coil, and generates large eddy currents in the metal material.

[0003] When the forging heating furnace in the prior art is temperature controlled, there is a good control scheme for the temperature rise and combustion inside the furnace body, while the cooling inside the forging heating furnace usually relies on the fan to discharge the air in the furnace to achieve temperature-controlled cooling. However, the cooling pipe structure of the existing forging heating furnace is relatively simple, and the chamber structure for drawing out the air in the forging heating furnace is small, which results in a longer time for the forging heating furnace to be temperature controlled and cooled, and cannot meet the temperature control and cooling requirements of the forging heating furnace. For this reason, we propose a forging heating furnace that is easy to temperature control. Utility Model Content

[0004] The main purpose of the utility model is to provide a forging heating furnace which is easy to control in temperature.
