Description

Technical Field

[0001] The invention relates to the technical field of medium frequency heating furnaces, and in particular to a noise reduction device for a front axle forging feeding section of a medium frequency heating furnace. Background Art

[0002] A medium frequency heating furnace is a power supply device that converts 50HZ industrial frequency alternating current into medium frequency (300HZ to 1000HZ). It 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. Eddy currents also have some properties of medium frequency currents, that is, the free electrons of the metal itself flow in a metal body with resistance to generate heat. When loading the front axle forgings into the medium frequency heating furnace, a noise reduction device is required to soundproof the sound generated when the forgings are loaded.

[0003] After searching the Chinese patent "A wear-resistant heating furnace wall", the announcement number is "CN217504346U". This patent sets a wear-resistant layer and the wear-resistant layer is made of plastic refractory castable. The plastic refractory castable has good high-temperature strength, thermal shock stability and spalling resistance, which can effectively reduce the hidden danger of furnace wall wear caused by the bent billet scratching the furnace wall. By setting the sound insulation layer and the sound-absorbing layer, the noise inside the furnace body can be isolated to avoid affecting the physical and mental health of the staff. By setting the first insulation layer, the second insulation layer and the heat insulation layer, the furnace wall has good thermal insulation and heat insulation functions. By setting the connecting layer, it can have good shock absorption. The comprehensive performance of the furnace wall is better and the overall service life is longer. However, the device is prone to generate noise when loading the front axle forgings, and it is not convenient to reduce and silence the noise generated when loading the forgings, which will affect the comfort of the working environment and work efficiency.
