Example Embodiment

[0047] Example 1:

[0048] Reference figure 2 As shown, this embodiment provides an intermediate frequency induction heating furnace body, which includes a furnace shell 4 and a furnace lining 1. The furnace lining 1 is provided with a material passage 11 through which the blank passes. During forging, the blank is along the material passage 11 Axial travel.

[0049] The furnace lining 1 is provided with an induction coil 2 extending in the axial direction of the material channel 11 and spirally wound on the outside of the material channel 11; wherein the induction coil 2 is wound by a copper tube.

[0050] The side wall of the furnace lining 1 is provided with a plurality of temperature measuring holes 12 distributed along the axial direction of the furnace lining 1, wherein the temperature measuring holes 12 are arranged radially along the furnace lining 1 and penetrate the side wall of the furnace lining 1 to communicate with the forehearth 11, and the measuring holes 12 The war...

Example Embodiment

[0061] Example 2

[0062] Such as Figure 2-Figure 4 As shown, this embodiment provides a method for manufacturing the intermediate frequency induction heating furnace described in Embodiment 1, which specifically includes the following steps:

[0063] S100. Winding induction coil 2: Put the copper tube on the copper tube winding machine, and use the copper tube winding machine to wind the copper tube into a spiral to form a section of induction coil 2; repeat this step to wind several sections according to actual needs Induction coil 2.

[0064] Finally, all the induction coils 2 are connected in series or in parallel, and it should be noted that the induction coils 2 are coaxially arranged.

[0065] In this step, according to the position of the temperature measuring hole 12 to be opened, the gap between the induction coil 2 corresponding to the two-turn coil located on both sides of the temperature measuring hole 12 is appropriately increased, so as to ensure that the two-turn coi...

Example Embodiment

[0085] Example 3

[0086] Combine figure 1 As shown, this embodiment provides a temperature control method applied to the electric furnace body 01 in Embodiment 1, which specifically includes the following steps:

[0087] The first step is to install a thermometer 9 coaxially arranged with the temperature measuring hole 12 outside each of the temperature measuring holes 12 (the thermometer at the temperature measuring hole is not shown), wherein the thermometer 9 is specifically An infrared thermometer can be used.

[0088] All the thermometers 9 are connected to the control device, and the control device is used to control and adjust the input power of the induction coil 2 according to the temperature signal fed back by the thermometer 9. The control device can be a PLC or a finished instrument, of course, it can also be another control device, which is not specifically limited here; the following uses a PLC as the control device as an example for description.

Abstract

The invention relates to the technical field of medium-frequency induction heating furnaces, in particular to a medium-frequency induction heating furnace body, a furnace body manufacturing method anda temperature control method. The medium-frequency induction heating furnace body comprises a furnace lining, a material channel allowing a blank to pass through is formed in the middle of the furnace lining, and an induction coil which extends in axial direction of the material channel and is spirally wound on outer side of the material channel is arranged in the furnace lining; and a pluralityof temperature measuring holes are formed in the side wall of the furnace lining in the axial direction of the furnace lining at intervals, the temperature measuring holes are formed in the radial direction of the furnace lining and penetrate through the side wall of the furnace lining, and the temperature measuring holes are located at the intervals between every two adjacent turns of coils of the induction coil. The invention further provides a manufacturing method of the medium-frequency induction heating furnace body and a temperature control method of the medium-frequency induction heating furnace. According to the furnace body, the temperature measuring holes are formed in the side wall of the furnace body for temperature measurement instead of adopting the temperature measurement mode at a discharge port so that the temperature measurement accuracy can be improved.

Description
