It includes an outer cover 202, and a base 203 positioned below the inner cover 201 and the outer cover 202 to support the coil (C).

Heat is generated in the space S by a burner or the like, and heat is transferred to the inside of the inner cover 201 to heat the atmosphere gas. A fan is installed in the base 203, and the base 203 implements convection by circulating the heated atmospheric gas inside the inner cover 201. For this reason, the coils C loaded inside the inner cover 201 are annealed.

In addition, the guide posts 204 are installed with the batch annealing path 200 interposed therebetween, and fix the inner guide 211 extending from the inner cover 201 and the outer guide 221 extending from the outer cover 202. Let's do it. For this reason, the batch annealing furnace 200 is maintained in a fixed state by the guide post 204.

On the other hand, in the batch annealing furnace, the base may be deformed to support the loaded coils. In addition, since the heated atmospheric gas is high temperature, when the base circulates the atmospheric gas to anneal the coils, the base is thermally expanded by the atmospheric gas and is damaged or broken. As a result, the loaded coils may be inclined and the batch annealing furnace itself may be damaged or broken. However, even the deformation of the base is not detected.

The present invention is to provide a base of the batch annealing furnace that can detect the deformation according to the load of the atmosphere gas and coil to prevent damage and breakage.

In addition, the present invention is to provide a base of the batch annealing furnace that can implement a stable annealing treatment of the coil, and can extend the life of the batch annealing furnace.

The present invention is a base plate of the batch annealing furnace is installed on the lower surface of the batch annealing furnace, the coil located inside the batch annealing furnace, the load plate portion (the inner diameter of the coil in the load plate portion) Openings corresponding thereto are formed); A flow portion positioned below the load plate portion so as to correspond to the opening, and flowing an atmosphere gas inside the batch annealing furnace; A diffusion part positioned below the load plate part while surrounding the flow part, and partitioned by a plurality of diffusion walls provided along an outer side of the flow part to allow atmospheric gas to flow by the flow part; A support part positioned below the diffusion part to support the diffusion part; And a sensing unit connected to the diffusion unit and detecting a deformation of the diffusion unit according to the load of the coil and the atmosphere gas.

The flow unit may further include a flow fan positioned to correspond to the opening and rotating to flow the atmosphere gas; And a fan driver connected to the flow fan to rotate the flow fan.

In addition, the support portion, an upper support portion connected to the diffusion portion (protrusion is formed on the lower surface of the upper support portion); And a lower support part positioned below the upper support part and coupled to the upper support part, wherein an upper surface of the lower support part has a depression formed therein and the protrusion is inserted into the depression part. In the inserted state, the outer surface of the protrusion and the inner surface of the depression are spaced apart from each other, the portion of the lower surface of the upper support portion is not formed and the portion of the upper surface of the lower support portion is not formed This is in contact.

The sensing unit may further include: a sensing bar extending from the diffusion unit (one end of the sensing bar is connected to the diffusion unit, and a sensing tip is positioned at the other end of the sensing bar); A pair of sensing sensors disposed in an up and down direction with the sensing tip interposed therebetween and sensing the sensing tip; And an alarm unit connected to the detection sensors, the alarm unit generating an alarm sound when the detection tip is detected by the detection sensors.

The base of the batch annealing furnace according to the present invention has the following effects.

(1) The base of the batch annealing furnace according to the present invention includes a rod plate portion, a flow portion, a diffusion portion, and a support portion, and anneales the coils loaded in the batch annealing furnace by flowing atmospheric gas. In particular, the support is located below the diffuser and consists of an upper support and a lower support. A protrusion is formed on a lower surface of the upper support, a depression is formed on an upper surface of the lower support, and the upper support and the lower support are coupled by being inserted with the protrusion spaced apart from the recess.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 2 is a perspective view showing the base 100 of the batch annealing furnace according to the preferred embodiment of the present invention, and FIG. 3 is a cross-sectional view illustrating the base 100 of the batch annealing furnace shown in FIG. 2. As shown in Figures 2 and 3, the base 100 of the batch annealing furnace according to the preferred embodiment of the present invention is a rod plate 101, the flow portion 102, the diffusion portion 103, the support portion 104 And a coil C installed on the lower surface of the batch annealing furnace 10 including the inner cover 11 and the outer cover 12 and loaded inside the inner cover 11. 1) and circulate the atmosphere gas of the inner cover 11. The load plate portion 101, the flow portion 102 and the diffusion portion 103 are located inside the inner cover 11. In this case, the coil C is loaded with a strip wound and the inside of the coils C connected.

The loaded coils C are disposed in the load plate part 101, and an opening 111 corresponding to the inner diameter of the coil C is formed. When the coils C are disposed in the load plate part 101, the inside of the coil C and the inside of the base 100 are connected through the opening 111. In addition, the atmosphere gas may be circulated through the inside of the coil C and the inside of the base 100.

The flow portion 102 is located below the load plate portion 101 so as to correspond to the opening 111 of the load plate portion 101. The flow part 102 flows the atmospheric gas of the batch annealing furnace 10 especially the inner cover 11. For example, the atmospheric gas flows into the interior of the base 100 inside the coil C or flows into the interior of the coil C inside the base 100. The flow portion 102 also includes a flow fan 121 and a fan drive 123.

The flow fan 121 is positioned to correspond to the opening 111 of the load plate portion 101 and is rotatable. As the flow fan 121 rotates, the atmosphere gas flows as described above.

The fan driver 123 is connected to the flow fan 121 to rotate the flow fan 121. That is, the floating fan 121 is operated by the fan driver 123. In this embodiment, the fan drive unit 123 is formed of a motor, a pulley, a belt, and the like, but the present invention is not limited thereto. The fan drive unit 123 is a combination of various components capable of rotating the floating fan 121. Can be done.

The diffuser 103 is located below the load plate portion 101 surrounding the flow portion 102, in particular the flow pan 121. The diffusion unit 103 is partitioned by a plurality of diffusion walls 131 provided along the outside of the flow fan 121. When the atmospheric gas flows by the flow part 102, it passes through the diffusion part 103.

The diffusion portion 103 allows the atmospheric gas flowing by the flow portion 102 to flow along the inner wall of the inner cover 11 and the inside of the coil C to be circulated inside the inner cover 11. At this time, the atmosphere gas flows evenly in all directions about the flow part (102).

The support 104 is located below the diffuser 103 to support the diffuser 103. The support 104 is preferably located in all directions about the flow portion 102. For this reason, the diffusion part 103 can be stably located inside the batch annealing path 100, in particular, the inner cover 101. The support 104 also includes an upper support 141 and a lower support 143.

The upper support part 141 is connected to the diffusion part 103. The protrusion 141a protrudes from the central region of the lower surface of the upper support 141.

The lower supporter 143 is located below the upper supporter 141 and is coupled to the upper supporter 141. A depression 143a is recessed on the upper surface of the lower support 143. The protrusion 141a is inserted into the recess 143a, so that the upper support 141 and the lower support 143 are coupled to each other. At this time, the outer surface of the protrusion 141a and the inner surface of the recessed portion 143a are spaced apart from each other, and the lower surface of the upper support 141 in which the protrusion 141a is not formed in the upper support 141 may be a lower support portion ( The lower support part 143 supports the upper support part 141 in contact with a portion of the upper surface of the 143 in which the depression 143a is not formed. In addition, the distance between the outer surface of the protrusion 141a and the inner surface of the recessed portion 143a is preferably 5 mm to 10 mm.

As the protrusion 141a and the recess 143a are coupled in a spaced apart state, only the upper support 141 is thermally expanded even when the diffusion 103 is thermally expanded due to the atmospheric gas. At this time, the protruding portion 141a comes into contact with the recessed portion 143a from a spaced apart state, and is maintained in the inserted state in the recessed portion 143a. For this reason, the support part 104 does not deform | transform, and supports the diffusion part 103 stably.

The sensing unit 105 is connected to the diffusion unit 103 to detect deformation of the diffusion unit 103 according to the load of the atmosphere gas and the coil C. The inclination of the load plate 101 according to the deformation of the diffusion 103 is also sensed by the detector 105. The sensing section 105 is also preferably located in all directions about the flow section 102.

Since the sensing unit 105 detects the deformation of the diffusion unit 103, measures according to the deformation of the diffusion unit 103 may be taken, and damage and breakage of the base 100 may be prevented. In addition, the sensing unit 105 includes a sensing bar 151, sensing sensors 153, and an alarm unit 155.

The sense bar 151 extends downward from the diffuser 103. The diffusion unit 103 is connected to one end of the sensing bar 151, and the sensing tip 151a is connected to the other end of the sensing bar 151. The sensing bar 151 is inclined according to the deformation of the diffusion part 103 and moves up and down. The sensing tip 151a moves with the sensing bar 151.

The sensing sensors 153 are disposed in the vertical direction with the sensing tip 151a interposed therebetween. The sensing tip 151a that moves according to the deformation of the diffusion unit 103 is sensed. When the sensing tip 151a is out of the sensing sensors 153, the diffusion 103 may be excessively deformed and damaged or broken. Therefore, it is detected that the detection sensors 153 may reach a dangerous state by the deformation of the diffusion unit 103 by sensing the detection tip 151a.

The alarm unit 155 is connected to the detection sensors 153 and generates an alarm sound when the detection tip 151a is detected by the detection sensors 153. For this reason, the worker can take the action about the base 100 or the batch annealing furnace 10. That is, the coil C may be annealed stably while preventing damage and damage to the base 100 and extending the life of the base 100 and the batch annealing furnace 10, especially the inner cover 11.

In addition, the description in parentheses in the description of the claims is intended to prevent obscuration of the description, and the scope of the claims of the claims should be construed to include all the items in parentheses.
