The present invention relates to a heat treatment furnace, and more particularly to a heat treatment furnace that can prevent the deformation of the material by continuously heat-treating a metal material such as a thin plate wound on the roller or a lead frame of the semiconductor.

In general, a heat treatment furnace refers to an apparatus for obtaining a desired property and state by heating a workpiece having a metal material to an appropriate temperature and then cooling the workpiece.

That is, a device that can effectively heat-treat a thin plate or a metal material of a lead frame of a semiconductor using such a heat treatment furnace has been disclosed in Korean Patent Publication No. 0007156 (Anti-oxidation Heat Treatment Furnace).

When explaining the configuration of the invention, the uncoiler and recoiler to freely rotate or wind the material while rotating freely, the drive means for pulling the material in one direction while using the motor as the driving source and the roll feed as the towing medium, It comprises a guide means for controlling the flow of left and right, a heating device using a heating wire using an electric resistance wire and a cooling device using a cooling water passage while having roller feed media, and a frame supporting them.

However, in the case of the heat treatment furnace as described above, as the overall configuration and the work system is installed horizontally performed, a roller, which is a conveying means of the material, was required, and thus the friction area between the material and the roller was inevitably increased. As a result, the rollers are worn and there is a need for frequent replacement, and in order to reduce the contact area between the roller and the material by attaching a carbon ring to the center of the roller to minimize the friction area, in this case, When the material is torn due to carbon, and when the thickness of the material is 0.1 mm or less, the material is torn due to its own weight and the coiling force of the recoiler. There was no problem. In addition, as the heat treatment system is carried out horizontally, the heating device in the heating chamber was also forced to be installed horizontally. As a result, the temperature distribution was biased upward, resulting in a temperature difference between the points, resulting in uneven surface gloss of the material. There was a problem, and as the system was installed horizontally, the installation space was restricted, and thus there was a problem that the space utilization was lowered.

In addition, when the roller installed in the cooling chamber is broken, there is a problem in that the core tube in the heating chamber and the cooling tube installed in the cooling chamber collide with each other, resulting in damage or leakage of gas.

Therefore, the object of the present invention for solving the problems as described above is to produce a material having a thickness of 0.1 mm or less by vertically transporting the material by self-weight by installing the entire configuration of the heat treatment furnace and the work system vertically This is possible, and also to provide a heat treatment furnace that does not require a roller that is the conveying means of the material.

Another object of the present invention is to vertically distribute the internal temperature of the heat treatment furnace to uniformly distribute the internal temperature to uniform surface gloss of the material, and to provide a high heat efficiency furnace.

Another object of the present invention is to install each position control device (EPC) to the uncoiler and the recoil to be unwound and wound, so that the coil is biased to one side when the material is wound. It is to provide a heat treatment furnace that can prevent that.

Still another object of the present invention is to provide a flow apparatus having respective guide tubes and nonwoven fabrics between the core tube of the heating apparatus and the cooling tube of the cooling apparatus, so that the apparatus can be expanded or contracted when the core tube is contracted or expanded. It is to provide a heat treatment furnace that can prevent damage by preventing collision between the core tube and the cooling tube.

The present invention for achieving the object as described above, in the heat treatment furnace having an uncoiler and a recoiler to release or wind the material, it is located in the rear of the uncoiler to control the position of the material wound with the recoiler EPC, a heating device which is located on the upper part of the EPC and a material conveying pipe is installed in the lower part, and a core is installed in the lower part to transfer the material, and a flow device installed between the material conveying pipe and the core core pipe, Located on one side of the heating device, the cooling device having a cooling tube therein, the gas injection device is installed on one side of the cooling tube, and the upper portion of the heating device and the cooling device is installed on both sides of the material transfer pipe Carbon roller, and the gas discharge blocking device installed in the lower end of the cooling device and the material conveying pipe, the heat treatment furnace configured as described above is a vertical frame It characterized to be installed perpendicular to the horizontal frame.

On the other hand, by installing a flow device 22 having respective guide pipes 54, 56 and nonwoven fabric 58 between the core pipe 50 and the material transfer pipe 34a, the core core pipe 50 By preventing the collision with the material feed pipe 34a during contraction or expansion of the core core 50 and the material feed pipe 34a to prevent damage to prevent the above-mentioned gas is discharged to explode. .

After that, the material 100 transferred through the above process again prevents the material 100 from being biased to one side via the EPC 12, and is subjected to the recoiler 14.

As described above, the present invention is capable of producing a material having a thickness of 0.1 mm or less by transferring the material in a free-falling manner by installing the entire configuration of the heat treatment furnace and the work system vertically. The roller does not need to be a conveying means, and by installing the heating device of the heat treatment furnace vertically, the internal temperature is uniformly distributed to make the surface gloss uniform, and the uncoiler is uncoiled and wound. By installing the respective EPCs in the and the recoiler, it is possible to prevent the coiling from being biased to one side when the material is wound. In addition, a flow apparatus having respective guide tubes and nonwoven fabrics is provided between the core tube and the cooling tube of the cooling apparatus to prevent collision between the core tube and the cooling tube by the flow apparatus when the core tube is contracted or expanded. By doing so, there is an advantage of preventing damage.
