Description

진공로의 가열장치{APPARATUS FOR HEATING VACUUM FURNACE}[0001] APPARATUS FOR HEATING VACUUM FURNACE [0002]

본 고안은 진공로의 가열 장치에 관한 것으로, 수명 단축을 방지하여 장기간 이용할 수 있는 진공로의 가열 장치에 관한 것이다.The present invention relates to a heating apparatus for a vacuum furnace, and relates to a heating apparatus for a vacuum furnace that can be used for a long period of time by preventing shortening of life.

진공로는 진공상태에서 금속을 용해하기 위한 것으로 오염이 없고 금속 중의 가스 함유량을 낮출 수 있다. 또한, 진공로는 금속을 열처리하기 위해 이용되는데, 금속을 적당한 온도로 가열한 후 냉각시키면서 금속 내부의 결정 변화에 따른 금속의 특성을 변위하는 방식으로 열처리가 이루어진다. 이와 같이 진공로에서 열처리가 수행된 금속은 경도가 높고 변형이 적으며 내마모성이 향상되어 공구강이나 내열강 등 특수금속 등에 적용되고 있다.A vacuum furnace is used to dissolve a metal in a vacuum, and it is free from contamination and can reduce gas content in the metal. In addition, a vacuum furnace is used for heat-treating a metal. The metal is annealed in such a manner that the metal is heated to a proper temperature and then cooled to change the characteristics of the metal according to crystal changes inside the metal. As described above, the metal subjected to the heat treatment in the vacuum furnace has high hardness, little deformation, and has improved wear resistance and is applied to special metals such as tool steel and heat resistant steel.

진공로를 이용하여 금속을 용해하거나 열처리를 하는 경우, 금속을 진공로의 내부에 장착한 후에 내부를 진공으로 가압한 상태로 가열하고 소정 시간 후에 냉각수단을 통하여 냉각시키는 과정을 거친다. 이때, 진공로 내부의 온도는 1200℃ 이상까지 상승하도록 열이 발산되며, 냉각 과정에서 냉기가 진공로 내부에 순환되어 내부에 수분이 발생하게 되며, 공기와 수분으로 인해 진공로의 가열장치의 수명이 단축되는 문제가 있다.In the case of dissolving or heat treating a metal by using a vacuum furnace, the metal is placed inside the vacuum furnace, and then the inside is heated in a state of being pressurized under vacuum, and cooled through a cooling means after a predetermined time. At this time, heat is radiated so that the temperature inside the vacuum furnace rises up to 1200 ° C or more. During the cooling process, the cold air is circulated inside the vacuum furnace and moisture is generated therein. Because of the air and moisture, There is a problem that this is shortened.

본 고안은 진공로 내부에서 수분 발생을 방지하여 수명 단축을 방지할 수 있는 진공로의 가열장치에 관한 것이다.The present invention relates to a vacuum furnace heating device capable of preventing moisture from being generated inside a vacuum furnace to prevent shortening of life span.

본 고안은 금속을 용해하거나 열처리하는 가열챔버와; 상기 가열챔버에 장착되는 발열수단을 포함하며, 상기 가열챔버는 카본 또는 세라믹 보드로 구성되는 내열부재와 세라믹 울로 구성되는 절연부재로 구성되는 진공로의 가열장치에 관한 것이다.The present invention relates to a heating chamber for dissolving or heat treating a metal; And a heating unit mounted in the heating chamber, wherein the heating chamber is composed of a heat-resistant member made of carbon or a ceramic board and an insulating member made of ceramic wool.

여기서, 가열챔버는 카본으로 구성되는 내열부재 내주면에 세라믹 울로 구성되는 절연부재가 결합되고, 상기 세라믹 울로 구성되는 절연부재 내주면에 세라믹 보드로 구성되는 내열부재가 결합할 수 있다.Here, the heating chamber may be formed by an insulating member formed of ceramic wool on the inner circumferential surface of the heat-resistant member formed of carbon, and a heat-resistant member formed of the ceramic board may be coupled to the inner circumferential surface of the insulating member formed of the ceramic wool.

본 고안은 진공로를 이용하여 금속을 용해하거나 열처리한 후 냉각시키는 과정에서 진공로의 가열장치에 수분이 발생하지 않기 때문에 진공로의 가열장치의 수명이 단축되는 것을 방지할 수 있어 장기간 이용할 수 있다.Since the present invention prevents moisture from being generated in the heating device of the vacuum furnace during the process of dissolving or heat-treating the metal by using the vacuum furnace, the lifetime of the heating device of the vacuum furnace can be prevented from being shortened, .
