본 발명은 열처리 방법 및 장치에 관한 것으로, 더욱 상세하게 설명하면, 풍력발전기용 메인 샤프트를 제작하기 위한 열처리 방법 및 장치에 관한 것으로, 대차로를 통해 가열된 메인 샤프트를 회전 롤러가 장착된 수냉조를 통해 냉각시킨 다음, 유냉조를 통해 2단계로 냉각시켜 담금질(Quenching)한 후, 이를 다시 대차로를 통해 가열시켜 뜨임(Tempering) 함으로써 메인 샤프트 전체의 냉각이 균일하여 이루어져 표면에 크랙이 발생하지 않고 변형이 발생하지 않는 풍력발전기용 메인 샤프트의 열처리 방법 및 장치에 관한 것이다.The present invention relates to a heat treatment method and apparatus, and more particularly, to a heat treatment method and apparatus for manufacturing a main shaft for a wind turbine, and a water cooling tank equipped with a rotating roller for a main shaft heated through a bogie road. After cooling through, and then quenching by cooling in two stages through an oil-cooling tank, and then heating it through a bogie to temper it to uniformly cool the entire main shaft so that cracks do not occur on the surface. The present invention relates to a method and apparatus for heat treatment of a main shaft for a wind power generator without deformation.

일반적으로 열처리라 함은 금속 재료를 융점 이하의 온도로 가열하고 냉각속도를 선택적으로 가감하여 필요로 하는 조직 및 성질을 갖게 하는 조작으로서 담금질과 풀림, 불림 및 뜨임 등이 있다.In general, heat treatment refers to an operation of heating a metal material to a temperature below the melting point and selectively adding or decreasing a cooling rate to obtain a necessary structure and property, such as quenching, loosening, soaking and tempering.

이러한 열처리를 통해 금속 또는 합금에 요구되는 성질, 즉 강도, 경도, 내마모성, 내충격성, 가공성, 자성 등의 제반 성능을 부여하여 금속이 쓰이는 곳에 적합하도록 가공되는 구성을 갖는다.Through such heat treatment, the metal or alloy has properties such as strength, hardness, abrasion resistance, impact resistance, workability, and magnetic properties, so that the metal is processed to be suitable for use in the metal.

상기 열처리에 있어서, 풍력발전기 등에 사용되는 메인 샤프트의 경우에는 그 크기 2 내지 3m가 될 정도로 그 규모가 대단히 커서 대차로를 통해 가열한 후 물 또는 기름을 이용하여 냉각시킬 경우에는 전체적으로 냉각의 불균형이 발생하여 표면이나 심부에 크랙이 발생하여 내구성이 현저히 저하될 우려가 있었고, 뿐만 아니라 열 구배에 따른 변형이 발생하게 되어 완성된 메인 샤프트가 원하는 형상대로 제작되지 않아 비용과 시간 손실을 초래하는 문제점을 내포하고 있었다.In the heat treatment, in the case of the main shaft used in the wind turbine, etc., the size is so large that the size is 2 to 3 m, and when the heat is heated through the bogie and then cooled by using water or oil, the cooling imbalance is generally reduced. There was a possibility that the cracks occurred on the surface or the core and the durability was significantly lowered. Furthermore, the deformation caused by the thermal gradient occurred, and the main shaft was not manufactured in the desired shape, resulting in cost and time loss. It was implicated.

이에 본 발명은 상기와 같은 문제점을 감안하여 발명한 것으로, 대차로를 통해 850℃에서 14 내지 16시간 가열한 후, 이를 830℃로 낮추어 2시간 동안 유지시킨 메인 샤프트를 롤러가 구비된 회전 수냉조에 투입하여 45 내지 50분간 메인 샤프트를 회전시키면서 냉각시키고, 이를 유냉조에 다시 투입하여 150분간 냉각시켜 담금질을 완료한 후, 다시 대차로에 장입하여 600℃로 5시간 동안 예열작업을 거친 다음 625℃로 15 내지 17시간 유지하여 뜨임 함으로써 전체적으로 균일하게 냉각되어 표면에 크랙이 발생하지 않고 변형이 일어나지 않으며, 양호한 조직과 기계적 성질을 향상시키도록 함을 목적으로 한다.Therefore, the present invention was invented in view of the above problems, and after heating at 850 ° C. for 14 to 16 hours through a trolley, it was lowered to 830 ° C. and maintained for 2 hours in a rotating water cooling tank equipped with a roller. After rotating the main shaft for 45 to 50 minutes by rotating it, it was added to the oil cooling tank again and cooled for 150 minutes to complete the quenching, and then charged into a trolley again, followed by preheating at 600 ° C. for 5 hours, followed by 625 ° C. It is aimed to improve the good structure and mechanical properties by maintaining the temperature in the furnace for 15 to 17 hours and then uniformly cooling the entire surface to prevent cracking and deformation.

본 발명은 풍력발전기용 메인 샤프트의 열처리 방법 및 장치에 관한 것으로, 대차로를 통해 가열된 메인 샤프트를 롤러가 장착된 수냉조를 통해 냉각시킨 다음, 유냉조를 통해 2단계로 냉각시켜 담금질(Quenching)한 후, 이를 다시 대차로를 통 해 가열시켜 뜨임(Tempering) 함으로써 메인 샤프트 전체의 냉각이 균일하여 이루어져 표면에 크랙이 발생하지 않고 변형이 발생하지 않는 특징이 있다.The present invention relates to a method and apparatus for heat treatment of a main shaft for a wind turbine.
