Beschreibung
Zusammenfassung:	In the present specification, disclosed are a direct heating annealing device, a control method thereof, and a method of manufacturing stainless steel using the same, capable of preventing overheating of an edge of a steel plate and allowing manufacture of stainless steel with a uniform material by uniformly controlling an internal temperature of an annealing device while using a direct heating annealing device. The direct heating annealing device according to an embodiment of the present invention may comprise: a housing provided in a hexahedral shape; a burner part including a plurality of burners provided to face the inside of the housing; and a control part that controls the burner part to uniformly control the internal temperature of the housing. 본 명세서에서는 직접 가열식 소둔장치를 이용하면서도 소둔장치 내부 온도를 균일하게 조절함으로써, 강판의 에지(edge)부 과열을 방지하여 균일한 재질을 갖는 스테인리스강을 제조할 수 있도록 하는, 직접 가열식 소둔장치 및 그 제어방법과 이를 적용한 스테인리스강의 제조방법에 관한 것을 개시한다. 본 발명의 일 실시예에 따른 직접 가열식 소둔장치는, 육면체 형상으로 마련되는 하우징; 상기 하우징의 내측을 향하도록 마련되는 복수개의 버너를 포함하는 버너부; 및 상기 하우징의 내부 온도를 균일하게 조절할 수 있도록 상기 버너부를 제어하는 제어부를 포함할 수 있다.
