Zusammenfassung:	Disclosed is a continuous annealing furnace. According to the present invention, the continuous annealing furnace comprises: a heating section in which a strip which has passed through a cold rolling process is heated; a slow cooling section into which the strip heated in the heating section is introduced, and in which the strip is cooled; a rapid cooling section into which the strip cooled in the slow cooling section is introduced, and in which the strip is cooled as cooling gas is sprayed; and a gas curtain formation unit disposed in the rapid cooling section and forming a gas curtain to suppress discharge of the cooling gas. 연속 소둔로에 대한 발명이 개시된다. 본 발명의 연속 소둔로는: 냉간 압연 공정을 거친 스트립이 가열되는 가열대; 가열대에서 가열되는 스트립이 유입되고, 스트립이 냉각되는 서냉대; 서냉대에서 냉각되는 스트립이 유입되고, 냉각가스가 분사됨에 따라 스트립이 냉각되는 급냉대; 및 급냉대에 배치되고, 냉각가스의 배출을 억제하도록 기체커튼을 형성하는 기체커튼 형성부를 포함하는 것을 특징으로 한다.
