Abstract
A continuous annealing system and a continuous annealing method with which it is possible to achieve an annealing atmosphere having a low dew point which is suitable for annealing a steel strip containing easily oxidizable metals such as Si and Mn at low cost and with stability by preventing easily oxidizable metals such as Si and Mn in steel from being concentrated in a surface portion of a steel strip and preventing the formation of oxides of easily oxidizable metals such as Si and Mn.
