1. [Complete annealing] Method: heat the workpiece to the critical temperature, hold the heat for a period of time, then power off, close the furnace door, the workpiece slowly cooled to room temperature with the furnace temperature

2. [Complete annealing] will take a long time

3, [continuous annealing] the workpiece in the relatively long furnace path continuously go forward, the furnace path temperature is also constantly falling, the high temperature at the entrance, the outlet is close to room temperature, so faster

4. The quality of [continuous annealing] is not as good as [complete annealing]. Sometimes, the metallographic structure cannot be completely reduced to austenite
