The heat treatment stations are preferably arranged on the same side of the traversing rail 1, although it is also an alternative to arrange on different sides of the traversing rail 1.
It will be appreciated that the above-mentioned side-moving lower roller table 3 can input the steel sheet stack 6 into the heat treatment station, and can also retract the steel sheet stack 6 output from the heat treatment station onto the steel sheet transport vehicle 2, so that the conveying roller of the above-mentioned side-moving lower roller table 3 can be positively and negatively rotated, i.e. the configured driving motor is a positive and negative rotating motor. The conveying direction of the side-shifting lower roller way 3 is perpendicular to the guiding direction of the transverse moving track 1, namely, the axial direction of the conveying roller of the side-shifting lower roller way 3 is parallel to the guiding direction of the transverse moving track 1.
