Embodiment 1
[0052] Taking 4 tapping heats as an example, the 4 tapping heats are numbered 1, 2, 3, and 4 respectively. see figure 1 and figure 2 , the slab tapping of the current heat is controlled by the control unit, and the walking beam is controlled to move downward, and the slab of the current heat is transported to the tapping roller table through the walking beam. The detection unit detects the position of the walking beam by multiple times of repeated detection. When the judgment unit judges that the walking beam has moved to the lower limit position, the judgment unit sends a feedback signal to control the detection unit to stop detecting the position of the walking beam. The judgment unit obtains the position data of the walking beam from the detection unit, and judges whether the walking beam has moved to the lower limit position. The tapping roller table control unit obtains the judgment result from the judging unit. When the walking beam moves to the lower limit position, ...
