The first timing unit, the second timing unit and the third timing unit may all use timers. When the tapping machine is started, the first timing unit starts timing, and after the slab is drawn out from the tapping machine, the first timing unit finishes timing and outputs a timing result to the control module 02. Similarly, the second timing unit and the third timing unit may also adopt similar timing modes and timing rules to feed back the timing result to the control module 02.
