The excessive water vapor affects the laser speed meter emitted by the speed meter. The speed meter cannot receive the detection laser signal, resulting in a drop in speed (zero speed), which directly affects the cutting of the strip. In severe cases, the steel is stuck and the rolling is stopped. Therefore, accurate detection by the speed meter is an indispensable condition for the stable operation of the production line.
