The monitoring system mainly completes the display and recording of the state data in the production process by the monitoring software running in the system.

To increase the length of the steering roller in the quenching water tank to ensure the stable operation of the strip in the cooling tower area. Pre-spray is provided in front of the quenching tank to ensure that the strip temperature is less than 40℃ when the strip is going into finishing and straightening section. The surface of steering roller in the quench water tank is chromed. After quenching, the strip is dried by squeezing and drying. The surface of the squeeze roll is neoprene. The roll on the entry of quench tank has electric correction function.
