“…Laminar cooling control system adjusts water flow by turning on or off valves of headers. Strip is cooled from finish rolling temperature (800˚C～˚C900 ˚C) at exit of finishing mill to required coiling temperature (550˚C～700 ˚C) during laminar cooling process [7]. Control system of laminar cooling includes basic automation system and process automation system [8].…”

Coiling temperature, finish rolling temperature and running speed of ZSAC1 strip during U-type cooling and number of valves which had been turned on were analyzed in order to find out the reason of low coiling temperature at tail of ZSAC1 strip in U-type cooling process. Results of research showed that running speed of strip and finish rolling temperature were main factors affecting accuracy of coiling temperature. Coiling temperature decreased with the increase of running speed of strip. Coiling temperature fluctuation would occur at the same part of strip when finish rolling temperature increased or decreased. Holding rolling speed and rolling temperature of strip stably can improve accuracy of coiling temperature during downstream U-type cooling.

“…At present, Simulation platform technology has been widely applied in different fields, playing an indispensable and invaluable role in the industrial process control system and the design of weapon equipment system, such as the laminar cooling system. Laminar cooling system is to cool the strips from the austenitic finishing temperature (800~900℃) down to the ferrite coiling temperature (550~700℃) with an appropriate cooling rate, by controlling the applied cooling water quantity and the runout table velocity [1][2][3]. To reduce cost and meet the requirements of repeat trials, it is necessary to design and develop simulation platform [4][5][6].…”

The laminar cooling process has complex features, such as nonlinear, time-varying parameters, frequent changes of working conditions, and its difficult to achieve precise modeling and the traditional closed-loop control. A multi-layer virtual experiment platform with hybrid programming of configuration is proposed in the paper. Not only does this platform keep the environment similar to the industrial field, but also saves money on purchasing the hardware system.

Abstract. Water flow and number of valves turned on were analyzed in order to find out the reason of low coiling temperature at tail of strip during U-type cooling process. Result of research showed that actual value of number of valves turned on in micro zone at tail of strip was not consistent with the corresponding calculated value of valves turned on. Then actual value of water flow at tail of strip was not consistent with the corresponding calculated value of water flow. That was the reason of low coiling temperature at tail of strip during U-type cooling process. The improvement measure was compensation adjustment for response time of valves. After improving, actual value of number of valves turned on in micro zone was consistent with the corresponding calculated value of valves turned on and high accuracy of coiling temperature at tail of strip was obtained.
