Control apparatus and method for hot-dip galvanized hot-dip galvanizing system

摘要

Adjusting the height of the cooling box for manufacturing hot and cold zinc-free hot-dip galvanized steel sheet, and adjusting the pressure of the treated water, adjusting the air pressure, and controlling the ammonium phosphate treatment solution supply valve. When the sequencer control information is output to the instrument control computer, the instrument control computer controls the height of the cooling box and the corresponding valve with the received sequencer control information.;When the output of the current form is transmitted to the electric control computer through the analog input / output card through the sequencer control information received from the computer for process control, the electric control computer provides the performance information to the process control computer at a fixed cycle of 10 seconds.
