Control system for counting steel passing length of shear blade of scrap cutter

The invention relates to the technical field of control, in particular to a control system for counting the steel passing length of a shear blade of a scrap shear. The system comprises a control module, a length statistics module and a quantity statistics module, the length statistics module is used for carrying out statistics on the steel passing amount length of each shear blade of the acid rolling mill unit so as to obtain a steel passing amount length data set; the quantity statistics module is in communication connection with the length statistics module; the counting module is used for counting the steel passing quantity based on the steel passing quantity length data set obtained by the length counting module so as to obtain steel passing quantity data; and the control module is used for controlling the shearing action of the pickling rolling unit. The use state of the scrap cutter blade is controlled, the purposes of reducing scrap cutter system faults and reducing the shutdown of an acid rolling unit
