Production control method for 460mm section blank of wide and thick plate heating furnace

The invention discloses a production control method for a 460mm section blank of a wide and thick plate heating furnace, which relates to the technical field of ferrous metallurgy and comprises the following steps of: presetting a size range and a weight threshold value of the blank allowed to enter the heating furnace; whether the size of the blank exceeds a preset size range or not is judged, whether the weight of the blank exceeds a weight threshold value or not is judged, and the blank is allowed to enter the heating furnace only when the size of the blank does not exceed the preset size range and does not exceed the weight threshold value; presetting a threshold value of the steel loading spacing of the blanks, and controlling the steel loading spacing of the blanks to be greater than the threshold value; and carrying out steel loading action acquisition, position tracking and steel tapping action acquisition on each blank. By optimizing production control of the 460mm section blank, accurate positioning
