Method and device for reducing cutting loss of reinforcing steel bar, medium and electronic equipment

The invention relates to the technical field of steel bar rolling, and discloses a method and device for reducing cutting loss of a steel bar, a medium and electronic equipment. The method comprises the steps that the first length of a steel billet and the second length of a steel bar are obtained, and the steel bar is formed by rolling the steel billet through a rolling mill; based on the first length and the second length, the conversion coefficient of the steel billet and the steel bar is determined, and the conversion coefficient is used for representing the proportional relation between the length of the steel billet and the length of the steel bar; obtaining a fixed length, wherein the fixed length is the length of the target finished reinforcing steel bar; based on the fixed length, the double-length shearing length is determined, and the double-length shearing length is the specific length required by a double-length flying shear located behind a rolling mill to shear the target reinforcing steel bar;
