Method for reducing load current of finished deformed steel bar

The invention discloses a method for reducing load current of a deformed steel bar finished product, which relates to the technical field of deformed steel bar rolling and comprises the following steps: obtaining the size of a rolling pass according to the sectional size and the elongation coefficient of the deformed steel bar finished product; on the basis of the width and the depth of the flat oval hole pattern, whether the tooth form can be filled with the size of the rolling hole pattern or not is checked, and the width and the depth of the rolling hole pattern are obtained after checking; and based on the width and depth of the rolling hole pattern, a hole groove matched with the rolling hole pattern is formed in the roller surface of the roller. According to the invention, on the basis of ensuring that each size of the deformed steel bar accords with the national standard, the current of a finished product is reduced, support is provided for improving the machine-hour yield, meanwhile, on the basis of r
