Abstract The technology of fixed-weight billet supply was developed to meet the requirements of bar rolling. These methods include 4 parts, i.e. ignoring influence of technologcial conditions, enhancing maintenance of withdrawal-straightening machine, improving cutting precision of casting blank and designing and making the weighting. The fixed-weight percent is beyond 70% in the standard weight ±5kg via feedback control system, which is the foundation of rolling. It was found in service that, the fluctuation of casting speed is the first factor. When casting speed fluctuation is below 0.05, the change of density for continuous casting strand is little.
