It was fulfilled analysis of factors, which influence on the mill length. This is gauge of bar and gauge of cross-section finished section. It is developed mathematical model of rolling gauge formation for cross-section with complex form of cross-section, algorithm of mill length stabilization in conditions of simultaneous influence of bar gauge and gauge of cross-section finished section deviation in deformation in rolling stand. Modeling of mill length stabilization process, which is produced by changing of inter-rolling gap, has showed, that stabilization of mill length lead to destabilization of rolling thickness, but gauge of rolling thickness does not go out of limit borders. Mill length changing without regulation are ± 1 m, rolling thickness - ± 0,1 mm, with regulation – mill length changing ± 0,3m, thickness - ± 0,27 mm.
