Presently, continuous casting machines are widely used in metallurgical industry for production of high quality billets. And the maximum economic and resource-saving effect is achieved by the use of continuously casting small-section billets. Proceeding to the continuous casting has tightened the requirements for product quality and the main objective has become to determine the factors influencing the billet quality. It is necessary to design competently a zone of secondary cooling, for improvement of quality of production. Having changed her design and as a result the loadings operating on a zone of secondary cooling will decrease and the rigidity of a design will increase.

The paper shows how to calculate the loads on conveyor rollers at different positions of the conveyed billet. It also contains the diagrams of conveyors with different types of drives and loading diagrams as well.

The paper shows an algorithm for determining the load on the electric motor of run-out conveyor starting from determination of the first moment of no load operation during slab conveying, slipping torque of the rollers along the surface of the conveyed billet and ending with the choice of the electric motor. It also covers an algorithm for strength calculations of the run-out conveyor roller, which includes the calculation of the moments and forces acting on the conveyor roller and its supports, the calculation of static strength and torsion strength, calculation of roller deflection of the conveyor rollers as well as the selection and verification calculation of conveyor roller bearings.
