Abstract

In this article, the results of experimental and analytical research of the electric drive of continuous casting machine and the way it affects the quality of the cast slabs are presented. It is shown that pulling roll barrels deformation, which is bending or wear, leads to the slabs quality reduction since the deformed roll barrels apply additional static and dynamic forces to the slab during crystallization process. The methods that make it possible to estimate the rolls defect influence on the slab quality are presented. As a research result the new technological demands to the continuous casting machine electric drive were designed and tested, which is described in the paper.

Keywords

Continuous casting machine electric drive, pulling out strengths, continuous cast slab quality, pull out rolls, pulling out strength stability.
