CALCULATING THE EFFECT OF TECHNOLOGICAL GAPS IN THE COMPONENTS OF A CONTINUOUS CASTER ON THE LEAD TIME

摘要

The casting of steel on a continuous caster is the culmination of interactions that take place between the pouring equipment, mold, secondary cooling zone, and ingot withdrawal mechanism in a single process. Studies of the continuous casting of steel have shown that the stability of the continuous casting operation should be evaluated based on the criterion of lead time. Gaps in the components of the caster have a direct effect on the velocities of the mold and the ingot, which in turn determine the lead time. Hundreds of continuous-caster strands equipped with mold oscillation mechanisms of the hinge-lever type and hinged multi-component dummy bars have been in use in many countries up to the present. Thus, the effect of gaps in the caster components that determine the quality of the cast semifinished product is an important problem and needs to be resolved.
