METHOD AND FACILITY FOR DRIVING BEARING ROLLERS OF LIQUID METAL CONTINUOUS CAST MACHINE, PARTICULARLY FOR CASTING LIQUID STEEL MATERIALS

摘要

FIELD: metallurgy. ^ SUBSTANCE: method and facility for driving leading bearing rollers (7c) of machine for continuous cast of liquid steel consist in wiring (7) of electrically driven separate leading bearing rollers (7c) or hydraulically installed sections (9) of bearing rollers, and in individual adjustment of torque and frequency of engines rotation (8) of leading bearing rollers by means of adjusting facility (12) for equalising load to drives (10). Facility (12) consists of computing unit (13) determining general torque for all drives (10) with consideration to amount of active drives and average value of torque transmitted to each leading bearing roller (7c) and also considering static base adjustment of torque distribution in form of specific load capability of each leading bearing roller (7c). ^ EFFECT: improved adjustment for equalising load to drives. ^ 15 cl, 3 dwg
