摘要

The automatic system for addition of casting powder in steel manufacture by continuous casting involves each continuous casting line comprising several controlled feed devices (1), each subdivided into various hoppers (2) fitted with discharge mouthpieces (3). The mouthpieces are arranged in accordance with a primary virtual circumference (4) which only in one of its points is liable to coincide with the vertical of a collector (5) connected to the ingot production unit of the continuous casting line in question. Each of the controlled feed devices is associated with rotary impulsion units with successive stopping points in which the discharge mouthpieces of the hoppers coincide with the vertical of a collector which has a fixed position.
