VERFAHREN ZUM FREIHALTEN DES DURCHFLUSSKANALS VON SCHIEBEVERSCHLUESSEN AN STRANGGIESSANLAGEN.

摘要

A process is claimed for maintaining the melt passage open during controlled pouring esp. of molten steel from a tundish through a sliding closure into a continuous casting mould, while maintaining a controlled target degree of filling using the sliding closure in a choked position, the closure passage being flushed open by an opening procedure. The slide plate is displaced from a choked position back into a choked position by a smooth opening stroke at a speed dependent on the effect of the additional melt amt. on the target filling degree control.
