APPARATUS FOR REGULATING THE FLOW OF MOLTEN METAL

摘要

This invention is concerned with a sliding nozzle device for applying a predetermined sealing pressure between a stationary refractory plate and a sliding refractory plate of the sliding nozzle for achieving the complete regulation of pouring of molten metal from a ladle vessel. A desired press means, which can be replaceable mounted on the sliding nozzle if desired, is provided for urgingly pressing the sliding plate toward the stationary plate without necessitating conventional manual force. The sliding nozzle is advantageously shaped so as to allow mounting of the above press means thereon and to maintain the sealing pressure between the refractory plates during the operation of the sliding nozzle.
