Refractory plates for slide gate valves, the use of molten raw materials as materials for such plates and melting vessels comprising such plates

摘要

The present invention is a refractory plate for a slide gate valve for controlling the flow rate of liquid steel, the use of molten raw material as a material for such a plate, and a melting vessel for receiving liquid steel comprising such a plate for controlling the flow rate of liquid steel from the melting vessel. It is about.
