COMPOUND BODY NOZZLE FOR A CONTAINER HOLDING A LIQUID MELT

摘要

A container for a liquid melt has a nozzle with a flow passage. A refractory ceramic material supports the nozzle and an insert of highly wear resistant refractory material limits the flow passage of the nozzle. The insert comprises a shield body or bodies of oxide ceramic or cermet having a thickness of 5% to 20% of the diameter of the flow passage. The flow passage of the shield body is the same or less than the flow passage of the nozzle.
