Title:
MOLDING COMPOSITE REFRACTORY MEMBER
Document Type and Number:
Japanese Patent JPS56128665
Kind Code:
A
Abstract:
Method for making a refractory valve is disclosed. The sliding gate valve slide plate in a can has an integral collector nozzle and is formed as two conjoined refractory concrete mouldings with a cup or trough shaped metal foil lying in the joint therebetween. The foil is oxidisable in service to form a bond between the concretes. The concretes may be of different formulations, and the moulding with which molten metal makes contact is preferably the more resistant to the rigorous environment presented by flowing molten metal. The slide plate is cast in two steps using the shaped foil and the can as respective lost mould members which coact with a planar polished surface to produce a cast slide plate needing effectively no finish grinding before installation in a valve.
