Claims6
A method for making a tubular mold having rectangular or square shaped cross section to be used for continuous casting of high melting metals such as steel comprising the steps of:
- providing a round tube made of copper or a copper alloy by means of press working and/or rolling and/or drawing;
- electrolytically depositing a wear resisting coating on the inside surface of the round tube as made to produce a compound tube having a wear resisting uniform coating on the inside;
- and
- subsequently forming the round tube into a tube with rectangular or square-shaped cross section.
