PRODUCTION OF COPPER OR COPPER ALLOY CLAD STEEL BY MELTING METHOD

摘要

PURPOSE:To manufacture a satisfactory copper or copper alloy clad steel plate without shrinkage cavity and variance in strength by abutting a heat insulating or heating member on the end part of the circumference of the steel plate and pouring a molten cladding material of copper or copper alloy atop the steel plate. CONSTITUTION:A heat insulating material or heater is pessed via a flask plate to the end edge of the circumference of a steel plate consisting of a base material. Molten copper or copper alloy to be clad is poured atop the base material. The end part which is cooled faster is heat insulated in this case and therefore the solidification progresses uniformly and the generation of shrinkage cavity and variance in strength is obviated. A much better result is obtd. if the surface of the molten metal is covered with a suitable flux.
