METHOD FOR PROCESSING STEEL TWO PIECE CAN WITH SUPERIOR SURFACE BRIGHTNESS AND STRIPPABILITY

摘要

PURPOSE: A method for processing a steel two piece can with superior surface brightness and strippability is provided to improve surface brightness compared to a can formed by a conventional method and greatly improve strippability due to decrease of roll back by appropriately controlling processing and forming conditions. CONSTITUTION: In a processing method for processing a steel two piece can by drawing and ironing can processing, the method for processing the steel two piece can with superior surface brightness and strippability is characterized in that a can in which drawing and ironing process is performed in an ordinary manner is limited to the thickness reduction ratio range of 7 to 10% in burnishing process.
