Uninterrupted Production of Metal Coils by Making Successive Joints with Roll Bonding Technique

抄録

The aim is to develop an uninterrupted processing route to manufacture metal coils, so that the efficiency of production, as well as the quality of the product and the cost-efficiency can be improved. The traditional method of joining two metal sheets is by welding; however the welding process itself can easily introduce additional processing steps and pile up the cost of production. In the past, joining two metal sheets with identical composition by the rolling process has not been easy. The present study induces dissimilarity between two sheets, i.e. pre-heat treatment for one plate to result grain growth. Experimental results indicate that such introduction of dissimilarity between two metal parts can significantly improve the roll bonding process, not only making the joint much stronger than the traditional welding technique, this newly developed method can enhance the efficiency of the production of metal coils in industries.
