A Method Of Forging Crankshafts From Continuous Cast Billets
Abstract: The present invention eliminates one of the steps from a typical conventional process of manufacturing complex parts such as crankshafts. This achieves the purpose of reduction in the cost of production as well as carbon footprint of the whole process. The present invention eliminates the rolling and/or cogging process from the complete crankshaft manufacturing cycle. The rolling and/or cogging process reduces the cross section of the cast material to a section which can be used by the closed die forging process. The invention accomplishes the said requirement by using ConCast billets of the size required by the forging process, thus, eliminating the requirement of cross section reduction through rolling and/or cogging. Moreover, proper forging process design is done to take care of closure of internal porosities and centre looseness, breaking of as cast structure and required grain flow during the forging operation. Thus, the crankshaft produced by the invented process has properties (mechanical, metallurgical, fatigue) equivalent to those produced by the conventional process.
