Marin crankshaft is a bottleneck in China＇s shipbuilding industry restricting sustainable development. This article describes the forging process of the Type 60 machine crank that uses a bending method. This paper analyzes the causes of the forging defects by computer simulation, and proposes several measures to optimize the forging process and standardize the forging operation. Based on the research, super-large marine crankshaft forging is successfully developed.
