Forging forming method of large piston rod forgings
The large piston rod forging is an important part of a certain type of ship with adjustable pitch propeller device, the material is 42CrMo steel, the middle is a large-flange, both ends are steps, the cross-sectional size changes are large. In the work by torsion, impact and other loads, high technical requirements. The manufacturing process of the piston rod is as follows: electric furnace smelting → vacuum refining → forging → heat treatment after forging → rough machining → ultrasonic testing (internal control) → quenching tempering → sampling and marking → testing → ultrasonic testing → * * * final processing → dimensional inspection → marking and delivery.

Technical Measures for Special Alloy Forging
Special alloy forging is much more difficult than ordinary carbon steel and low alloy structural steel. To produce special alloy forgings with geometric dimensions and metallurgical quality that meet the requirements, corresponding targeted technical measures must be taken according to different characteristics. These measures mainly include process measures, forging and die design measures, quality control, forging performance (selection of thermodynamic parameters based on) testing and simulation of the forging process.
