Shanxi Jianing Forging has collected real-world engineering cases of long shafts, short shafts, drive shafts, and marine nuclear power shaft forgings, fully showcasing the forging process of shaft forgings, finished product precision, and practical application scenarios for heavy equipment.
In shipbuilding, shaft forgings, as key transmission components, have material properties and machining accuracy that directly affect the safety and reliability of ship operation. Recently, Jianing Forging provided a shaft forging solution for a ship parts factory in Cangzhou, Hebei, addressing multiple technical challenges faced by customers in traditional procurement.
A ship parts factory in Cangzhou, Hebei, has long undertaken axle system processing tasks for medium and large ships, with strict requirements for internal structural uniformity, fatigue strength, and dimensional tolerances of forgings. Previously, the company purchased shaft forgings from multiple suppliers, often experiencing performance fluctuations between batches and excessive machining allowances, resulting in long subsequent machining times and a high defect rate.
The core pain points faced by customers include: first, internal defects in raw materials that are difficult to control, with some forgings detecting tiny cracks or inclusions during ultrasonic testing, which affects product pass rates; Second, the dimensional consistency of forgings is poor, requiring separate adjustment of machining parameters for each batch, slowing down production pace; Third, traditional forging processes result in thick surface oxide scale, increasing subsequent cleaning costs; Fourth, supplier delivery times are unstable, often affecting ship assembly progress.
To address these pain points, Jianing Forging offers systematic solutions from four aspects: material control, forging processes, heat treatment, and finishing: selecting high-quality alloy billets that meet marine standards and undergoing strict factory re-inspection; Utilizes multi-directional forging and temperature-controlled forging technology to refine grains and eliminate looseness; Equipped with a dedicated heat treatment system to help match hardness and toughness; Through fine sawing and shot blasting, the allowance is reduced and surface quality is improved. The final delivered shaft forgings maintain a flaw detection pass rate of over 99.5%, with dimensional tolerances controlled within ±0.5mm, helping customers achieve increased production and efficiency improvements.
