Shanxi Jianing Forging provides customized processing of lightweight aluminum alloy forgings and aluminum flanges. The on-site aluminum alloy forging project cases are complete, with products that are lightweight and meet strength standards, compatible with new energy and lightweight equipment.
In the field of wind power equipment manufacturing, the performance of key components directly affects the safety and efficiency of the entire turbine's operation. A wind power equipment factory in Anshan, Liaoning (hereinafter referred to as the client) faced multiple technical challenges when purchasing core forgings. After multiple rounds of rigorous screening and testing, they ultimately chose the alloy steel forging solution provided by Jianing Forging, achieving simultaneous improvements in overall assembly efficiency and product reliability.
The main party involved in this cooperation is a wind power equipment manufacturer in Anshan, Liaoning, whose wind turbines have extremely high requirements for strength, toughness, and fatigue life of forgings at key connection points. Based on the technical specifications provided by the customer, Jianing Forging has custom-developed an alloy steel forging product for use at the connection between the fan spindle and the gearbox, helping to ensure continuous operation under high wind loads, low temperatures, and corrosive environments.
In the early stages of the project, the client mainly faced the following three pain points:
1. The forgings provided by existing suppliers fluctuate significantly in low-temperature impact toughness, making it difficult to meet the extreme winter low-temperature conditions (-40°C) required in Northeast China;
2. Slight looseness and inclusions inside the forging, resulting in a low pass rate for flaw detection after machining, increasing rework and scrap costs;
3. Unstable delivery times; some batch orders have dimensional deviations due to lax forging process control, affecting assembly progress and on-site commissioning scheduling.
Jianing Forging combines customers' technical indicators and working conditions to comprehensively optimize raw material control, forging process optimization, and finished product inspection:
· Selecting high-quality alloy steel materials, with precise composition control and external refining, reduces non-metallic inclusions and improves material uniformity from the source;
· By adopting multi-directional forging and temperature-controlled forging processes, the grain structure is refined, ensuring that the impact energy at -40°C is stably above the industry standard lower limit;
· Supplemented by ultrasonic flaw detection and magnetic particle inspection, the internal defect rate of each forging is kept below 0.5%, while the delivery schedule is strictly locked within the contractually agreed scope.
After multiple batches of continuous supply verification, customers reported that the forging processing yield rate exceeded 99%, with no rework issues caused by forging quality at the installation site, and the entire machine bench test passed in one go. This case has become an important reference for Jianing Forging Services in the wind power equipment industry.
