Yuezhong Industry Sharing: How did the loader shovel tooth R&D team create the "steel pioneer"? Uncover the birth process of the ingenious work

Behind a loader shovel tooth with excellent performance is the research and innovation of the R&D team for countless days and nights. So, how did the loader shovel tooth R&D team break through the technical bottleneck and create a "steel pioneer" that can cope with complex working conditions? Let us take a deeper look at the birth process of its ingenious work.

​

At the beginning of the R&D work, the team faced huge challenges. When facing extreme working conditions, traditional shovel teeth either have insufficient hardness, causing excessive wear, or poor toughness and easy fracture. To solve this problem, the team members plunged into the laboratory and conducted repeated proportioning tests on dozens of alloy materials on the market. They tried to incorporate different proportions of alloy elements such as chromium, molybdenum, and vanadium into steel, and tested the hardness, toughness and other performance indicators of the material by changing the heat treatment temperature and time. After nearly a hundred failures and adjustments, a new high-chromium alloy formula was finally developed, with a hardness of more than HRC60 and impact toughness far exceeding the industry standard. ​

After the material problem was solved, the structural design of the shovel tooth was also full of challenges. How to improve the cutting efficiency and reduce the resistance of the shovel teeth while ensuring the strength is the focus of the team. Engineers used computer simulation technology to simulate the stress of different tooth shapes in various materials. After thousands of parameter adjustments and optimizations, they finally determined a tooth shape design with a unique arc and cutting angle. This design not only improves the efficiency of the shovel teeth cutting into the material by about 30%, but also effectively disperses stress and reduces the risk of fracture. ​

To verify the research and development results, the team went deep into construction sites such as mines and ports many times to collect actual operation data. In a field test in a mine, the prototype shovel teeth showed partial cracking. The team quickly organized technical backbones to analyze and found that it was caused by stress concentration. They modified the design overnight and successfully solved the problem by adding transition fillets and optimizing the tooth root structure. After repeated testing and improvement for half a year, a stable and reliable loader shovel tooth was finally created. ​

Throughout the research and development process, the team members always adhered to the attitude of excellence and did not miss any details. It is this persistent pursuit of quality and the spirit of innovation that has enabled them to successfully overcome numerous technical difficulties, bring a revolutionary product to the loader shovel tooth industry, and become the "steel pioneer" in engineering operations.

The birth of this loader shovel tooth is the result of the R&D team's sweat and wisdom. From hundreds of tests on material formulas, to thousands of optimizations of tooth shape design, to repeated polishing of field tests, every step embodies the pursuit of ultimate performance. It is this spirit of innovation and the attitude of craftsmen who strive for excellence that allows the "steel pioneer" to break through technical barriers and demonstrate outstanding strength in complex working conditions. It not only redefines the performance standards of loader shovel teeth, but also demonstrates the strength of China's engineering machinery field in core technologies, injecting strong momentum into the high-quality development of the industry.
