Problems solved by technology

[0002] The crane wheel is not only an important bearing part but also a key running part. Its quality determines whether the crane can work safely and reliably. It affects the working efficiency of the crane and affects the service life and life of the crane. In addition, there are many parts. At least 8 sets of cranes are required, so the impact is relatively large. At present, foreign crane wheels are mainly made of ductile iron, which is mainly formed by casting technology; domestic crane wheels are mainly made of cast steel, which is mainly formed by casting technology. Smaller wheels with a relatively simple structure are manufactured using traditional forging processes, which have problems such as large consumption of raw materials, large follow-up processing, and harsh manufacturing environments; in addition to the above-mentioned defects, traditional casting processes also have There are many internal defects, non-compact structure, low strength, etc. Therefore, it is of great significance to develop a crane single-girder travel wheel forging process with high quality, low energy consumption, low material loss, and high production efficiency.
