On October 28, 2023, ZGYZ Heavy Machinery Technology Corporation successfully delivered the lower anvil and Backing ring manufactured for the 3500KJ hydraulic piling hammer!
The lower anvil and Backing ring are the largest offshore forging products developed by ZGYZ, with a Backing ring diameter of 8.88 meters and a lower anvil diameter of 7.68 meters.
The diameter of the anvil and backing ring is extremely large and the cross-section is complex, which belongs to the category of extreme manufacturing.
ZGYZ and ZJ forging technology research and development institutions jointly formed a joint research and development team, proposing the use of original forming processes and independently developed external forging technology to solve the deformation problem during the heating process of ultra large cylinder billets. At the same time, existing equipment was fully utilized and combined with new technologies and processes to achieve profile forging of irregular forgings, ensuring the successful forging of the lower anvil seat and Backing ring.
The successful manufacturing of the core forging of the 3500KJ hydraulic pile hammer marks a significant milestone in the original technology of ZGYZ large forgings, breaking technical barriers in the field of core material manufacturing for offshore equipment.
On November 21, 2020, The weight of 165 tons with diameter 7.6 meters backing Ring for the 3500 kilojoule large marine hydraulic piling hammer developed by SDYL Energy Equipment Technology Corporation, successfully rolled backing ring forging, breaking the bottleneck of a diameter of 7.5 meters and breaking the record for the largest size of similar components in China, marking China's leading international manufacturing technology for oversized irregular ring forgings.
In 2019, the successful development of China's first 2500 kilojoule hydraulic piling hammer with fully independent intellectual property rights broke the long-standing technical and market monopoly of foreign countries on hydraulic piling hammers for large-scale offshore operations.
In the future, the 3500KJ hydraulic piling Hammer will further enhance China's ability and position in marine industry equipment manufacturing, laying a solid foundation for the rapid development of China's marine resource development!
