On August 21, a 12-meter light alloy ring rolling mill made in China was successfully rolled in one time at Hunan Zhongchuang Sky New Material Co., Ltd., breaking the world record of the maximum diameter of 10 meters for light alloy. The 12-meter light alloy super-large ring piece met the expected precision requirements, laying a solid foundation for China's new large-scale transportation and deep space exploration projects. Large-diameter and super-large-diameter light alloy rings are the core parts of the aerospace industry, related to national strategic security, and the limit manufacturing of high-quality light alloy rings restricts the development of China's aerospace transportation tools. Due to changes in the international situation, the import of core technologies is restricted, and the localization of high-end heavy-load light alloy ring rolling machines has become a bottleneck restricting the enhancement of China's aerospace transportation capacity. Ring rolling equipment has the characteristics of technology intensive, system complexity, strong driving force, reflecting the development ability of China's deep space exploration technology, which is the key to cultivate and develop strategic emerging industries and realize the dream of manufacturing a strong country.

Xinjiang Boyuan Aluminum Co., Ltd. is making every effort to advance the construction of its new-type aluminum semis project with an annual capacity of 150,000 mt. Located in the Huoshaoshan Aluminum Downstream Industrial Park of Xinjiang Zhundong Economic and Technological Development Zone, the project involves a total investment of 180 million yuan and covers an area of 64 mu. It is planned to build two standardized production workshops with a total floor area of 23,000 m². In terms of production line configuration, the project will be equipped with two aluminum rod production lines, eight cast-rolling aluminum coil and strip production lines, and one cold-rolling aluminum coil and strip production line. Once fully completed and put into operation, the project is expected to achieve an annual production capacity of 60,000 mt of aluminum wire and 90,000 mt of aluminum coil.
