702 Institute, China Shipbuilding Industry Corp. Set Titanium Casting Records 中船重工七二五所钛合金铸件创四项纪录
Shuangrui Precision Titanium Casting Co., owned by the 702 Institute, which is affiliated with the China Shipbuilding Industry Corp., Beijing, China, produced a large cast titanium main frame for an aerospace project on Nov. 30, 2011. Te casting set records for being the heaviest, largest, thinnest and most complicated titanium casting produced in China. It was reported the casting was designed by Chinese
Aerospace Science & Technology Corp. Shuangrui Precision Titanium won the order due to its unique and large equip- ment, machining precision, high technology and production capability. A special team was formed at the company for the development of the product. Te team improved the design, performed specimen tests, and made breakthroughs in design, patternmaking, precision and dimensional control, among other areas. Te innovative patternmaking and melting and pouring parameters were required to produce the 400-metric ton casting with walls as thin as several millimeters. ■
2011年11月30日，中船重工七二五所双瑞精铸钛业 公司（简称双瑞精铸）为航天某重点型号研制的超大钛 合金铸件――主承力框，一次浇铸成功。该铸件在我国钛 合金铸造一次成型产品中创下重量最大、尺寸最大、整 体壁厚最薄、结构最复杂四项纪录。
据介绍， 该铸件经航天科技集团所属单位设计完成 后，双瑞精铸凭借设备能力国内最大，以及模具加工精 度高、工艺设计水平精湛、生产能力过硬等优势获得研 制合同。其专项研制攻关小组，经多次局部结构模拟体 的设计、浇注、优化试验，相继突破了大型复杂薄壁钛 合金铸件的工艺设计、模型制造、浇注成型、尺寸精度 控制等关键技术难题；并改变传统方式创新模型制作， 最终确定熔炼及浇注工艺参数，确保了400多公斤重， 整体壁厚仅几毫米的精度要求。■

Dongfeng-Nissan Plant in Zhengzhou, China, to Increase Need for Aluminum Castings
东风日产郑州厂奠基 带动铸造用铝需求
Carmaker Nissan recently established the Dongfeng Nis- san Zhengzhou Engine Plant in the Zhengzhou Economic Development Zone of China. When the plant is finished, its production capacity will be 450,000 cars, which will drive the need of aluminum castings. Dongfeng Nissan currently produces engines for its Chinese
products in Huadu, Guangzhou. Te expansion of Dongfeng Nissan into Zhengzhou will help it achieve its goal of more than 1.3 million units and become a top-three Chinese auto- motive company by 2015. It is estimated the facility will need more than 4,000 metric tons of aluminum components. Some aluminum recycling companies are planning to construct facili- ties in Zhengzhou to supply material to Dongfeng Nissan. ■
近期，东风日产郑州发动机工厂在郑州经济开发区 举行项目奠基仪式，项目建成后，将形成60万台发动 机、45万辆整车的生产规模，将极大促进华中地区铸造 铝合金的消费。
目前东风日产的国内发动机生产主要集中在广东花 都，而此次郑州工厂的扩建也是其为实现2015年销量超 过130万、市场占有率进入行业前三的目标迈出坚实的 一步，更是东方日产加大华中市场布局的重要举措。据 析，郑州发动机新厂全面投产后，每月铸造铝合金需求 将超过4,000t，这也极大促进当地的消费。目前国内一 些大型再生铝企业也正策划在郑州建设工厂，为东风日 产直接供应铝液。■
