管道输送是矿井、油田、乃至城市建设中都广泛采用的一种技术装置。山东邹县正处于兖州矿区与胜利油田之间,所以钢管法兰是该地区需求量极大的工业产品之一。以往多采用铸造和平板切割两种制坯工艺。然而制件质量和成本都未能使用户满意。在山东省济宁市和邹县县委的支持下,决定引进哈尔滨工业大学研究成功的液态模锻工艺生产钢质平焊法兰。济宁市科委已正式列为1986年度科研课题并于
Pipeline transportation is a technical device that is widely used in mines, oil fields and even urban construction. Zouxian in Shandong is between Yanzhou Mining Area and Shengli Oilfield, so the steel pipe flange is one of the industrial products in great demand in this area. In the past more than two kinds of casting and flat cutting billet process. However, the quality and cost of the parts failed to satisfy the customers. With the support of Jining City, Shandong Province and Zouxian County Committee, it was decided to introduce the liquid die forging process successfully researched by Harbin Institute of Technology to produce steel flat welding flanges. Jining Municipal Science and Technology Commission has officially listed as 1986 annual research project at
