计算机辅助螺纹钢孔型设计系统的开发及应用

Development and Application of Computer Aided Roll Design System for Thread-steel-bar

型钢孔型设计是制定型钢轧制工艺的重要内容之一.传统孔型设计过程以人工经验为主,其计算繁琐,原材料消耗大.为提高生产效率,通过对螺纹钢延伸孔型系统、精轧孔型系统及成品孔型的构成和设计方法的分析,结合螺纹钢孔型系统的基本设计理论和实际生产经验,对以往孔型设计过程中所使用的数学模型、经验公式等进行了修正,并以结构化程序设计方法为基础,采用可视化编程工具V isual Basic6.0建立了计算机辅助螺纹钢孔型设计系统.试用效果表明,缩短了新产品的设计周期,降低了轧机能耗和生产成本.

Roll pass design is one of the important content of making the rolling technology of section steel. The traditional pass design relies mainly on artificial experience, which brings some tedious calculation and great consumption of raw materials. In order to improve production efficiency, the constitute and the design methods of the roll system for thread-steel-bar are analyzed during stretching, further rolling and finished rolling. The mathematical models and the experience formulas used for the roll design in the past are revised. The computer aided roll design system is developed for thread-steel-bar based on the structural means of compiling program. The authors adopt Visual Basic6.0 as a visual program tool, and combine the basic design theory of the thread-steel-bar＇ s roll and the practical experience. The system can shorten the design cycle of the new product development, and reduce the energy consumption of the rolling mill and the distribution of production.
