精轧前连续式回转飞剪的改造
摘要
精轧飞剪是线材生产工艺线上的关键设备，其功能是对轧件进行切头、切尾或事故碎断，以保证轧制工艺的畅通，减少堵钢工艺事故，提高产品质量。
近几年来，高速线材生产线上一般采用了启停式飞剪。攀钢线材厂是八十年代投产的连续式回转飞剪，这种形式的飞剪已不能满足1999年设备大修技改后的工艺要求。
为此，提出利用原来的连续式飞剪改为启停式的改造方案。即保留连续式飞剪齿轮传动的本体部分，增加一台中间减速机，重新选择直流电机，将继电器的模拟控制系统改造为计算机控制的数字系统。
该项目从一九九九年九月投产后，经过半年多的生产验证，其运行的可靠性和剪切精度均达到了国内同类引进飞剪的技术水平。
本篇论文较系统地论述了启停式飞剪设计的理论基础。详细地论述了启停式飞剪传动系统的特点及齿轮设计方法、飞剪剪切速度的确定、电机的选择与校核、启停式飞剪控制原理及位置控制原理和数学模型的建立。
本篇论文的主导思想是来源于生产实际，从企业的目的出发，用最少的投资，最短的改造周期，实现了连续式飞剪的改造，解决了制约生产发展的难题。为我国采用连续式飞剪作业的线材生产厂家提供了一种既能提高飞剪使用性能又能节省工程投资的新思路。
Finish rolling shear is the key equipment of wire rods producing 1ine, while cuts
head and end of rolled piece, so that the rolling line is smooth, and the quality of
produCts is imProved.
Recently high-speed wire rod line adopts stat-stop shear But Pan Gang wire rods
plani makes use of coniinuous tUndng round shear,ths doesn't meet process demands
after refOrm in l999.
Therefore the refOrm was suggested that changed the contnuous shear into the
sted-stop shear That is, rctaining the gear driving of the continuous sheap and adding to
a middle reduction device, and choosing a direct currCni motor again, and tdeng the
place of the relay analogUe coin1ling system for the comPuter controlling digital
system.
This project was taken in 9.l999, Through practice about a half year it showed
that it's reliabilities and precision caxne uP to inirmational technology level.
Ths paPer system intrOduce the general principles of stat-stop shear It is
described that the speeds of starstop shear to the drive .the choice of the motof,the
principles of the sted-stop shear's cothelling, the theory of site-colltrOlling, and the
constrUction of mathematics-model.
This paPer's main idea comes frOm the practice. We realize the reform of
contnuous shear and resolve the problems of the producing development on conditions
of using the 1east invesAnent and the shortest time. Ths paPer Provides a new idea of
improving shear's ability and reducing the investrnent of project.
