五、线材轧机设备的展望 线材轧制的主要特点是轧件断面小,特别在精轧区,轧件直径只有φ5.5mm、φ6mm、φ6.5mm等等,它所带来的问题一是产量低,二是散热快。因此,生产中的关键问题是“快速”。要“快速”,就带来了一系列的问题。如高速轧件的扭转,控制高速运动的轧件,设计和制造高速轧机等等。要提高线材轧制工艺的水平,抓住问题的关键,首先应在精轧机上下功夫。近十多年来,高速线材精轧机有了很大的突破,轧速已达115m/s,制造精度要求很高(摩根精轧机的传动齿轮按美国AGMA标准的11级或12级质量标准制作)。高速线材精轧机虽然局
Fifth, the prospect of wire rod mill equipment Wire rolling is characterized by small rolling section, especially in the finishing area, the rolling diameter of only φ5.5mm, φ6mm, φ6.5mm and so on, it brings the first problem is the output Low, the second is fast heat dissipation. Therefore, the key issue in production is “fast.” To “fast”, it brings a series of questions. Such as high-speed rolling of the torsion, the control of high-speed rolling of the workpiece, the design and manufacture of high-speed rolling mill and so on. To improve the level of wire rod rolling process, to seize the crux of the problem, first of all should be on the finishing mill work hard. In recent ten years, high-speed wire rod finishing mill has made a great breakthrough, rolling speed has reached 115m / s, high precision manufacturing (Morgan finishing mill gear according to the United States AGMA standard 11 or 12 quality standards ). Although high-speed wire rod mill
