1.概述 随着生产技术的高速发展,生产过程中对细丝线材直径的在线测量及反馈控制的要求越来越高,越来越迫切。线径是线材的重要质量指标之一,然而,到目前为止,仍然缺乏实用方便的细丝线径的实时在线测量手段,只能在生产后进行检测,当然,这无法达到反馈控制的目的。
1. Overview With the rapid development of production technology, the demand for on-line measurement and feedback control of the diameter of the filament wire in the production process is getting higher and higher and more and more urgent. Wire diameter is one of the important quality indicators of wire. However, so far, there is still a lack of practical and convenient real-time on-line measurement of wire diameter, which can only be tested after production. Of course, this can not achieve the purpose of feedback control.
