摘要
对钢轨进行全长欠速淬火是提高其使用寿命的主要途径。为了保证淬火钢轨质量的稳定,提高淬火钢轨的一级品率和成品率,设计出钢轨全长欠速淬火模糊控制系统,对钢轨淬火过程进行自动控制。该控制器综合了模糊控制和PID控制的优点,具有超调小,响应快,鲁棒性强等特点。应用结果表明,该控制器使得淬火钢轨的一级品率与成材率大大提高,具有推广应用价值。
Slack quenching is a main way to prolong the lifespan of rail.To ensure the quality stability of quenched rail and improve ratio of first-grade products and product rate of quenched rail,a fuzzy control system for full-length quenching technology was designed,which automatically controls the process of rail quenching.This controller combines the advantages of the fuzzy control and PID control,which possess such features as small overshoot,fast response,robust etc.The application result indicates that this controller makes a great improve of ratio of first-grade products and product rate of quenched rail,therefore it is worthy of popularization and application.
