    時間常數指數
  2. The unfavorable factors contain complicated production technology and wayward product quality, etc. first of all, on the basis of analyzing performance index of 3 - layer pe anticorrosion, technological process and operational environment, this paper advances the synthetic control schemes that have constant compound control of temperature and feedback control of speed. considering the production process of the 3 - layer pe, because it is affected by colloidized time of fbe, relatively strong coupling exists between the temperature and speed. through the rational matching and simplifying of the variable, the system realizes uncoupling

    首先在分析三層pe防腐層性能指標、工藝過程及工況條件的基礎上,提出了溫度復合控制和速度反饋控制的綜合控制方案;考慮到三層pe生產過程中,由於受fbe膠化曲線的影響,溫度和速度之間存在較強的耦合,本方案通過合理的變量搭配,實現兩種變量的解耦;文中還依據傳熱理論、中頻感應理論等提出鋼管傳熱過程理論建模的方法,經實際驗證,表現出該方案和建模方法的科學性和實用性。
