在计算机控制热轧带钢的生产中,为使带钢顺利通过轧制线,获得具有一定尺寸精度、良好板型和具有一定机械性能的成品、确保整个轧制线上设备的安全运行,必须建立一套完整的能被计算机所应用的数学模型。轧制压力数学模型对精轧机组辊缝设定至关重要,它决定着轧制过程的正常进行和成品带材的尺寸精度。 武钢1700热连轧厂是全套从日本引进具有七十年代水平的计算机控制的生产,所采用的控制模型均属日本专利。几年来的生产实践表明,日本所提供的精轧轧制压力模型
In the production of computer-controlled hot-rolled steel strip, in order to pass the strip smoothly through the rolling line, to obtain a certain size precision, good plate and have certain mechanical properties of the finished product to ensure the safe operation of the equipment on the rolling line must Establish a complete set of mathematical models that can be used by computers. The mathematical model of the rolling pressure is crucial for the setting of the roll gap in the finishing mill. It determines the normal rolling process and the dimensional accuracy of the finished strip. Wuhan Iron and Steel 1700 hot rolling plant is a full set of imported from Japan with the seventies level of computer-controlled production, the control model used are Japanese patents. Years of production practice shows that the Japanese supply of finishing rolling pressure model
