摘要
X-H轧制法是一种先进的H型钢轧制工艺。它是在三机架可逆连轧机
    组上实现,第一架万能轧机的立辊为腰鼓形,第二架万能轧机的立辊为圆柱
    形,可直接轧出成品。这样的布置形式,大大缩短了厂房的长度,减少了投
    资,给H型钢的生产厂家带来了很大经济效益。
     由于在X—H轧制法中第一架万能轧机的立辊为腰鼓形,在轧制H型钢
    时立辊锥角的大小直接影响力能参数和H型钢翼缘的宽展,为了给出X—H
    轧制法中合适的立辊锥角,本文作者利用上限法分析了立辊锥角对力能参
    数的影响;并在腹板和翼缘的延伸率近似相等的前提下,从腹板与翼缘的
    理想速度差、侧压量以及水平辊侧面搓轧三个方面定性地分析了立辊锥角
    对H型钢翼缘宽展的影响。同时在实验室三机架可逆机组上做了大量的实
    验,在相同来料和翼缘与腹板的绝对压下量相等的前提下,改变立辊锥角
    的大小,从中分析出立辊锥角对力能参数和翼缘宽展变化的规律。从理论
    分析和实验结果可以得出:锥角增大,翼缘的宽展减小,轧制力矩减小。
     为了实现X—H轧制法的自动控制,本文作者给出了三机架连轧机组的
    程序压下和过程自动控制数学模型。经综合分析,在X-H轧制法中,立辊
    锥角取5°是合适可行的。
Abstract
     The X桯 rolling method is an advanced rolling technics in the H-beam
     production field. It is implemented in the three-stands reversible tandem rolling
     set. The vertical rollers are drum form in the first universal stand and they are
     columniform in the second universal stand, it can produce finish product. Such
     layout form can shorten the length of the workshop and reduce the investment so
     that the H-beam manufacturer can make much more profits.
    
     The vertical rollers of the first universal stand are drum form. The affection
     of vertical roll cone angle on force parameter and flange spread. To give out
     vertical roll cone angle of the X桯 method, the upper bound method is used to
     analyze the affection that the vertical roll cone angle pla~抏d on the power
     parameters. Under the precondition of approximately equation of web elongation
     and flange elongation, the affection of vertical roll cone angle on the H-Beam
     flange lateral spreading is also analyzed in three aspects: the ideal speed
     difference between web and flange, side depression and horizontal roller side
     twist rolling. Many experiments had been done on the three stands reversible
     tandem rolling set. Under the precondition of mill bar and absolute gauge
     reduction, cone angles changed. The law is given by it. From the theoretical
     analysis and experimental result, conclusion is obtained: cone angle augment,
     flange spread and rolling torque decrease.
    
     In order to realize auto-control of the X桯 method, this paper gave out the
     mathematic model about the procedure cogging and course auto-control of the
     three stands reversible tandem rolling set. Comprehensive analysis, It is suitable
     that vertical roll cone angle is 5 degree in the X桯 rolling method.
