水平辊式矫直机的矫直辊的速度调控方法和系统
摘要：
本发明公开了一种水平辊式矫直机的矫直辊的速度调控方法，对n号矫直辊的速度调控方法包括以下步骤：（a）确定钢轨的矫直线速度Vz；（b）按照速度调控公式对n号矫直辊进行控制；其中：当n号矫直辊为与钢轨接触的沿矫直方向的第一个或最后一个矫直辊时，速度调控公式为Vjn=VZ(1+P1n)，Vjn和P1n分别为n号矫直辊的表面线速度和第一机器修正值；当n号矫直辊为除与钢轨接触的沿矫直方向的第一个或最后一个矫直辊外的其余的矫直辊时，速度调控公式为 Vjn为n号矫直辊的表面线速度，L为矫直机的节距、Tn为钢轨和n号矫直辊的接触点与钢轨的中性层的垂直距离、P’1n为n号矫直辊的第二机器修正值，Δhn为n号矫直辊的修正压下量，b2为第二系数。
摘要（英）：

The invention discloses a method for adjusting and controlling speed of a strengthening roll of a horizontal roll type straightening machine. The method for adjusting and controlling the speed of the number n straightening roll includes the following steps: (a), determining the speed Vz of a straightening line of a steel track; and (b), controlling the number n straightening roll according to a speed adjusting and controlling formula. When the number n straightening roll is the first or the last straightening roll contacting the steel track along the straightening direction, a speed adjusting and controlling formula is Vjn=VZ(1+P1n), and Vjn and P1n are surface linear velocity and a first machine revision value of the number n straightening roll respectively; and when the number n straightening roll is one of the rest straightening rolls apart from the first or the last straightening roll contacting the steel track along the straightening direction, the speed adjusting and controlling formula is as follows, wherein Vjn is the surface linear velocity of the number n straightening roll, L is a pitch of the straightening machine, Tn is the vertical distance between a contact point of the steel track and the straightening roll and a middle layer neutral layer of the steel track, P'1n is a second machine revision value of the number n straightening roll, delta hn is revision rolling reduction of the number n straightening roll, and b2 is a second coefficient.
