摘要： PURPOSE:To permit changing of sheet gauge sizes with good accuracy in a tandem rolling mill by making the start point and end point for charging the target tension of a stand coincident respectively with the start point and end point of changing the size when the start point for changing the size arrives at a control system for specifying the tension behind said stand. CONSTITUTION:Work rolls 2-5 are driven by electric motors 6-9, and a material 1 to be rolled is rolled. The speeds of the motors are controlled with control systems 10-13, and the tensions on the material 1 between the stands are measured with tension meters 18-20, which tensions are transmitted with control systems 21-23 for specifying tension to rolling down control systems for moving the rolls upward and downward. When the start point for changing the sheet gauge size of the material 1 passes the (j)-th stand, the target value Tj-1 of the tension between the (j-1)-th stand and the (j)-th stand is derived from the prescribed equation, and the result thereof is transmitted to the control systems 21-23 for specifying the tension between the (j-1)-th stand and the (j)-th stand. The control is thus accomplished until the (j) attains the total number N of the stands.

摘要： PURPOSE:To improve the accuracies of the length and thickness of an off-gauge part, by changing the sheet thickness at the top and bottom parts of a coil during rolling, and performing the rolling by combining a schedule calculation for obtaining the target sheet thickness and an AGC in absolute value of a whole stand. CONSTITUTION:The length of an outer peripheral portion of one turn is calculated by turns of rolled coils by inputting a coil information about the thickness, the width, the weight, and the coil thickness, etc. of a sheet to be rolled, and the result is used as the target off-gauge length. The off-gauge length is used in calculation as the length at the inlet side of one stand, and is used for a changing point of the sheet thickness during rolling. For changing the sheet thickness in actual rolling, a rolling draft, the number of revolutions, an AGC in absolute value are set up and a change of setting of a thickness gauge is performed by tracking the changing point of the sheet thickness during rolling. In a case when a sheet is free from tension at the front or rear side of each stand by the condition of biting or passing through of the sheet resulting from passing or run-out of the sheet at said stand, a schedule calculation is performed so as to obtain the target sheet thickness. Two kinis of the target sheet thickness at the middle and the off-gauge parts may be required.
摘要翻译：目的：通过改变轧制过程中线圈顶部和底部的板厚度，通过组合用于获得目标板厚度的进度计算来进行轧制，提高不规则部件的长度和厚度的准确性和一个整体平台的绝对值的AGC。构成：通过输入关于被轧制片材的厚度，宽度，重量和线圈厚度等的线圈信息，通过卷取的线圈的匝数来计算一圈的外周部的长度，结果用作目标超标长度。计算中使用的不合格长度作为一个支架入口侧的长度，用于轧制时板材厚度的变化点。为了实际轧制中的板厚变化，设定轧制牵伸，转速，绝对值的AGC，并且通过跟踪轧制时的板厚变化点来进行厚度计的设定变化。在通过在所述台架上由片材的通过或流出而导致的片材的咬合或通过的情况下片材在每个支架的正面或背面处没有张力的情况下，进行计划计算以获得目标片材厚度。可能需要在中间的目标片材厚度和不合格的部件的两个激光。

摘要： PURPOSE:To make use of the heat retained in a strip after hot rolling and to economize the consumption of driving power for cold rolling by subjecting said strip in a high temp. state to mechanical descaling then cooling the same to a proper temp. and cold rolling the cooled strip. CONSTITUTION:A strip which is uncoiled from a hot rolled coil 1 of a high temp. is passed through a rolling mill 2 of light rolling down to fine coil break and is then conducted to a mechanical descaling device 3, where the strip is descaled by blasting of a slurry contg. sand iron in the state of the high temp. The strip is conducted into a temp. controller 4 where the strip is cooled down to the temp. optimum for cold rolling and is then passed through a cold rolling mill 5. The temp. of the strip to be passed through the mill 5 is selected within the temp. range of about 50-250 deg.C and at the temp. at which the rolling load is least according to the steel kind of the strip. The heat is recovered through the salt bath or rolling mill oil or the like used in said controller 3, whereby the energy is economized additionally.
