    • An installation for rolling a flat product, comprising a support stand composed of two spaced uprights between which is placed a plurality of superposed rolls, between which a squeezing force is applied, for rolling a product (B) passing between two work rolls (A, A'). At least one of the work rolls (A) consists of a tubular jacket mounted for rotation about a stationary central shaft along which is provided a plurality of spaced bushes, isolated from one another. The work roll is associated with a feed circuit for circulating pressurized oil in order to form an oil film between each bush and the jacket. The pressure of the oil film between each bush and the corresponding zone of the jacket is individually adjusted for the application of radial forces of adjustable intensity per bush.

    • A device for measuring flatness defects in a strip (15), e.g., rolled metal sheets, by the use of sensors. The voltage is measured within an amplitude measuring interval smaller than the voltage variation interval after the pulse, each sensor is associated with a correction transformer (7) capable of delivering on each energizing pulse an adjustable correction voltage (U2) algebraically added to the voltage (U1) at the terminals of the secondary winding (42) of the sensor and whose value, at the instant of measurement, is determined so as to bring the measured voltage (U3) within the measurement interval of the converter.

    • At an installation comprising a roll stand having at least one roll of the variable camber type, comprising a fixed support and a casing carried by at least three jacks and rotationally movable about the support, the pressure of the fluid in each of the jacks (14), the position of the pistons of these jacks, the speed of rotation of the roll, and the flatness and thickness of the flat product are measured. The position of one of the jacks (14b) is controlled by the thickness measurement. The pressure in the other jacks (14a, 14c, 14d, 14e) is controlled by the pressure in the one jack (14b). The positions of the end jacks (14a and 14e) are compared and the pressure in the jacks (14) is modified in order to bring the tilt of the roll to a suitable value. The deformation of the fixed support is calculated and the shape of the generatrix of contact of the roll is determined. The pressure in the jacks (14) is modified in order to bring the generatrix to a reference shape. The invention is particularly applicable to four-high rolling mills having variable camber supporting rolls.
    • 在包括具有至少一个可变弧形辊的辊架的装置中,包括固定支撑件和由至少三个插座承载并且围绕支撑件可旋转地移动的壳体,每个插座(14)中的流体的压力 ),测量这些千斤顶的活塞的位置,辊的旋转速度以及扁平产品的平坦度和厚度。 其中一个插座(14b)的位置由厚度测量来控制。 其他千斤顶(14a,14c,14d,14e)中的压力由一个千斤顶(14b)中的压力控制。 比较末端插座(14a和14e)的位置,改变插座(14)中的压力,以使卷筒的倾斜度达到合适的值。 计算固定支架的变形,确定轧辊接触母线的形状。 插座(14)中的压力被修改以便将母线引导到参考形状。 本发明特别适用于具有可变外倾支撑辊的四辊轧机。
