摘要： The invention relates to electronic control of a crop shear for trimming the head and tail of a bar. The bar is scanned longitudinally by a camera to monitor its progress towards the crop shear. The bar is also scanned transversely by a second camera connected to a processor which analyses the shape of the bar to determine the optimum point for cropping. The method is also described for distinguishing between the outline of a bar and surface anomalies such as may be caused by water or scale on the bar.

摘要： A rolling mill system for the continuous rolling of metal strip or strand into a strip of predetermined thickness and straightness is disclosed. The system includes a frame in which two metal working rolls are mounted in such a way that both the distance or nip between the rolls and the tilt of one roll with respect to the other may be regulated by two gap adjusting devices mounted in the roll frame on opposite sides of the centerline of the metal strip. At least one of the gap adjusting devices is operated responsive to a signal representing a measurement of the straightness of the strip product. The gap adjusting devices are hydraulic assemblies wherein each piston is affixed to a piston rod and each piston rod is affixed at its opposite end to a chock block in which the movable roll is carried. A position indicating rod which constitutes part of a position transducer is affixed to the opposite face of each piston to allow for monitoring of the actual distance between the two rolls at each end thereof. The motor drive from one roll is mounted on a door forming part of the roll mill frame to allow for free access to the rolls and chocks. The straightness or camber of the strip product is monitored and the tilt of the movable roll with respect to the other roll is controlled responsive to signals representative of variations in camber.

摘要： In a rolling mill containing two work rolls and, as desired, supporting or back-up rolls, a rapid adjustment of the roll gap or nip with elimination of effects due to elastic elongation of the roll framework or stand is achieved in that when structuring at least one of the rolls as a controlled deflection roll containing a stationary roll support and a rotatable roll shell rotating thereabout, there is measured the position of the inner side or surface of the roll shell and an automatic control serves to adjust or readjust the roll gap or nip by causing changes in the pressure exerted upon the hydrostatic supporting or pressure elements placed intermediate the stationary roll support and the rotatable roll shell.

摘要： A transport apparatus comprising a plurality of metal rolls for transporting a hot heavy material is disclosed. Each roll is provided with a desired number of ring-like circumferential grooves which are filled with a heat insulating material, and the grooves of each roll are staggered with respect to the grooves of the adjacent rolls. In accordance with the present invention, the temperature drop of the hot heavy material during the transportation can be greatly reduced, and in addition, the temperature fluctuation in both the sectional direction and the longitudinal direction of the hot heavy material is sharply decreased. The invention contributes considerably to the realization of the direct rolling process on an industrial scale.

摘要： A combination for accurately determining the position of the movable part of a piston-cylinder device relative to the fixed part includes a long stroke position transducer movable in the operating direction of the device; a structure movable with the piston-cylinder device and which has a part extending in the operating direction; two position transducers positioned side-by-side and their direction of movement is normal to the operating direction. The movable parts of the two position transducers bear against the part of the structure. If there is no tilting of the piston within the cylinder, then electrical signals from the two position transducers remain unchanged, but the signals are changed if the piston tilts within the cylinder.

摘要： In a tandem rolling mill a control computer integrates the entry speed of a work strip having a gauge transition to determine the arrival of the transition at a first roll stand. At that time a screw-down on that stand is updated through a scheduling computer while roll speeds on all the stands remain unchanged. When the gauge transition arrives at each of the succeeding stands as determined by the control computer integrating a roll speed on the preceding stand, the scheduling computer updates a screw-down on the arrival stand and changes roll speeds so as to minimize the sum of the squares of changes in roll speed with the constant mass flow relationship fulfilled.

摘要： A draw control system for a process line is provided wherein the process line comprises a number of stand or sections having the speeds N.sub.1, N.sub.2 -N.sub.n. The stands are provided with a master reference voltage V which may be modified at each section to change its speed to N.sub.n +.DELTA.N.sub.n where n=1-2, 3-n. One section is selected as a no-draw section, i.e., the master voltage is applied without change to the speed regulator for that section to determine its speed, say N.sub.1. All succeeding sections comprise non-inverting summation operational amplifiers arranged in cascade respectively so that the output of one determines the speed for its section and this output is also applied to the input of the non-inverting summation amplifier for the succeeding section. With this arrangement all perturbations ripple on through the draw control system so that interstand tension is maintained under all conditions. Thus, if the master reference voltage is changed to V+.DELTA.V then ##EQU1## and if N.sub.n-2 is changed to N.sub.n-2 +.DELTA.N.sub.n-2 in order to increase the interstand tension between stands N.sub.n-2 and N.sub.n-1 then the speed N.sub.n is changed to .DELTA.N.sub.n +.DELTA..sub.n and .DELTA.N.sub.n =.DELTA.N.sub.n-1 .The input to the each cascaded non-inverting summation operational amplifier includes a scale factor or multiplier K which sets the range for the change in speed for each section respectively.
摘要翻译：提供了一种用于生产线的拉丝控制系统，其中该加工线包括多个具有速度N1，N2-Nn的支架或部分。支架具有主参考电压V，其可以在每个部分处修改以将其速度改变为Nn + DELTA Nn，其中n = 1-2,3-n。选择一个部分作为无牵引部分，即，将主电压施加到该部分的速度调节器以确定其速度，例如N1。所有后续部分包括分别布置成级联的非反相求和运算放大器，使得一个的输出决定其部分的速度，并且该输出也被施加到用于后续部分的非反相求和放大器的输入。通过这种安排，所有扰动通过牵引控制系统产生波动，从而在所有条件下保持架间张力。因此，如果主参考电压变为V + DELTA V，则，并且如果Nn-2变为Nn-2 + DELTA Nn-2，以便增加机架Nn-2和Nn-1之间的架间张力，则速度Nn改为DELTA Nn + DELTA n，DELTA Nn = DELTA Nn-1。每个级联的非反相求和运算放大器的输入包括比例因子或乘法器K，其分别为每个段设置速度变化的范围。
