    摘要： Cooling equipment for supplying jets of cooling liquid in laminar form comprises a horizontal header and a plurality of nozzles each of which is removably located in openings in the top and bottom of the header. The nozzles are sealed in the header to prevent leakage and to ensure that water in the header issues through the nozzles.

    摘要： An ingot manipulator for use with a rolling mill has a pair of elongate manipulator heads arranged on opposite sides of a roller table on the entry side of the mill, the heads being displaceable transverse to their length towards and away from each other and one of the heads has on the side thereof facing the other head a plurality of tilting fingers, the fingers are arranged in at least two groups positioned side-by-side on the head and drive means are provided for operating fingers to tilt ingots arranged in tandem on the roller table. Means are also provided by which the fingers of one group are operable independently of the fingers of the other group or groups so that if all the fingers are initially operated together to tilt two or more ingots and one ingot fails to tilt then the group of fingers associated with that ingot can be operated independently of the other fingers to bring about tilting of that ingot.

    摘要： AN EXTRUSION PRESS HAS ITS DIE SUPPORTED IN A HOLDER WHICH IS RELEASABLY COUPLED TO AN ANCHOR MEMBER TO FORM AN ASSEMBLY. THE ASSEMBLY IS DISPLACEABLE RELATIVE TO THE PLATEN IN A DIRECTION NORMAL TO THE LONGITUDINAL AXIS OF THE PRESS AND IN ORDER TO REMOVE THE DIE AND ITS HOLDER, THE ASSEMBLY IS SLID ACROSS THE FACE OF THE PLATEN UNTIL THE HOLDER IS IN A POSITION FROM WHICH IT CAB BE DISPLACED PARALLEL TO THE AXIS OF THE PRESS TO RELEASE THE DIE HOLDER FROM THE ANCHOR MEMBER. DISPLACEMENT OF THE DIE HOLDER PARALLEL TO THE AXIS OF THE PRESS CAN CAUSE A REPLACEMENT DIE HOLDER TO BE DISPLACED INTO COUPLED RELATION WITH THE ANCHOR MEMBER.

    摘要： 1,127,926. Automatic control of rolling. DAVY & UNITED ENG. CO. Ltd. Dec. 15, 1965 [Dec. 22, 1964], No. 52116/64. Heading G3R. [Also in Division B3] In a rolling mill, parts of the mill other than the rolls are pre-stressed to an extent that is automatically controlled by a signal derived from independent measurements of the pre-stressing load and the total of the pre-stressing load and the rolling load, so that the roll gap is maintained constant. In Fig. 1, mill rolls 20 are journalled in chocks 17, 18 located in recesses in further chocks 14, 15 carrying back-up rolls 16. Chocks 14, 15 are located in end housings 12 and the roll gap is adjustable by screws 22. The mill stand is pre-stressed by hydraulic actuators 25 which force chocks 14,15 apart and are under the control of a valve 27. When material is being rolled, an electrical signal dependent on the total force is derived from load cells 23 associated with screws 22 and another signal dependent on the pre-stressing force is derived from a pressure transducer 29 associated with the hydraulic supply to actuators 25. The difference between these two signals, which represents the rolling force, is obtained by a circuit 31. A proportion of this rolling force signal is selected by a potentiometer 32 and added to the total force signal by a circuit 30 to produce a signal representative of the enlargement of the roll gap caused by the forces involved. This calculated gap enlargement signal is compared with a desired enlargement signal obtained by subtracting, in a circuit 41, a signal from a transducer 40, representing screw-down setting, from an adjustable reference signal produced by a unit 35. Any difference resulting from the comparison produces an output from a circuit 33 which is applied to control valve 27 so that gap enlargement is restored to the desired value. Signals from a gauge 38 detecting errors in thickness of the rolled material are integrated at 37 and modify the output of unit 35 to correct long term changes in thickness. Camber of the rolls may be automatically controlled by the signal representing rolling force to maintain a desired shape of cross-section. Alternative arrangements for pre-stressing the mill and for calculating the gap enlargement are referred to.
