Title: Continuous casting system
IPC: B22D11/16
Filed: 1969-06-19
Abstract: 1,269,563. Continuous casting machines. WESTINGHOUSE ELECTRIC CORP. 19 June,   1969 [1 July, 1968] No. 30992/69. Headings B3F and B3V. [Also in Division G3] A continuous casting system has a mould 14, a plurality of controllable devices, e.g. cooling means, pinch rolls 18 and 20 and a torch cutting machine 144, successively disposed along the casting line, a computer 10, means for generating digital position information for each increment of advance of the cast product and means for feeding said information to the computer. The computer keeps track of the position of the cast product as it progresses along the casting line and on arrival of the cast product at each of said devices the computer applies control functions to the devices in their successive order. The computer also monitors and compares against stored references conditions such as coolant and strand temperatures, coolant flow rates and pinch roll pressure; if these parameters deviate beyond acceptable limits the computer prints out an alarm. After leaving the mould 14 the cast strand passes through spray cooling zones 22, 23 and 24 each having a flow control FC and a flow meter FM, each flow control being operable to on or off in response to commands from the computer and adjustable from the operator's console to change the rate of coolant flow. The strand then passes through the computer-controlled pinch roll sets 18 and 20 the roll pressures being adjustable from the operator's console. A pulse generator PG1 generates a pulse for each increment of angular travel of the roll 88; these pulses are transmitted to the computer thus enabling it to calculate the speed and total length of the strand. The dummy bar chain 116 is detached from the strand on lowering of the straightening roll 126 and the strand passes to the torch cutting machine 148 (Fig. 3) which clamps itself on to the strand by means of tongs 228 while the torches 146 and 148 move laterally cutting towards the centre of the strand. The distances moved by the torches are communicated to the computer in the form of pulses given out by the pulse generators PG2 and PG3. After cutting of the strand is complete the tongs 128 are released and the torch machine returns to the point on the strand where the next slab cut is to begin, the distance travelled being made known to the computer by means of the pulse generator PG4. The severed slab is pulled away from the strand by speeding up the runout rolls RO1, RO2, RO3 and RO4. When casting is finished the computer shuts down the various devices in the appropriate order. The various parameters monitored by the computer are printed out on an information sheet. The operator's console 9 includes controls for entering slab width, thickness and length into the computer and for adjusting the output of tundishes TD1 and TD2, the mould oscillator control OR, the mould lubricant control LC, coolant flow rates, the pressure exerted by rolls 70 and 90 and the speed of all roll drive units.

Abstract: 484,928. Gear - cutting. BROWN, & SONS (HUDDERSFIELD), Ltd., D., and SYKES, A. Nov. 18, 1936, No. 31530. [Class 83 (iii)] The work-table of a gear-hobbing machine is driven by means of double-reduction gearing including spur or helical gearing a, b and worm gearing e, d, the gearing being carried in a cradle g which is moved tangentially or concentrically of the blank in unison with the hob carriage movement to distribute the errors in the table drive. The gear b is fast on a shaft c and the worm gearing is driven from a power shaft f through a slidable coupling. The cradle is moved along guides h by means of a screw j running in a nut i and connected to the hob carriage. The nut i is connected to an arm moving on a cam track m, the nut being thus rotated to compensate for the lack of uniformity of the table rotation due to the tangential movement of the cradle. The additional table rotation caused by the cradle travel is also compensated by corresponding differential movement of the hob. When the drive gearing is moved concentrically of the work table instead of tangentially the compensating means m may be dispensed with.
