ELECTRICAL CONDUCTION CONNECTING DEVICE OF ROLLER

摘要

PURPOSE:To perform electrical conduction connection of a roller for the electromagnetic stirring device of a continuous casting machine in a superior state by joining the two slopes of the recessed surface formed at the shaft end of said roller and the two joining surfaces of the raised part of a revolving conductor to be fitted into the recessed surface. CONSTITUTION:A revolving conductor 18 and a bolt 23 are disposed to the recessed part 14 of the frame 6 of a roller for stirring the unsolidified part in an ingot in a continuous casting machine, and a strapped plate 24 is secured to the frame 6 by means of a bolt 25. An insulation plate 7 is mounted to the front end face of a bearing 5, and the raised part 19 of the conductor 18 is fitted into the recessed part 3 of an auxiliary conductor 2, thence the frame 6 is abutted on the shaft end of the roller 1 and the stud bolt 9 mounting the insulation plate 7 to the bearing 5 is fixed to the frame 6. At this time, a hexagonal socket head bolt 23 is screwed into a screw hole 2', to join both joining surfaces 20 to both slopes 4 respectively and secure the conductor 18 to the conductor 2. Further a cover 35 is put on the front end psrt of the frame 6 whereby the electrical conduction connecting device is assembled.
