Title: Method and apparatus for vacuum degassing of molten steel
Inventor: MORIYA NAONORI
IPC: C21C7/10
Filed: 1978-10-23
Abstract: PURPOSE:To improve the reflux efficiency and degassing efficiency of vacuum degassing treatment by dividing the lower opening end of a vacumm vessel to two paths, of which one is shorter, dipping the vessel deviatedly in a molten steel vessel and blowing inert gas toward the shorter path. CONSTITUTION:The lower opening end of a vacuum vessel 12 is divided by a partition plate 2 and the path 3 on the one side is notched of the outside circumferential edge part so that it is formed shorter than the other path 4. A porous plug P is mounted to the side wall of the partition plate 2 facing the path 3 side and a gas flow line 7 is formed to the porous plug P. This vacuum vessel 12 is dipped in the position deviated from the center in the ladle 10 under the molten steel surface with the path 3 being positioned closer to the center of the ladle 10. Inert gas is then blown from the porous plug P. The rising flow of the molten steel by the gas blow ascends in the shorter path and is exposed to vacuum, after which it goes beyond the back part of the partition plate 2, goes down the inside of the path 4 and is discharged to the deep part near the inside wall of the ladle 10. Thereby, the entire part of the molten steel in the ladle 10 is effectively mixed and evened.

IPC: B21C47/02
Filed: 1991-05-01
Abstract: PURPOSE:To prevent a worker from coming into contact with the spring up of a cut end and a coil end at the time of the overhaul of a band by controlling a rotating speed of a wire receiving turntable and preforming roll in synchronism with each other based on set information from a rotating speed, time setting means. CONSTITUTION:First, after a pattern of wave cycle is set and speed and time are set, a wire drawing machine is operated. At this time, the operation of the wire drawing machine is linked to the operation of a wire receiving turntable 95. The wave operation is performed by a number of rotation and a time setting means. At that time, the wire receiving turntable 95 and preforming rolls 14 are linked to each other and the number of rotation of a turntable driving motor is changed by the set wave cycle. Therefore, since the coiling machine of a wire shaped body is put into wave operation according to the number of rotation, the set time, etc., and they can be set and selected arbitrarily, the style of packing for taking up the wire shaped body coil is improved and when the band is overhauled, the cut end is prevented from generating spring up or the worker is prevented from coming into contact with the spring up at the coil end.
