Title: Method for suppressing vortex of molten steel in tundish in continuous casting
Inventor: TACHIBANA SHIGEO
IPC: B22D11/103
Filed: 1980-05-01
Abstract: PURPOSE:To prevent the slag on the surface from being included into molten steel and improve the yield of molten steel by acting a magnetic field which prevents the vortex at nozzle inlet when the molten steel level in a tundish lowers below a prescribed value. CONSTITUTION:A magnetic field coil 5 is wound around a tundish nozzle 3, and when the surface level of the molten steel 2 in a tundish 1 lowers below the prescribed value, electric conduction is applied to the coil 5, thereby negating the formation of the vortex generated in the molten steel. Slag 4 is prevented from being included in the molten steel by the above method despite lowering of the surface level below the prescribed value, and therefore the yield of the molten steel is correspondingly improved.

Abstract: PURPOSE:To obtain a liquid treating method free from the generation of stain or discoloration by executing an operation to dip a work with the top upward and to take it out with the top downward in the liquid treating method of the cap like work. CONSTITUTION:The cap like work 1 is loaded with the top of the work 1 faced to the bottom side of a casing 7 and when a hoisting accessory 14 is at the upper position of the liquid vessel 8, the casing 7 is hung to face the bottom side upward and dipped into the liquid vessel 8 to face the bottom side downward by turning the casing 7 when the hoisting accessory descends. Air pocket is not generated since the work 1 is dipped with the top of the work 1 faced downward. Next, when the hoisting accessory 14 ascends, the casing 7 is hung to face the bottom upward by reversely turning the casing. The scooping up of the liquid is not generated since the top of each work 1 is upward, that is, the opening part is downward. Further, the work 1 is dried by inclining it on a dryer. As a result, a series of liquid treating operation with many liquid vessels successively formed is facilitated and easily automated.

     CONSTITUTION: The base end of metallic bellows 23 is fixed over the entire circumference of a web part of a supporting member 17 for a rectangular frame-shaped sealing member (a) fitted to partitioning members, and an opening part of a silicone-made gas bag 30 is fitted over the entire circumference of a supporting member 17' for a sealing member (b) which is placed on the outside of the sealing member (a) in a coaxial manner. When desorption is conducted by heating an adsorption in the desorption zone, pressurized water is introduced into the bellows 23 and the bag 30 through a conduit to expand the bellows 23 and the bag 30, whereby they are closely contacted to a pressure-receiving part 29 of a column 8 so as to secure airtight sealing. Accordingly, the hot gas in the desorption zone is prevented from leaking to the exterior, and a fire accident is prevented from being caused by the penetrating of oxygen-containing exhaust gas. When the desorption is completed, the pressurized water is discharged from the bellows 23 and the bag 30, and the compartment in the desorption zone is moved to the next zone.
