Title: Continuous casting apparatus for cast strip
Inventor: YASUDA KAZUMI
IPC: B22D11/06
Filed: 1988-09-20
Abstract: PURPOSE:To produce a cast strip without any casting fin by thermal-spraying or coating refractory having low wettability to molten metal on surface of a weir regulating width direction of pouring basin part and surface part of a metallic belt contacting with the weir. CONSTITUTION:The side weir 11 forms the refractory layer 14 at the bottom face contacting with the metallic belt 1 and neighborhood thereof. The refractory layer 17 is formed at the surface part of the metallic belt 1 contacting with the side weir 11, too. As material of the refractory, the refractory having low wettability to the molten metal, such as zirconia, is used. The molten metal poured into the pouring basin part 5 has large contacting angle to the refractory layers 14, 17, and invasion into gap 15 between the metallic belt 1 and the side weir 11, is restrained. By this method, penetration developing between the side weir and the metallic belt is restrained and the cast strip without any casting fin is produced and as the separatibility from continuous casting machine is good, the casting condition can be stabilized.

IPC: B24B27/06
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent any system trouble such as a sudden wire disconnection or the like by measuring a form variation in the outer diameter of a tubular part in and around the vicinity of a flange part of a wire bobbin, detecting a form variation in a wire bobbin body, and compensating a winding form in linkage with a traverser unit. SOLUTION: At the time of starting the winding of a wire, the outer diameter of a tubular part in and around the flange of two wire bobbins 5 and 6 is measured and also any outer diametral variation of this tubular part is detected. As to a judgment of deformation in tubular vertical ends of these wire bobbins 5 and 6, a combination of both infrared ray emitting and receiving devices is available. A form judger 22 measures an outer diameter of the tubular part by an outer diameter variation signal R. Control after form judgment is carried out by a position controller 23 controlling a position of the traverser unit. Concretely, in the case where the tubular part itself has become thickened, an amount of travel of a traverser is reduced, and in the case where it has become slenderized the other way, the travel of the traverser is controlled for increment.
