Description
Technical Field
The utility model belongs to the technical field of the steel ingot pouring is annotated to the mould, and specifically speaking relates to a scalable inert gas protection device.
Background
The existing inert gas protection device for pouring is a protection cover formed by enclosing a general annular steel plate, a row of small holes are formed below a steel pipe, and protective gas is blown out from the small holes from top to bottom to form a protective gas curtain to protect steel flow in pouring and prevent secondary oxidation. The above-mentioned techniques have the following drawbacks: firstly, the device has no telescopic range, can not adjust the height, can not be flexibly adjusted along with different types of moulds and different types of moulds of a steel casting vehicle and a casting pit, and needs to design protective covers with different applicable specifications of casting ingot types; and secondly, small blowing holes below the steel pipes are easily blocked by splashed steel slag, so that the service life of the protection device is short and the protection device needs to be frequently replaced.
SUMMERY OF THE UTILITY MODEL
Aiming at various defects in the prior art, the inventor researches and designs a telescopic inert gas protection device in long-term practice, and the telescopic inert gas protection device is provided with a telescopic sleeve in a protective sleeve, so that the flexible configuration of the protection device and different molds can be realized, the telescopic adjustment on the height can be realized, the height can be telescopically adjusted, the structure is simple, and the telescopic inert gas protection device is economical and durable.
In order to achieve the above object, the utility model provides a following technical scheme:
a telescopic inert gas protection device comprises a sealing plate and a protective sleeve. The sealing plate is positioned at the top of the protection device, and the protection sleeve is arranged on the lower surface of the sealing plate; an air chamber plate is arranged on the inner side of the upper end of the protective sleeve, and the top end of the air chamber plate is fixed on the lower surface of the sealing plate; the inner side of the lower end of the protective sleeve is provided with a telescopic sleeve, and the upper end of the telescopic sleeve is fixed with the protective sleeve through a fastener.
Further, the protective sleeve and the sealing plate are welded and fixed or integrally formed.
Further, the cross section of the air chamber plate is L type.
Further, a gap is arranged between the bottom end of the air chamber plate and the protective sleeve.
Further, the fastener is a bolt.
The utility model has the advantages that:
by arranging the telescopic sleeve in the protective sleeve, flexible configuration of the protective device and different molds can be realized, and telescopic adjustment on the height can be realized; meanwhile, inert gas is flushed into a cavity formed by the gas chamber plate and the protective sleeve, and the flow field of the inert gas can completely seal the space in the protective sleeve after casting, so that the problem of blocking of the gas hole of the protective device is solved, secondary oxidation of the injected flow caused by external air suction can be avoided, the service life is prolonged, and the application field is wider.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the following description is given with reference to the accompanying drawings of the present invention for clear and complete description of the technical solution of the present invention. Based on the embodiments in the present application, other similar embodiments obtained by persons of ordinary skill in the art without any creative effort shall fall within the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for the purpose of illustrating the present invention and not for the purpose of limiting the same.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1, the utility model discloses a scalable inert gas protection device, including closing plate 1 and protective sheath 4. closing plate 1 is located protection device's top, protective sheath 4 sets up at closing plate 1 lower surface, and with closing plate 1 below table welded fastening or with closing plate 1 integrated into one piece, be equipped with air chamber board 2 in 4 upper ends inboard of protective sheath, 2 top welded fastening of air chamber board is in the 1 lower surface of closing plate, and its cross-section is L type, be equipped with the gap between 2 bottoms of air chamber board and the protective sheath 4, be provided with the telescope tube 5 in 4 lower extreme inboards of protective sheath, the telescope tube 5 upper end is fixed with protective sheath 4 through fastener 3, this embodiment fastener 3 is the bolt, telescope tube 5 can stretch into different positions reuse fastener 3 in the protective sheath 4 according to actual need and.
When the protection device of this embodiment is used, sealing plate 1 is connected with ladle mechanism, need measure the position of loudspeaker brick apart from the mouth of a river during the connection, adjust the position of telescopic sleeve 5 through fastener 3 to confirm different positioning height, satisfy the requirement of inert gas protection when various ingot types are poured. Inert gas is supplied into a cavity formed by the air chamber plate 2 and the protective sleeve 4 in advance 1 minute before molten steel is poured, splashing during pouring can be effectively avoided, and the inert gas flows into the space in the protective sleeve through a gap between the air chamber plate 2 and the protective sleeve 4 after pouring. After the end of the casting, an inert gas was blown for a prolonged period of 1 minute.
The novel telescopic inert gas protection device adopts the telescopic sleeve arranged in the protective sleeve, can realize flexible configuration of the protection device and different molds, and realizes telescopic adjustment on the height; meanwhile, inert gas is flushed into a cavity formed by the gas chamber plate and the protective sleeve, and the flow field of the inert gas can completely seal the space in the protective sleeve after casting, so that the problem of blocking of the gas hole of the protective device is solved, the secondary oxidation of the injected flow caused by the suction of external air can be avoided, and the application field is wider.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
