Description
Technical Field
The utility model belongs to the technical field of the metallurgy, especially, relate to an aspiration channel that is used for the mouth of a river toasts under the package in stopper stick.
Background
When a continuous casting machine produces various steels, an air suction type baking method is generally adopted for baking a drain opening of a tundish in a stopper rod, namely: the heat generated by burning the coal gas in the tundish is absorbed to the lower nozzle through the air suction pipe, and the lower nozzle is baked to meet the production requirement. Most of current aspiration channels are right-angled, and when mouth of a river under the stopper stick is baked, the slag on the ladle cover is heated and is melted once more and instil into well package, and the mouth of a river gets into the right angle department of aspiration channel under the well package again, and the aspiration channel is often blockked up, can't carry out normal the toasting, leads to well package mouth of a river to toast badly and arouse to open to water and hold the stream, still can cause vicious accident such as steel leakage when serious, brings very big hidden danger for safety in production.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing problem, the utility model provides an aspiration channel that mouth of a river toasted under being used for filling in stick is wrapped, this aspiration channel simple structure, it is convenient to use, can effectively prevent to block up, has ensured safety in production, has improved production efficiency.
In order to achieve the above object, the present invention adopts the following technical solutions, including:
the air inlet pipe comprises an upper opening and an air inlet pipe body connected with the upper opening, wherein the air inlet pipe body is linear, an extension part is arranged at the lower end of the upper opening and is arranged in the air inlet pipe body, the side wall of the air inlet pipe body is connected with an air inlet pipe, and an air outlet of the air inlet pipe is higher than a lower opening of the extension part.
The outer surface of the upper opening is connected with a pair of support handles which are in mirror symmetry.
The upper opening, the suction pipe body and the air inlet pipe are all made of steel or iron.
The utility model relates to an aspiration channel that is used for wrapping mouth of a river toasting in stopper stick, this aspiration channel simple structure, it is convenient to use, can effectively prevent to block up, has ensured safety in production, has improved production efficiency.
Drawings
Fig. 1 is a schematic view of the partial sectional structure of the front view of the present invention.
Fig. 2 is a schematic view of a partial cross-sectional structure of an original suction pipe.
Detailed Description
In order to make the skilled in the art have a more profound understanding of the present invention, a brief description will be made on the original suction pipe.
As shown in fig. 2, its aspiration channel body 12 of former aspiration channel is the right angle shape, when toasting the mouth of a river under the stopper stick package, the slag on the be covered is heated and is melted again and instil into the package, again from the package mouth of a river through the upper shed 11 entering aspiration channel body of aspiration channel, aspiration channel body 12 and air-supply line 14 often are blockked up, can't carry out normal toasting, lead to the package mouth of a river toast badly and arouse to open and water and hold and flow, still can cause vicious accidents such as bleed-out when serious, bring very big hidden danger for safety in production.
The present invention will be described in further detail with reference to the accompanying drawings so as to be more clearly understood by those skilled in the art, and as shown in fig. 1, the present invention includes:
the air suction pipe comprises an upper opening 1 and an air suction pipe body 2 connected with the upper opening, wherein the air suction pipe body is linear, an extension part 3 is arranged at the lower end of the upper opening and is arranged in the air suction pipe body, the side wall of the air suction pipe body is connected with an air inlet pipe 4, and the air outlet of the air inlet pipe is higher than the lower opening of the extension part.
The outer surface of the upper opening is connected with a pair of support handles 5 which are in mirror symmetry.
The upper opening, the suction pipe body and the air inlet pipe are all made of steel or iron.
When toasting, hold a pair of support handle on the surface of the upper mouth with the bracket, make the upper mouth cover and pack the mouth of a river under the stopper stick, open the air-supply line and start the equipment that induced drafts, at this moment, it is originally external to remove a small part air current by the air-supply line entering aspiration channel, most middle package internal hot air current gets into the aspiration channel body through middle package mouth of a river down, thereby the mouth of a river toasts under the centering package, because the aspiration channel body adopts the straight line form, avoided the jam to the aspiration channel body by the waste residue that the mouth of a river got into under the middle package, set up the inner wall that the extension can effectively prevent waste residue from the inner wall of the upper mouth trickles into the.
The utility model relates to an aspiration channel that is used for wrapping mouth of a river toasting in stopper stick, this aspiration channel simple structure, it is convenient to use, can effectively prevent to block up, has ensured safety in production, has improved production efficiency.
