Description
Technical Field
The invention relates to a connecting piece for the on-line solid melting of metal steel pipes one by one.
Background
The existing metal steel pipe can not continuously operate on line one by one when the solid melting process is carried out, inlet openings are easily misaligned when the metal steel pipe enters a solid melting furnace, and air on the inner wall of the metal steel pipe is not easy to evacuate, so that oxidation is easily caused.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a connecting piece for the gradual online solid melting of metal steel pipes.
In order to achieve the purpose, the invention adopts the following technical scheme: the connecting piece comprises a first tubular head, a second tubular head and a connecting portion, wherein one end of the first tubular head is connected with the connecting portion, a first opening is formed in the other end of the first tubular head, one end of the second tubular head is connected with the connecting portion, a second opening is formed in the other end of the second tubular head, a plurality of air inlets are distributed in the connecting portion, and the air inlets are communicated with the first opening and the second opening.
The invention has the beneficial effects that: the structure is simple, the one-by-one online continuous operation can be realized, and the inlet of the solid melting furnace with the next metal steel pipe in alignment is avoided; has guiding function; the air inlet of the connecting piece can rapidly enter hydrogen after entering the solid smelting furnace, and the hydrogen enters the inner wall of the metal steel pipe along the connecting piece and is discharged out of the air on the inner wall of the metal steel pipe, so that the oxidation of the inner wall of the metal steel pipe is avoided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.
A partition is arranged between one end of the first tubular head and one end of the second tubular head of the channel on the inner side of the connecting part, and a plurality of air inlets are uniformly distributed on two sides of the partition and communicated with the corresponding first openings and the second openings.
The size of the first tubular head and the size of the second tubular head are consistent with the size of the inner diameter of the first metal steel pipe correspondingly connected.
The metal steel pipe branch-by-branch online solid melting process comprises the following steps:
the first step is as follows: conveying the first metal steel pipe 1 into a solid melting furnace through a conveying device for solid melting treatment;
the second step is that: the head end of a second metal steel pipe 2 is connected with the tail end of the first metal steel pipe through a connecting piece 3 and enters a solid melting furnace along with the first metal steel pipe for solid melting treatment;
the third step: the head end of the third metal steel pipe is connected with the tail end of the second metal steel pipe through a connecting piece and enters the solid melting furnace along with the second metal steel pipe for solid melting treatment; sequentially operating, and continuously feeding a plurality of metal steel pipes into a solid melting furnace one by one to perform solid melting treatment;
the fourth step: and separating the first metal steel pipe and the second metal steel pipe which are subjected to solid melting treatment through the solid melting furnace, taking away the connecting piece, placing the first metal steel pipe, and sequentially operating.
The metal steel pipes are gradually supported by the connecting piece which is fixedly melted on line, one end of the connecting piece is a first tubular head 4 matched with the inner wall at the tail end of the metal steel pipe, and the other end of the connecting piece is a second tubular head 5 matched with the inner wall at the head end of the metal steel pipe. The outer diameter of the first tubular head is matched with the diameter of the inner wall of the tail end of the metal steel pipe; the outer diameter of the second tubular head is matched with the diameter of the inner wall of the front end of the metal steel pipe.
One end of the first tubular head is connected with the connecting part, and the other end of the first tubular head is provided with a first air outlet.
One end of the second tubular head is connected with the connecting part 6, and the other end is provided with a second air outlet.
The metal steel pipe is fixedly fused on the connecting piece one by one, and a connecting part is also arranged between the first tubular head and the second tubular head.
The metal steel pipe is gradually supported by the connecting piece which is fixedly melted on line, the connecting part is provided with an air inlet 7, and the inside of the connecting part is communicated with the first tubular head and the second tubular head.
The metal steel pipes are fixedly fused on line one by one, the first tubular head is provided with a first inner cavity 8, one end of the first inner cavity is connected with an air inlet, and the other end of the first inner cavity is provided with a first air outlet; the second tubular head is provided with a second inner cavity 9, one end of which is connected with the air inlet, and the other end of which is provided with a second air outlet.
The metal steel pipes are gradually supported by the connecting piece which is in on-line solid melting, hydrogen is introduced into the solid melting furnace, and enters the metal steel pipes through the air inlet holes to discharge the air in the metal steel pipes.
The continuous online operation can be realized one by one, and the next metal steel pipe is prevented from aligning with the inlet of the solid melting furnace; has guiding function; the air inlet of the connecting piece can rapidly enter hydrogen after entering the solid smelting furnace, and the hydrogen enters the inner wall of the metal steel pipe along the connecting piece and is discharged out of the air on the inner wall of the metal steel pipe, so that the oxidation of the inner wall of the metal steel pipe is avoided.
Is used for the solid melting process of the ultra-long pipe.
The diameter of the connecting part does not exceed the outer diameter of the metal steel pipe.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
