Technical field
The present invention relates to a kind of machinery fields, and in particular to a kind of Annealing Protection pipe.
Background technique
Cold drawing is the one of the outer dimension for allowing it to generate plastic deformation steel application external force at normal temperature and being needed
Kind processing technology.Since metal is during cold deformation, crystal grain generates dislocation, and resistance of deformation improves, and attribute is deteriorated.In multiple tracks
In secondary drawing process or when final finished property is annealed, it just must carry out intermediate annealing (recrystallization annealing) and finished product moves back
Fire.Annealing furnace suitable for cold drawing steel is generally electrical heating shield type annealing furnace, this kind of type of furnace has relatively high cost performance, only
One is disadvantageous in that it without protective atmosphere, and the material after annealing has more oxide skin, especially some medium carbon alloy steels,
After bearing steel annealing, surface oxidation forms the spinel structure for being difficult to pickling, ball blast removal.If the oxide skin on surface cannot have
Effect is removed completely, is not only reduced production efficiency, but also will affect the surface quality of product, is not able to satisfy the need of client finally
It asks.
Summary of the invention
The present invention provides a kind of Annealing Protection pipe, to solve problem of oxidation of the material in annealing process.
In order to solve the above technical problems, a kind of Annealing Protection pipe provided by the invention is made of first segment and second segment, institute

It is provided with first flange and second flange, connecting hole is provided in the first flange and the second flange and by the company
It connects hole to be fastened together, the end face of the second flange is provided with seal groove, is placed with asbestos seal in the seal groove
Circle.
The quantity of the connecting hole is 8 and is evenly distributed in the first flange and the second flange.
The first flange and the second flange are fastened together by bolt, washer, nut.
It further include support plate, the support plate is arranged on the first segment and the second segment.
The quantity of the support plate is 6 groups.
Bring of the present invention the utility model has the advantages that a kind of Annealing Protection pipe provided by the invention by setting first segment, second segment,
First flange, second flange, seal groove, asbestos seal ring, support plate, so that material is in entire annealing process, Annealing Protection
Pipe can be good at the entrance for completely cutting off external oxidation gas, to guarantee material non-oxidation in entire annealing process.It uses
The advantages of Annealing Protection pipe can not only reach material surface non-scale, and the newly-increased of annealed material can be significantly reduced
Decarburized layer, and then production efficiency is improved, meet product quality.
Detailed description of the invention
Fig. 1 is the overall structure diagram of Annealing Protection pipe according to an embodiment of the present invention.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
Fig. 1 is the overall structure diagram of Annealing Protection pipe according to an embodiment of the present invention.Fig. 2 is to implement according to the present invention
The schematic enlarged-scale view in the region C in Fig. 1 of example.
A kind of Annealing Protection pipe provided by the invention is made of first segment A and second segment B, the first segment A and described
The end of two sections of B is both provided with dome head 1, and the junction of the first segment A and the second segment B are respectively arranged with the first method
Orchid 4 and second flange 6 is provided with connecting hole in the first flange 4 and the second flange 6 and is fastened by the connecting hole
It links together, the quantity of the connecting hole is 8 and is evenly distributed in the first flange 4 and the second flange 6.Institute
The end face for stating second flange 6 is provided with seal groove, and asbestos seal ring 5, the asbestos seal ring (5) are placed in the seal groove
It can also guarantee Annealing Protection pipe good sealing performance while bearing high temperature.
Furthermore, it is understood that the first flange 4 and the second flange 6 are fastenedly connected by bolt 3, washer 7, nut 8
Together.In addition, a kind of Annealing Protection pipe provided by the invention further includes support plate 2, the support plate 2 is arranged described first
On the section A and second segment B, the quantity of the support plate 2 is 6 groups, can prevent Annealing Protection pipe in heating process from deforming.
In the present embodiment, a kind of Annealing Protection pipe provided by the invention is two-part structure, by flanged joint at total
A length of 7.7m, diameter are the sealed shell of tank of 478mm.The round tube body of Annealing Protection pipe is using the rolling weldering of high-quality heat-resistance stainless steel plate
It is connected into shape, the first segment A length is 5.5m, and the length of the second segment B is 2.2m.The first segment A and second segment B
Round tube end portion be all welded with the dome head 1, the junction of the first segment A and the second segment B are respectively welded
There are the first flange 4 and the second flange 6.The end face of the second flange 6 is provided with the seal groove of two groups of 5*10, is used for
Place the asbestos seal ring 5 resistant to high temperature.8 bolts are evenly distributed in the first flange 4 and the second flange 6 to connect
