Abstract
The utility model provides an insert tube connecting piece, which consists of a base, a connecting piece body and a casting material; the connecting piece body is a metal cylinder with an upper opening, a rectangular cross section and circular arcs on two sides, pouring materials are filled in the connecting piece body, and a base is welded at the lower end of the connecting piece body. The utility model discloses can eliminate the gunning dead angle, reduce because of the junction falls the lower coil frequency that the material caused, improve the insert tube life-span, reduction in production cost.
Description
Technical Field
The utility model belongs to the refining equipment field especially relates to a RH is concise with inserting pipe connection spare.
Background
The RH refining furnace is equipment for realizing an external refining process, can blow oxygen to raise the temperature, has the functions of decarbonizing, dehydrogenating, regulating the temperature of molten steel components and the like, and produces high-quality steel grades with high added values, such as silicon steel, automobile plates and the like.
The insert pipe is a key component of the RH vacuum chamber and is divided into an ascending pipe and a descending pipe, argon is introduced into the ascending pipe when molten steel is treated, the density of bubbles generated by the molten steel is reduced, the molten steel enters the vacuum chamber from the large tank through the ascending pipe under the vacuum pumping action of the vacuum pump, and the molten steel flows back to the large tank through the descending pipe under the action of gravity, so that the circulation of the molten steel is realized, and the molten steel is treated.
In the molten steel treatment process, the insertion pipe is inserted into molten steel, the insertion pipe is offline under the condition of severe castable crack, peeling and corrosion under the condition of flushing of the circularly flowing molten steel, spray repair maintenance is carried out after 3-4 tanks are treated, the gap between the ascending pipe and the descending pipe is a weak link of spray repair, the corrosion is severe at the position, the spray repair effect at the position is poor due to the limitation of narrow and small gap, the material is dropped off the line in the treatment process, the molten steel treatment is influenced, the service life of the insertion pipe is shortened, and the cost is increased.
Disclosure of Invention
The utility model provides a can eliminate the gunning dead angle, reduce because of the junction falls the lower coil frequency of material constitution, improve the insert tube life-span, reduce cost's insert tube connecting piece.
Therefore, the utility model discloses the technical solution who takes does:
an insert pipe connector comprises a base, a connector body and a casting material; the connecting piece body is a metal cylinder with an upper opening, a rectangular cross section and circular arcs on two sides, pouring materials are filled in the connecting piece body, and a base is welded at the lower end of the connecting piece body.
And the circular arc radiuses of the two sides of the metal cylinder of the connecting piece body are correspondingly selected according to the excircle radius of the connected inserting pipe.
The utility model has the advantages that:
by adopting the utility model, the dead angle of spray repair is eliminated, the off-line frequency caused by the falling of the material at the joint is reduced, the service life of the insert tube is prolonged, and the off-line time is reduced from 5 times per month before the change to one time after the change, and is reduced by 48 times all the year; the down-line frequency caused by the falling of the materials at the joint is reduced by 80 percent, and the use frequency of the insert tube is improved by 3 times, thereby greatly reducing the production cost.

FIG. 1 is a front cross-sectional view of an insert tube coupling;
fig. 2 is a top view of the insert tube coupling.
In the figure: base 1, connecting piece body 2, pouring material 3.
Detailed Description
As shown in figures 1-2, the insert tube connector of the present invention comprises a base 1, a connector body 2, and a casting material 3. The connecting piece body 2 is a metal cylinder with an upper opening, a rectangular cross section and circular arcs on two sides, the pouring material 3 is filled in the connecting piece body 2, and the base 1 is welded at the lower end of the connecting piece body 2. The circular arc radiuses on the two sides of the metal cylinder of the connecting piece body 2 are correspondingly selected according to the excircle radius of the connected insert pipe, namely, the circular arc radiuses are designed and manufactured according to the excircle radii of the connected ascending pipe and the connected descending pipe so as to ensure that the connection is close and tight.
The connecting piece body 2 is made of 2mm iron plates and is made into an iron cylinder with the height of 500mm, the width of 300mm, the length of 400mm and circular arcs on two sides. The base 1 is made of an iron plate with the thickness of 3mm, the length of 550mm and the width of 450 mm.
The connecting piece body 2 is arranged between the two insert pipes, the base 1 and the connecting piece body 2 are welded together, the pouring material 3 is filled from the opening, and the connecting piece can be baked for use after being dried for 12 hours.
Claims (2)
1. A connecting piece for an insert pipe is characterized by consisting of a base, a connecting piece body and casting materials; the connecting piece body is a metal cylinder with an upper opening, a rectangular cross section and circular arcs on two sides, pouring materials are filled in the connecting piece body, and a base is welded at the lower end of the connecting piece body.
