Description

Long-life ladle

Technical Field

The utility model belongs to the technical field of the ladle structural design, concretely relates to long-life ladle.

Background

With the continuous forward development of the steel-making process. In order to meet the requirements for smelting special steel, reduce production cost, shorten the smelting time of a converter and an electric furnace and produce high-quality steel, steel mills have higher and higher requirements for molten iron quality. The method is developed from the prior art without pretreatment to the prior art of carrying out pretreatment processes such as desulfurization, dephosphorization and desilicication on molten iron in a foundry ladle. This makes the working conditions of the refractory layer of the foundry ladle more and more severe, and besides cracks and spalling caused by severe slag iron impact and temperature change, the refractory layer is also severely eroded by the desulfurization and dephosphorization agents, such as fluorite, iron scale, lime, iron oxide and soda, so that the service life of the foundry ladle is greatly reduced.

The ladle body part of the existing ladle is built by adopting refractory bricks, and in order to pour molten iron conveniently, a ladle nozzle is designed at the upper part of the ladle, as shown in figures 3-4, after the wall brick of the traditional ladle is built, a mould is arranged on the wall brick, and the pouring material is knotted only at the position of the ladle nozzle 3 to form a ladle nozzle pouring material 7, so that the problem that the service life of the ladle is shortened due to the fact that the top wall brick 6 of the ladle and the ladle nozzle pouring material 7 are easy to ditch and leak iron in the seam area is caused; in addition, as the top ladle wall brick 6 is not built into a circular ring structure in the ladle, the problem that the ladle wall brick falls off due to no support after thermal expansion is easily caused, and the normal use of the ladle is influenced.

Disclosure of Invention

The utility model discloses a solve above-mentioned technical problem, provide a long-life ladle, its structural design is simple reasonable, it is convenient to use, changes traditional package wall brick with package mouth position wait high into the pouring material to tie a whole with package mouth pouring material, avoid appearing the problem of seam position abnormal erosion, adopt antiseized sediment package mouth pouring material simultaneously, can reduce the sediment work of hanging of ladle operation process in a large number, improve the life of ladle.

The utility model adopts the technical proposal that: the utility model provides a long-life ladle, includes the box hat, and the package mouth of the inside out extension of top shaping of box hat, the inner wall and the bottom of box hat have all been built by laying bricks or stones and have been able to bear or endure firebrick, and the firebrick upper surface of box hat inner wall department is less than a package mouth position, and the inner wall department integrated into one piece of box hat inner wall top position and package mouth has the same material of pouring of thickness and firebrick thickness.

And the inner wall of the top of the steel shell and the inner wall of the ladle nozzle are provided with anchoring nails for reinforcing the casting material.

The anchoring nails are welded on the inner wall of the top of the steel shell and the inner wall of the ladle nozzle.

This kind of long-life ladle utilizes the pouring material to tie into a whole with shell iron inner wall top and package mouth inner wall position, fixes through the anchor nail, can avoid the juncture between resistant firebrick of traditional mode and the package mouth pouring material to produce the problem of erosion, play ditch and hourglass iron to replaced traditional shell iron top package wall brick and do not have the structure of support after the thermal expansion, prevented that resistant firebrick from appearing droing, the effectual life who improves the ladle.

The upper surface of the refractory brick at the inner wall of the steel shell is lower than the position of the ladle nozzle, and pouring materials with the thickness the same as that of the refractory brick are integrally formed at the top position of the inner wall of the steel shell and the inner wall of the ladle nozzle; the purpose of this is: to traditional resistant firebrick, because the firebrick can't be built by laying bricks or stones to ladle mouth position, consequently, the package wall brick at traditional box hat top can't carry out the annular and build by laying bricks or stones, when the ladle during operation, because be heated and produce the inflation of resistant firebrick, under the unsupported condition, resistant firebrick very easily produces and drops, for avoiding the appearance of this kind of problem, replace original ladle top resistant firebrick for the pouring material to with the pouring material integrated into one piece of ladle mouth inner wall, firstly can avoid taking place between resistant firebrick and the pouring material of package mouth the problem of tapping, the hourglass iron, secondly can avoid droing of resistant firebrick, thereby the life of extension ladle.

The utility model has the advantages that:

the utility model relates to a simple structure, it is convenient to use, changes traditional package wall brick with package height such as mouth position into the pouring material to tie a whole with package mouth pouring material, avoid appearing the problem of seam position abnormal erosion, adopt antiseized sediment package mouth pouring material simultaneously, can reduce ladle operation process in a large number and hang sediment work, improve the life of ladle.

fig. 2 is a top view of the present invention;

FIG. 3 is a prior art ladle construction;

figure 4 is a top plan view of a prior art ladle.

The labels in the figure are: 1. a steel shell; 2. a refractory brick; 3. wrapping a mouth; 4. pouring a material; 5. anchoring nails; 6. the top is wrapped with wall bricks; 7. and (5) pouring a material for coating the nozzle.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1-2, the long-life ladle comprises a steel shell 1, a ladle nozzle 3 extending outwards is formed at the top of the steel shell 1, refractory bricks 2 are built on the inner wall and the bottom of the steel shell 1, the upper surface of the refractory brick 2 at the inner wall of the steel shell 1 is lower than the lowest point of the ladle nozzle 3, and pouring materials with the thickness same as that of the refractory bricks 2 are integrally formed at the top of the inner wall of the steel shell 1 and the inner wall of the ladle nozzle 3.

The anchor nail 5 that is used for carrying out the reinforcement to pouring material 4 is all installed to the inner wall department of 1 top inner wall of box hat and package mouth 3, and anchor nail 5 welds in 1 top inner wall of box hat and package mouth 3 inner wall positions, consolidates pouring material 4 through anchor nail 5, can improve pouring material 4's structural stability, increase of service life.

This kind of long-life ladle utilizes pouring material 4 to tie a knot with 1 inner wall top of box hat and 3 inner wall positions of package mouth into a whole, fixes through anchor nail 5, can avoid the juncture between 2 of resistant firebrick and the package mouth pouring material 7 of traditional mode to produce the problem of erosion, play ditch and hourglass iron to replaced 1 top package wall brick 6 of traditional box hat not have the supported structure after the thermal expansion, prevent that resistant firebrick 2 from appearing droing, the effectual life who improves the ladle.
