Abstract

The invention discloses an integral lining structure of a metal ladle for aluminum electrolysis, which comprises a lining brick structure forming a lining wall body, wherein the lining brick structure adopts an integral arc structure to improve the attaching degree and the lining integrity of the lining wall body and the metal ladle wall, and the edge part of the brick body of the lining brick structure adopts a stepped hasp type design to reserve an expansion joint. The utility model discloses an increase brick size effectively blocks aluminium liquid seepage way, the special construction that the arc design more pasted the clothing lateral wall in order to reduce brickwork joint quantity, hasp type, effectively solves because the ordinary brick size of metal covering inside lining is little, simple structure, and the main problems such as long, the difficulty of peeling off, the gap is more of building by laying bricks or stones that cause.

Description

Integral lining structure of metal ladle for aluminum electrolysis

Technical Field

The utility model relates to a metal ladle lining structure which is used in an electrolytic aluminum plant and needs to be periodically replaced such as an aluminum outlet ladle and an assembly workshop ladle.

Background

The production of industrial primary aluminum mainly adopts a molten salt electrolysis method, and the metal bag is mainly used for sucking out aluminum liquid and bearing molten iron for anode assembly in the daily production process. Different types of metal bags are required to be soaked and washed by high-temperature melt in the daily production process, and the maximum use temperature reaches about 1000 ℃, so that liners must be laid in the metal-clad steel structure, and on one hand, the liner material must have strong high-temperature resistance and on the other hand, the liner material must have the capability of coping with the washing of the high-temperature melt. Due to the special use environment, the lining of the whole inner wall needs to be stripped and replaced manually at regular intervals, and the problems of flying of harmful substances, difficult stripping of small bricks and the like exist during stripping.

In the prior art, the lining is built layer by staggered joints of refractory bricks with common sizes. The characteristics of the refractory materials on the market at present, such as aluminum two-man ladles, are that the lining is corroded about half a year and needs to be replaced. After one metal bag is damaged, the lining is replaced and the metal bag is built again, so that the process is complicated and the time is long. The small-size lining brick not only consumes time and labor during building, but also has the problems of difficult stripping and the like during cleaning. Moreover, as the lining bricks are small in size, the quantity of wall joints is increased, and high-temperature molten liquid inevitably overflows from the brick joints, so that the service life of the whole lining is influenced; the aluminum liquid overflows from the gap, and meanwhile, the loss of products is caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a whole inside lining structure of metal covering for aluminium electroloysis adopts whole, hasp type, the whole inside lining structure of arc to overcome prior art's not enough.

The technical scheme of the utility model is that:

the utility model provides an aluminium is whole inner lining structure of metal package for electroloysis, is including the inside lining brick structure that constitutes inside lining wall body, and this inside lining brick structure adopts whole arc structure in order to improve inside lining wall body and metal package wall's laminating degree and inside lining wholeness, and the expansion joint is reserved in the design of the brick body limit portion of this inside lining brick structure adoption cascaded hasp type.

Compared with the prior art, the utility model discloses an increase brick body size effectively blocks the special construction that aluminium liquid seepage route, arc design more pasted the clothes lateral wall in order to reduce brickwork joint quantity, hasp type, effectively solves because the ordinary brick size of metal covering inside lining is little, simple structure, and the main problems such as long consuming time, peel off difficulty, the gap is more of building by laying bricks or stones that cause.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The lining brick structure 1 of the utility model is as shown in figure 1: by adopting an integral arc structure and according to the sizes of different metal packages 2 and the design of the arc structure, the joint degree and the integrity of the lining between the lining wall body and the wall of the metal package 2 can be improved, the heat preservation uniformity of the material is improved, and meanwhile, the accumulation of aluminum liquid between the wall body and the wall of the metal package 2 is effectively prevented; the edge of the brick body is convenient to splice, a certain amount of expansion joints are reserved by adopting a stepped hasp type design, so that a space for releasing stress of materials due to thermal expansion is provided, and the stepped hasp type design can prevent aluminum liquid from leaking from brick joints, reduce the loss of the aluminum liquid, protect the interior of the brick body and prolong the service life of the lining; contrast the utility model discloses inside lining brick structure 1 and ordinary inside lining brick size, the utility model discloses when considering whole weight, increase inside lining brick size, can wholly reduce inside lining wall body overall brickwork joint quantity.

The utility model discloses when the assembly, as shown in figure 2: the lining of the lining brick structure 1 of the utility model is built from the bottom, from bottom to top, the upper and lower layer bricks need to be laid in staggered joints as shown in figure 2; each layer of hasp masonry.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.

Claims

1. The integral lining structure of the metal ladle for aluminum electrolysis is characterized in that: including inside lining brick structure (1) that constitutes inside lining wall body, this inside lining brick structure (1) adopts whole arc structure in order to improve the laminating degree and the inside lining wholeness of inside lining wall body and metal package (2) wall, and the expansion joint is reserved in the design of the brick body limit portion adoption cascaded hasp type of this inside lining brick structure (1).
