AI Technical Summary
The lining structure of the existing ladle bag has reduced life and safety in the flow of people and the rapid and cold hot environment. The existing solutions cannot meet the needs of safe production and are complex in maintenance and require a lot of manpower and material resources.
A multi-layer masonry structure is adopted with a cladding, permanent lining, intermediate layer working lining and inner layer working lining. The permanent lining and intermediate layer working lining are made of magnesium carbon bricks, and the inner layer working lining uses magnesium carbon bricks with the same taper, with thicknesses ranging from 70 to 90mm, 100 to 120mm and 120 to 140mm respectively. During masonry, the intermediate layer bricks and inner layer bricks correspond to the shapes to form a layered structure.
It realizes quick judgment and safe down-line repair of the ladle when the inner working lining is removed from bricks. The subsequent maintenance is simple, and the intermediate working lining only needs partial repair, which simplifies the maintenance process and improves the safety and reliability of the use process.

Abstract
Description
Technical Field
[0001] The utility model relates to a ladle, in particular to a masonry structure of a safe and reliable ladle. Background Technique
[0002] As a container for carrying molten steel and the operation of molten steel, the safety of the ladle determines the life safety of on-site construction and production workers. With the continuous update and iteration of special steel technology, the determination of the ladle inner lining has become the last line of defense to ensure the life safety of workers.
[0003] To ensure the safe operation of molten steel, experienced workers need to be arranged to track the operation of the ladle on site, and their work is mainly responsible for the determination of the ladle inner lining. This type of work requires a lot of manpower, material resources and a large amount of time to train. Once there is personnel flow, it is bound to form a safety hazard. At present, the output is insufficient and the production is intermittent. The ladle inner lining is affected by rapid cooling and heating, and its life and safety are extremely reduced. The existing permanent lining + working lining scheme can no longer meet the needs of safe production, so the scheme is improved. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a masonry structure of a safe and reliable ladle with safe use and simple maintenance.
[0005] To solve the above technical problem, the technical solution adopted by the utility model is: it includes a ladle shell, a permanent lining, an intermediate layer working lining and an inner layer working lining; the permanent lining is poured on the inner side of the side wall of the ladle shell, the intermediate layer working lining is built with intermediate layer bricks on the inner side of the permanent lining, and the inner layer working lining is built with inner layer bricks on the inner side of the intermediate layer working lining.
[0006] Further, the intermediate layer bricks and the inner layer bricks are made of magnesia-carbon bricks with the same taper.
[0007] Further, the inner shape of the intermediate layer bricks is the same as the outer shape of the inner layer bricks.
[0008] Further, the thickness of the permanent lining is 70-90 mm, the thickness of the intermediate layer working lining is 100-120 mm, and the thickness of the inner layer working lining is 120-140 mm.
[0009] The beneficial effects produced by adopting the above technical scheme are as follows: Once the whole brick of the innermost layer working lining of the ladle of the structure of the utility model falls off, it can be directly and safely determined that the ladle is taken off the line for repair or overhaul; for subsequent maintenance of the innermost layer working lining, it can be removed and measured for local replacement when the ladle is taken off the line for cold repair; for the intermediate layer working lining, only local spraying and leveling or patching are needed for defective or slightly eroded parts. The ladle of the structure of the utility model has the characteristics of simple and convenient masonry, safe and reliable use process and simple subsequent maintenance. Description of the Drawings
[0010] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0011] Figure 1 is a schematic structural view of the present utility model.
[0012] In the figure: ladle shell 1; permanent lining 2; intermediate working lining 3; inner working lining 4. Specific embodiments
[0013] Figure 1 As shown, the masonry structure of the present safe and reliable ladle includes a ladle shell 1, a permanent lining 2, an intermediate working lining 3 and an inner working lining 4, which are, from outside to inside, the ladle shell 1, the permanent lining 2, the intermediate working lining 3 and the inner working lining 4. The permanent lining 2 is formed by casting with a permanent lining castable. The permanent lining 2 is cast on the inner side of the side wall of the ladle shell 1 to form a layered structure with a thickness of 70 - 90 mm. The intermediate working lining 3 is built with intermediate bricks on the inner side of the permanent lining 2 to form a layered structure; the intermediate bricks are magnesia-carbon bricks, and the thickness of the intermediate working lining 3, that is, the thickness of the intermediate bricks, is 100 - 120 mm. The inner working lining 4 is built with inner bricks on the inner side of the intermediate working lining 3 to form a layered structure; the inner bricks are magnesia-carbon bricks, and the thickness of the inner working lining 4, that is, the thickness of the inner bricks, is 120 - 140 mm.
[0014] The intermediate bricks and the inner bricks are magnesia-carbon bricks with the same taper. Preferably, magnesia-carbon bricks of different model sizes are used. Preferably, when building, the inner shape of the intermediate bricks is the same as the outer shape of the inner bricks.
[0015] Figure 1 As shown, the masonry process of the masonry structure of the present safe and reliable ladle is as follows:
[0016] (1) First, build the intermediate working lining 3 with intermediate bricks, and leave a gap for casting the permanent lining 2 between the intermediate working lining 3 and the ladle shell 1 during building;
[0017] (2) For every 3 layers of intermediate bricks built, cast the castable of the permanent lining 2 between the intermediate bricks and the ladle shell 1; until the intermediate working lining 3 is built and the permanent lining 2 is cast;
[0018] (3) After waiting for the permanent lining 2 to dry, build the inner working lining 4 with inner bricks; after the inner working lining 4 is built, the masonry structure of the present ladle is obtained.
[0019] Once a whole brick falls off the inner working lining 4 of this ladle, it can be directly and safely determined that the ladle is taken out of service for repair or overhaul; for subsequent maintenance of the inner working lining 4, it can be waited until the ladle is taken out of service for cold repair, then removed and measured for local replacement; for the middle working lining 3, only local gunning for leveling or patching is needed for defective or slightly eroded parts.
