Abstract
The utility model discloses a steel ladle bottom structure capable of effectively reducing the amount of residual molten steel of a steel ladle. A steel ladle bottom area provided with a steel ladle nozzle brick cup is arranged to be a low concave area, and a slag blocking dam with the height of 300mm is arranged at the position, close to the nozzle brick cup, of the ladle wall portion. The steel ladle bottom structure has the advantages that due to the facts that the steel ladle bottom area provided with the steel ladle nozzle brick cup is arranged to be the low concave area and the slag blocking dam with the height of 300mm is arranged at the position, close to the nozzle brick cup, of the ladle wall portion, with the structure, the amount of residual molten steel is effectively reduced, and meanwhile entrapped slags in the process of molten steel pouring can be prevented.
Description
Technical field
The utility model belongs to fire resisting material field, is specifically related to a kind of bottom of steel ladle refractory material laying structure.
Background technology
In steelmaking process, molten steel in the ladle all is then to enter conticaster by ladle pocket block-filling pipe end-slide plate-lower mouth of a river, the ladle molten steel cast is too much by the residual remaining steel in normal appearance bottom, generally all can reach about the 1-10 ton, and the recovery rate of every Baogang water reduces.Because the eddy current effect of steel ladle pouring later stage is also obvious, the eddy current effect meeting in the pouring molten steel process is rolled in the molten steel part slag, affects steel quality.Along with improving constantly of process for making, steel mill is also more and more higher for the requirement of the quality that improves molten steel, increase molten steel recovery rate, the waste of minimizing molten steel.The at present common employing of ladle of steel mill is flat, because molten steel residual (loss), lower slag slag amount are relevant with the bottom of steel ladle area.Therefore can by change pocket block height at the bottom of the flat pouring type of bottom of steel ladle, the bag, pocket block position increase dam to reduce molten steel residual, prevent that slag is all highly beneficial in the pouring molten steel process.
Summary of the invention
For the problem that exists in the background technology, the utility model provides a kind of bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount.
The technical solution adopted in the utility model is as follows: a kind of bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount, it is characterized in that: the bottom of steel ladle region division that ladle pocket block is set is the indentation zone, increases the dam of 300mm near the Bao Bi position setting of pocket block.
The bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount of the present utility model, described indentation zone is than the low 50mm in whole bottom of steel ladle plane.
The bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount of the present utility model, whole bottom of steel ladle is clinoplain, described indentation zone is the lowest part of clinoplain.
The utlity model has following beneficial effect: the bottom of steel ladle region division that ladle pocket block is set owing to bottom of steel ladle structure of the present utility model is the indentation zone, and at the Bao Bi position near pocket block the dam of increasing 300mm is set, it is residual that such structure has effectively reduced molten steel, can prevent slag in the pouring molten steel process simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
As shown in Figure 1, a kind of bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount comprises bottom of steel ladle 1, bottom of steel ladle 1 ladle pocket block 2 zones are set, namely such as ab zone among Fig. 1, this zone is set to the indentation zone.And this indentation zone is than the low 50mm in whole bottom of steel ladle plane.Further, the Bao Bi position near pocket block is provided with the dam 3 of increasing 300mm.Concrete construction method is as follows: before the bottom of steel ladle cast, ladle pocket block top preset die makes near the indentation zone (about low 50mm) that forms of pocket block, increases 300mm near the Bao Bi position of pocket block and sets up dam.During the bottom of steel ladle cast, all the other positions are still watered flat, make ladle bottom that lowered zones be arranged, and convenient tapping reduces slag.Also can in the specific implementation, a guiding steel flow be set to the groove of lowered zones at the bag end simultaneously.
As shown in Figure 2, a kind of bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount comprises bottom of steel ladle 1, and whole bottom of steel ladle 1 is clinoplain.Bottom of steel ladle 1 ladle pocket block 2 zones are set, namely such as cd zone among Fig. 1, this zone is the lowest part on whole bag slanted floor plane, namely this zone is lowered zones.Further, the Bao Bi position near pocket block is provided with the dam 3 of increasing 300mm.Concrete construction method is as follows: before the bottom of steel ladle cast, and 2 ° of placements of ladle inclination (determining at pocket block position pad high altitude according to the ladle diameter).This scheme advantage: ladle is still placed cast by present inclination mode, and pouring type is with identical at present, and pour into a mould the bottom of steel ladle casting area is a plane at every turn, does not need the deflecting slope, constructs relatively simple.Molten steel can all go out to the greatest extent, thoroughly solves the surplus steel problem of bottom of steel ladle.
Claims (3)
1. bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount is characterized in that: the bottom of steel ladle region division that ladle pocket block is set is the indentation zone, near the Bao Bi position of pocket block the dam of increasing 300mm is set.
2. the bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount as claimed in claim 1, it is characterized in that: described indentation zone is than the low 50mm in whole bottom of steel ladle plane.
3. the bottom of steel ladle structure that can effectively reduce ladle residual molten steel amount as claimed in claim 1, it is characterized in that: whole bottom of steel ladle is clinoplain, described indentation zone is the lowest part of clinoplain.
