Abstract
The utility model relates to a ladle for steel production, which consists of a ladle wall, a high aluminium castable layer in the ladle wall, a molten pool brick layer, and nozzle bricks on the bottom of the ladle, and is characterized in that after the molten pool brick layer of the ladle is descended by 200 to 600mm, a trapezoid molten pool corrosion-proof layer with the same height as the descending height is laid on the molten pool brick layer of a deslagging surface; the molten pool corrosion-proof layer protrudes the molten pool brick layer to form a step; and the protruding length of the step is between 20 and 60mm. The utility model can improve using period of the ladle, i.e. increases the using times to 130 times from original 100 times, obviously reduces cost, and also improves operating rate of a machine set.
Description
Technical field
The utility model relates to steelmaking equipment, especially belongs to make steel the ladle of usefulness.
Background technology
Ladle is one of visual plant of steel-making, and the length in its service life has direct influence to the cost of manufacturing enterprise.At present deslagging face erosive velocity is inconsistent in the use of CSP ladle, causes that ladle deslagging face ladle molten bath brick and slag line brick are residual thickly to differ 30～50 millimeters, makes ladle molten bath brick and slag line brick can not reach balanced and consumes, and has a strong impact on the service life of whole ladle.By analysis, think its immediate cause be the molten bath brick layer height of ladle deslagging face and planform unreasonable due to.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can improve the service life of ladle, molten bath brick layer structure and the rational molten steel ladle of shape in the ladle.
Realize the technical measures of above-mentioned purpose:
A kind of molten steel ladle, nozzle brick by the high alumina casting bed of material in ladle wall, the ladle wall, molten bath brick layer, ladle bottom is formed, it is: ladle molten bath brick layer is descended on the molten bath brick layer of the deslagging face after 200～600 millimeters, build the trapezoidal molten bath anticorrosion layer that equates with falling head by laying bricks or stones; The molten bath anticorrosion layer protrudes molten bath brick layer and forms step, and the protrusion length of its step is 20～60 millimeters.
The utility model compared with prior art, it can improve the life cycle of ladle, promptly is increased to for 100 times 130 times by original use, reduces cost significantly, has also improved the unit operation rate simultaneously.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1
The specific embodiment
Be further described below in conjunction with accompanying drawing:
A kind of molten steel ladle is made up of the nozzle brick 4 of the high alumina casting bed of material 2 in ladle wall 1, the ladle wall 1, molten bath brick layer 3, ladle bottom.As for to wrap transformation at raw steel, 200 millimeters/300 millimeters/500 millimeters/600 millimeters height then falls the molten bath brick layer in the ladle 3 earlier; As the coming of new ladle, the height of the molten bath brick layer 3 of then being built by laying bricks or stones is lower than 200～600 millimeters of slag line brick height; And then build by laying bricks or stones in brick layer 3 upper end, molten bath that ladle deslagging face 5 is built by laying bricks or stones highly be 200 millimeters/300 millimeters/500 millimeters/600 millimeters or equate with selected height, low wide and up narrow trapezoidal molten bath anticorrosion layer 6, its trapezoidal molten bath anticorrosion layer 6 and molten bath brick layer 3 form that to protrude length be 20 millimeters/30 millimeters/50 millimeters/60 millimeters step 7.Owing to set up trapezoidal molten bath anticorrosion layer 6, itself and slag line brick can reach balanced and consume, thus the service life of having improved ladle.
