Abstract
The utility model discloses a ladle nozzle brick cup and belongs to the technical field of metallurgy. The ladle nozzle brick cup is characterized in that the inner wall of the nozzle brick cup is of a step type and is provided with a step. According to the ladle nozzle brick cup disclosed by the utility model, a traditional nozzle brick cup is improved so as to protect an upper nozzle and the inner wall of the nozzle brick cup, and therefore, the damage to the inner wall of the nozzle brick cup and the outer wall of the upper nozzle is small during the cleaning process of the nozzle brick cup, the service life of the nozzle brick cup is prolonged, the cost is reduced, and the labor strength of workers is reduced.
Description
Technical field
The utility model relates to a kind of ladle pocket block, belongs to metallurgical technology field.
Background technology
Ladle furnace use pocket block endoporus mostly adopts the shape such as the mild diffusion of Fig. 1, adopts in the pocket block use procedure of this shape well damage to occur, easily will the pocket block inwall and the filling pipe end outside damage, affect pocket block and filling pipe end service life.Wrap the such pocket block of use in large-scale steel mill, particularly Large Steel, only have service life about 12 times, can have a strong impact on the production process of steel mill, increase ladle light maintenance number of times, and the frequency of changing pocket block.
Summary of the invention
In order to overcome above-mentioned deficiency; the utility model provides a kind of ladle pocket block; existing pocket block is improved; with protection filling pipe end and pocket block inwall; guarantee that pocket block inwall in scale removal process is little with the damage of filling pipe end outer wall; improve the pocket block filling pipe end life-span, reduce cost, reduce labor strength.
The technical solution adopted in the utility model is: a kind of ladle pocket block is characterized in that: the pocket block inwall is notch cuttype, is provided with the one-level step.
The pocket block that the utility model provides, inwall are provided with the one-level step, such as Fig. 2.The utility model is wrapped use at Large Steel, and the position of flue is no more than this step when cleaning after using.
The ladle pocket block that the utility model provides, reasonable in design, can protect upper surface and filling pipe end and the pocket block contact site of filling pipe end, the whole inwall of protection pocket block is not damaged when flame cleans.After adopting the utility model, the pocket block Service life stops wrapping number of times, the corresponding raising of ladle life thereby reduce ladle more than one times.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is the cutaway view of existing ladle pocket block.
Fig. 2 is the cutaway view of the utility model ladle pocket block.
The specific embodiment
Embodiment:
Fig. 1 is prone to badly damaged for the cutaway view of existing ladle pocket block, pocket block inwall is the shape of mild diffusion in the use procedure; Fig. 2 is the cutaway view of the utility model ladle pocket block, and the pocket block inwall is notch cuttype, is provided with the one-level step.
The utility model is by following scheme implementation: use special purpose model when manufacturing pocket block, directly pour into shape as shown in Figure 2.
Taiyuan Iron and Steel Co. the second steel mill this device on probation, 180 tons of carbon steels wrap adopted the pocket block that notch cuttype arranges after, greatly improve service life, former pocket block can only use 20-30 just replacings with 7-8 times after improving, substantially and the air brick life-span synchronous.Wrap at 180 tons of stainless steels and also to have used the utility model device, pocket block life-span and filling pipe end life-span improve synchronously, and former pocket block is with about 5 times, the last improving available 15-20 times.
