Abstract
The utility model relates to ladle nozzle seating bricks in a ferrous metallurgy industry, in particular to a combined type ladle nozzle seating brick capable of effectively prolonging service life. A ring-column-shaped carbonic machine-pressed core is inlayed in the position which is severely flushed by molten steel and is placed inside a nozzle seating brick molded by casting. The core is wrapped by a casting body, and then a combined type ladle nozzle seating brick is formed by means of the core and the casting body. The service life of the ladle nozzle seating brick is prolonged because of a good flushing-resistant property of a carbonic machine-pressed product.
Description
Affiliated technical field
The utility model relates to a kind of iron and steel metallurgical industry ladle nozzle brick cup, particularly relates to a kind of combined type ladle nozzle brick cup.
Background technology
The bottom of the ladle of steel industry splendid attire high-temperature molten steel is equipped with the mouth of a river and pocket block.Pocket block was directly built by laying bricks or stones at the bag end, packed in the pocket block in the mouth of a river, was the passage that molten steel is derived, and pocket block plays protection and positioning action to the mouth of a river.
Experience repeatedly colds and heat succeed each other in the ladle use, can produce strong thermal shock influence to pocket block; Ladle connects in the steel process high-temperature molten steel and also can produce intense impact and wash away pocket block.Thereby, require pocket block to have good thermal shock resistance and intensity.
Carbonaceous goods such as the magnesium carbonaceous of friction press or hydraulic press compression moulding or magnalium carbonaceous have higher thermal shock resistance and intensity, and the pocket block of general small-sized ladle is selected the carbonaceous article by friction press or hydraulic press compression moulding usually for use.And the pocket block of large and medium-sized ladle is relatively large because of volume, can't compression moulding, adopt moulding by casting usually.Because there is the defective of self in the ladle nozzle brick cup that casting forming method is produced, and is relatively poor like anti-molten steel scouring ability, causes service life shorter.
Summary of the invention
The utility model provides a kind of combined type ladle nozzle brick cup.Its concrete technical scheme is:
(1) ladle nozzle brick cup inside receives the most serious position of molten steel scouring to inlay an annulus cylindricality machine and presses the carbonaceous article inner core, and inner core and outside pour mass constitute combined type ladle nozzle brick cup.
(2) the annulus cylindricality inner core of inlaying except that inner surface with molten steel contacts, all the other each faces are all wrapped up by pour mass.
(3) the annulus cylindricality inner core of inlaying selects for use machine to press carbonaceous article, and material can be selected the magnesium carbonaceous for use, also can select the magnalium carbonaceous for use, is excellent with the magnalium carbonaceous.
(4) outside pour mass is formed by the high-strength castable cast.
The beneficial effect of the utility model is:
(1) utilizes machine to press the good characteristics of the anti-molten steel scouring performance of carbonaceous article, receive the most serious position of molten steel scouring to inlay an annulus cylindricality machine in ladle nozzle brick cup inside and press the carbonaceous article inner core, to improve the scour resistance of combined type ladle nozzle brick cup.
(2) the annulus cylindricality machine that will inlay with the high strength pour mass presses the carbonaceous article inner core to wrap up, and can prevent that inner core from coming off in production, transportation and use, further improves the stability in use of combined type ladle nozzle brick cup.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
Fig. 1 is a kind of combined type ladle nozzle brick cup generalized section of the utility model.
Mark is expressed as among the figure: 1-inner core, 2-pour mass.
The specific embodiment
With reference to Fig. 1, at first, inner core 1 is fixed with friction press or hydraulic press compacting inner core 1, use vibration moulding mode is cast in high-strength castable around the inner core 1, and inner core 1 constitutes the clad steel tundish nozzle pockets with high strength pour mass 2.
The foregoing description of the utility model only is to be given an example for what clearer explanation the utility model did, and is not the restriction of the utility model being made the enforcement mode.Technical staff for said field; On the basis of above-mentioned explanation, can also make other multi-form changes; This paper can't also need not make exhaustive to all embodiments, and the change that those spirit that belong to the utility model amplify out still is among the protection domain of the utility model.
Claims (4)
1. combined type ladle nozzle brick cup, its characteristic receive the serious position of molten steel scouring to inlay a machine and press inner core (1) in ladle nozzle brick cup pour mass inside.
2. a kind of combined type ladle nozzle brick cup according to claim 1 is characterized in that inner core (1) is the annulus cylindricality.
3. a kind of combined type ladle nozzle brick cup according to claim 1 is characterized in that each face of inner core (1) all the other except that inner surface is wrapped up by pour mass.
4. a kind of combined type ladle nozzle brick cup according to claim 1 is characterized in that inner core (1) material is that machine is pressed carbonaceous article.
