Abstract
The utility model relates to a combined-type continuous casting tundish current regulator which comprises a body and a notch formed on the body. A base plate fixing groove is placed below the notch formed on the body. A base plate is placed inside the base plate fixing groove and integrates with the body. The combined-type continuous casting tundish current regulator is good in whole performance and without waste defects. Anti-erosion and washing-resisting ability of the combined-type continuous casting tundish current regulator is substantially improved. The combined-type continuous casting tundish current regulator can be used for up to more than 40 hours, and service life prolongs by twice. Moreover, in the prior art, when products are poured in a continuous casting tundish for 13-15 hours, because the inner core of a current regulator floats and the bottom of the tundish is penetrated, accidents of tundish-penetrating and non-planed stop-pouring happens a lot, and therefore the combined-type continuous casting tundish current regulator is high in safety and reliability, applied to all kinds of continuous casting tundishes, capable of substantially prolonging service life of the tundishes, reducing consumption of continuous casting materials, and remarkable in economical benefit.
Description
Technical field
The utility model relates to the Ferrous Metallurgy equipment technical field, is specifically related to a kind of flow straightener, particularly a kind of composite continuous casting tundish current stabilizer of long service life.
Background technology
The flow straightener structure is have hollow lumen container-like in the prior art, and this traditional flow straightener structure is the composite sleeve type, and the flow straightener inner chamber is set in the monolithic case by magnesia carbon brick and magnesia prefabricated section, and sandwich construction is used for the continuous casting tundish.Traditional flow straightener complex structure, layering is many, layer and layer in conjunction with deficient in stability, damage easily appears in the process of using.The problem that traditional flow straightener in use occurs is: large because of casting stream, bottom, the sidewall suit seam of flow straightener corroded aggravation, after the continuous casting trough casting 13 to 15 hours, suit sews to corrode and penetrates, cause being set with inner core floating, shell does not just have impact and the erosion of enough intensity opposing steel stream, and the shell cracking loses current stabilization and promotes the inclusion floating effect, so that the tundish impact area bottom temp greater than 300 ℃ and wear the bag accident, does not satisfy the needs of production service life.Leading reason is that the clay filled thing of the suit inner core seam of sleeve type flow straightener is easily washed away erosion by steel stream, molten steel just penetrates in the seam and to have come up inner core is floating, shell can not bear again the erosion of washing away of steel stream, flow straightener just is forced to damage and scraps, lose the effect of flow straightener, not only can not satisfy large-scale production, also cause the waste of resource.
Therefore, produce a kind of simple in structure, simple to operate, long service life, high efficiency, the composite continuous casting tundish current stabilizer of overall structure firm stable has wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the composite continuous casting tundish current stabilizer of a kind of simple in structure, simple to operate, long service life, high efficiency, overall structure firm stable.
The technical solution of the utility model is achieved in that a kind of composite continuous casting tundish current stabilizer, comprise body, be opened in the notch on the body, the described notch below that is opened on the body is provided with the base plate holddown groove, in the base plate holddown groove base plate is installed, base plate and body are structure as a whole.
Described notch and base plate holddown groove are circular trough shape structure, and the internal diameter of notch is less than the internal diameter of base plate holddown groove.
Described base plate adopts magnesium carbonaceous mechanical pressing, and body adopts the vibration moulding of steel fibre alumina-magnesia castable.
The utlity model has following good effect: at first, this production operation is simple and easy to control, and overall performance is excellent, does not have the waste product flaw; Secondly, this product anti-erosion resistance to erosion ability increases substantially, and former flow straightener only is 13 to 15 hours in the duration of pouring of continuous casting tundish, uses this product can reach more than 40 hours, improves twice service life; Again, prior art products was continuous casting basket pouring 13 to 15 hours, occur repeatedly that the flow straightener inner core is floating, the bottom penetrates and cause wear bag and the unplanned accident of watering of stopping, using the utility model product to connect at single tundish watered in 72 hours, the problems referred to above do not appear, reach 75 hours 52 minutes service life the highest, security reliability is high; The utility model product is applicable to all kinds of continuous casting tundish, can increase substantially tundish service life, reduces the continuous casting refractory consumption, remarkable in economical benefits.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model notch and base plate fixed slot configurations schematic diagram.
The specific embodiment
As shown in Figure 1, 2, a kind of composite continuous casting tundish current stabilizer comprises body 1, is opened in the notch 4 on the body 1, and described notch 4 belows that are opened on the body 1 are provided with base plate holddown groove 3, base plate 2 is installed in the base plate holddown groove 3, and base plate 2 is structure as a whole with body 1.
Described notch 4 and base plate holddown groove 3 are circular trough shape structure, and the internal diameter of notch 4 is less than the internal diameter of base plate holddown groove 3.Described base plate 2 adopts magnesium carbonaceous mechanical pressing, and body 1 adopts the vibration moulding of steel fibre alumina-magnesia castable.
The utility model adopts monoblock type composite structure, base plate 2 adopts magnesium carbonaceous mechanical pressing goods, body 1 adopts the vibration moulding of steel fibre alumina-magnesia castable to form, and just after the bottom installs magnesium carbon goods base plate 2, direct combination is shaped to one during body 1 moulding.
