Abstract
The utility model discloses a steel ladle with a rotatable blowing position at the bottom part. The steel ladle comprises an air permeable brick, a fixed device, a rotary ring, a furnace body at the bottom part of the steel ladle, a gear, a rotary shaft, a steel outlet, a motor, a disc and threads, wherein the rotary ring 3 is embedded at the bottom part of the steel ladle; the disc is arranged at the middle part of the rotary ring; the air permeable brick is arranged in the rotary ring; the rotary ring and the disc are fixed on the furnace body at the bottom part of the steel ladle by the fixed device through bolts; the threads are engraved at the bottom part of the rotary ring, and the rotary ring is meshed with the gear and is driven to rotate by the motor through the rotary shaft; and the steel outlet is arranged on the furnace body at the bottom part of the steel ladle. The steel ladle disclosed by the utility model has the advantages that the change of the blowing position is realized by enabling the motor to drive the ring to rotate, and the need for change of the blowing position at different periods of refining is met. The steel ladle has the characteristic that the optimal blowing position is adjusted according to different blowing amounts, so that the refining efficiency and the quality of molten steel are improved.
Description
Technical field
The utility model relates to the ferrous metallurgical industry refining equipment, particularly the rotary steel ladle in a kind of bottom blowing position.
Background technology
In the Ferrous Metallurgy refinery practice, normally build the one or a few blocks air brick at cast ladle or brick ladle bottom, be blown into gas by air brick after the tapping, cause the stirring of molten steel in the ladle.The floating that air blowing can promote that the emulsification slag drips, be mingled with in the steel can partly be removed and is dissolved in the gas in the steel and makes molten steel component even, and in cooperating the continuous casting occasion, ladle is blown and can be played the effect of adjusting molten steel temperature.It is a kind of important process for making process that ladle is blown, and existing ladle blow-out position all is positioned at the ladle bottom center, and its blow-out position is fixed.
If the position that single hole is blown is near the ladle center; stable ladle internal turbulence will be centered by injection hole, forms the numerous symmetrical turbulent flow group who radially distributes, and its movement locus is basic identical; mixability is basically identical, so mixed effect is also best.When injection hole more departs from the center, turbulent flow is more disorderly flowing of ladle inside, rambling turbulent flow so that inner liquid flow mutually hinder, kinetic equation loss, the effect of therefore mixing is wanted variation, consider that blowing argon gas to gas and other effect in molten steel removal of inclusions, the removal molten steel, if can regulate as required at any time blow-out position in whole refining process, will all increase to molten steel quality and efficient so.
Consult the correlation technique document, Chinese patent " a kind of steel ladle of refractory material prefabricated components lining ", open (bulletin) number: CN2127048, this steel ladle is comprised of iron shell, gudgeon, support, the mouth of a river, gate mechanism and refractory lining.The steel ladle permanent layer is integrated poured body, and the bag oral area of working lining is divided into refractory brick marshalling, and wall section is annular fireproofing prefabricated member bond body, and the bottom is that the seam crossing of prefabricated component bonds with refractory adhesive with integral prefabricated of the cheese in a pocket block hole.Dose fire-resistant inserts between permanent layer and the working lining.This molten steel ladle inner lining seam is few, and long service life adopts prefabricate, but quick-assembling, baking during use, not only turnover is fast, efficient is high, and unpacks easily, has improved working condition, has reduced production cost.But its blow-out position is changeless, can not change blow-out position at the needs according to different refining period.
Chinese patent " a kind of steel ladle ", open (notification number): CN2153424, relate to a kind of Sheng steel in water container, comprise involucrum, cylinder-packing, bag edge, the involucrum cross section that is provided with suitable for reading is the steel ladle edge of " ┒ " shape, the inwall on steel ladle edge and steel ladle profile suitable for reading is complementary, and cylinder-packing and involucrum that its upper surface is suitable for reading with steel ladle cover, steel ladle along with involucrum between connected by retention mechanism.This steel ladle has simple in structure, for ease of maintenaince, the advantage that non-deformability is strong, but blow-out position is not optimized design, not reaching air-blowing quantity does not need to change the condition of blow-out position simultaneously, can better not give security for improving refining efficiency and molten steel quality.
Summary of the invention
The utility model provides a kind of bottom blowing position rotary steel ladle, Effective Raise refining efficiency and molten steel quality.
The utility model provides the rotary steel ladle in a kind of bottom blowing position to comprise: air brick, fixture, tumbler ring, steel ladle bottom body of heater, gear, turning cylinder, tapping hole, motor, disk and screw thread, tumbler ring 3 is embedded in the steel ladle bottom, be provided with disk in the middle of the tumbler ring, air brick is located in the tumbler ring, tumbler ring and disk are bolted on the body of heater of steel ladle bottom by fixture, screw thread is carved with in the tumbler ring bottom, mesh with gear, rotated by Motor Drive by turning cylinder, tapping hole is located on the body of heater of steel ladle bottom.
The utility model is compared with existing same device, and its beneficial effect is embodied in:
Rotate to realize the variation of blow-out position by the motor drives annulus, satisfy the demand that refining different times blow-out position changes, have the advantages that to adjust best blow-out position according to different air-blowing quantities, thereby improve the efficient of refining and the quality of molten steel.
Description of drawings
Fig. 1 is the rotary steel ladle structural representation in a kind of bottom blowing position.
Fig. 2 is a kind of bottom blowing position rotary steel ladle A face generalized section.
Fig. 3 is tumbler ring generalized section in the rotary steel ladle in a kind of bottom blowing position.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the rotary steel ladle in a kind of bottom blowing position is by air brick 1, fixture 2, tumbler ring 3, steel ladle bottom body of heater 4, gear 5, turning cylinder 6, tapping hole 7, motor 8, disk 9 and screw thread 10 consist of, tumbler ring 3 is embedded in the steel ladle bottom, be provided with disk 9 in the middle of the tumbler ring, air brick 1 is located in the tumbler ring 3, tumbler ring 3 and disk 9 are bolted on the body of heater 4 of steel ladle bottom by fixture 2, screw thread 10 is carved with in the tumbler ring bottom, with gear 5 engagements, drive rotation by turning cylinder 6 by motor 8, tapping hole 7 is located on the body of heater 4 of steel ladle bottom.
Wherein the steel ladle diameter is 3m, the tumbler ring diameter be 1.5m, width be 0.3m, highly for 0.3m.
