Description
Technical field
The utility model relates to steel-making machinery, relates in particular to the mechanism of additional control metal liquid flow on the converter taphole.
Background technology
After converter steelmaking finishes, need molten steel is poured in the ladle through the converter taphole outflow.Because the slag proportion that produces during steel-making is less than molten steel, so slag floats on the molten steel.And converter tapping adopts is the Dumpage type tapping, and therefore in the initial stage of tapping, the slag that floats on above the molten steel will flow out (this stage, effusive slag was called pre-slag) from tap hole prior to molten steel.When molten steel has soon flowed, because of also being mingled in the molten steel, the eddying effect slag together flows out (this stage, effusive slag was called the later stage slag), tap like untimely stopping, will there be a large amount of slags to flow in the ladle.Slag can influence steel quality in molten steel, thereby increases back operation processing cost.Flow in the ladle for reducing slag; That generally adopts at present has devices such as slag-blocking ball, floating plug; These devices can't block pre-slag, and along with the increase of converter steelmaking number of times, tap hole steel hole present situation will become irregular; The pushing off the slag success ratio of slag-blocking ball, floating plug will descend, and the later stage slag quantity of slag that gets into ladle increases.
Summary of the invention
The utility model problem to be solved provides a kind of pushing off the slag gate valve mechanism that is arranged on the converter taphole, and through the dislocation of can sliding of two slide bricks with holes, the switch tap hole is realized the pushing off the slag tapping.Pre-slag, control later stage slag can block in this mechanism, and pushing off the slag control slag is respond well, satisfies the requirement of converter less-slag tapping.
A kind of converter taphole pushing off the slag of the utility model gate valve mechanism is characterized in that: it comprises fixed glides brick and the sliding skateboard brick of fixed frame, switch frame, slider bar, middle perforate, outer nozzle brick, outer mouth of a river fixed frame, outer mouth of a river installing frame; Fixed frame, switch frame are provided with from top to bottom; And be connected through bearing pin; Slider bar is arranged in the switch frame, and the fixed glides brick is fixed in the fixed frame, and sliding skateboard brick, outer nozzle brick are fixed in the slider bar from top to bottom; The top and bottom of sliding skateboard brick contact with fixed glides brick, outer nozzle brick respectively; Rail plate on the slider bar lower surface contacts with fixed guide on the switch frame upper surface, the switch frame and outside be provided with the outer mouth of a river installing frame that is fixed on the slider bar between the nozzle brick, be provided with outer mouth of a river fixed frame between the external diameter recess of mouth of a river installing frame and outer nozzle brick bottom outside.
The mechanism of the utility model is fixed on fixed frame on the converter taphole through swing bolt.In-house fixed glides brick and sliding skateboard brick be separately fixed in the fixed frame with slider bar in, be plane contact between two slide bricks, contact through guide rail between slider bar and the switch frame.The drive unit that links to each other with slider bar promotes slider bar and in the switch frame, moves back and forth; Thereby drive the motion of sliding skateboard brick; Realize concentric or the dislocation of the circular hole on sliding skateboard brick and the fixed glides brick, make mechanism be in unlatching or closing condition, be used for molten steel or slag outflow are controlled.

Embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, can find out; A kind of converter taphole pushing off the slag of the utility model gate valve mechanism, it comprises fixed glides brick 4 and sliding skateboard brick 5, outer nozzle brick 6, outer mouth of a river fixed frame 7, the outer mouth of a river installing frame 8 of fixed frame 1, switch frame 2, slider bar 3, middle perforate; Fixed frame 1, switch frame 2 are provided with from top to bottom; And be connected through bearing pin; Slider bar 3 is arranged in the switch frame 2, and fixed glides brick 4 is fixed in the fixed frame 1, and sliding skateboard brick 5, outer nozzle brick 6 are fixed in the slider bar 3 from top to bottom; The top and bottom of sliding skateboard brick 5 contact with fixed glides brick 4, outer nozzle brick 6 respectively; Rail plate 10 on slider bar 3 lower surfaces contacts with fixed guide 9 on switch frame 2 upper surfaces, switch frame 2 and outside be provided with the outer mouth of a river installing frame 7 that is fixed on the slider bar 3 between the nozzle brick 6, be provided with outer mouth of a river fixed frame 8 between the external diameter recess of mouth of a river installing frame 7 and outer nozzle brick 6 bottoms outside.
For fixed glides brick 4 and sliding skateboard brick 5 can be pressed together better; As this novel a kind of optimal way; The both sides, front and back of switch frame 2 are provided with holddown: holddown comprises spring 11, spring bearer plate 12, face pressure bolt 13, and the lower surface of switch frame 2 is processed with cavity, is placed with spring 11 in the cavity; Spring bearer plate 12 is pressed on spring 11 in the cavity; Face presses bolt 13 to be connected in the nut sleeve 15 that is welded on the fixed frame 1 through spring bearer plate 12, thereby generation face pressure is pressed together fixed glides brick 4 and sliding skateboard brick 5.Press bolt 13 to screw in the nut sleeve 15 face to face; Through spring bearer plate 12 compression springs 11; Produce pressure; Through switch frame 2, fixed guide 9, rail plate 10, slider bar 3 sliding skateboard brick 5 is fitted tightly on fixed glides brick 4, thereby generation face pressure guarantees good sealing property between two slide bricks.
As this another novel optimal way, outer mouth of a river fixed frame 8 is pressed on outer nozzle brick 6 through standing bolt 14 with sliding skateboard brick 5.
Slide brick jumps in die cavity when preventing organization switch, and a side of fixed frame 1, slider bar 3 is provided with holding device 16, and fixed glides brick 4 and sliding skateboard brick 5 are held out against in fixed frame 1, slider bar 3.
The mechanism of the utility model is fixed on fixed frame 1 on the converter taphole through swing bolt.In-house fixed glides brick 4 and sliding skateboard brick 5 be separately fixed on the fixed frame 1 with slider bar 3 on, two slide bricks 4, be plane contact between 5.Contact through rail plate 10, fixed guide 9 between slider bar 3 and the switch frame 2.Drive unit 17 promotes slider bar 3 and in switch frame 2, moves back and forth; Thereby drive 5 motions of sliding skateboard brick; Realize on sliding skateboard brick 5 and the fixed glides brick the concentric or dislocation of 4 circular hole, make mechanism be in unlatching or closing condition, be used for molten steel or slag outflow are controlled.
The state of the concrete work of mechanism is: before after steel-making finishes, preparing tapping; Before converter is poured into the slag tapping passage that floats on the molten steel; Drive unit 17 work that link to each other with slider bar 3; Promote slider bar 3 and in switch frame 2, move, make the circular hole dislocation on sliding skateboard brick 5 and the fixed glides brick 4, make mechanism be in closing condition.At this moment topple over converter; After molten steel covers the tapping passage fully; Drive unit 17 is task again, promote slider bar 3 in switch frame 2, move (with the first time travel direction opposite), make sliding skateboard brick 5 concentric with the circular hole on the fixed glides brick 4; Make mechanism be in full-gear, let molten steel flow out and get in the ladle.When the fast end of tapping; When being blended in molten steel and will flowing out together because of the eddying effect slag, drive unit 17 work again, promote slider bar 3 in switch frame 2, move (with the first time travel direction identical); Make the circular hole dislocation on sliding skateboard brick 5 and the fixed glides brick 4; Make mechanism be in closing condition once more, promptly close the tapping passage rapidly, thereby finish tapping.Through such operation, can block pre-slag fully, control later stage slag reaches and reduces the effect that slag gets into ladle.
