Description
Technical field
The utility model relates to a kind of metallurgical equipment that uses in metallurgy industry, especially a kind of molten metal external refining final deoxygenation that is used for, and trimming goes the insert feeding wire machine that is mingled with.
Background technology
Present molten steel external refining process is to the adjustment of trace element in the molten steel, normally utilize wire-feeding technique will approach in the alloy wire or cored-wire feeding molten steel that steel band coats mixtures such as certain granular or powdered calcium metal, silicon, aluminium, this method can significantly reduce oxygen in the molten steel, sulphur content, improve the purity of molten steel, change inclusion morphology, thereby improve the quality and the performance of steel casting.Traditional line feeding method is that feeding wire machine is installed on the dolly, and dolly can move forward and backward is in orbit waiting for that position or working position stop.After the molten steel of need processing hung the refining furnace working position from the coverter pig crane, when carrying out the alloying constituent fine setting according to the molten steel sampling result, feeding wire machine reached the working position line feeding, and line feeding stops after calculating the rice number.After liquid steel refining is finished, move on to after the feeding wire machine and wait for that the position stops, and waits for that next stove purified begins.
During with this line feeding method line feeding, because line feeding conduit outlet and liquid steel level distance are far away, add the thicker slag blanket of high temperature and surface of molten steel, under the certain situation of cored-wire line sending speed, alloy wire or cored-wire are from the degree of depth that the liquid steel level slag blanket penetrates molten steel very little (generally can only to 300---500mm under the liquid level).If the molten steel storage period is long, molten steel surface temperature is lower, in the cored-wire molten steel more difficult to get access, coils sometimes on the molten steel face.In the ordinary course of things, because that alloy wire enters the molten steel degree of depth is not enough, alloy part becomes gaseous state to be present in to be easy in the steel overflow molten steel to enter atmosphere, causes that alloy recovery is low, cost is high, and easily causes environmental pollution.

Embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described further.
Referring to Fig. 1 and Fig. 2, the utility model insert feeding wire machine is provided with service platform, is fixed with support 1 and hoistway 2 on the service platform.Support 1 is stable rigid structure, and the crossbeam 3 that moves along slideway is installed on the hoistway 2; The drive unit 4 that motor and speed reducer is formed also is installed on the service platform, a rope drum 5 is installed in the rotating shaft of drive unit 4, twine steel cable 6 on the rope drum 5.Drive unit 4 can positive and negatively rotate, and drives steel cable 6 folding and unfoldings on the rope drum 5.Steel cable 6 connects crossbeam 3 by the pulley set 7 that is installed in a top of the trellis, drives crossbeam 3 liftings.Pulley set 7 is leading sheaves of steel cable 6.Hung counterweight 16 7 times in pulley set, when hoisting cross beam 3, counterweight 16 plays the effect of the power that reduces drive unit 4, and is complementary with gross weights such as crossbeam 3, line feeding case 8, line feeding rifles 11, reaches equilibrium of forces when crossbeam 3 liftings.Crossbeam 3 one ends are line feeding case 8 fixedly, and line feeding case 8 is provided with incoming line and line outlet; Crossbeam 3 the other ends are fixed with cylinder 9, and cylinder 9 is a kind of general commercially available prod, and what its flexible work control was all used is prior art, and as model S125 * 300, standard is the cylinder of JB1448-74.One end of the connecting rod of cylinder 9 and arm-tie 10 is connected; The other end of arm-tie 10 connects line feeding rifle 11.Also have a cored-wire volume 12 on service platform, cored-wire 13 is made by the special manufacturer, is used to steelworks production service, coils about general 3000--5000 rice and rolls up.Cored-wire 13 is from entering the incoming line of line feeding case 8 after cored-wire volume 12 is extracted out.Line feeding case 8 is the existing universal product of the industry, and cored-wire 13 is drawn to the line outlet of line feeding case 8 by the electric motor in the line feeding case 8.Line outlet at line feeding case 8 is connected with line feeding conduit 14, and line feeding conduit 14 is fixed on the crossbeam 3.Cored-wire 13 enters line feeding conduit 14 after the line outlet of line feeding case comes out, being provided with of this line feeding conduit 14 limited the movement locus of cored-wire 13 between line feeding case 8 and line feeding rifle 11.The incoming line that line outlet and the line feeding conduit 14 of cored-wire 13 by line feeding case 8 enters line feeding rifle 11 stretches out from the line feeding rifle head 15 of line feeding rifle 11.The body of a gun structure of line feeding rifle 11 is interior to be carbon steel pipe, is outward the clay refractory materials.Body of a gun upper end at line feeding rifle 11 also is provided with nitrogen tube 17, with delivering gas in line feeding rifle 11.At the incoming line place of line feeding rifle 11 vacuum breaker is installed, can only outwards carries from the rifle head of line feeding rifle 11 to guarantee nitrogen.
Referring to Fig. 3 working process of the present utility model is described.Be in when treating working order at the utility model, crossbeam 3 is parked in the limes superiors position, and line feeding rifle 11 is in plumbness under the effect of cylinder 9.The utility model is started working after the ladle 18 usefulness cranes that fill molten steel hang the refining furnace working position.Drive unit 4 driving rope drums 5 were rotated in the forward before this, and steel cable 6 drives counterweights 16 by pulley set 7 and rises, and the crossbeam 3 that be fixed with line feeding case 8, line feeding conduit 14 and cylinder 9 this moment moves downward predeterminated position along hoistway 2.At this moment, cylinder 9 work make line feeding rifle 11 swing to predetermined angle by arm-tie 10.When the rifle head 15 of line feeding rifle 11 during near the liquid steel level of ladle 18, nitrogen is fed in the line feeding rifle 11 by nitrogen tube 17, and the main effect of nitrogen is to stop steel or slag liquid to enter the rifle hole to cause stifled rifle.At this moment line feeding rifle 11 continues to move downward and enters into predetermined position in the molten steel, and simultaneously, the motor start-up of line feeding case 8 begins to feed cored-wire 13.
When the cored-wire 13 of feeding was near computational length in the molten steel, the electric motor of drive unit 4 was through 5 reverse rotations of step-down gear deceleration rear drive rope drum, and crossbeam 3 moved upward along hoistway 2 when steel cable 6 drove counterweight 16 declines by pulley set 7.After the rifle head 15 of line feeding rifle 11 breaks away from liquid steel level, the valve closes of nitrogen tube 17, the electric motor of line feeding case 8 shuts down.When treating that crossbeam 3 rises to limit position, the electric motor of drive unit 4 shuts down, and the control unit of cylinder 9 drives cylinder 9 and gets back to the vertical position by arm-tie 10 promotion line feeding rifles 11, finishes the fine setting to molten steel composition, waits for that next stove molten steel puts in place.
