Further, it is equipped with for taking the position of the tipping table 21 for buffering tipping table time on support frame as described above 23
The cushion 27 of impact force when falling.As shown in figures 1 and 3, by setting cushion 27 on support frame 23, for working as tipping table 21
Buffering when falling to horizontal operation position, avoids impacting.
Further, one end on the vehicle frame 22 far from support frame as described above 23 is equipped with fixed frame, and the fixed frame is logical
It crosses rotary hinge axis 24 and the tipping table 21 is hinged.As shown in figures 1 and 3, one end of tipping table 21 by rotation hinged shaft 24 with
Vehicle frame 22 is connected, and rotates tipping table 21 around rotation hinged shaft 24, to realize that tumbling for hot-metal bottle 1 is skimmed.
Further, the tilting mechanism includes telescopic oil cylinder 28, and the telescopic oil cylinder 28 includes cylinder body and piston rod,
The cylinder body and the vehicle frame 22 are hinged, and the extension end of the piston rod and the tipping table 21 are hinged.As shown in Figure 1, flexible
The side of support frame 23 is arranged in oil cylinder 28, and telescopic oil cylinder 28 is mounted on vehicle frame 22 with the hinged installation form in cylinder body tail portion, is stretched
The extension end on the head of contracting oil cylinder 28 is mounted on the lower surface of tipping table 21, and piston rod can drive tipping table 21 around rotation when stretching out
The rotation of turning hinge axis 24 is tumbled to realize, so that hot-metal bottle 1 is made to reach position of skimming, as shown in figure 3, when tumbling, telescopic oil cylinder 28
Piston rod slowly stretches out, and according to the needs for angle of tumbling, stroke is stretched out in adjustment；When reset, the piston rod of telescopic oil cylinder 28 is slowly
It retracts, until being fully retracted into.Telescopic oil cylinder 28 is multi-joint telescoping form in the present embodiment, after this structure retracts original length compared with
It is small, it not only can reduce the overall height of hot-metal ladle and carriage 2, but also be able to satisfy the range demand for tumbling required.
Further, the position for the hot-metal bottle 1 being corresponded on the tipping table 21 is equipped with several rotary EMS devices
25, circumferencial direction equidistantly distributed of several rotary EMS devices 25 along the hot-metal bottle 1.Rotating electromagnetic stirs in the present embodiment
Mixing device 25 is a kind of horizontal rotation electromagnetic stirring system, its principle is that rotary magnetic is generated between magnetic pole after leading to three-phase alternating current
, rotating excitation field generates induced current in molten iron, and then turning moment is generated in molten iron, and molten iron is made to generate rotary motion.
The blender is mounted on inside tipping table 21, is not influenced the lifting of hot-metal bottle 1 and is tumbled.
Further, the bottom of the vehicle frame 22 is equipped with wheel group 29.As shown in figures 1 and 3,22 bottom of vehicle frame is pacified
Four pairs of wheel groups 29 are filled, for carrying and transporting hot-metal bottle, hot-metal bottle 1 is transported to desulfurization working position.
The working principle of Desulfuring Device of Hot Metal provided in this embodiment:
The hot-metal bottle 1 for filling molten iron is located on hot-metal ladle and carriage 2, is transported to desulfurization working position by hot-metal ladle and carriage 2, is then sprayed
Rifle 3 drops in hot-metal bottle 1, and desulfurizing agent is sprayed into hot metal interior, carries out desulfurizing iron operation；When desulfurizing agent sprays into molten iron
When, since the density of desulfurizing agent is lower than molten iron density, desulfurizing agent meeting floating upward quickly causes to react insufficient；In order to improve desulfurization
Efficiency and increase blowing intensity, will cause molten iron splash, bring very detrimental effect；
The present embodiment is not increasing mechanical stirring equipment, is not improving blowing intensity to improve the efficiency of blowing desulfurization
Under the premise of, improve the dynamic conditions of molten iron using electromagnetic agitation, improves the reaction efficiency of molten iron and desulfurizing agent.Desulfurizing iron dress
When setting in working position, as shown in Figure 1, spray gun 3 drops in hot-metal bottle 1 after certain depth, carrier gas (inert gas) is by desulfurization
Hollow pipeline of the agent inside spray gun 3 is delivered in molten iron, the power supply of rotary EMS device 25 is then connected, in hot-metal bottle 1
Interior molten iron bottom generates induced current, and then molten iron in the region is made to generate turning moment, so that molten iron is generated rotary motion, stirs
The molten iron of dynamic molten iron pot bottom improves the reaction efficiency of molten iron and desulfurizing agent, and band so as to improve the dynamic conditions of molten iron
The desulfurizing agent on dynamic top sinks, and further increases the utilization rate of desulfurizing agent；Before blowing terminates, rotary EMS device 25 is first disconnected
Power supply, stop electromagnetic agitation, then stop being blown again, promoted spray gun 3, terminate desulfurization operations；
After blowing desulfurization, need to carry out the slag inside hot-metal bottle 1 to take off slag operation.Since the density of slag is lower than molten iron
Density, it can swim in molten iron surface, need certain angle that hot-metal bottle 1 is tumbled, and set as shown in Fig. 3, then with special skim
It is standby that slag is grilled into slag ladle, hot-metal bottle 1 is then restored into horizontal position again, is transported by hot-metal ladle and carriage 2.It tumbles the drive of movement
Dynamic to be completed by telescopic oil cylinder 28, when tumbling, the piston rod of telescopic oil cylinder 28 slowly stretches out, according to the needs for angle of tumbling, adjustment
Stretch out stroke；When reset, the piston rod of telescopic oil cylinder 28 is slowly retracted, until being fully retracted into, tipping table 21 is slowly located at this time
It onto support frame 23, and can be buffered by cushion 27, avoid impacting；Needed for telescopic oil cylinder 28 can satisfy and tumble
Larger stroke demand, original length is smaller after retraction, can reduce the total height of hot-metal ladle and carriage 2.When hot-metal bottle 1 is with tipping table
21 when tumbling, and hot-metal bottle 1 shakes in order to prevent, guide limiting stopper 26 is provided with, for limiting the shaking of hot-metal bottle 1.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
