Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Fig. 1～shown in Figure 4, the utility model elevated pressure nitrogen source of the gas is leaded up to stopping valve 1 and is linked to each other with check valve 3, and check valve 3 is connected with the inlet of high-voltage large-capacity gas-holder 5; Another road of high pressure nitrogen is connected with check valve 4 by stopping valve 2, and check valve 4 links to each other with the outlet of high-voltage large-capacity nitrogen filling 5.High-voltage large-capacity nitrogen is irritated 5 export pipelines and be divided into four pipelines in pneumatic pressure reducing station 23, after accumulate two pipelines again: one is connected with stopping valve 7, high-pressure high-flow relief valve 8 by stopping valve 6, check valve 9 is installed on the outlet of stopping valve 7 and high-pressure high-flow relief valve 8 pipelines, and is pooled to jet main line 24; Article one, by stopping valve 10 be divided into two pipelines after stopping valve 18, high-pressure high-flow relief valve 11 link to each other: one links to each other with high-pressure high-flow relief valve 19 by stopping valve 18, and passes through check valve 20, and its outlet comes together in jet main line 24; Article one, link to each other with gas control ball valve 12 by high-pressure high-flow relief valve 11, and come together in jet main line 24 by check valve 14 outlets; After the last item passed through stopping valve 15 and high-pressure high-flow relief valve 17 is connected, cylinder pilot piping 16 was led in the pipeline outlet.Medium capacity gas-holder 21 leads to jet main line 24 with after stopping valve 22 is connected.Jet main line 24 links to each other with pneumatic ball valve 25, and swivel joint 33 is led in outlet; Cylinder pilot piping 16 connects pneumatic ball valve 26 and 27, and swivel joint 33 is led in outlet; Cooling gas leads to swivel joint 33 by strainer 29, the first low pressure regulating pressure valves 30.Have 4 road gases to be pooled to swivel joint 33 after the gas control cabinet comes out, be respectively: 24 gases are responsible in one tunnel pushing off the slag; Two-way cylinder pilot-gas; One tunnel low pressure cooling gas.Pushing off the slag is responsible for gas and is directly connected to pushing off the slag cantilever 36 device places after by swivel joint 33, and pushing off the slag 37 directly is installed on the top of pushing off the slag cantilever 36, and high pressure draft from pushing off the slag 37 ejection, is used to stop that slag enters ladle through pushing off the slag cantilever 36.Another road pilot-gas is directly connected to the rod chamber and the rodless cavity of a pushing off the slag cylinder 38 by behind the swivel joint 33, is used to control the forward-reverse of pushing off the slag head.During pushing off the slag 37 work, a pushing off the slag cylinder 38 promotes cantilevers and nozzle carries out mechanical close to tap hole, and chock plug end inject high pressure gas prevents that slag from flowing out.The low pressure cooling gas directly leads to pushing off the slag head unit 34 by swivel joint.
As shown in Figure 3, article one, high pressure nitrogen is by being divided into four pipelines in pressure reducing station, after accumulate two pipelines again: one is connected with stopping valve 7, relief valve 8 by stopping valve 6, and check valve 9 is installed on the outlet of stopping valve 7 and relief valve 8 pipelines, and is pooled to jet main line 24; Article one, by stopping valve 10 be divided into two pipelines after stopping valve 18, relief valve 11 link to each other: one links to each other with relief valve 19 by stopping valve 18, and passes through check valve 20, and its outlet comes together in jet main line 24; Article one, link to each other with gas control ball valve 12 by relief valve 11, and come together in jet main line 24 by check valve 14 outlets; After the last item passed through stopping valve 15 and relief valve 17 is connected, cylinder pilot piping 16 was led in the pipeline outlet.An other low pressure line is used to provide the motivating force of high-pressure ball valve topworks, and can control by magnetic valve 13 and drive ball valve 12 topworkies, thus the switch of control ball valve 12, thus reach the effect of pressure regulation.
The slag-blocking apparatus algorithm: control magnetic valve 28 advance side get electric, and pneumatic ball valve 27,40 is opened, and cylinder pilot piping 16 mesohigh nitrogen lead to a pushing off the slag cylinder 38 rodless cavities by swivel joint 33, promote pushing off the slag cantilever 36 and pushing off the slag 37 a past tap hole motion; Controlling in the pneumatic pressure reducing station 23 first magnetic valve 13 simultaneously opens, make high pressure gas arrive pneumatic ball valve 25 by pneumatic pressure reducing station with pressure one, when magnetic valve 28 is opened, pneumatic ball valve 25 is also opened simultaneously, high pressure gas are by behind the pneumatic ball valve 25 like this, again by swivel joint 33, pushing off the slag cantilever 36 is ejection from pushing off the slag 37, thereby blocking slag flows out from tap hole, pressure meeting this moment autostable is closed magnetic valve 13 at pressure two after blowing slag open, high pressure draft is with pressure two, continue winding-up, converter simultaneously begins to rotate makes tap hole leave lowest order; When the slag liquid level leaves tap hole, control magnetic valve 28 retreats side and gets, the advance side dead electricity, cylinder pilot piping 16 mesohigh nitrogen lead to a pushing off the slag cylinder 38 rod chambers by swivel joint 33, promote pushing off the slag cantilever 37 and pushing off the slag nozzle 36 and return starting position, close pneumatic ball valve 25,27 simultaneously, 40; Finish the one action process.
The stressing conditions of pushing off the slag Controlling System during according to pushing off the slag, pressure is divided into three phases, when chock plug has just arrived the tap hole position, need bigger pressure, slag is barred from the converter by air-flow, guarantee that simultaneously nozzle and cantilever can not shine into damage, be stabilized in another pressure after slag is blown open, after converter taphole rotated to certain angle along with converter, slag left tap hole, the pushing off the slag head need in time be got back to starting position, and stops the winding-up of pushing off the slag air-flow.So promptly can improve the working efficiency of equipment, also can reduce the damage of air-flow, reach best pushing off the slag effect converter taphole.
With reference to accompanying drawing, provide the foregoing description.To help to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
