Description
Technical field
This utility model relates to a kind of steelmaking equipment, particularly relates to the air-cooled structure on a kind of pneumatic steelmaking skimming device, and converter slag-resisting mechanism can be cooled down by well, it is ensured that its service life.
Background technology
In pneumatic steelmaking, slag damming mechanism is arranged on tapping hole, and when tapping, mechanism is positioned at the surface of ladle, especially taps the later stage, molten steel structure of disembarking at about 1 meter, even less than 80 centimetres had.And mechanism body and internal crucial flexible member and refractory material are by hyperthermia radiation, temperature-measuring gun observed temperature is up to about 500 DEG C.Slag damming mechanism the most each parts mechanical performance has declined, and the life-span is shorter.In order to allow slag damming mechanism lower the temperature and steady operation, technical staff devises air cooling system, applies in converter slag-resisting mechanism.Converter slag-resisting mechanism air cooling system has two kinds of versions at present: 1. as it is shown in figure 1, i.e. wind outside low-temperature receiver is directly connected with tension assembly, and cooling gas enters from one end of spring cavity, reaches the other end by stream pressure, to realize the cooling of equipment；The most as shown in Figure 2, i.e. by offering air-cooled passage and reserve air port in connection component body, and be connected with the air inlet of mounting assembly, it is connected to tension assembly air inlet finally by U-shaped forced air cooled tube, cooling gas enters from one end of spring cavity, the other end is reached, to realize the cooling of equipment by stream pressure.
Above two air cooling way has the disadvantage in that two kinds of cooling structures shown in (1) Fig. 1 and Fig. 2, air-cooled source is all that one end of spring cavity from tension assembly enters the other end outflow from spring cavity, so, the pressure of compressed air of the arrival spring cavity other end is not and flow velocity diminishes, and therefore arrives the cooling effect extreme difference during spring cavity other end；(2) when changing the slag damming mechanism of air-cooled structure shown in Fig. 1 online: first the forced air cooled tube 21 of the air intake in converter is dismantled with slag damming mechanism junction spanner, need also exist for loading onto during online installation, and the temperature of tapping hole position can reach 300 DEG C at the end of steel is put in converter, so workmen is easy to be burned, and so engineering time is longer；(3), during the refractory brick 23 in off-line changes the slag damming mechanism of air-cooled structure shown in Fig. 2, U-shaped forced air cooled tube 22 to be removed and could be changed, also to install after replacing, the most time-consuming；(4) both the above air-cooled structure, under conditions of pneumatic steelmaking many slags high temperature, exposed airduct and joint are fragile, and air cooling effect is poor, and air cooling system instream factor is the highest.
Utility model content
Problem to be solved in the utility model is to provide a kind of high-efficiency air cooling structure of converter slag-resisting mechanism, and it can realize the cooling of converter slag-resisting mechanism well, it is ensured that the effect of cooling, extends the service life of converter slag-resisting mechanism, thus cost-effective.Meanwhile, this utility model both ensure that the personal safety of workmen, can shorten the engineering time again, drastically increase work efficiency.
The high-efficiency air cooling structure of this utility model converter slag-resisting mechanism, it includes connecting component body, mounting assembly body, tension assembly；The two ends, left and right connecting component body are each provided with an air inlet symmetrically, are symmetrically each provided with two air outlets above it, and each air inlet passes through upper and lower two air outlets of air-cooled channel connection；It is provided with four installing holes, welded nut seat in installing hole on the position that mounting assembly body is corresponding with four air outlets connecting component body；Tension assembly includes tension assembly body, flexible member, compression panel, tensioning bolt, on tension assembly body, left and right is symmetrically provided with blind slot, a venthole is respectively offered at the two ends up and down of each blind slot, blind slot is provided with flexible member, two, left and right compresses panel and is placed on flexible member, two, left and right compresses and is each provided with two through holes on panel, the bottom of each blind slot is provided with two through holes, compresses the through hole bottom through hole on panel and blind slot, nut seat installing hole three on mounting assembly body coaxial；Up there is a blind hole at the center of tensioning bolt from bottom, is provided with two side openings communicated with blind hole with blind hole vertical direction in the end close to blind hole；Tensioning bolt sequentially passes through the compression through hole of panel, the through hole of blind slot from top to bottom, threadeds with nut seat, makes compression panel be pressed in blind slot by flexible member, is in close contact between tension assembly body and mounting assembly body.
In converter slag-resisting mechanism, when using high-efficiency air cooling structure of the present utility model to cool down, the compressed gas of the 5-8 kilogram air inlet from the two ends, left and right of connecting plate component body simultaneously enters, the air outlet connecting component body is arrived through air-cooled passage, enter back in the blind hole of the tensioning bolt that the nut seat in the installing hole of mounting assembly body connects, from the side opening of blind hole out after, subsequently in blind slot and the space that compresses between panel, flexible member therein is cooled down.So, when slag damming mechanism works, all parts in tension assembly can reliably be cooled down by cold air air-flow, and the gas outlet finally by the upper and lower both ends of the surface of blind slot is discharged, and whole cooling work process terminates.
The advantage of high-efficiency air cooling structure of the present utility model is: in (1) this utility model cooling source of the gas from the side opening of several tensioning bolts being positioned at blind slot hole out after, equably all parts in tension assembly are cooled down, ensure that the cooling source of the gas flow when cooling and pressure are the most constant, cooling effect is fabulous, is better than the cooling effect of existing converter slag-resisting mechanism cooling structure out and away；Meanwhile, the service life of converter slag-resisting mechanism can be extended, thus cost-effective；(2) use this utility model not only can change slag damming mechanism online but also can during off-line changes slag damming mechanism easily refractory brick, both ensure that the personal safety of workmen, and shortened again the engineering time, drastically increase work efficiency；(3) joint of this utility model cooling source of the gas is away from high temperature Duo Zha district, and airduct and joint are not easy to damage, and air cooling effect is good, and air cooling system instream factor is the highest.
