As shown in Fig. 4 (c), the bocca 7 of a pair of burner 6 to the configuration of cover 8 both can along internal perisporium face 3a circumferentially and be arranged above and below (pattern i), also can be along the length direction of internal perisporium face 3a and (pattern ii) arranged in the left and right, perhaps can also reach up and down the mode oblique arrangement (pattern iii) of left and right with dislocation.
The burner flame that each bocca 7 of a pair of burner 6 generates is relevant to the length direction of internal perisporium face 3a, as shown in Fig. 4 (d), the burner flame direction was not intersected (in pattern A: Fig. 4 (a), solid line A represents burner flame), also can intersect (in pattern B: Fig. 4 (a), dotted line B represents burner flame).In the B pattern that intersects, the burner 6 that is positioned at torpedo car 1 front side becomes the rear burner, and the burner 6 that is positioned at torpedo car 1 rear side becomes the place ahead burner.
In addition, the burner flame that each bocca 7 of a pair of burner 6 generates is circumferential relevant to internal perisporium face 3a's, as shown in Fig. 4 (e), the burner flame direction was not intersected (in pattern X: Fig. 4 (b), solid line X represents burner flame), also can intersect (in pattern Y: Fig. 4 (b), dotted line Y represents burner flame).And, can also make the burner flame direction towards equidirectional (pattern Z).
By the incompatible setting burner flame of above-mentioned pattern groups.For example, to become " configuration of bocca 7 being formed pattern i; with respect to the burner flame of the length direction pattern generation A of internal perisporium face 3a; with respect to the burner flame of the circumferential pattern generation X of internal perisporium face 3a " or the modes such as " configuration of bocca 7 being formed pattern iii; with respect to the burner flame of the length direction pattern generation B of internal perisporium face 3a, with respect to the burner flame of the circumferential pattern generation Y of internal perisporium face 3a " that becomes is carried out various settings.
By the bocca 7 of each burner 6 is set as mentioned above, and make each burner 6 burner flame separately along internal perisporium face 3a, and mutually oppositely generate from middle body C forward end part F side and the rear end part R side of torpedo car 1.
Fig. 5 (a) is the local vertical view cutaway drawing that the pig iron injects the periphery of outlet 4, Fig. 5 (b) is this local side view cutaway drawing, inject the periphery of outlet 4 at the pig iron, be accompanied by the pig iron to the injection of internal space S or the discharge of space S internally, and exist the V such as the pig iron to adhere to, and then the situation of cooling adhesion.In the present embodiment, in order to make the V such as the pig iron fusing of adhesion by the burner fire inflammation, and at burner flame (for example, A, X) in the scope of not blocked by inboard peristoma 4b, the mode of the bocca 7 of burner 6 being injected the central part of outlet 4 to be positioned at the pig iron is arranged at cover 8, and it is injected near the inboard peristoma 4b of outlet 4 towards the pig iron.
Next, the effect of the heating apparatus for torpedo car of present embodiment described.During the torpedo car 1 of accepting the pig iron stopped at stop position, the mobile device 10 that is equipped with a pair of burner 6 grades was kept out of the way retreating position.
Arrive, stop and injecting operation before the pig iron as torpedo car 1, when carrying out pre-hot work, chassis 12 moves horizontally on moving track 11, stops near torpedo car 1.After chassis 12 stopped, case body 2 circled round, and the pig iron injection outlet 4 for horizontally set seals the cover 8 that a pair of burner 6 is installed airtightly from torpedo car 1 side horizontal pressing.
Sealed pig iron injection outlet 4 by cover 8 after, utilize igniter (not shown) that a pair of burner 6 is lighted a fire.In the situation that common burner, the running of sustained combustion afterwards, with the internal atmosphere heating, and to torpedo car 1 inside carrying out preheating.In the situation that heat-accumulation combustor, to the place ahead with and the burner used of rear with controls of turning round of the mode of the burning running that substitutes them and exhaust accumulation of heat running, and lasting warm-up operation.
The bocca 7 of the burner 6 of the side in a pair of burner 6 circumferentially reaches length direction the place ahead inclination with respect to internal perisporium face 3a to it, the bocca 7 of the opposing party's burner 6 circumferentially reaches length direction rear inclination with respect to internal perisporium face 3a to it, to advance from bocca 7 is straight respectively, from the middle body C of torpedo car 1 along internal perisporium face 3a circumferentially, then alongst the place ahead and rear generate burner flame from each bocca 7 towards the directive property of the fore-end F of internal perisporium face 3a and rear end part R.
So, become in the internal space S that is flowing in long tubular of the burning gases that generate along the burner flame of internal perisporium face 3a towards torpedo car 1 circumferentially and the air-flow that flows in the shape of a spiral of length direction the place ahead and rear, arrive this long tubular internal space S each corner and internal atmosphere integral body is heated into high temperature.And, even in the situation that the pig iron injects the periphery adhesion of outlet 4, the V such as the pig iron are arranged, the outside peristoma 4a that the V such as this pig iron also can be injected from the pig iron outlet 4 melts towards the burner flame of internal space S ejection, therefore can generate reliably the burner flame with directive property.
After the preheating end of job, after burner 6 extinguishes, inject outlet 4 from the pig iron and take off cover 8, mobile device 10 is retreated and make a pair of burner 6 grades be moved horizontally to retreating position, then, upwards make case body 2 rotations in order to make the pig iron inject outlet 4, inject outlet 4 from the pig iron that makes progress and inject the pig iron.
in the heating apparatus for torpedo car of present embodiment described above, inject the peristoma 4a position, the outside of outlet 4 at the pig iron, towards internal space S, a pair of burner 6 that the place ahead is used and the rear is used is set, so that described a pair of burner 6 burner flame separately is along internal perisporium face 3a and from the middle body C of torpedo car 1 mode towards fore-end F side and rear end part R side, making described a pair of burner 6 bocca 7 separately circumferentially reach length direction with respect to internal perisporium face 3a to it tilts, therefore pass through the setting of the bocca 7 of this burner 6, a pair of burner 6 need not be inserted and can suitably heat internal atmosphere to the internal space S of torpedo car 1.And this pig iron injection outlet 4 narrows down even pig iron injection outlet 4 peripheries are adhered the V such as the pig iron is arranged, and also can suitably carry out preheating to internal atmosphere.
Fig. 6 represents the air-flow by the flame of burner flame generation.Fig. 6 (a) is illustrated in the situation of the heat-accumulation combustor 6 that carries out the exhaust of burnt gas E in the exhaust running and burn, and Fig. 6 (b) expression is the situation of general burner 6 usually.In the situation that common general burner 6 injects at cover 8 and the pig iron gap of setting the exhaust of guaranteeing burnt gas E between outlet 4.
the burner flame that setting by above-mentioned bocca 7 generates (for example, A, X) generate along internal perisporium face 3a towards the directive property of fore-end F and rear end part R with the middle body C from internal perisporium face 3a, then, as shown in Figure 6, by described burner flame A, in the internal space S that is flowing in long tubular of the air-flow G of the flame that X generates, become the high fluidity and the strong air-flow of stirring action that flow in the shape of a spiral towards circumferential and length direction the place ahead or the rear of torpedo car 1, therefore can successfully arrive this long tubular internal space S each corner and internal atmosphere integral body is heated into high temperature equably.
In addition, also can effectively heat by the burner flame along internal perisporium face 3a internal perisporium 3 self, can improve pre-heat effect.Therefore so, can carry out expeditiously preheating, can make the burner capacity miniaturization, so can utilize microburner to carry out preheating, even thereby the pig iron to inject outlet 4 little, also can suitably carry out preheating.
In the situation that common burner 6, as shown in Fig. 6 (b), can forwards heat with the rear simultaneously, but as the exhaust outlet of the air-flow G (burnt gas E) of flame, ground same need to separate the gap between cover 8 and pig iron injection outlet 4.With respect to this, when adopting heat-accumulation combustor 6, as shown in Fig. 6 (a), carry out the exhaust of burnt gas E by one-sided burner, therefore can seal and airtight gap, not only can not leak heat, and the heat that can reclaim exhaust carries out accumulation of heat and recycles, compared with the past, can improve the effect of saving energy.
adhere in order to make by burner flame the V such as the pig iron fusing that the pig iron injects outlet 4 peripheries, and the bocca 7 of burner 6 is arranged on the central part that the pig iron injects outlet 4, and make it inject near the inboard peristoma 4b of outlet 4 towards this pig iron, therefore can make reliably by the burner flame from pig iron injection outlet 4 to the internal space S ejection and adhere to the V such as the pig iron fusing that the pig iron injects outlet 4 peripheries, burner flame can be sent into and suitably and equably internal atmosphere carried out preheating to internal space S reliably, and when the injection operation of the post-job pig iron of preheating, can remove and adhere to the V such as the pig iron that the pig iron injects outlet 4 peripheries, and the torpedo car 1 of successfully pig iron being packed into.
in the present embodiment, a pair of burner 6 carries on the mobile device 10 that moves horizontally freely, move horizontally by mobile device 10, and the pig iron that is connected to horizontally set injects the peristoma 4a position, the outside of outlet 4, therefore as shown in Fig. 7 (a), by small-sized and simple structure and with simple move horizontally this easily operation just can carry out burner 6 to the installation of torpedo car 1, from construct equipment that frame 16 grades need the complicated of certain altitude and cost cost and different by the situation of descending operation erection weight thing as shown in Fig. 7 (b), can improve workability.
In addition, by using heat-accumulation combustor, can save energy and implement pre-hot work with low NOx.
