Description
Technical field
The utility model relates to a kind of hot metal pretreatment spray gun locating device.
Background technology
The molten iron expulsion problem of desulfuration injection process is the difficult problem in hot metal pretreatment technology always.The reason of splash is many-sided, and intricate.Relatively more outstanding reason is: spray gun spills iron to the splash that the stirring of molten iron produces in desulfuration injection process.
One adopts hundred tons of iron ladle desulfurization, and iron ladle tank mouth diameter only has 3.2m, and desulphurization spray gun gun rack adopts steel welding structure.In hot metal pretreatment winding-up process, the air-flow that the gasification of delivering gas, MAGNESIUM METAL and water vapour produce in molten iron and MAGNESIUM METAL reaction make the generation of molten iron surface seethe, spray gun is all around significantly swung in iron ladle, very large whipping force can be produced to molten iron in tank.Particularly when desulphurization spray gun discharge hole is near molten iron tank skin, desulphurised hot metal splashing distance will be greater than iron ladle radius, produces splash and seriously spills iron.
Iron harm is spilt in desulfurization splash:
Molten iron loss is serious: the every tank of molten iron loss amount caused due to splash is about between 0.1-1 ton, on average about 0.55 ton.Structure deteriorate is serious: because splash is serious, often occur soldering iron road phenomenon, causes railway to be out of shape, ruptures.
Post labor strength is large: because splash is serious, and per tour at least will be taken out between cleaning winding-up in 1.5 hours and spill iron.
Desulfurization station operating rate reduces: process splash is spilt iron and reduced desulfurization station operating rate, and the actual job rate at present desulfurization station only has 70%-80%, and often causes the iron phenomenons such as converter smelting to occur.
Potential safety hazard is large: the cooled plate caused due to desulfurization splash, splash guard are hung iron and easily caused object strike accident; Soldering iron road finds not in time, also may cause great industrial accident.
According to statistics: in Hot Metal Pretreatment, desulphurization spray gun solves desulfurization splash all around and spills iron and account for and always spill about 80% of iron, and ratio is larger sometimes.Therefore the key issue of iron is spilt in solution desulfurization splash is stable spray gun.Rifle swings less in winding-up process, and it is fewer that iron is spilt in splash; Otherwise it is more.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hot metal pretreatment spray gun locating device, prevents spray gun from significantly swinging in iron ladle all around, and then solves the problem that iron is spilt in desulfurization splash.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of hot metal pretreatment spray gun locating device, comprise gunjet rack, lift cart, spray gun is fixed with bottom lift cart, also comprise fixing slide block, guide runner, bracing frame, two fixing slide blocks are fixed on the both sides of gunjet rack respectively by bracing frame, lift cart both sides are fixed with guide runner, and fixing slide block is provided with chute, and guide runner and chute match.
Described fixing slide block is connected by slide with guide runner.
Described fixing slide block is wedge shape, and chute is arranged on the lozenges of fixing slide block, guide runner and fixing slide block grafting.
Described bracing frame is fixedly connected with by the upper, middle and lower segment of bolt with fixing slide block.
Compared with prior art, the beneficial effects of the utility model are:
In desulfuration injection process, what all around the rocking of desulphurization spray gun was caused spills iron phenomenon basically eliminate, and the equipment such as spray gun gun rack, lift cart is effectively protected simultaneously, and the desulphurization spray gun life-span significantly improves.Utilize the grafting of fixing slide block and guide runner to fix, eliminate the generation of the dancing all around of spray gun, the wedge structure of fixing slide block adds grafting area, meanwhile, coordinates lift cart and spray gun deadweight to also prevent moving up and down of spray gun; Significantly reduce the molten iron loss that splash causes; Stop because splash seriously causes distortion, fracture, soldering iron road phenomenon; Reduce post labor strength; Improve desulfurization station operating rate.

Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 4, a kind of hot metal pretreatment spray gun locating device, comprise gunjet rack 1, lift cart 3, spray gun 2 is fixed with bottom lift cart 3, also comprise fixing slide block 5, guide runner 6, bracing frame 4, two fixing slide blocks 5 are fixed on gunjet rack 1 both sides respectively by bracing frame 4, lift cart 3 both sides are fixed with guide runner 6, fixing slide block 5 is provided with chute 7, and guide runner 6 and chute 7 match.
Wherein, fixing slide block 5 is slidably connected by chute 7 with guide runner 6.Fixing slide block 5 is wedge shape, and chute 7 is arranged on the lozenges of fixing slide block 5, guide runner 6 and the grafting of fixing slide block 5.Bracing frame 4 is fixedly connected with by the upper, middle and lower segment of bolt with fixing slide block 5.For convenience of making, the cross section of chute 7 is rectangle, also can be trilateral.The length of chute 7 also can need to make according to scene.
Hot metal pretreatment spray gun localization method, fixing slide block 5 is fixed on spray gun 2 and blows a position, and lift cart 3 drives spray gun 2 to drop to spray gun 2 when to blow, and guide runner 6 is plugged in the chute 7 of fixing slide block 5, and what realize spray gun 2 is fixing.
Embodiment:
For 100t iron ladle desulphurization spray gun 2 localization method:
The gun rack position installation fixing support rack 4 of position (spray gun 2 runs smallest limit) correspondence of jetting at desulphurization spray gun 2, in bracing frame 4 both sides, each vertical installation shape, positive wedge shape irony that size is identical fix slide block 5, and process a chute 7 as slideway on fixing slide block 5 scarp.
The each vertical installation irony of falling wedge shape guide runner 6 in lift cart 3 both sides.The inclined-plane of guide runner 6 is identical with chute 7 width of fixing slide block 5, and two inclination angle of inclined plane absolute values are identical.Can ensure that in the inclined-plane of guide runner 6 and the chute 7 of fixing slide block 5, inclined-plane is at position close registration of jetting like this, desulphurization spray gun 2 not produced in winding-up process and all around rocks; The self gravitation of desulphurization spray gun 2 and lift cart 3 ensure that desulphurization spray gun 2 does not produce up-down vibration in winding-up process; Thus ensure that desulphurization spray gun 2 is positioned at iron ladle center all the time in winding-up process.
In addition, spray gun 2 gun rack, in long-term operational process, can produce faint distortion, affects the locating effect of locating device.For this reason when installing bracing frame 4, be separately fixed at the upper, middle and lower segment position of fixing slide block 5, one is prevent gunjet rack 1 moderate finite deformation, and two is to the adjustment of distortion gun rack, also prevent the skew of fixing slide block 5.
The utility model is in desulfuration injection process, and what all around the rocking of desulphurization spray gun 2 was caused spills iron phenomenon basically eliminate, and the equipment such as spray gun 2 gun rack, lift cart 3 is effectively protected simultaneously, and desulphurization spray gun 2 life-span significantly improves.Utilize fixing slide block 5 to fix with the grafting of guide runner 6, eliminate the generation of the dancing all around of spray gun 2, the wedge structure of fixing slide block 5 adds grafting area, meanwhile, coordinates lift cart 3 and spray gun 2 deadweight to also prevent moving up and down of spray gun 2; Significantly reduce the molten iron loss that splash causes; Stop because splash seriously causes distortion, fracture, soldering iron road phenomenon; Reduce post labor strength; Improve desulfurization station operating rate.
