Abstract
The utility model relates to a special buggy ladle for a low-frequency (LF) refining furnace, which comprises a ladle body, wherein guide rails and a hydraulic cylinder are fixed on the ladle body, an expansion link of the hydraulic cylinder is connected with a steel structure of a lifting platform, the steel structure of the lifting platform slides along the guide rails vertically, and a thermal-protective coating is arranged at the top end of the steel structure of the lifting platform. The special buggy ladle is formed by arranging the lifting platform on the buggy ladle for the original LF refining furnace, the thermal-protective coating is arranged at the top end of the lifting platform, the purpose of regulating the electrode of the LF refining furnace is realized through lifting the lifting platform, the special buggy ladle has the basic functions of stable driving, ladle seat positioning and steel chute leakage prevention of the buggy ladle for the original LF refining furnace, meanwhile, the electrode of the LF refining furnace can also be regulated online, the online electrode length regulation operation can be simply and effectively realized, the operating rate of a crown block can be effectively saved, and the production efficiency is improved; and meanwhile, workers do not need to operate on an electrode cross arm with the risks of high temperature, falling and electric shock, so the operation safety of the workers are guaranteed.
Description
Technical field:
The utility model belongs to the steelmaking equipment technical field, is specifically related to a kind of at the special-purpose Multifucntional buggy ladle of LF refining furnace.
Background technology:
Along with the continuous progress of smelting technology, rhythm of production can constantly be accelerated, and improving the operating efficiency of smelting production unit and the perfect in shape and function of faster production equipment is the needs of Future Development.The two LF ladle refining furnaces of treating that the single working position in seat in the plane is arranged of two cars occupy extremely important status with its good stabilization of equipment performance, property simple to operate at metallurgy industry.Wherein refining steel hired car is being brought into play important effect in LF refining production process, and further exploitation is more specialty, more practical, to have more functional LF refining special-purpose multifunctional new steel hired car necessary.The general whole overhead traveling cranes that need of the online adjusting of LF refining electrode are at present assisted; The danger that the worker need emit high temperature, fall, get an electric shock to the electric-pole horizontal arm wireline through on the electrode hangers; Hang by overhead traveling crane again, remove electric-pole horizontal arm afterwards and step up device, carry out the counter electrode length adjustment; The worker will carry out three repetitive operations and could the adjustment of three electrodes be finished like this.Then almost need the online adjusting of one-time electrode length every day at least if the LF stove calculates by the normal operation rate, can have a strong impact on the effective operation rate of overhead traveling crane like this, influence production efficiency, workers ' safety can't effectively be guaranteed simultaneously.
The utility model content:
In sum; In order to overcome the deficiency of prior art problem; The utility model provides novel LF refining a kind of fluid pressure type, that liftable is regulated, that have anti-material and positioning and guiding rail platform to use buggy ladle; It is liftable platform to be set in former LF refining on buggy ladle, and the platform top is provided with lagging material, and the up-down through lifting table reaches the purpose of regulating LF refining furnace electrode; It promptly possesses, and former LF refining is steady with the driving of buggy ladle, the ladle seat is located, anti-bleed-out chute basic function, can realize the electrode of online adjustment LF refining furnace simultaneously again.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of LF refining furnace special-purpose steel hired car comprises car body, and wherein: be fixed with guide rail and hydro-cylinder on the car body, the expansion link of hydro-cylinder is connected with the lifting gantry steelwork, and the lifting gantry steelwork slides up and down along guide rail, and lifting gantry steelwork top is provided with thermofin.
Further, the stroke >=500mm of described hydro-cylinder.
Further, described hydro-cylinder and guide rail are arranged on the left end or the right-hand member of car body.
The beneficial effect of the utility model is:
1, the utility model is liftable platform to be set in former LF refining on buggy ladle; The platform top is provided with lagging material; Up-down through lifting table reaches the purpose of regulating LF refining furnace electrode; It promptly possesses, and former LF refining is steady with the driving of buggy ladle, the ladle seat is located, anti-bleed-out chute basic function, can realize the electrode of online adjustment LF refining furnace simultaneously again.
2, the utility model can simple and effectively be implemented in the operation of line electrode length adjustment, can effectively practice thrift the overhead traveling crane operating rate, enhances productivity; The danger that the while worker need not emitting high temperature, fall, getting an electric shock is carried out operation to electric-pole horizontal arm, guaranteed worker's job safety.
3, simple in structure, the processing ease of the utility model, use, easy to maintenance are not only applicable to LF stove electrode length and regulate, and the movably lifting gantry that also can be used as maintenance or accident maintenance uses.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 looks synoptic diagram for the left side of the utility model Fig. 1;
Fig. 3 is the schematic top plan view of the utility model Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of LF refining furnace special-purpose steel hired car comprises car body 1, and the left end of car body 1 is fixed with guide rail 3 and hydro-cylinder 2; The expansion link of hydro-cylinder 2 is connected with lifting gantry steelwork 4; Hydro-cylinder 2 form 600mm, lifting gantry steelwork 4 slides up and down along guide rail 3, lifting gantry steelwork 4 tops are provided with thermofin 5.
During use; At first rise to LF electric-pole horizontal arm and bell high spacing; Lifting gantry steelwork 4 is adjusted to minimum spacing, then buggy ladle is left to the electrode regulating position, the lifting gantry steelwork 4 on the buggy ladle is alignd with three electrodes that are in vertical position on the LF stove; Lifting gantry steelwork 4 on the buggy ladle is risen to predefined height; The control electrode transverse arm is with on the electrode thermofin 5 that drops down onto lifting gantry steelwork 4 upper ends slowly; After discharging three electric-pole horizontal arms and stepping up device, decline lifting gantry steelwork 4 slowly, electrode descends with lifting gantry steelwork 4; After electrode is adjusted to appropriate length, step up device with electric-pole horizontal arm and step up three electrodes one by one, the lifting gantry steelwork 4 that slowly descends is to minimum spacing; Accomplish the adjusting of electrode length.
Be noted that; The above embodiment is to the explanation of the utility model technical scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art; As long as do not exceed the thinking and the scope of the utility model technical scheme, all should be included within the desired interest field of the utility model.
