Technical field
The utility model relates to a kind of electric arc furnace accessory facility, is specifically related to a kind of electric arc furnace top oxygen blowing gun device.
Background technology
In the electric-arc furnace steelmaking production process, energy consumption per ton steel is higher to be one of difficult problem of at present existence of steel-making enterprise.In order to reduce energy consumption per ton steel, generally all be to adopt the input that increases oxygen, improve electric arc furnace combustion efficient, thus energy-saving and cost-reducing.At present, the mode of oxygen therapy all adopts water-cooled furnace door oxygen therapy, but oxygen utilization rate is lower, and Oxygen Flow is impacted molten steel can cause splash, the time have the accident of scalding the staff to occur, safety performance is relatively poor.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide that a kind of oxygen utilization rate is high, the oxygen splash is few, the electric arc furnace top oxygen blowing gun device that safety performance is high.
In order to achieve the above object, the technical solution of the utility model: a kind of electric arc furnace top oxygen blowing gun device, comprise oxygen channel, be provided with cooling water pipeline in this oxygen channel outer race, have water-in and water outlet on this cooling water pipeline; The end of described oxygen channel has a plurality of spray oxygen mouths, wherein, described a plurality of spray oxygen mouth comprises the main jet oxygen mouth of central position and sprays the oxygen mouth around the circumferential setting of this main jet oxygen mouth and by First Series spray oxygen mouth, second series that the central position outwards sets gradually respectively; Be provided with an automatic slag scraping mechanism in described cooling water pipeline periphery.
Further, the aperture of described second series spray oxygen mouth is greater than the aperture of described First Series spray oxygen mouth; The aperture of described main jet oxygen mouth is greater than the aperture of described second series spray oxygen mouth.Particularly, the aperture of described First Series spray oxygen mouth is 13mm; The aperture of described second series spray oxygen mouth is 17mm.
Described automatic slag scraping mechanism comprises that support portion and slip cap be located at the operate portions of described cooling water pipeline periphery, and this operate portions and described support portion are one-body molded.End near described spray oxygen mouth on the described operate portions is tapered.
The beneficial effects of the utility model: carry out water-cooled oxygen therapy by recirculated cooling water in the oxygen channel periphery; The spray oxygen mouth of oxygen channel adopts multi-port to come molten steel is carried out oxygen blast simultaneously, and than traditional top blow oxygen lance, molten steel temperature is even in the electric arc furnace, and shorten tap to tap time, and the oxygen splash is less.Be provided with self-skimming mechanism in described cooling water pipeline outer race, prevent that a small amount of splash molten steel is attached to outside the described cooling water pipeline, thereby and then the mating surface that damages this electric arc furnace top oxygen blowing gun device and miscellaneous equipment cause equipment to keep in repair, increase maintenance cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the spout distribution schematic diagram of spray gun among Fig. 1.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of electric arc furnace top oxygen blowing gun device as depicted in figs. 1 and 2 comprises oxygen channel 10, is provided with cooling water pipeline 20 in described oxygen channel 10 outer race, has water-in 21 and water outlet 22 on this cooling water pipeline 20; The end of described oxygen channel 10 has a plurality of spray oxygen mouths 40, wherein, described a plurality of spray oxygen mouth 40 comprises the main jet oxygen mouth 400 of central position and sprays oxygen mouth 402 around these main jet oxygen mouth 400 circumferential settings and by First Series spray oxygen mouth 401, second series that the central position outwards sets gradually respectively; Be provided with an automatic slag scraping mechanism in described cooling water pipeline 20 peripheries.
Cooling water pipeline 20 in the utility model is welded on described oxygen channel 10 outer circular arc sheet materials by several and forms negotiable cooling water circulationly, and the continuous water cycle by water-in 21 and water outlet 22 is to reach water-cooled oxygen therapy.
Described spray oxygen mouth 40 is combined by three kinds of forms.One is located at the main jet oxygen mouth 400 of position, oxygen channel 10 axis, and the flow of oxygen to interior by the oxygen direction of these main jet oxygen mouth 400 ejections and described oxygen channel 10 is consistent; They are two years old, contiguous this main jet oxygen mouth 400 and be the First Series spray oxygen mouth 401 of circumferential distribution around this main jet oxygen mouth 400, the quantity of this First Series spray oxygen mouth 401 can be decided according to practical situation, in this example, the quantity of this First Series spray oxygen mouth 401 is four, and the aperture is 13mm; They are three years old, contiguous First Series sprays oxygen mouth 401 and is the second series spray oxygen mouth 402 of circumferential distribution around described main jet oxygen mouth 400, and the quantity of this second series spray oxygen mouth 402 can be decided according to practical situation, in this example, the quantity of this second series spray oxygen mouth 402 is four, and the aperture is 17mm.Come the molten steel in the electric arc furnace is carried out oxygen blast by a plurality of spray oxygen mouth 40 different injection directions, different injection flow, so that molten steel temperature is even in the electric arc furnace, shorten tap to tap time, and the oxygen splash is less.
