Background technology
Cluster fluidic (Coherent Jet is called for short COJET) oxygen rifle is a kind of novel oxygen rifle of developing in recent years.This kind oxygen rifle is the applied aeromechanics principle, has added on traditional oxygen rifle and has followed streaming system, and the oxygen jet rate of decay is slowed down greatly, forms a kind of technology of the oxygen jet that is similar to laser beam.This jet concentration of energy has extremely strong penetrativity, to promoting slag-metal reaction, even molten steel composition and temperature, minimizing splash, raising oxygen utilization rate, raising recovery rate of iron etc. fairly obvious effect is arranged all.Because the enhancing of penetrativity, oxygen lance position can suitably improve during blowing, therefore can reduce the consumption of oxygen rifle.Yet tradition oxygen rifle commonly used only has simple spray oxygen function, and the very big decay of its oxygen jet existence, has had a strong impact on the realization of the various functions of oxygen rifle, as one of terms of settlement, adopts the cluster fluidic rifle of import just can address this problem preferably.Yet, even the cluster fluidic rifle of import has stronger advantage on product wearing quality and technological quality, but cost an arm and a leg on the one hand, corresponding to the steel melting furnace of each different sizes, the effect that the cluster fluidic rifle is played in practical application is really still limited on the other hand.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of cluster fluidic rifle, to solve in traditional process for making the serious restriction that the cluster fluidic rifle of steel melting furnace promotes steel output, and huge product maintenance cost input problem.
The purpose of this utility model will be achieved by the following technical programs:
A kind of cluster fluidic rifle, be installed on the steel-smelting electric furnace furnace wall, it is characterized in that: the body of a gun of described cluster fluidic rifle is three sleeve type structures, it comprise the central position main oxygen jet pipe, be sheathed on outer field exhaust gas nozzle of main oxygen jet pipe and secondary oxygen jet pipe, weldering connects combination between each function jet pipe, and described main oxygen jet pipe is provided with the main oxygen hole of Lavalle cellular type in spray nozzle part.
Further, for improving the work-ing life of main oxygen jet pipe, promptly thermal conductivity reduces the molten steel adhesion, the seamless tube of this main oxygen jet pipe for being made by red copper; And this exhaust gas nozzle and secondary oxygen jet pipe are thick-walled seamless steel pipes.
Further, aforesaid cluster fluidic rifle, its body of a gun skin also is provided with the water-cooled body, and is provided with water-in and water outlet at the water-cooled body away from an end of described main oxygen hole.
The application implementation of the utility model cluster fluidic rifle, its outstanding effect is:
This cluster fluidic rifle that selection and conventional complete processing by material makes, the speed of the oxygen rifle jet that can significantly slow down decay, thereby the cleaning efficiency and the cost of steel-smelting electric furnace space for collecting ashes in a stove have been saved, improved the output of steel in the unit time, a kind of new approaches that reduce the maintenance cost of space for collecting ashes in a stove and cluster fluidic rifle are provided simultaneously.This cluster fluidic rifle processing is easy, is easy to popularization, volume production.
Following constipation closes the embodiment accompanying drawing, the embodiment of the utility model cluster fluidic rifle is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural profile synoptic diagram of the utility model cluster fluidic rifle.
Embodiment
The cluster fluidic rifle has added on traditional oxygen rifle follows streaming system, promptly follows the main oxygen securing system that is provided with exhaust gas nozzle, secondary oxygen jet pipe formation in main oxygen injection system periphery.The oxygen jet rate of decay is slowed down greatly, form a kind of technology of the oxygen jet that is similar to laser beam.
This technology effusive structural profile synoptic diagram as shown in Figure 1 is as seen: the body of a gun of this cluster fluidic rifle is three sleeve type structures, it comprise the central position main oxygen jet pipe 1, be sheathed on outer field exhaust gas nozzle 2 of main oxygen jet pipe and secondary oxygen jet pipe 3, and this main oxygen jet pipe 1 also is provided with the main oxygen hole of Lavalle cellular type in spray nozzle part, for improving the work-ing life of main oxygen jet pipe 1, be that thermal conductivity reduces the molten steel adhesion, the seamless tube of this main oxygen jet pipe 1 for making by red copper; This exhaust gas nozzle 2 and secondary oxygen jet pipe 3 process each function jet pipe and be integrated and also can be thick-walled seamless steel pipes by soldered point 4 soldering group.And be provided with fuel gas inlet 21 and be provided with gas outlet 31 equally at the seal welding end side of secondary oxygen jet pipe 3 and combustion gas airduct 2 outer walls at the seal welding end side of exhaust gas nozzle 2 and main oxygen jet pipe 1 outer wall
In addition,, also be provided with the water-cooled body, and be provided with water-in and water outlet away from an end of described main oxygen hole, just form one four body belled structure at the water-cooled body at its body of a gun skin as extendability design of the present utility model.
To the molten bath oxygen supply, secondary oxygen jet pipe is with 8m with the supersonic speed of Ma=2 for the main oxygen jet pipe of this cluster fluidic rifle
3The speed of/min is protected supersonic jet, guarantees the supersonic jet compactness, links up and enters the molten bath effectively, and secondary combustion oxygen is provided simultaneously.
This jet concentration of energy has extremely strong penetrativity, to promoting slag-metal reaction, even molten steel composition and temperature, minimizing splash, raising oxygen utilization rate, raising recovery rate of iron etc. fairly obvious effect is arranged all.Because the enhancing of penetrativity, oxygen lance position can suitably improve during blowing, therefore can reduce the consumption of oxygen rifle.This technology has obtained a ton steel nearly 50 yuan positive effect that reduces cost.The primary income that the technology fluidic oxygen gun is applied to steel melting furnace is embodied in: (1) therefore can reduce the brickwork cost because the enhancing of stirring capacity can be cancelled bottom blowing system.(2) because the raising of decarbonization rate has improved production operational availability.(3) because the reduction of iron level in the minimizing of splash and the slag, recovery rate of iron improves, and output of steel increases, and has reduced the maintenance cost of space for collecting ashes in a stove simultaneously.(4), reduce deoxidation and consume with aluminium owing to the reduction of terminal point [O] in the steel.(5) owing to the raising of rifle position and the minimizing of splash, life-span of oxygen lance improves.
