Abstract
The utility model relates to an oxygen lance nozzle in no need of water cooling. The oxygen lance nozzle comprises a circular flange and a cast steel pipe, wherein the circular flange is arranged at one end of the cast steel pipe and a mounting plate is arranged at the other end of the cast steel pipe, the inclined angle between the mounting plate and the cast steel pipe is alpha; the circular flange, the cast steel pipe and the mounting plate are made of rare earth heat-resistant and wear-resistant steel; and the inclined angle alpha between the mounting plate and the cast steel pipe is 35 degrees. The oxygen lance nozzle disclosed by the utility model has the advantages that the structure is reasonable, the disassembly is convenient, the service life is above 16 months, the cost is saved by **-**yuan, the production efficiency is increased, the labor intensity of workers is reduced, safety and reliability are achieved and the energy consumption is reduced due to no need of water cooling. The oxygen lance nozzle disclosed by the utility model is suitable for being used in the converter of a steelmaking plant.
Description
Technical field
The utility model relates to the field such as power station, metallurgy, and specially referring to the one using in converter need not water-cooled oxygen muzzle.
Background technology
Oxygen rifle is entered in stove by converter mouth by the nitrogen seal device on gasification cooling flue, oxygen muzzle, in the time of blowing, converter body is in vertical position, oxygen rifle is from dropping to when position blowing and start oxygen blast wait blowing position, need to the sampling of falling stove and when the observation working of a furnace to terminal when smelting, first carry rifle and stop oxygen, oxygen rifle will enter position to be blown through oxygen muzzle, nitrogen seal device; Nitrogen system, is banked up a fire to the inside of oxygen muzzle with nitrogen for nitrogen to nitrogen seal device.As shown in Figure 1, Figure 2, Figure 3 shows, oxygen muzzle often adopts Q235 steel pipe manufacturing to prior art, and the steel pipe outer ring of oxygen muzzle upper end arranges the cooling tube going with each other all the time; Oxygen muzzle bottom arranges tens of cooling tubes, and water coolant low in and high out forms cooling water channel.Oxygen muzzle is arranged on 22 meters of high-altitudes conventionally, under the high temperature more than 1200 degree, works, and due to adhering to of the splashings such as thermal-flame in being smelted and slag liquid, steel pipe easily damages generation leakage accident, and only have 2～3 months general work-ing life; Oxygen muzzle complex structure, dismounting difficulty, servicing time are long, affect production efficiency, and workman's labour intensity is larger; Use water quench, energy consumption is high, and safety in production is impacted.
Summary of the invention
The purpose of this utility model is to overcome the problem occurring in above-mentioned background.
The utility model is achieved in that one need not water-cooled oxygen muzzle, comprise round flange, casting steel tube, it is characterized in that: described casting steel tube one end is provided with round flange, and the other end is provided with mounting plate, the angle between casting steel tube and mounting plate is α.
The material of round flange described in the utility model, casting steel tube, mounting plate all adopts heat-resistant wear-resisting rare earth steel.
Angle α between casting steel tube described in the utility model and mounting plate is 35 degree.
The utility model is rational in infrastructure, and long service life is easy to maintenance, has improved production efficiency, has alleviated workman's labour intensity, without water cooling safety and reliability, reduction energy consumption, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
One need not water-cooled oxygen muzzle, comprises round flange 3, casting steel tube 4, it is characterized in that: described casting steel tube 4 one end are provided with round flange 3, and the other end is provided with mounting plate 5, and the angle between casting steel tube 4 and mounting plate 5 is α; The material of round flange 3, casting steel tube 4, mounting plate 5 all adopts heat-resistant wear-resisting rare earth steel; Angle α between casting steel tube 4 and mounting plate 5 is 35 degree.
When concrete enforcement, as shown in Figure 1, except analysing and observe direction, the direction of arrow is cooling water intakeoutfall direction.As shown in Figure 4, round flange 3, casting steel tube 4, mounting plate 5 all adopt the casting of heat-resistant wear-resisting rare earth steel.The external diameter of round flange 3 is 800mm, and thickness is 20mm; The external diameter of casting steel tube 4 is 550mm, wall thickness 25mm, the angle α between processing inclined-plane and horizontal direction; The physical dimension of mounting plate 5 is 2468mm × 1150mm × 20mm, all processes according to design paper.When welded and installed, round flange is of a size of L to the Center Length of mounting plate, L=1900mm, and the angle between casting steel tube 4 and mounting plate 5 is α, angle α is 35 degree.In actual use, the utility model was saved 15～200,000 yuan than prior art oxygen muzzle structure in 1 year work-ing life more than 16 months.
