Technical field
The utility model combination forging and pressing oxygen lance blow head relates to the smelting equipment parts of steel, specifically the combination forging and pressing oxygen lance blow head used of Oxygen Furnace Steel.
Background technology
When the oxygen rifle is worked in converter or other steel melting furnace, carrying out complicated, fierce metallurgical reaction in the stove, oxygen lance blow head is subjected to complicated thermal loads such as radiation, convection current and the conduction of high-temperature furnace gas, also has the continuous erosion of high temperature furnace slag and splash in addition, Working environment is very abominable, impact molten iron high temperature reaction zone territory at oxygen jet, temperature can be up to 2500 ℃～and 3000 ℃, the suffered thermal load of oxygen lance blow head end face can be up to 0.23～0.41 * 10
6/ Kcarm
-2Hr
-1, localized heat load can be up to 3.2 * 10 moment sometimes
6/ Kcarm
-2Hr
-1Though high-intensity Forced water cooling cooling has been adopted in oxygen lance blow head inside, but organizing of the fine copper of existing routine casting production casting oxygen lance blow head is not fine and close, hardness is very low, thermal conductivity is relatively poor, in high temperature furnace slag and molten iron splash, wash away, erosive moment, red copper on the oxygen lance blow head surface is very easy to form the point-like corrode, and produce alloying reaction with slag and molten iron, generate copper-iron alloy, stick to the end face of oxygen lance blow head firmly, because the thermal conductivity of copper-iron alloy is lower more than 100 times than fine copper, so greatly reduced the heat conductivility of oxygen lance blow head end face, the work-ing life of having reduced oxygen lance blow head.
The utility model content
The utility model combination forging and pressing oxygen lance blow head is at the defective of prior art, in order to improve oxygen lance blow head work-ing life and blowing effect, reduce resource consumption, a kind of structure that makes up the forging and pressing oxygen lance blow head is disclosed, be made up of nozzle body, water eliminator, outer welded tube, middle welded tube, interior welded tube, it is characterized in that the nozzle body pattern that is structure as a whole, nozzle body comprises oxygen shunting end and oxygen outlet end, oxygen blast hole and shower nozzle medullary ray angle are α, and the scope of α is: 7 °～20 °.Combination Welding was made after nozzle body adopted the copper coin forging forming.Water eliminator can adopt the Sheet Metal Forming Technology once shaped, adopts spot welding mode of connection and nozzle body to be assembled into one then.
The key distinction of the utility model combination forging and pressing oxygen lance blow head and prior art oxygen lance blow head be nozzle body partly adopt the copper coin forging forming after Combination Welding make, density by 8.5 bring up to 8.9, hardness brings up to HL350～380 by hardness of cast form HL50, strengthened the capacity of heat transmission of shower nozzle, make slag be difficult to stick to the shower nozzle end face and be easy to come off, slowed down the erosion of high temperature furnace slag and molten iron to the shower nozzle end face, improved the work-ing life of shower nozzle, can reach 2 times of routine casting shower nozzle.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model combination forging and pressing oxygen lance blow head structure.
In the accompanying drawing: 1, interior welded tube; 2, middle welded tube; 3, outer welded tube; 4, water eliminator; 5, oxygen outlet end; 6, oxygen blast hole; 7, weld seam; 8, oxygen shunting end; 9, post metapore.
α is oxygen blast hole and shower nozzle medullary ray angle;
β is that oxygen shunting end feeding oxygen hole shrinks cone angle.
Embodiment
An embodiment of the utility model combination forging and pressing oxygen lance blow head as shown in Figure 1, form by oxygen shunting end 8, weld seam 7, oxygen blast hole 6, oxygen outlet end 5, water eliminator 4, outer welded tube 3, middle welded tube 2, interior welded tube 1, the nozzle body pattern that is structure as a whole, nozzle body comprises oxygen shunting end 8 and oxygen outlet end 5, oxygen blast hole 6 is α with shower nozzle medullary ray angle, and the scope of α is: 7 °～20 °.
As preferred embodiment, in conjunction with the accompanying drawings 1, oxygen shunting end 8 has oxygen shunting end feeding oxygen hole to shrink cone angle beta, and feeding oxygen hole shrinks cone angle beta the effect of shrinking and quickening air-flow, and it is corresponding with 6 positions, oxygen blast hole, the quantity of nozzle body that feeding oxygen hole shrinks cone angle beta; Oxygen shunting end 8 adopts welding fabrication to form nozzle body with oxygen outlet end 5, and water eliminator 4 links into an integrated entity by spot welding with nozzle body, has reduced welding stress, and outer welded tube 3, middle welded tube 2, interior welded tube 1 are integrally welded with nozzle body respectively; Oxygen blast hole 6 numbers of nozzle body can be by the uniform or non-homogeneous layout in peripheral 3 holes～8 holes, and sprinkler design is practical more flexibly; Water eliminator 4 leaves post metapore 9, and post metapore 9 can reduce the cooling water pressure loss, increases the cooling intensity of oxygen lance blow head, the work-ing life of improving oxygen lance blow head; Shower nozzle water eliminator 4 and middle welded tube 2 adopt and be threaded or weld, and be easy to connect, reduces the welding stress of oxygen lance blow head, reduces stress deformation in the oxygen lance blow head use, improves oxygen and rob shower nozzle work-ing life.
The assembling welding was made after the main part of shower nozzle adopted the copper coin forging forming, nozzle body particularly density, the hardness at position around end face and 6 outlets of oxygen blast hole have been improved effectively, physicals, the mechanical property of oxygen lance blow head have been changed, the capacity of heat transmission, the resistance to corrosion of shower nozzle have been strengthened, make slag be difficult to stick to the oxygen lance blow head end face and be easy to come off, slowed down the erosion of high temperature furnace slag and molten iron, improved the work-ing life of oxygen lance blow head the oxygen lance blow head end face.
