Abstract
The utility model discloses a converter steel-smelting device for the metallurgy industry, belongs to a matched spray head for steel-smelting oxygen guns, and relates to a spray head for die forging combined type oxygen guns. The utility model is provided with a spray head oxygen blowing body, an oxygen flow division body, a water guide plate, etc. The utility model is characterized in that the lower part of the spray head oxygen blowing body is a base; the base is uniformly distributed with three to six oxygen blowing conical pipes in the circumferential direction, and is shaped into a whole through the die forging; the upper parts of the oxygen blowing conical pipes are welded with the oxygen flow division body. The interior of the oxygen blowing conical pipe is provided with an oxygen blowing hole. The included angle alpha of the axial line of the oxygen blowing hole and the axial line of the spray head oxygen blowing body is 7 DEG-18 DEG.
Description
The utility model relates to a kind of metallurgy industry converter steelmaking equipment, a kind of supporting shower nozzle--the die forging built-up type oxygen lance blow head on the steel-making oxygen rifle.
At present, what domestic converter steelmaking was adopted usually is casting center water-cooled oxygen blast shower nozzle, for monoblock casting is made, forms center water-cooled die cavity on shower nozzle.Casting technique is complicated, and the production product percent of pass is lower, and there are problems such as shower nozzle end density is little, heat conductivility is poor, the easy thermal etching distortion of shower nozzle end face in product, has influenced the work-ing life of shower nozzle.Also have several assembly type shower nozzles, the oxygen blast Taper Pipe is resolved into two sections fix, maybe will divide fluid to resolve into several parts with dividing fluid, component are many, mechanical processing technique is complicated, qualification rate is low but all exist.
The purpose of this utility model is to have overcome the deficiencies in the prior art, for converter steelmaking provide a kind of rational in infrastructure, make die forging built-up type oxygen lance blow head simple, long service life.
The content Description of the utility model die forging built-up type oxygen lance blow head:
The utility model die forging built-up type oxygen lance blow head, be by shower nozzle oxygen blast body, oxygen divides fluid, guide water board, the oxygen pipe, water-in, manage in the oxygen rifle, water out, oxygen rifle outer tube, the oxygen blast hole is formed, it is characterized in that: the bottom of shower nozzle oxygen blast body is a base, uniform 3-6 oxygen blast Taper Pipe on the circumferential direction of base, by die-forging forming is one, the built-in oxygen blast of oxygen blast Taper Pipe hole, the angle α of its axis and shower nozzle oxygen blast body axis is 7-18 °, the top of oxygen blast Taper Pipe is divided fluidic to fixedly connected with oxygen to finish by welding, guide water board is looped around the outside of the oxygen blast Taper Pipe on the shower nozzle oxygen blast body, with pipe in the oxygen rifle by being threaded.
The utility model die forging built-up type oxygen lance blow head, because the oxygen blast Taper Pipe of shower nozzle oxygen blast body divides fluid to fixedly connected by welding with oxygen, its manufacturing process is simple, qualification rate can have reasonable in design, the long characteristics of use poison life up to more than 95%.Its physical strength height, good heat conductivity, high pressure water enters in guide water board and oxygen rifle the water cooling chamber that forms between pipe and the shower nozzle oxygen blast body around the oxygen blast Taper Pipe by water-in, and shower nozzle oxygen blast body is carried out Forced water cooling but, good cooling results.
Embodiment:
Fig. 1 is a die forging built-up type oxygen lance blow head structural representation.
See Fig. 1, die forging built-up type oxygen lance blow head is to realize like this, be by shower nozzle oxygen blast body 1, guide water board 2, oxygen divides fluid 3, oxygen pipe 4, water-in 5, manage 6 in the oxygen rifle, water outlet 7, oxygen rifle outer tube 8 and oxygen blast hole 9 are formed, the bottom of shower nozzle oxygen blast body 1 is a base, uniform 3-6 oxygen blast Taper Pipe on the circumferential direction of base, by die-forging forming is one, the built-in oxygen blast of oxygen blast Taper Pipe hole 9, the angle α of its axis and shower nozzle oxygen blast body 1 axis is 7-18 °, the top of oxygen blast Taper Pipe divides fixedlying connected of fluid 3 to finish by welding with oxygen, and guide water board 2 is looped around the outside of the oxygen blast Taper Pipe on the shower nozzle oxygen blast body 1, with pipe in the oxygen rifle 6 by being threaded.High pressure water is entered by water-in 5, forms the water cooling chamber around the oxygen blast Taper Pipe in guide water board 2 and oxygen rifle between pipe 6 and the shower nozzle oxygen blast body 1, and shower nozzle oxygen blast body 1 is carried out Forced water cooling but, flows out good cooling results by water outlet 7 again.Oxygen rifle outer tube 8 is welded to connect with shower nozzle oxygen blast body 1, and oxygen pipe 4 divides fluid 3 to be fixedly connected by welding together with oxygen.
Claims (1)
1, a kind of die forging built-up type oxygen lance blow head, be by shower nozzle oxygen blast body, oxygen divides fluid, guide water board, the oxygen pipe, water-in, manage in the oxygen rifle, water outlet, oxygen rifle outer tube, the oxygen blast hole is formed, it is characterized in that: the bottom of shower nozzle oxygen blast body is a base, uniform 3-6 oxygen blast Taper Pipe on the base peripheral direction, by die-forging forming is one, the built-in oxygen blast of oxygen blast Taper Pipe hole, the angle α of its axis and shower nozzle oxygen blast body axis is 7-18 °, the top of oxygen blast Taper Pipe is divided fluidic to fixedly connected with oxygen to finish by welding, guide water board is looped around the outside of the oxygen blast Taper Pipe on the oxygen blast body, with pipe in the oxygen rifle by being threaded.
