Description
A kind of assembly type of the utility model center water-cooled oxygen blast shower nozzle belongs to steelmaking equipment, specifically makes steel a kind of supporting shower nozzle on the oxygen rifle, is made up of shower nozzle end, external diameter pipe, guiding water-stop sheet, the big end of oxygen lance and oxygen lance small end.
Existing a kind of casting center water-cooled oxygen blast shower nozzle, be the integral casting process manufacturing, on shower nozzle, form center water-cooled die cavity, foundry pattern and pouring technology are all had strict requirement, produce difficulty, product percent of pass is low, and shower nozzle end density is little, heat conductivility is poor, the easy thermal etching distortion of shower nozzle end face, and shower nozzle is short work-ing life.
The purpose of this utility model overcomes the deficiencies in the prior art exactly, the structure of a kind of assembly type center water-cooled oxygen blast shower nozzle is disclosed, have simple in structure, make and the characteristics of modular construction easily, can improve product percent of pass, reduce production costs, long service life, the overall economic efficiency height.
A kind of assembly type of the utility model center water-cooled oxygen blast shower nozzle, form by shower nozzle end, external diameter pipe, guiding water-stop sheet, the big end of oxygen lance and oxygen lance small end, the technical scheme that realizes the utility model purpose is: it is the oxygen blast hole that the big end front end of oxygen lance connects with the shower nozzle end, oxygen lance big end rear end and oxygen lance small end front end are fixedly connected, external diameter pipe and shower nozzle end are connected as a single entity, the guiding water-stop sheet is looped around outside the big end of oxygen lance, and the guiding water-stop sheet is provided with the connection rib-loop.
The utility model assembly type center water-cooled oxygen blast shower nozzle, the big end of shower nozzle end and oxygen lance can be impact briquetting, to increase density, be assemblied on the big end of oxygen lance and center water-cooled die cavity of formation between external diameter pipe and the shower nozzle end after the processing of guiding water-stop sheet system around the big end of oxygen lance, make easily, technology is simple, the product percent of pass height, and production cost is low; The big end of oxygen lance small end and oxygen lance can adopt welding to be fixedly connected, and easy construction connects quality and is guaranteed easily, and oxygen lance small end rear end directly connects with oxygen lance spraying oxygen pipe; The rib-loop that guiding is provided with on the water-stop sheet is used for connecting with the middle sleeve of high-pressure cooling water water inlet, and it is convenient to connect, the outer tube of water coolant water outlet can be directly and the external diameter pipe be fixedly connected, for example weld easy construction; Shower nozzle end density is big, good heat conductivity, and the shower nozzle end face is difficult for thermal etching distortion, shower nozzle long service life.In sum, the structure of the utility model assembly type center water-cooled oxygen blast shower nozzle has realized the purpose of this utility model preferably.
Below in conjunction with accompanying drawing the utility model assembly type center water-cooled oxygen blast shower nozzle and embodiment are described further.
Accompanying drawing is the structural profile synoptic diagram that first preferred embodiment is sprayed in the water-cooled oxygen blast of the utility model assembly type center.
A preferred embodiment as the utility model assembly type center water-cooled oxygen blast shower nozzle, as shown in the figure, water-cooled oxygen blast shower nozzle in the utility model assembly type center is made up of shower nozzle end 1, external diameter pipe 2, guiding water-stop sheet 3, the big end 5 of oxygen lance and oxygen lance small end 7, it is oxygen blast hole 6 that big end 5 front ends of oxygen lance connect with shower nozzle end 1, oxygen lance big end 5 rear ends and oxygen lance small end 7 front ends are fixedly connected, external diameter pipe 2 is connected as a single entity with shower nozzle end 1, and test-results shows, exists for external diameter pipe 2 diameters
Shower nozzle between 100～500 millimeters, the big end 5 of oxygen lance and oxygen lance small end 7 for the angle α of the axis of uniform 3～5, the big end 5 of oxygen lance and oxygen lance small end 7 and shower nozzle axis be 7～18 ° effective; Guiding water-stop sheet 3 is looped around outside the big end 5 of oxygen lance, guiding water-stop sheet 3 is provided with and connects rib-loop 4, conveniently carrying out rib-loop with high-pressure cooling water water inlet middle sleeve is connected, high-pressure cooling water is entered the center water-cooled die cavity around the big end 5 of oxygen lance that forms by between guiding water-stop sheet 3 and external diameter pipe 2 and the shower nozzle end 1 by water-in 11, big end 5 of oxygen lance and shower nozzle end 1 are carried out Forced water cooling but again by water outlet 12 outflows, good cooling results.
Consider when oxygen lance spraying oxygen pipe directly connects with oxygen lance small end 7 rear ends, shower nozzle can produce the moderate finite deformation internal stress when elevated temperature heat expands, cause structure deteriorate, a preferred embodiment as the utility model assembly type center water-cooled oxygen blast shower nozzle, as shown in drawings, preferably also have an inner sliding sleeve 9 to be fixedly connected and be communicated with, on inner sliding sleeve 9 outer walls, be inlaid with wear ring 10, for example " O " type wear ring in the rear end of oxygen lance small end 7 and with oxygen lance small end 7 and the big end 5 of oxygen lance.During use with inner sliding sleeve 9 sleeves within oxygen lance spraying oxygen pipe for being slidingly connected 8 blocked center water-cooled die cavity tops, inner sliding sleeve bottom.Like this, when shower nozzle thermal expansion at high temperature is out of shape, just can absorb distortion by the slip of inner sliding sleeve 9, wear ring 10 guarantees sealing, can not produce the distortion internal stress between shower nozzle and the oxygen lance spraying oxygen pipe, favourable raising life-span of oxygen lance.
For the manufacturing enterprise that possesses strong braze-ability, water-cooled oxygen blast shower nozzle in the utility model assembly type center can also be that big end 5 of said oxygen lance and oxygen lance small end 7 are one, front end is fixedly connected with the oxygen blast hole on soldering processes and the shower nozzle end 1, thereby simplifies shower nozzle end 1 punch forming process and save the big end 5 of oxygen lance and oxygen lance small end 7 operation that is fixedly connected.
