Abstract
The utility model provides a spray head in threaded connection for forged oxygen lances, which relates to the technical field of converter steel making. An end cover of the spray head is formed by forging a red copper plate, and is connected with an oxygen post of the spray head in the mode of threaded connection. The oxygen post is welded with a forged oxygen pipe disc, and is matched with a forged water blocking plate. The utility model has the characteristics of the adoption of the threaded connection mode, simple processing technology, low cost, safety, reasonable structure, high purity, high strength, stable performance and long service life of the spray head.
Description
The utility model relates to the converter steeling technology field.
At present, the oxygen lance blow head of China mainly is to form with industrial red copper monoblock casting.The casting shower nozzle is owing to be subjected to the restriction of foundry engieering technology, the purity of shower nozzle, density, heat conductivility are difficult to satisfy service requirements, casting flaws such as the pore that produces in the castingprocesses, loose, crackle, burr, overlap, inevitably have influence on the water-cooled and the heat conduction of shower nozzle, the life-span of shower nozzle is reduced.Particularly oxygen bore outlet position distortion has in use influenced the blowing effect of oxygen rifle.
In view of the problem that the casting oxygen lance blow head exists, developed the assembly type oxygen lance blow head abroad.This shower nozzle is made up of oxygen hose dish, oxygen post, shelves water plate, outer tube and end cap.Except that outer tube, all the other four parts all are stamping parts, combine through turning, soldering.Though this shower nozzle life-span height, it is effective to blow, the complete processing complexity, and weld seam is more, has potential safety hazard.Between oxygen post and oxygen hose dish and the end cap, be to adopt the soldering of money base scolder together, manufacturing cost is higher.So, also fail so far to apply in China.
The purpose of this utility model is at the technical deficiency of currently available products, and a kind of Rational structure that promptly has is provided, and is again the novel center water cooled oxygen lance shower nozzle that adopts forging method processing.
The technical solution of the utility model:
A kind of forging oxygen lance blow head of forming by shower nozzle end cap, water eliminator, outer tube, middle pipe, oxygen post, oxygen hose dish, interior pipe and " O " type rubber ring that is threaded, it is characterized in that the shower nozzle end cap links together with the oxygen post threadably, the oxygen hose dish of oxygen post and forging molding welds together, and is equipped with the water eliminator of forging molding.
Characteristics of the present utility model are to adopt thread connecting mode, and complete processing is simple, cost is low, safe and reliable, and rational in infrastructure, purity is high, density is high, intensity is high, stable performance, the shower nozzle life-span is long.
Accompanying drawing 1 is to be threaded to forge the oxygen lance blow head assembling section.Accompanying drawing 2 is vertical views of this shower nozzle.
Provide following embodiment in conjunction with the accompanying drawings:
The forging oxygen lance blow head that is threaded can be made into multiple structural shapes such as 3 holes, 4 holes, 5 holes, 6 holes, 7 holes, 8 holes.Be illustrated (seeing Fig. 1, Fig. 2) with 4 hole shower nozzle embodiment.The forging oxygen lance blow head that is threaded is made up of end cap 1, water eliminator 2, outer tube 3, middle pipe 4, oxygen post 5, oxygen hose dish 6, interior pipe 7 and " O " type rubber ring 8.Shower nozzle end cap 1 is to use copper sheet forging molding, Internal Threading, be connected with the oxygen post 5 of steel,, with when oxygen post 5 is threaded the water eliminator 2 and the oxygen post 5 of forging molding assembled at end cap 1, weld together with oxygen hose dish 6 again with the steel plate forging molding.With interior pipe 7 and 6 welding of oxygen hose dish, middle pipe 4 is threaded with water eliminator 2 at last, and outer tube 3 welds mutually with end cap 1, puts " O " type rubber ring 8 of sealing usefulness, and finishing is threaded forges whole complete processings of oxygen lance blow head.
Screw-jointed forged oxygen-lance nozzle is compared with the casting shower nozzle, the purity height of product, density height, strong Degree height, stable performance, shower nozzle life-span are long. Compare thread connecting mode, processing with the assembly type shower nozzle Technology is simple, cost is low, safe and reliable.
