Abstract
The utility model discloses an oxygen lance nozzle with a vertical insertion port connection between forged copper and cast copper and belongs to the technical field of converter steelmaking, wherein the oxygen lance nozzle consists of an external forged piece and an internal cast piece which are connected through a vertical insertion port and are brazed into a whole; the external forged piece is formed by forging T1 or T2 grade red copper; and the internal cast piece is formed by casting a copper alloy. The oxygen lance nozzle disclosed by the utility model has the advantages of long service life, good converting effect, high safety and low cost.
Description
Technical field
The utility model belongs to the converter steeling technology field, the oxygen lance blow head that the vertical socket of particularly a kind of forge copper cast copper connects.
Background technology
The oxygen rifle is a most important oxygen blowing apparatus in the convertor steelmaking process, and oxygen lance blow head is the topmost spare part of converter oxygen gun.The oxygen blast effect of oxygen rifle depends primarily on the performance of shower nozzle.
Existing oxygen lance blow head mainly contains two kinds: casting oxygen lance blow head and forging and pressing assembling oxygen lance blow head.The advantage of casting shower nozzle is: rational in infrastructure, the shape of any complicacy can both cast out; And manufacturing cost is lower, is fit to produce in enormous quantities; Shortcoming is: purity is low, density is low, heat conductivility is poor, and defectives such as the pore that in the process of casting, produces, loose, crackle influence work-ing life; Oxygen bore outlet position corrode is very fast, influences the blowing effect of oxygen rifle.The advantage of forging and pressing assembling shower nozzle is: dense materials, high, the good heat conductivity of purity, and the work-ing life of shower nozzle is longer; Shortcoming is: the parts of forming shower nozzle are many, are example with five hole shower nozzles, nearly 11 of building blocks, and complete processing is complicated; Cost of manufacture is high, and process velocity is slow, and the weld seam of shower nozzle is more, is example with five hole shower nozzles; Weld seam is 13 places nearly, have potential safety hazard, in the production process, and easy occurrence of waste.
Summary of the invention
To the shortcomings and deficiencies of existing oxygen lance blow head, the utility model provides a kind of production technique simple, long service life, and safety performance is good, the oxygen lance blow head that the vertical socket of the forge copper cast copper that cost is low connects.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: the oxygen lance blow head that the vertical socket of forge copper cast copper connects, form by outer forging and interior foundry goods, and both link together through vertical socket, and soldering is an one-piece construction.
Said outer forging adopts T1 or the forging and pressing of T2 level red copper to form.
Oxygen pipe, branch oxygen dish, oxygen post, guide water board, middle water pipe in foundry goods comprises in said, each several part adopts the copper alloy casting as a whole.
The oxygen lance blow head that the vertical socket of the forge copper cast copper that the utility model provides connects, the oxygen hole is set to three holes, four holes, five holes, the 4 kinds of structure formations in six holes.
The beneficial effect of the utility model is:
⑴ the outer forging that the oxygen lance blow head of the utility model contacts with flame adopts the forging and pressing of high purity red copper to form, and its purity is high, density is big, metallographic structure is fine and close, good heat conductivity, and the corrode speed in oxygen hole is slow, the long service life of shower nozzle, oxygen blast stable performance;
⑵ cast casting becomes an integral body in, has eliminated the weld seam between each parts, has simplified nozzle structure and complete processing, has improved production rate and yield rate, has eliminated potential safety hazard, has reduced production cost simultaneously;
⑶ the vertical socket of employing is connected between outer forging and the interior foundry goods, and production technique is simple.
Description of drawings
Fig. 1 is the oxygen lance blow head structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1;
Among the figure: 1 outer forging, 2 interior foundry goods, 2a oxygen post, water pipe among the 2b, 2c guide water board, 2d divide the oxygen dish, oxygen pipe in the 2e, 3 vertical sockets, 4 oxygen holes.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The oxygen lance blow head that the vertical socket of forge copper cast copper connects is made up of with interior foundry goods 2 outer forging 1, and both link together through vertical socket 3, and soldering is an one-piece construction.
It is that 99.97% T1 level red copper forging and pressing form that outer forging 1 adopts purity.
Claims (3)
1. the oxygen lance blow head that connects of the vertical socket of a forge copper cast copper, it is characterized in that: this oxygen lance blow head is made up of outer forging and interior foundry goods, and both link together through vertical socket, and soldering is an one-piece construction.
2. the oxygen lance blow head that the vertical socket of forge copper cast copper according to claim 1 connects is characterized in that said outer forging adopts T1 or the forging and pressing of T2 level red copper to form.
3. the oxygen lance blow head that the vertical socket of forge copper cast copper according to claim 1 connects is characterized in that said interior foundry goods comprises interior oxygen pipe, divides oxygen dish, oxygen post, guide water board, middle water pipe, and each several part adopts the copper alloy casting as a whole.
