The center-water-cooling oxygen lance nozzle for the converter has the advantages of good water cooling effect, long service life and simple manufacturing process. The center-water-cooling oxygen lance nozzle comprises an inner tube, a middle layer tube and an outer tube, wherein the inner tube serves as a water inlet passage, the water inlet passage is located at the center of the oxygen lance nozzle, the lower part of the water inlet passage is communicated with a water return passage, an annular seam between the middle layer tube and the outer tube serves as the water return passage, an annular seam between the inner tube and the middle layer tube serves as an oxygen passage, and the oxygen passage is communicated with oxygen spray holes. The oxygen spray holes encircle the periphery of the inner tube, and the number of the oxygen spray holes is 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10. The center-water-cooling oxygen lance nozzle is applicable to various converter oxygen steelmaking devices; the lower lance position operation can be carried out, the oxygen penetration capability is strong, the stirring effect is good, the slagging is fast, and the splash is little; and the service life of a converter body is prolonged, the content of FeO in slag is reduced, and the consumption of iron and steel materials is reduced.
Description
Technical field
The utility model belongs to the converter steeling technology field, particularly relates to a kind of central water-cooling Oxygen Lance Nozzle for Converter.
Background technology
Oxygen steel making process has a series of superiority, and therefore, the whole world has all adopted oxygen steelmaking.Converter is topmost oxygen steelmaking equipment.The oxygen rifle is the oxygen blast instrument of converter, and the property relationship of oxygen rifle is to a series of technico-economical comparisones such as the Yield and quality of steel, cost, raw materials consumptions; Therefore, can say that the oxygen rifle is the key equipment of converter oxygen steelmaking.
The performance of converter oxygen gun mainly comprises two aspects, and one is oxygen blown effect, and another is the height in life-span.
Converter oxygen gun is comprised of rifle body and shower nozzle two portions, and the performance of oxygen rifle is mainly embodied by the performance of shower nozzle.The lance body structure of converter oxygen gun is comprised of three layers of weldless steel tube.At present, existing all converter oxygen guns, its inner layer steel pipe all is the oxygen channel of oxygen circulation, circumferential weld between inner layer steel pipe and the middle level steel pipe is the water entry of water coolant, circumferential weld between middle level steel pipe and the outer layer pipe is the backwater channel of water coolant, shower nozzle also is so, as shown in figures 1 and 3.The shortcoming of this kind structure: the one, the water-cooled effect is relatively poor, and shower nozzle does not reach the high life, and another is the textural defect of shower nozzle, causes the manufacturing process of shower nozzle complicated.
Summary of the invention
For the deficiency on existing converter oxygen gun and the nozzle structure, the utility model provides a kind of good water-cooling effect, long service life, the simple central water-cooling converter oxygen gun of manufacturing process and shower nozzle.
To achieve these goals, the utility model adopts following technical scheme:
A kind of central water-cooling Oxygen Lance Nozzle for Converter, it comprises inner tube, middle tube and outer tube, it is characterized in that, inner tube is water entry, water entry is at the center of oxygen lance blow head, is communicated with backwater channel below the water entry, and the circumferential weld between middle tube and the outer tube is backwater channel, circumferential weld between inner tube and the middle tube is oxygen channel, and oxygen channel communicates with the oxygen spray orifice.Described oxygen spray orifice is centered around around the inner tube, and the number of oxygen spray orifice is 3 holes or 4 holes or 5 holes or 6 holes or 7 holes or 8 holes or 9 holes or 10 holes.
Comprise the oxygen gun body that is comprised of inner tube, middle tube and outer tube that cooperates with this central water-cooling Oxygen Lance Nozzle for Converter, described inner tube is water entry, and the circumferential weld between inner tube and the middle tube is oxygen channel, and the circumferential weld between middle tube and the outer tube is backwater channel.
The beneficial effects of the utility model:
1, owing to water-cooled centered by the Oxygen Lance Nozzle for Converter of the present utility model, so good water-cooling effect, the shower nozzle life-span is long;
2, because the shower nozzle life-span is long, can hang down the rifle bit manipulation, the oxygen penetration ability is strong, stirs, and it is fast to change slag, and splash is little; Improve converter life, reduce FeO content in the slag, reduce iron and steel stock consumption;
3, because the shower nozzle life-span is long, improve the operating rate of converter steelmaking, improved the output of steel, reduced the production cost of steel-making;
4, because the structure of shower nozzle is easy to carry out turning processing, simplified the process for machining and manufacturing of shower nozzle.
