Benefits of technology

The technical effects described by this inventor are that they have longer lifespan for their converters while also improving coolability without sacrificing performance or causing damage during use due to high temperatures caused by poorly cooled parts such as an oxidizing gas injected into molten metal baths inside the vessel's hearth. Additionally, these improvements lead to better control over heat transfer within the system, resulting in more efficient energy utilization compared to traditional methods like lining up pipelines on top of them. Overall, there will result in higher quality products from metals produced through the transformation process.

Problems solved by technology

This patented describes different ways how well-performed converters are used during oxidative metallurgy (Oxide Steel). One aspect being addressed involves improving their efficiency at producing iron due to better control on both the amount of gas supplied or produced from them compared with traditional methods like blast furnace smoking. Another aspect focuses around prevention of damage caused by excessive temperatures inside these devices while still providing effective heat transfer capabilities.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0022] A central water-cooled converter oxygen lance nozzle, such as figure 1 As shown, it includes a nozzle main body composed of an inner pipe 6, a middle pipe 7 and an outer pipe 8. The inner pipe 6 is a water inlet channel 1, and the annular seam between the inner pipe 6 and the middle pipe 7 is an oxygen channel 3, and the middle pipe The annular seam between the pipe 7 and the outer pipe 8 is the water return channel 5; the oxygen channel 3 communicates with the oxygen nozzle 4 arranged at the bottom of the shower head body, and the water inlet channel 1 passes through the water provided on the shower head body. Hole 2 communicates with return channel 5 . The number of the oxygen injection holes 4 is 3 holes, 4 holes, 5 holes, 6 holes, 7 holes, 8 holes, 9 holes or 10 holes. A central water-cooled converter oxygen lance body matched with the nozz

Abstract

The invention relates to a center water-cooling convertor oxygen lance spraying head which is good in water-cooling effect, long in service life, and simple in manufacturing process. The spray head comprises an inner pipe, a middle-layer pipe and an outer pipe, wherein the inner pipe is a water entry, the water entry is arranged at the center of the oxygen lance spraying head, the lower side of the water entry is communicated with a water return channel, the circumferential seam between the middle-layer pipe and the outer pipe is the water return channel, the circumferential seam between the inner pipe and the middle-layer pipe is an oxygen channel, the oxygen channel is communicated with oxygen spray holes, the oxygen spray holes are formed at the periphery of the inner pipe, and the number of the oxygen spray holes is 3, 4, 5, 6, 7, 8, 9 or 10. The spraying head is suitable for various convertor oxygen steelmaking equipment, can carry out low-gun-position operation, is strong in oxygen penetrating capacity, good in stirring effect, rapid in slagging and low in splashing, prolongs the furnace life, lowers the FeO content in the slag, and lowers the steel consumption.
