Abstract
The utility model relates to a steel making device for a metallurgy converter, particularly a jet head of an oxygen lance used by a converter. The utility model has the technical scheme that a mixed hole type multiporous oxygen jet head is composed of an oxygen lance head (1) and a blowing hole, a Raval hole (2) is bored in the center of the oxygen lance head of which the circumference has a plurality of cylindrical holes (3, 4) or convex expansion holes. When the utility model carries out converting, the big Raval hole (2) bored in the center of the oxygen lance head is mainly used for decarbonizing and heating, the cylindrical holes (3, 4) bored on the circumference of oxygen lance head are mainly used for melting slag, as a result, the problems of slag melting, decarbonizing and heating are solved completely in the process of blowing oxygen for making steel by the converter. The utility model has the advantages of reasonable structure, convenient operation, high converting efficiency, etc.
Description
The utility model relates to a kind of metallurgical converter steelmaking equipment, particularly oxygen lance spray nozzle for converter.
At present, people mostly are Lavalle type Multi-pore oxygen lance nozzle at the oxygen lance blow head that metallurgical converter uses, and this shower nozzle solution slag and the relation that carbon elimination heats up well in operating process influence the effect that blows.
The purpose of this utility model provides a kind of mixing pass Multi-pore oxygen lance nozzle, solves to bessemerize the contradiction of changing in the process between slag and the carbon elimination intensification, improves the blowing effect.
The purpose of this utility model is achieved by the following technical solution: comprise rifle head, injection hole in the composition of the present utility model, the centre of rifle head is provided with type hole, Lavalle, is provided with some straight barrel types hole or protuberant expanding type hole all around.
Adopt the current period during novel the blowing, type hole, rifle head intermediary Lavalle is mainly used in carbon elimination and heats up, straight barrel type all around or being mainly used in of protuberant expanding type hole slag, like this, the problem that change slag in the converter steelmaking oxygen blast process and carbon elimination heat up can be satisfactorily resolved, thereby improves the blowing effect.
The utlity model has rational in infrastructure, easy to use, improve characteristics such as blowing effect.
Accompanying drawing is the utility model example structure synoptic diagram.
Below with reference to accompanying drawings, further specify the utility model by embodiment.
In an embodiment, the utility model is made up of rifle head (1), injection hole, and the centre of rifle head is provided with big type hole, Lavalle (2); Be provided with some straight barrel types hole (3,4) all around, when adopting the utility model to blow, rifle head intermediary type hole, big Lavalle (2) is mainly used in carbon elimination and heats up, straight barrel type hole all around (3,4) being mainly used in slag, like this, the problem that change slag in the converter steelmaking oxygen blast process and carbon elimination heat up can be satisfactorily resolved, thereby improves the blowing effect.
Claims (1)
1, a kind of mixing pass Multi-pore oxygen lance nozzle with rifle head (1), gun hole is characterized in that the centre of said rifle head is provided with type hole, Lavalle (2), is provided with some straight barrel types hole (3,4) or protuberant expanding type hole all around.
