Abstract
The utility model relates to an oxygen side blown converter, comprising a furnace casing, a furnace liner, and an oxygen lance. The furnace liner and the furnace casing are fitted, both of the horizontal sections are elliptical, and the oxygen lance is penetrated through the side wall of the furnace casing and the furnace liner. The utility model adopts ellipsoidal structure on the furnace casing and the furnace liner, eliminating thermal stress centralization largely, prolonging the service life of the furnace casing and the furnace liner, and creating conditions for macro-scale development of the oxygen side blown converters.
Description
The utility model relates to kind of a steel melting furnace, particularly oxygen side blown converter.At present, oxygen side blown converter commonly used in the STEELMAKING PRODUCTION mostly is the square furnace shell, because its steel construction corner connection is more, thermal stresses is big, thereby often causes the bight cracking to influence the steel construction life-span.In addition, square furnace shell can only be repaiied stove with the square brick, and this mode of building by laying is not owing to there is radially control, causes that to fall brick in the production serious, and furnace life is low, and workman's fettling labour intensity is big.The square oxygen side blown converter exists simultaneously also that the fire door size is uncontrollable, and the molten steel streamline is unreasonable, shortcomings such as fluidity molten steel difference.These factors are directly restricting the development that oxygen side blown converter maximizes.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of rational in infrastructure, oxygen side blown converter that can prolong furnace shell and furnace lining work-ing life is provided, for the large scale development of oxygen side blown converter creates conditions.
The purpose of this utility model is achieved by the following technical solution: comprise furnace shell (1), furnace lining (2), oxygen rifle (3) in the composition of the present utility model, furnace lining and furnace shell match, the horizontal section of the two is oval, and oxygen rifle (3) penetrates in the stove from the sidewall of furnace shell (1) and furnace lining (2).
The utility model adopts oval structure with furnace shell, furnace lining, can eliminate thermal stresses significantly and concentrate, and can prolong furnace shell and furnace lining work-ing life, for the large scale development of oxygen side blown converter has been created condition.
Fig. 1 is the utility model embodiment vertical section structure synoptic diagram.
Fig. 2 is the utility model embodiment cross section 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 furnace shell (1), furnace lining (2), oxygen rifle (3), water-cooled converter nose (4).For making things convenient for mechanical workout to make, the horizontal section of furnace lining and furnace shell is made for the ellipse of four hearts, four arcs, the two matches.Oval minor axis and major axis ratio are 0.6--0.9.Oxygen rifle (3) penetrates in the stove from the sidewall of furnace shell (1) and furnace lining (2).For control fire door shape, improve thermo-efficiency, add oval water-cooled converter nose (4) at fire door.
Claims (5)
1, a kind of oxygen side blown converter with furnace shell (1), furnace lining (2), oxygen rifle (3), furnace lining and furnace shell match, and oxygen rifle (3) penetrates in the stove from the sidewall of furnace shell (1) and furnace lining (2), and the horizontal section that it is characterized in that furnace lining and furnace shell is for oval.
2, the oxygen side blown converter according to claim 1 is characterized in that adding oval water-cooled converter nose (4) at fire door.
3,, it is characterized in that said ellipse is that four hearts, four arcs constitute according to claim 1 or 2 described oxygen side blown converters.
4,, it is characterized in that the minor axis of said ellipse and major axis ratio are 0.6--0.9 according to claim 1 or 2 described oxygen side blown converters.
5, the oxygen side blown converter according to claim 3 is characterized in that the minor axis of said ellipse and major axis ratio are 0.6--0.9.
