Abstract
The utility model discloses a continuous casting middle ladle capable of conducting non-oxidation protection casting. The continuous casting middle ladle comprises a middle ladle body, wherein an argon blowing pipe is arranged on one side face of the middle ladle body; an opening at the upper end of the argon blowing pipe is connected with a nozzle; gas injection holes are formed around and in the bottom face of the nozzle; and the nozzle is positioned in the center of the upper part of the middle ladle body. According to the continuous casting middle ladle, after an impact zone argon shield casting technology is adopted, the nitrogen content of a casting blank is reduced effectively, and the quality of the casting blank is improved.
Description
Technical field
The utility model relates in the continuous casting of the carried out non-oxidation protective casting that uses in a kind of steel industry and wrapping.
Background technology
Through the molten steel of first refining and refining, owing to contacting with airborne oxygen, refractory material, slag the secondary oxidation that molten steel occurs, its product partly is trapped in and causes non-metallic inclusion in steel in middle bag casting process, and the cleannes of steel are reduced.
Summary of the invention
The purpose of this utility model is to provide in a kind of continuous casting that carries out the non-oxidation protective casting and wraps, and it can prevent the secondary oxidation of molten steel effectively, reduces the nitrogen content of strand, improves slab quality.
The purpose of this utility model is to realize like this; wrap in a kind of continuous casting that carries out the non-oxidation protective casting; comprise middle bag body; in a side of middle bag body, an argon purge pipe is being set; the upper end open place of argon purge pipe is connecting a nozzle; fumarole is being set respectively on the surrounding of nozzle and bottom surface, and nozzle is arranged in bag body central upper portion place.
The utility model uses special-purpose Argon pipe centering bag impact zone liquid steel level to carry out the argon purge protection at impact zone, thereby can effectively prevent the secondary oxidation of molten steel, reduces the nitrogen content of strand, improves slab quality.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
Wrap in a kind of continuous casting that carries out the non-oxidation protective casting; as shown in Figure 1; comprise middle bag body 4; in a side of middle bag body 4, an argon purge pipe 1 is being set; the upper end open place of argon purge pipe 1 is connecting a nozzle 2; fumarole is being set respectively on the surrounding of nozzle 2 and bottom surface, is being conducive to like this enlarge the purging area.Nozzle 2 is arranged in bag body 4 central upper portion places, and nozzle 2 is near middle bag long nozzle 3.After the utility model adopted impact zone argon for protecting pouring technology, the nitrogen content of strand was effectively reduced, and has improved slab quality.
