Abstract
The utility model belongs to the field of metallurgy, discloses a device for improving the purity degree of molten steel, and relates to a large-ladle drainage sand eliminating device. The large-ladle drainage sand eliminating device comprises argon air pipes, a drainage groove and an overflow groove, wherein the drainage groove is formed in one side below a large-ladle sleeve in an inclined mode, the overflow groove is formed in one side below the drainage groove, the number of the argon air pipes is two, the argon air pipes are located on the two sides of a large-ladle impaction area respectively, a nozzle is connected to each argon air pipe, and the nozzles align with drainage sand flowing down from the large-ladle sleeve. The large-ladle drainage sand eliminating device is simple and reasonable in structure and convenient to use, enables the drainage sand in a large ladle to be completely led into the overflow groove as far as possible under the drainage effect of argon air before the drainage sand enters a medium ladle, improves the purity degree of molten steel in the medium ladle, and improves the interior quality of a casting blank.
Description
Technical field
The utility model belongs to the device that is used for improving the molten steel degree of purity of field of metallurgy, a kind of big bag drainage sand scavenge unit specifically.
Background technology
Current steel market is increasingly competitive, high-quality strand has become in the weight of Business survival factor heavy, continuous casting is one of key of iron and steel enterprise's control slab quality, and the field trash that can reduce strand to greatest extent is an important step of continuous casting control strand internal soundness; Be converted into solid-state pans (middle bag) as molten steel by liquid key operation is played in the control of its field trash, therefore the control that the degree of purity of molten steel is produced the high-quality strand to continuous casting in the middle bag will be played conclusive effect.
At present, molten steel in the big bag wraps impact zone in excessive water-coating port directly enters, drainage sand in the big bag directly enters Zhong Bao, when particularly changing bag at every turn, there is a large amount of drainage sand to pour in the Zhong Bao molten bath, in casting process, these field trashes have little time come-up and just are brought in the strand, have a strong impact on the internal soundness of strand.
The utility model content
Technical problem to be solved in the utility model is, proposes a kind of big bag drainage sand scavenge unit, and the effect with the drainage of argon wind before the drainage sand in wrapping greatly can being wrapped in entering is all introduced it in overflow launders, with Baogang's water degree of purity in improving.
The technical scheme that the utility model solves above technical problem is:
Big bag drainage sand scavenge unit, comprise argon airduct, drainage trough and overflow launder, drainage trough tilts to be located at a side of big canning tube below, overflow launder is located at a side of drainage trough below, the argon airduct is provided with two-way, lay respectively at big bag impact zone both sides, be connected to nozzle on the argon airduct, the drainage sand that nozzle alignment flows down from big canning tube.
Like this, the argon gas that sprays from the argon airduct blows drainage sand, forms wind sand, introduces drainage trough, slips into the ladle overflow launder.
The technical scheme that the utility model further limits is:
Aforesaid big bag drainage sand scavenge unit, wherein said nozzle becomes 15 ° of angles with ground, and two-way argon airduct becomes hexagonal angle.
The beneficial effects of the utility model are: the utility model is simple and reasonable, easy to use, can in entering, before the bag, all introduce it in overflow launder with the effect of argon wind drainage the drainage sand in wrapping greatly as far as possible, Baogang's water degree of purity in the raising improves the strand internal soundness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the distribution schematic diagram of the utility model argon airduct.
The specific embodiment
Embodiment 1
Present embodiment is a kind of big bag drainage sand scavenge unit, structure as shown in Figure 1, comprise argon airduct 2, drainage trough 1 and overflow launder 3, drainage trough 1 tilts to be located at a side of big canning tube 5 belows, overflow launder 3 is located at a side of drainage trough 1 below, argon airduct 2 is provided with two-way, as shown in Figure 2, argon airduct 2a and argon airduct 2b lay respectively at big bag impact zone 4 both sides, be connected to nozzle on the argon airduct 2, the drainage sand 6 that nozzle alignment flows down from big canning tube, nozzle become 15 ° of angles with ground, argon airduct 2a becomes hexagonal angle with argon airduct 2b.
The argon gas that sprays from the argon airduct blows drainage sand, forms wind sand, introduces drainage trough, slips into the ladle overflow launder.Water and change bag and the time open argon wind and the drainage sand blast is played atomizing finally introduced in the overflow launder by drainage trough opening at every turn.The utility model can before the bag, all be introduced it drainage sand in wrapping greatly in the overflow launder with the effect of argon wind drainage in entering as far as possible, and Baogang's water degree of purity in the raising improves the strand internal soundness.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. wrap drainage sand scavenge unit greatly, it is characterized in that: comprise argon airduct, drainage trough and overflow launder, described drainage trough tilts to be located at a side of big canning tube below, described overflow launder is located at a side of described drainage trough below, described argon airduct is provided with two-way, lay respectively at big bag impact zone both sides, be connected to nozzle on the described argon airduct, the drainage sand that described nozzle alignment flows down from described big canning tube.
