Abstract
A kind of Novel slag removal device improving desulphurization and slag skimming efficiency, to win in succession from above (1) and bottom band plate (2) is composed of a fixed connection, it is characterized in that: above win in succession (1) is for narrow boards, bottom band plate (2) is wide plate, on to win in succession (1) and angle between bottom band plate (2) is 150-170 to spend, be provided with the connecting hole (3) of a slag removal device and slag removal machine on upper top of winning (1) in succession.This kind of slag removal device design improves slag removal device and molten iron slag contact area under identical depth of penetration condition, change angle of skimming, reduce the stirring of slag removal device to molten iron, while improve desulphurization and slag skimming efficiency, reduce iron loss of skimming, significant to steel making working procedure cost efficiency.
Description
Technical field
The utility model belongs to ferrous metallurgy steelmaking technical field, particularly relates to the device that molten iron pretreatment desulfurizing operation is skimmed.
Background technology
Molten iron pretreatment desulfurizing operation major function for carry out desulfurization process to molten iron, as required for converter provides the molten iron of different sulphur content.Current domestic main flow Desulphurization of Pig Iron mainly contains magnesium granule blowing method and KR doctor treatment, generally adopts " skim before de--desulfurization process-Tuo then skim " technique.Skimming before de-is the high-sulfur slag carried to remove molten iron, reduces sorbent consumption, and skimming after de-is form slag to remove desulfurization process, and avoid molten iron to return sulphur phenomenon, therefore molten iron drossing is stablized most important for desulfurization treatment effect.Steelmaking Project factory finds in blowing process and the production practice of KR method, and slag removal device is key constraints as molten iron drossing machine important component part for raising efficiency of skimming.
Summary of the invention
The purpose of this utility model is that providing a kind of changes angle of skimming by increasing slag removal device and slag contact surface area, add the contact area with slag, reduces slag removal device to the stirring of molten iron, improves the Novel slag removal device of desulphurization and slag skimming efficiency.
Realizing the technical scheme that the purpose of this utility model takes is: this slag removal device is won in succession from above and bottom band plate is composed of a fixed connection, it is characterized in that: above win in succession as narrow boards, bottom band plate is wide plate, on to win in succession and angle between bottom band plate is 150-170 to spend, be provided with the connecting hole of a slag removal device and slag removal machine on upper top of winning in succession.
During use, by the connecting hole on above winning in succession, slag removal device is fixed on slag removal machine.This kind of slag removal device design improves slag removal device and molten iron slag contact area under identical depth of penetration condition, change angle of skimming, reduce the stirring of slag removal device to molten iron, iron loss of skimming is reduced while improve desulphurization and slag skimming efficiency, significant to steel making working procedure cost efficiency, improve economic benefit.The utility model technique is simple, reasonable in design, can meet the processing requirement that molten iron pretreatment desulfurizing operation improves efficiency of skimming.After invention, this kind of slag removal device achieves the object improving skim efficiency and cost efficiency smoothly.
Accompanying drawing explanation

In figure, 1, upper plate; 2, bottom band plate; 3, connecting hole; 4, hot metal ladle slag interface.
Embodiment
The utility model be win in succession from above 1 and bottom band plate 2 be composed of a fixed connection, above win 1 in succession for narrow boards, bottom band plate 2 is wide plate, and the angle of above winning in succession between 1 and bottom band plate 2 is 150-170 to spend, upper win in succession 1 top be provided with the connecting hole 3 of a slag removal device and slag removal machine.As shown in Figure 2 be the schematic diagram skimmed in slag removal device side, slag removal device contacts with hot metal ladle slag interface 4, skims.This kind of slag removal device design both can be used in Desulfurization by injecting method and also can be used in KR method sulfur removal technology.By increasing the principle of slag removal device and slag contact surface area, the original slag removal device profile arrangement of creationary change, operation room changes angle of skimming, thus improves efficiency of skimming.Simultaneously owing to adding the contact area with slag, reduce the stirring of slag removal device to molten iron, the iron loss that indirectly reducing skims brings, economic benefit is obvious.
Claims (1)
1. one kind is improved the Novel slag removal device of desulphurization and slag skimming efficiency, to win in succession from above (1) and bottom band plate (2) is composed of a fixed connection, it is characterized in that: above win in succession (1) is for narrow boards, bottom band plate (2) is wide plate, on to win in succession (1) and angle between bottom band plate (2) is 150-170 to spend, be provided with the connecting hole (3) of a slag removal device and slag removal machine on upper top of winning (1) in succession.
