Abstract
It the utility model is related to a kind of converter tapping slag isolating construction, including converter, ladle and slag ladle, ladle is arranged on the lower section of converter, form steel stream between converter taphole and ladle, the stove skirtboard side of converter is provided with Argon pipe, and the distance of Argon pipe and tapping hole is 25cm -35cm, Argon Guan Yugang streams are in 50 ° -60 ° angles, Argon pipe by connection by metal hose to outside source of the gas, is purged to the steel stream in latter stage of tapping by Argon pipe again, separates slag.The utility model is purged to end steel stream, and lighter bits are purged out outside ladle into slag ladle, and steel stream is unaffected to be gone successively in ladle, and it is more preferable especially to mix out effect to tapping later stage slag.
Description
Technical field
Converter installation is the utility model is related to, specifically a kind of slag steel isolating construction being used for after Converter Skimming.
Background technology
Floating plug proportion stability is very big by raw material proportioning and technogenic influence, especially lack of uniformity, plus furnace lining facet
It is uneven to cause tapping process slag, later stage slag to mix out, bad lift furnace zone slag of pushing off the slag effect etc..
Utility model content
Technical problem to be solved in the utility model provides a kind of more reliable and more stable for above-mentioned prior art
Prevent slag from flowing into the structure of molten steel.
The technical scheme in the invention for solving the above technical problem is：A kind of converter tapping slag isolating construction, bag
Converter, ladle and slag ladle are included, ladle is arranged on the lower section of converter, and steel stream, the stove of converter are formed between converter taphole and ladle
Skirtboard side is provided with Argon pipe, and the distance of Argon pipe and tapping hole is 25cm -35cm, and Argon Guan Yugang streams are in 50 ° -60 °
Angle, Argon pipe by connection by metal hose to outside source of the gas, are purged to the steel stream in latter stage of tapping by Argon pipe again, make steel
Slag separates.
Preferably, the Argon pipe is that bore grows 10-15cm, 1.5-2.5cm of width, 1-1.5m of length steel pipe.I.e.
Using the gas blow pipe of prolate type mouth, steel stream is not influenceed while allowing lightweight slag fully to float.
Compared with prior art, the utility model has the advantage of：The utility model is that converter tapping prevents the mixed punching of slag
Enter the guarantee of molten steel, especially Special Steel Enterprise is controlled converter slag very strict.Slag steel partition method：Converter tapping is to 2/3 molten steel
When, floating plug is accurately added in tapping hole by operative employee, while the nitrogen valve that slag separation is used is opened, and utilizes steel
Slag ratio weight is different, with level pressure nitrogen（Test 0.3-0.5MPa of nitrogen pressure）Steel stream is purged, lighter bits are purged
Go out outside ladle into slag ladle, steel stream is unaffected to be gone successively in ladle, and it is more preferable especially to mix out effect to tapping later stage slag.
Brief description of the drawings
Fig. 1 is slag isolating construction in the utility model embodiment；
Fig. 2 is the nozzle structure of Argon pipe.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As depicted in figs. 1 and 2, a kind of converter tapping slag isolating construction in the present embodiment, including converter 1, the and of ladle 2
Slag ladle 3, ladle 2 are arranged on the lower section of converter 1, and steel stream, the stove skirtboard side of converter are formed between the tapping hole of converter 1 and ladle 2
It is provided with Argon pipe 4, the distance of Argon pipe 4 and tapping hole be 25cm -35cm, and Argon pipe 4 and steel stream are in 50 ° -60 ° angles,
Argon pipe 4 passes through connection by metal hose to outside argon gas source again（It is not drawn into figure）, the steel by Argon pipe 4 to latter stage of tapping
Stream purging, separates slag.
Such as Fig. 2, Argon pipe 4 is that bore grows 10-15cm, 1.5-2.5cm of width, 1-1.5m of length steel pipe.Use
The gas blow pipe of prolate type mouth, steel stream is not influenceed while allowing lightweight slag fully to float.
The utility model is purged to end steel stream, and lighter bits are purged out outside ladle into slag ladle, and steel stream is not
It is impacted to go successively in ladle, it is more preferable that effect especially is mixed out to tapping later stage slag.
In addition to the implementation, the utility model also includes other embodiment, all to use equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within the protection domain of the utility model claims.
Claims (2)
- A kind of 1. converter tapping slag isolating construction, it is characterised in that：Including converter, ladle and slag ladle, ladle is arranged on converter Lower section, steel stream is formed between converter taphole and ladle, the stove skirtboard side of converter is provided with Argon pipe, Argon pipe and tapping The distance of mouth is 25cm -35cm, and Argon Guan Yugang streams are in 50 ° -60 ° angles, and Argon pipe is again by connection by metal hose outside The source of the gas in portion, the steel stream in latter stage of tapping is purged by Argon pipe, separates slag.
- 2. converter tapping slag isolating construction according to claim 1, it is characterised in that：The Argon pipe is bore length 10-15cm, 1.5-2.5cm of width, 1-1.5m of length steel pipe.
