Description
Technical field
The utility model relates to a kind of device improving slag-stopping awl of converter pushing off the slag success ratio, belongs to steel-making slag pushing equipment technical field.
Background technology
A large amount of slag containing harmful element can be produced in convertor steelmaking process, steel-making terminates rear slag and can swim on molten steel, in converter tapping process, especially after most of molten steel is discharged, stronger eddy current can be formed above tap hole, slag is involved in molten steel, and then considerable influence is produced to quality of molten steel.In order to prevent being involved in molten steel by slag in tapping process, people have invented the various slag stopping methods such as slag-blocking ball pushing off the slag, slag stop cone pushing off the slag, pneumatic dreg blocking, electromagnetism pushing off the slag, slide plate pushing off the slag.In numerous slag stopping method, slag stop cone pushing off the slag method is adopted by most of steelworks owing to having the feature such as simple to operate, cost is low, pushing off the slag is effective.At present, slag stop cone slag-blocking apparatus mainly comprises slag stop cone, slag stopping, slag stopping lever arm and slag stopping track, and slag stop cone is arranged on slag stopping lever arm front end, and slag stopping lever arm rear end is installed on slag stopping, and slag stopping can along slag stopping rail moving; In order to execute-in-place is convenient, slag stopping track is marked with slag stopping and throws in position, to meta, waits for position and slag stopping lever arm lower limit, slag stopping lever arm lower limit refer to slag stopping lever arm throw in slag stop cone time place position, generally from the horizontal by 15 ~ 30 degree of angles.When slag stopping moves to input position, slag stopping lever arm is dropped to lower limit and complete pushing off the slag operation.The subject matter that existing slag stop cone pushing off the slag method exists is that slag stop cone occurs bending and deformation or in slag stopping installation process, sideslip occurs in carrying journey, cause slag stop cone can accurately not fall in tap hole in launch process, cause slag to flow into ladle, thus reduce slag stop cone pushing off the slag success ratio.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device improving slag stop cone pushing off the slag success ratio.This device is by arranging the pre-aligning gear of slag stop cone, and slag stop cone first carries out pre-centering before input, can adjust in time when finding that slag stop cone misaligns, and is improve the success ratio of slag stop cone input, solve a background technology difficult problem by pre-centering.
The technical scheme solved the problems of the technologies described above is:
Improve a device for slag stop cone pushing off the slag success ratio, comprise slag stop cone, slag stopping, slag stopping lever arm and slag stopping track, its improvements are: also comprise the pre-aligning gear of slag stop cone be installed on slag stopping track in formation.
Above-mentioned a kind of device improving slag stop cone pushing off the slag success ratio, opens round-meshed metal sheet centered by the pre-aligning gear of described slag stop cone, is installed on the slag stopping track outside converter body.
Above-mentioned a kind of device improving slag stop cone pushing off the slag success ratio, described slag stop cone pre-aligning gear center hole diameter is identical with tap hole diameter.
Utilize the utility model to carry out pushing off the slag operating process to be:
After having changed new tap hole, first carry out tap hole and slag stop cone centering is demarcated.A new slag stop cone is arranged on slag stopping lever arm front end, by converter inclining to tapping angle, start slag stopping to input position, slag stopping lever arm drops to lower limit, adjustment converter inclining angle, make slag stop cone conehead and tap hole center centering, record converter inclining angle, then slag stopping lever arm is lifted, retreat slag stopping to meta, pushing off the slag lever arm is dropped to lower limit, the pre-aligning gear of mobile slag stopping, make its center hole and slag stop cone conehead centering, after centering, pre-for slag stopping aligning gear is fixed on slag stopping track, and lift slag stopping lever arm, by slag stopping back to wait position, centering has been demarcated.
Before converter tapping, slag stop cone is arranged on slag stopping lever arm front end, start slag stopping to meta, slag stopping lever arm is dropped to lower limit, adjustment slag stop cone, make slag stop cone conehead and slag stopping pre-aligning gear center hole centering, after centering completes, lift slag stopping lever arm, after waiting converter inclining to the angle of demarcating during pre-centering, slag stopping is started and throws in position, slag stopping lever arm drops to lower limit, throws in slag stop cone and completes pushing off the slag operation, then lift slag stopping lever arm, slag stopping is retreated and waits for position, wait for that next time throws in.When after the tap hole more renewed, tap hole position changes, and needs again centering to demarcate.
The beneficial effects of the utility model:
The utility model can carry out pre-centering operation to slag stop cone by arranging pre-aligning gear outside stove, does not affect the tapping time, improves production efficiency, improve slag stop cone pushing off the slag success ratio; The quantity of slag under ton steel can control within 5kg by this device, decreases molten steel and pollutes, improves quality of molten steel; The advantages such as the utility model has simple, convenient, with low cost, are suitable for promoting the use of in iron and steel enterprise.
