Description
Technical field
The present invention relates to a kind of cantilevered ladle draining sand adding sets, belong to steel-making ancillary equipment technology.
Background technique
In steelmaking process, stuffing sand is added after ladle replacement slide gate nozzle, guarantees mouth of a river automatic casting, reduces
Molten steel and slab quality are not improved to the secondary oxidation of molten steel from oxygen drainage is burnt when opening.The addition manner of stuffing sand has throwing type
With it is funneling.Throwing type addition manner are as follows: people stands on platform, and ladle mouth is tilted towards personnel direction, manually throws to mouth of a river eye
Throw stuffing sand；This method large labor intensity adds sand inaccurate, and refractory consumption is big, and packet mouth hot gas scorches, and operating environment is poor, while added
Stuffing sand it is in irregular shape, influence mouth of a river self-opening rate.Funneling addition manner is to use that sand hopper is added to add stuffing sand after furnace,
But in actual production process, ladle often occurs the phenomenon that bits blocking mouth of a river at position after being hung to furnace, leads to not add
Stuffing sand is forced to change packet, influences normal rhythm of production.
Summary of the invention
The object of the present invention is to provide a kind of cantilevered ladle draining sand adding set, it can be achieved that stuffing sand precisely adds
Add, guarantee that stuffing sand forms Reasonable Shape, improve ladle nozzle self-opening rate, mitigate labor intensity of workers, guarantees normal production section
It plays.

90 ° of overturnings.
A kind of above-mentioned cantilevered ladle addition drainage sand device, described plus sand hopper bottom fixed funnel pipe, filler tube
Axis with plus the axis of sand hopper is overlapped, the length of filler tube needs to guarantee after filler tube is across ladle nozzle, lower end
It can be contacted with the bottom in ladle pocket block hole；The diameter of filler tube is less than ladle nozzle diameter.
A kind of above-mentioned cantilevered ladle addition drainage sand device, the surface area of the overturning platform are greater than steel ladle opening
Area.
The method of stuffing sand is added into ladle nozzle using the present invention are as follows: after ladle replaces slide gate nozzle, in bag tilting machine
On ladle turned into packet mouth upward, ladle is vertical, and starting hoist engine will overturn platform and be down to horizontal position, hinged cantilever to plus hourglass
The position that the axis of bucket is overlapped with the axis in the axis of the axis of ladle nozzle plus sand hole, ladle pocket block hole, pulls downward on
Add sand hopper, due to adding the diameter of filler tube of sand hopper bottom smaller than ladle nozzle diameter, filler tube can protrude into ladle nozzle
Intraocularly whether there is or not bits at the interior detection mouth of a river, if judging the size of ladle nozzle and ladle pocket block hole without bits, from adding sand hopper
Appropriate stuffing sand is added, slowly above mentions and adds sand hopper, it is ensured that stuffing sand forms Reasonable Shape right above the mouth of a river；It unclamps and adds hourglass
Bucket, counterweight will be mentioned above automatically plus sand hopper is parked in a high position, and hinged cantilever makes it avoid overhead traveling crane bull ladle position；Opening hoist engine will turn over
Turn platform and rise to vertical position horizontal by 90 ° of angles, completes addition stuffing sand operation；If there is slag at the mouth of a river, unclamps and add hourglass
Bucket, counterweight will be mentioned above automatically plus sand hopper is parked in a high position；Starting hoist engine rises to platform is overturn horizontal by the perpendicular of 90 ° of angles
Straight position notifies the mouth of a river scarfing cinder of slide plate work, repeats the operation of above-mentioned plus sand.
The invention has the benefit that
The present invention adds sand hole positioning etc. by cantilever-rotating, fixed pulley positioning plus sand hopper, overturning platform, realizes plus sand is precisely right
Position；By adding sand hopper to add stuffing sand, realizes that sand feeding amount accurately controls, save refractory consumption；Stuffing sand Reasonable Shape is controlled, is mentioned
High ladle nozzle self-opening rate, improves molten steel and slab quality；It overturns platform surface product and is greater than steel ladle opening area, guarantee
Steel ladle opening is blocked, prevents personnel from being scorched by hot gas, substantially improves operating environment.The present invention can be used for single mouth of a river and double mouths of a river
Ladle adds stuffing sand.
The present invention is after the three steel mill use of river steel Handan Iron and Steel Co, and ladle nozzle self-opening rate is increased to 99% or more from 93%, effect
Obviously；The stuffing sand addition operation that present invention can be suitably applied to hot repair station, has extensive popularization and application foreground.
