Description
Technical field
The invention belongs to field of steel-making, and in particular to a kind of bottom water outlet of ladle, ventilating structure.
Background technology
Current smelter reduces non-metallic inclusion content, and adjust steel to further increase the degree of purity of molten steel
Coolant-temperature gage is to improve the quality of steel, to refine special steel material, such as the wheel hub steel etc. of bullet train.Meet market need
It asks, is just wideling popularize BOTTOM ARGON BLOWING furnace outer refining technology.So-called BOTTOM ARGON BLOWING furnace outer refining technology, being will be in converter or electric furnace
The molten steel for completing just to refine is transferred in ladle, by that will have the argon gas of certain pressure and flow, is constantly blown by ladle bottom
Enter in ladle and molten steel is refined again.In external refining, play the role of " stirring " to molten steel by applying argon gas, it can be uniform
The ingredient and temperature of molten steel, the casting performance for improving molten steel, the content and pernicious gas for reducing non-metallic inclusion, to reach
Improve steel quality and refines the purpose of special steel material.Existing ladle bottom is generally provided molten steel hole and dedicated for supplying gas
To the injection well that molten steel is stirred, tapping water hole is also required to supply gas to prevent molten steel solidification in molten steel before not going out molten steel
It is unfavorable for tapping on hole.But supplying gas on molten steel hole is generally adopted by the plug in six holes and sending on the injection well specially supplied gas
Structure difference of supplying gas on gas brick, causes entire ladle interior air-flow and bubbles volume difference that stirring unevenness is caused dead angle occur, influences
The degree of purity and quality of finished steel.And the tapping water-bound of existing ladle bottom is complicated, slide plate slides less effective, it is entire sliding
The outer framework of plate is fragile, troublesome maintenance.And existing technology all controls out molten steel, but slide plate using one slide-plate sliding
Slide plate i.e. mobile just wants inswept molten steel during sliding, be easy to cause adhesion, and the structure for entirely going out molten steel is possible in molten steel
The place touched is either fixed to be also moveable all fragile, needs more block, it is convenient that mobile sliding block is replaced, but solid
Determine structure and replace cumbersome, sliding block can polish again, but the structure scutching being fixed on ladle is inconvenient.

Row interlocking or the simple prior art principle being spirally connected.It is ventilative on the corresponding porous plug of apopore and air brick in extractive process
It fills in and supplies gas in a ladle in the same direction, molten steel in ladle is stirred, since the gas pushing quantity of both sides is identical, the removal effect of field trash
Identical, the molten steel refining effect in entire ladle is the same, improves the quality of tapping.Need air brick side when molten steel to stop
It supplies gas, hangs in sliding component and lifted entire shadoof by putting forward plate hole locations, the drop hanger on shadoof drives sunpender to pull up, and hangs
Bar promotes slide lid and is promoted, to walk the porous plug on quasi- slide plate one upwards so that porous plug and the plate hole two on slide plate two
It is no longer corresponding with apopore, and plate hole one on slide plate two plate hole two and apopore it is corresponding, to carry out out molten steel.Slide lid
Outer corresponding plate hole one is equipped with out steel conduit 6, and 3-5 times that the bore for going out steel conduit is two bore of the plate hole, makes molten steel in plate
It is smoothly flowed out between Kong Eryu tapping catheter positions, the bigbore molten steel that switches out is smooth, and molten steel is not easy to plug, and improves tapping
Efficiency.
It is that the bottom of ladle sets the structure of two outlets in the present embodiment, tries according to the structural principle of ladle and for many years
The effect tested, the mixing effect of two air outlet structures are better than the stirring of existing 1 or 3 or 4 or more outlet position
Impurity-eliminating effect.
Embodiment two：
Porous plug is filled on the bore being in the dress porous plug on the air brick and the slide plate one unlike the embodiments above
Caliber size is consistent.I.e. two porous plug sizes are the same, and gas pushing quantity and speed of supplying gas are same when use.
Embodiment three：
It is unlike the embodiments above be in the dress porous plug on the air brick bore be the slide plate one on fill porous plug
The size of 3-4 times of bore, i.e., two porous plugs is also different, and the speed of supplying gas adjusted when using on two porous plugs makes two
The gas output of same time is equal on porous plug, to ensure the removal uniformity of field trash.
