Description
Technical field
The utility model belongs to technical field of ferrous metallurgy more particularly to a kind of Con casting ladle molding casting long nozzle.
Background technique
In continuous casting production process, molten steel is flowed into during tundish by ladle can generate secondary oxidation phenomenon, in order to mention
High slab quality reduces the secondary oxidation of molten steel, and long nozzle is equipped between collector nozzle of ladle and tundish, is obstructed by long nozzle
Molten steel is directly contacted with air, to reduce the increase of steel water oxygen and nitrogen content.Long nozzle and collector nozzle of ladle auxiliary section
The key for being sealed to isolation molten steel and contacting with air of position does not have the work of isolation air not only if sealing effect is bad
With the Involving velocity for the stream that can tap instead because of high velocity stream makes more air and molten steel interact, aggravates the secondary oxygen of molten steel
Change.The sealing of existing long nozzle matching part uses refractory fibre washer, and the upper end cavity shape of long nozzle is the rim of a bowl shape, and
In matching part blowing argon.This sealing structure has the following deficiencies: first is that refractory fibre washer has certain gas permeability, no
The volume of air can be prevent completely to inhale；Second is that even if between collector nozzle of ladle and long nozzle Argon, it is also difficult to form positive pressure, argon gas
It still can enter molten steel after the air mixing inhaled with volume.
Utility model content
The purpose of this utility model is that in view of the above shortcomings of the prior art, providing a kind of Con casting ladle molding casting use
Long nozzle.
To solve the above problems, technical solution adopted in the utility model is:
A kind of Con casting ladle molding casting long nozzle, including long nozzle ontology, the long nozzle ontology includes cylindrical portion
With the rim of a bowl portion for being located at the cylindrical portion upper end, cylinder chamber is offered inside the cylindrical portion, is offered inside the rim of a bowl portion
The rim of a bowl chamber being connected to the cylinder chamber, the upper surface in the rim of a bowl portion are equipped with block ring, and block ring upper surface is equipped with the
One gasket, the cavity wall of the rim of a bowl chamber is equipped with the second gasket, offers first annular chamber inside the block ring, described
Several first row stomatas being connected to the first annular chamber are offered on the inside of block ring, the block ring outside offers and institute
The first air inlet of first annular chamber connection is stated, the first air inlet other end is connected to Argon conduit, the Argon conduit
It is connected with argon gas transportation system, the upper surface in the rim of a bowl portion offers the second air inlet, and second air inlet is located at institute
It states on the inside of block ring, the second annular chamber is offered inside the cylindrical portion, offered on the inside of the cylindrical portion several with described the
The second row stomata of second ring chamber connection, second air inlet are connected to the second annular chamber by air slot.
Further technical solution is described peripherally disposed at least four of first row stomata.
Further technical solution is described peripherally disposed at least four of second air inlet.
Further technical solution is that block ring upper surface is equipped with accommodation groove, and first gasket is set to
In the accommodation groove.
The beneficial effects of adopting the technical scheme are that block ring, the first gasket and ladle lower surface are matched
It closes and forms first of sealing；Collector nozzle of ladle, long nozzle ontology and the second gasket cooperatively form second sealing, and first close
The argon gas-sealed ring that micro-positive pressure is formed between envelope and second sealing, can effectively prevent the entrance of air, greatly reduce air
Volume inhale chance, improve hermetic barrier effect.In addition, first sealing second sealing between argon gas by second into
Stomata enters the second annular chamber, avoids and directly spills into waste caused by atmosphere, saved cost, into the second annular chamber
Argon gas is blown into molten steel by second row stomata forms a large amount of minute bubbles, while the shearing force that molten steel generates smashes minute bubbles
At more tiny bubble, enter tundish and fast in more tiny bubble and the minute bubbles not smashed capture molten steel after inclusion particle
Speed floats, and is adsorbed by tundish covering flux, improves the cleannes of slab.
