Description
Technical field
The utility model is related to a kind of turbulent flow suppressor.More particularly to it is a kind of for buffering tundish long nozzle beam molten steel
Continuous casting production crescent block turbulent flow suppressor.
Background technology
Continuous casting production can increase substantially the quality of continuous casting billet as the important reactor of cleaning molten steel.In recent years
Carry out people and employ tundish turbulent flow suppressor mostly, during molten steel injection tundish, tundish turbulent flow suppressor energy
The tubulence energy of molten steel in tundish is reduced, stable molten steel improves the flow behavior of molten steel, postpones the residence time, promotes field trash
Float, and splash when molten steel starts cast can be prevented and cause secondary oxidation.
Traditional turbulent flow suppressor only produces cushioning effect to long nozzle beam molten steel, does not have eddy flow effect.Built-in sheet
Although block turbulent flow suppressor can produce eddy flow, eddy flow effect is small, and block easily washes away and corroded.
The applicant has a kind of turbulence controller for continuous casting middle ladle of patent (CN104057044), including controller body and
Formed in the intrinsic hollow chamber of controller, the hollow chamber upper end is provided with provided with outlet, bottom centre of hollow chamber
Rotation direction is consistent, not the cube catch vertical with side, makes the speed of molten steel one rotation of formation injected through tundish long nozzle
Field is spent, liquid fluctuating can be prevented excessive, stable molten steel reduces tubulence energy, and the centrifugal force of generation is significantly promoted again
The collision probability of non-metallic inclusion, Collision coagulation preferably floats after growing up.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned present situation, it is desirable to provide a kind of simple in construction, to molten steel purifying effect more
Good continuous casting production crescent block turbulent flow suppressor.
The implementation of the utility model purpose is, continuous casting production crescent block turbulent flow suppressor, suppressor body
Nei You hollow chamber, the hollow chamber upper end is provided with outlet；Crescent moon of the suppressor body bottom portion center provided with 4 annular arrays
Shape solid block, crescent solid dog height is the 1/3~4/5 of hollow chamber's height, and cross section outer is by 4 sections of circular arc groups
Into.
The utility model passes through the three-dimensional block of the crescent that an annular array is provided with bottom centre of hollow chamber, long nozzle
The stagnation pressure that beam is produced is maximum in underface bottom, forms a higher-pressure region, the height of crescent solid block is that higher-pressure region is high
3~5 times of degree, the passage constituted using crescent block in higher-pressure region forms strong eddy flow.
The utility model uses the three-dimensional block of the crescent of annular array, and the passage that crescent solid block is constituted meets stream
Mechanics feature, substantially, rotary speed is conducive to field trash to assemble to center to the eddy flow effect of generation up to 40r/min；This rapids
Molten steel beam can be converted into eddy flow by stream suppressor, significantly consume tubulence energy by eddy flow, liquid fluctuating is smaller.
The utility model is more preferable to the cushioning effect of long nozzle beam molten steel and the clean-up effect of molten steel.
