Abstract
A blow turbulence preventing controller of CC ladle of steelmaking is to provide air bricks connected to a gas cell in common turbulence preventing controller, and the cell is connected to the argon pipe connected to the CC ladle with a metal pipe, the dam is provided on the ladle base between the retaining wall and the sliding gate in use, which plays roles of reducing turbulence flow energy of molten steel by turbulence preventing the controller and removing impurities by stirring molten steel with argon simultaneously, which applies to CC ladle to remove impurities and improve merit rating by blowing argon to stir molten steel.
Description
Affiliated technical field
The utility model relates to the anti-turbulence inhibitor of a kind of improved steel-making continuous casting tundish, needing to be suitable for blowing argon gas to stir molten steel to reduce the tundish of molten steel inclusion content, raising molten steel cleanliness factor.
Background technology
When molten steel enters tundish from ladle, form bigger liquid-liquid jet, the molten steel Turbulent Kinetic is big, often cause molten steel disturbance, slag to entrainment, cause the molten steel secondary pollution, simultaneously beam district tundish refractory material is had bigger erosion damage effect, adding anti-turbulence inhibitor is one of approach that effectively improves the Turbulent Kinetic dissipative shock wave.Abroad about the research of the anti-turbulence inhibitor of tundish with use relatively early, domestic in this respect work has in the last few years also had very great development, has obtained certain practical application effect.
In the tundish molten steel, be blown into argon gas, the buoyancy of Argon Bubble produces the airlift pump phenomenon, not only can catch inclusion particle, and carries the inclusion particle removal of together floating, and help field trash collision and grow up and get rid of, can play the metallurgy action of purify hot metal.Chinese scholars has been done the theory and the laboratory research of much stirring molten steel about the tundish blowing argon gas, some practical applications have been obtained abroad, and more just rest at home in the laboratory work, the practical application of tundish blowing argon gas purify hot metal rarely has report.
The enforcement approach of external tundish blowing argon gas purify hot metal normally is embedded in the air blowing brick in the permanent layer at the bottom of the tundish bag, as Japan toward friendly metal deer island steel mill and wide field steel mill of Nippon Steel; Also have report to adopt rotary spray gun to be blown into argon gas in the tundish, its basic principle is that an electric rotating machine is installed near tundish, by swivel joint lance is inserted in the tundish molten steel, and one side rotary spray gun then is Yi Bian be blown into argon gas.Two kinds of methods have all played the effect of field trash in the good removal molten steel, but first method working strength of workers when the remaining air blowing brick of cleaning is bigger, and the turnaround time of tundish is also long, and the second method equipment investment is bigger, and needing external power, energy consumption is than higher.
Summary of the invention
The present invention installs blowning installation in the anti-turbulence inhibitor of tundish, the function that will anti-turbulence inhibitor and the effect of tundish blowing argon gas unite two into one, and provide that a kind of purify hot metal efficient height, installing/dismounting are easy, the device of the tundish blowing purification molten steel of small investment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the generalized section of a kind of structure of the present invention.
Fig. 2 is assembling and the fundamental diagram of the present invention in tundish.
1 air brick among the figure, 2 anti-turbulence inhibitors, 3 metallic conduits, 4 air chambers, 5 long nozzles, 6 external argon gas pipelines, 7 molten steel.
The specific embodiment
With reference to Fig. 1, air brick 1 is installed in the anti-turbulence inhibitor 2, and air brick 1 links to each other with air chamber 4, and air chamber 4 can design in air brick 1 inside, also can reserve between air brick 1 and anti-turbulence inhibitor 2, air chamber 4 is connected with external argon gas pipeline by metallic conduit 3.Air brick 1 adopts corundum matter, corundum spinel, chrome corundum, Zirconium corundum or high alumina refractories to adopt cast or machine to press the mode moulding, after burning till through 110 ℃～1600 ℃ dryings, metallic conduit 3 is installed, adopt the mode of cast that air brick 1 is installed in the anti-turbulence inhibitor 2 then, less than making the anti-turbulence inhibitor of air blowing type after 1400 ℃ of dryings.
With reference to Fig. 2, on the present invention was installed at the bottom of the tundish bag below the continuous casting tundish long nozzle 5, metallic conduit 3 was connected with external argon gas pipeline 6.After molten steel 7 enters tundish from long nozzle 5, run into the constraint of anti-turbulence inhibitor, the molten steel diffusion motion that makes progress stirs, mixes with argon gas in being blown into tundish, argon gas is owing to be subjected to buoyancy function rising discharge, and field trash collides mutually, grows up, gets rid of in the drive molten steel.Finish using, the anti-turbulence inhibitor of remaining air blowing type disintegrates automatically with surplus, the residual lining of casting, disassembles conveniently.
With domestic certain sheet blank continuous casting tundish is object, by the mathematical physics simulation means, is reference frame with common anti-turbulence inhibitor, and after use the present invention blew and stirs, the clearance of field trash total amount can improve 8%～10% in the molten steel.
