Developed rapidly as modern industry is produced with scientific and technical, the requirement to steel product quality is increasingly improved.For example, being
Steel billet is avoided to produce underbead crack and obtain good surface quality, it is desirable to which the sulfur content of ordinary steel is less than 0.020%；In order to
Make structural steel that there is uniform mechanical performance, it is desirable to which sulfur content is less than 0.010% in steel；In order that oil and natural gas delivery pipe,
Petroleum refining unit steel, offshore production platform steel, cryogenic steel, medium-thickness ship plate steel and aviation steel etc. have anti-hydrogen induced cracking
The impact flexibility of performance, mechanical performance evenly and Geng Gao, silicon steel has good electromagnetic performance, and sheet steel has excellent
Deep drawability etc., it is desirable to which sulfur content is less than 0.005% in steel.It is required that the steel of such low-sulfur, with traditional blast furnace continuous casting steel machine
Smelt iron a converter steelmaking process be difficult production, only before steel-making plus molten iron pre-desulfurization process, steel-making after add
Furnace outer refining process could be produced.Molten iron pre-desulfurization has turned into one of indispensable process of optimization metallurgical production process, it
Continuous casting steel machine can be reduced | the coke ratio and raising productivity ratio of ironmaking, reduce lime consumption amount and quantity of slag of steel-making etc., so as to reduce
Production cost.
Mainly there are KR methods, RS methods and DO methods in mechanical mixing method desulfurization.KR methods were wide cigarette iron institutes of Nippon Steel in 1963
Start to develop, and industrial production is put into nineteen sixty-five.Used later by NKK and Sumitomo Metal Industries etc..Above-mentioned KR methods profit
Molten iron is set to be contacted well with desulfurizing agent with mechanical agitation, desulfuration efficiency is high and stablizes, and can obtain low-sulfur or super-low sulfur iron
Water.But, existing KR methods mechanical stirring device, generally existing stirring force direction is single, and mixing power is not enough, can cause some desulfurization
Agent, does not participate in desulfurization and has just floated in slag, the insufficient effect that desulfurization is not had still in molten iron of some desulfurization products floating
Really, mixing power is weak, causes desulphurization reaction speed slow, desulfuration efficiency is low.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provide a kind of simple in construction, and mixing power is strong, desulfurization
The KR agitators of efficiency high.
In order to solve the above technical problems, what the utility model was realized in.
A kind of KR agitators, including bottom are furnished with the stirring body of stirring vane；Characterized in that, the stirring body bag
Include air storage chamber and gas distribution bin；Gas injection pipe is provided with the gas distribution bin；The upper port of the Gas injection pipe with
Air storage chamber is communicated, and its lower port is communicated with gas distribution bin；Several Gas injections mouthful are provided with the side wall of the gas distribution bin；
Sleeve pipe I is longitudinally provided with the center of the stirring body；Main core pipe is provided with described sleeve pipe I；In the stirring vane
Interior central area is provided with distributor；Branch pipe is transversely provided with the stirring vane；The port of the main core pipe and branch pipe
Communicated respectively with the port of distributor；Metallic conduction slip ring is fixed with the top of described sleeve pipe I；The metallic conduction slip ring
A signal transmission port connect with main core pipe；Another signal transmission port of the metallic conduction slip ring and power supply wiring port
The signal transmission port of component connects；Refractory material protective layer is fixed with the stirring body exterior.
As a kind of preferred scheme, the utility model is fixed with sleeve pipe II in the nozzle portion of the branch pipe.
The utility model is passed through the gas in gas distribution bin by the Gas injection pipe being provided with gas distribution bin, by
Runner is blown into nitrogen into molten iron by the Gas injection pipe of gas distribution bin（Or other inert gases）, mixing power is improved, also
The temperature of agitating device can be reduced, extends its service life, Sulfur Content in Hot Iron weight content is reduced to target call, realizes iron
Water-magnesium desulfurization is efficient, meets clean steel production needs.In addition, the utility model can pass through main core pipe and branch pipe by carrier gas
The blowing desulfurization agent into molten iron, desulfurized effect is further strengthened.
The utility model imports electric current, due to accelerating leading for electronics by slipping into molten iron depths in its exit site
Enter or export speed, so as to enhance effect of the potential energy to the chemical component of desulphurization reaction.Bubbles of carrier gas is in desulfurizing agent feed zone
Effectively stirring, exchanges refining process from dispersity while strengthening fluid kinetic exchange process and is converted into active state
Exchange, this helps to whole molten iron space in bag to be attracted to sweetening process, has finally been to speed up desulfuration operations, has protected
The utilization rate for reducing temperature loss and improving desulfurizing agent is demonstrate,proved.
