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 of efficiency high dusts melt desulfurization agitator.
In order to solve the above technical problems, what the utility model was realized in.
Melt desulfurization turbine type agitating device, including bottom are furnished with the stirring body of stirring vane；In the stirring vane
Level is fixed with first wheel and the second wheel hub successively for both sides up and down；Jet pipe is fixed with the middle part of agitating shaft；Institute
State first wheel inner chamber and be laterally fixed with branch pipe；The Single port of the branch pipe is communicated with the lower port of jet pipe；Branch pipe
Another port communicated with the spout of first wheel；Metallic conduction slip ring is fixed with the top of the agitating shaft；The gold
One signal transmission port of category conducting slip ring connects with jet pipe；Another signal transmission port and power supply of the metallic conduction slip ring
The signal transmission port of interface connects；Refractory material protective layer is fixed with the stirring body exterior.
As a kind of preferred scheme, the angle between the surface and first wheel surface of stirring vane described in the utility model
For 33~66 degree.
Further, the utility model can be provided with poke hole on the stirring vane.
The utility model is blown into nitrogen into molten iron by jet pipe（Or other inert gases）, mixing power is improved, can also be dropped
The temperature of low agitating device, extends its service life, Sulfur Content in Hot Iron weight content is reduced to target call, realizes molten iron magnesium
Desulfurization is efficient, meets clean steel production needs.The utility model blade straight by being provided with, and surface and the circle of blade
Angle between the upper surface of shape disk body is 30~60 degree, and the blade being obliquely installed can effectively improve stirring efficiency.
