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 operation, steel-making after add
Furnace outer refining process could be produced.Molten iron pre-desulfurization has turned into one of indispensable operation 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 the 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 by NKK and Sumitomo Metal Industries etc. later.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 during desulfurization just floated to slag, and some desulfurization products float insufficient still in molten iron, do not have the effect of desulfurization
Really, mixing power is weak, causes desulphurization reaction speed slow, and desulfuration efficiency is low.
The content of the invention
It is contemplated that overcoming the deficiencies in the prior art part and providing a kind of simple structure, mixing power is strong, desulfuration efficiency
KR high dusts melt desulfurization agitator.
In order to solve the above technical problems, what the present invention was realized in.
Melt desulfurization turbine type agitating device, including stirring body of the bottom equipped with 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
The signal transmission port for belonging to 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 of the present invention is 33~
66 degree.
Further, the present invention can be provided with poke hole on the stirring vane.
The present invention is by jet pipe to being blown into nitrogen in molten iron（Or other inert gases）, mixing power is improved, can also reduce and stir
