Abstract
The utility model belongs to the field of desulfurization devices in the metallurgy and casting industry, and in particular relates to a molten iron desulfurization mixer. The mixer comprises a flange connecting piece (1), a mixing shaft (2) which is fixedly connected with the flange connecting piece (1), a mixing vane (4) which is fixedly connected with the lower part of the mixing shaft (2), and a flame retardant material layer (5) which is matched with the mixing shaft (2) and the mixing vane (4), wherein the mixing vane (4) consists of four unit vanes which are at a 90-degree angle with one another; the height difference h of one unit vane in the mixing vane (4) and the other three unit vanes is between 40 and 80cm; the vertical longitudinal deflection angle a of the mixing vane (4) is more than 10 degrees and less than 20 degrees; and the vane bottom (6) of the mixing vane (4) is of an arc crown-shaped structure. The mixer is simple in structure, low in cost, long in service life and perfect in desulfurization effect.
Description
Technical field
The utility model belongs to metallurgical casting industry desulfurizer field, relates in particular to a kind of melten iron desulfur agitator.
Background technology
To improving constantly that steel product quality requires, more and more harsh to the requirement of high strength, low-temperature flexibility, cold-formed property and the welding property of steel along with market.For this requirement of satisfying the market, the Iron And Steel Industry of countries in the world all hardy by impurity in reducing steel, particularly reduce the quality that the approach of sulphur content in steel improves steel.
KR(Kambara Reactor) doctor treatment is a kind of molten iron desulfurizing method that adopts the mechanical stirring mode.When iron (steel) water carries out desulfurization in bag, add a certain amount of sweetening agent, and require it fully to mix, react with iron (steel) water.This just need to carry out mechanical stirring to iron (steel) water.Due to KR(Kambara Reactor) desulfurization kinetics characteristic that stirring desulphurization is good, thereby obtain the extensive concern of domestic and international iron and steel enterprise.
A kind of mechanical stirring device is arranged at present; its stirring-head is made by refractory materials; be shaped as cruciform; namely be provided with four agitating vanes in the stirring-head surrounding; realize stirring to iron (steel) water by rotation; but above-mentioned stirring-head sweetening effectiveness is undesirable, and the situations such as torsional deformation often can appear in agitating vane.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and is with low cost, long service life, the melten iron desulfur agitator that sweetening effectiveness is desirable.
For solving the problems of the technologies described above, the utility model is to realize like this.
Melten iron desulfur agitator, the stir shaft that it comprises flange connector, be fixedly connected with described flange connector, with the affixed agitating vane in stir shaft bottom, be assigned in the refractory masses on stir shaft and agitating vane; Described agitating vane is comprised of four unit blades, and is each other 90 o angles; A unit blade in described agitating vane and the difference of altitude h=40 of other three unit blades～80cm.
As a kind of preferred version, the vertical drift angle 10o≤a of the facade of agitating vane described in the utility model≤20 o.
As another kind of preferred version, the curved crown structure in the blade of agitating vane described in the utility model bottom.
The utility model is simple in structure, and is with low cost, long service life, and sweetening effectiveness is desirable.The unitized design of the curved crown structure in bottom of the vertical drift angle 10o≤a of facade of the difference of altitude h=40 of the utility model by a unit blade in agitating vane and other three unit blades～80cm, agitating vane≤20 o and agitating vane, significantly extended the work-ing life of whipping appts, novel vane structure has improved the mixing effect of molten iron in addition, has obviously strengthened desulfuration efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Protection domain of the present utility model not only is confined to the statement of following content.
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In figure: 1, flange connector; 2, stir shaft; 4, agitating vane; 5, refractory masses; 6, blade bottom.
Embodiment
As shown in the figure, melten iron desulfur agitator, the stir shaft 2 that it comprises flange connector 1, be fixedly connected with described flange connector 1, with the affixed agitating vane 4 in stir shaft (2) bottom, be assigned in the refractory masses 5 on stir shaft 2 and agitating vane 4; Described agitating vane 4 is comprised of four unit blades, and is each other 90 o angles; A unit blade in described agitating vane 4 and the difference of altitude h=40 of other three unit blades～80cm, wherein, the h preferred value is 55cm.
The vertical drift angle 10o≤a of the facade of agitating vane 4 described in the utility model≤20 o, a is preferably 13 o.The generation of agitating vane facade dross phenomenon can also be avoided in the vertical drift angle of facade.
For improving the stress distribution of agitating vane bottom, the blade bottom 6 curved crown structures of agitating vane 4 described in the utility model.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
