Abstract
The invention belongs to the field of a desulphurization device in a metallurgy casting industry, and particularly relates to a four-blade molten iron desulphurization stirring device. The four-blade molten iron desulphurization stirring device comprises a flange connection piece (1), a stirring shaft (2) fixedly connected with the flange connection piece (1), stirring blades (4) fixedly connected with the lower part of the stirring shaft (2), and fireproof material layers (5) matched on the stirring shaft (2) and the stirring blades (4); the four stirring blades (4) mutually form inclined angles being 90 degrees; conical protection bases (6) are fixedly arranged between the stirring blades (4); and vertical drift angles a of vertical faces of the stirring blades (4) are more than or equal to 10 degrees and is less than or equal to 15 degrees. The four-blade molten iron desulphurization stirring device provided by the invention has the advantages of simple structure, low cost and long service life; the conical protection bases (6) are fixedly arranged between the stirring blades (4), so that the melt spattering phenomenon can be effectively prevented from occurring; and a stirring head can bear high stirring torque in a working process.
Description
Technical field
The invention belongs to metallurgical casting industry desulfurizer field, relate in particular to a kind of quaterfoil molten iron desulphurization stirring device.
Background technology
Along with market 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.For this requirement of satisfying the market, the Iron And Steel Industry of countries in the world all hardy by reducing impurity in the steel, particularly reduce the quality that the approach of sulphur content in the 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.Because 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 around stirring-head, be provided with four agitating vanes; by the stirring of rotation realization to iron (steel) water; but above-mentioned stirring-head the situations such as deformable blade often can occur because bearing huge stirring moment of torsion when work, be greatly affected the work-ing life of stirring-head.In addition, existing quaterfoil stirring-head some melt splash phenomenons also can occur because of the defective on the structure design.
Summary of the invention
The present invention 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 quaterfoil molten iron desulphurization stirring device that can avoid melt splash phenomenon to occur.
For solving the problems of the technologies described above, the present invention realizes like this.
Quaterfoil molten iron desulphurization stirring device, 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 the agitating vane; Described agitating vane is four, and is each other the 90o angle; Between described agitating vane, be fixed with the taper protecting seat.
As a kind of preferred version, vertical drift angle 10 o of agitating vane facade of the present invention≤a≤15o.
The present invention is simple in structure, and is with low cost, and long service life by be fixed with taper protecting seat structure between agitating vane, can effectively avoid melt splash phenomenon to occur, and stirring-head can bear huge stirring moment of torsion when work.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.Protection scope of the present invention not only is confined to the statement of following content.
Fig. 1 is one-piece construction schematic diagram of the present invention.
Fig. 2 is the vertical view of Fig. 1 of the present invention.
Among the figure: 1, flange connector; 2, stir shaft; 4, agitating vane; 5, refractory masses; 6, taper protecting seat.
Embodiment
As shown in Figures 1 and 2, quaterfoil molten iron desulphurization stirring device, 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 bottoms, be assigned in the refractory masses 5 on stir shaft 2 and the agitating vane 4; Described agitating vane 4 is four, and is each other the 90o angle; Between described agitating vane 4, be fixed with taper protecting seat 6.
Vertical drift angle 10 o of agitating vane 4 facades of the present invention≤a≤15o, a is preferably 13 o.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
