Description
Technical field
The invention belongs to field of metallurgical equipment, relate in particular to a kind of rotary spray gun for use in molten iron desulfurization.
Background technology
For satisfying market to the needs that the more and more high requirement of steel product quality and Iron and Steel Production producer self reduce cost, seek rational technical process and effectively the smelting means be the important subject of metallurgy industry always.It is the optimised process that blast furnace-converter-continuous casting process flow process reduces sulphur content in the steel that molten iron pretreatment desulfurizing is generally acknowledged.At present, from the desulfurizing iron state of art, can be divided into paddling process and blowing process.Shortcomings such as the independent use of above-mentioned means all can not be satisfied the requirement of desulfurizing iron technology aspect low cost, high-level efficiency to a certain extent, and its reason is to exist iron loss big when adopting stirring desulphurization, and hot metal temperature drop is big; When adopting the magnesium granules winding-up, because existing blowing device is fixed design, there are problems such as utilization ratio is low in the sulphur in its particle magnesium and the molten iron in reaction fashion.
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 easy to operate, sweetening effectiveness is good, long service life, and sorbent utilization is high and do not have a rotary spray gun for use in molten iron desulfurization of the long-pending phenomenon of sulphur slag muck.
For achieving the above object, the present invention is achieved in that
A kind of rotary spray gun for use in molten iron desulfurization, it comprises: flange connector, the outer tube that is 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 the right-angled trapezium body; The top refractory materials layer plane of described agitating vane and the 0 °＜β in drift angle of horizontal plane≤45 °.
As a kind of preferred version, the present invention can be furnished with interior pipe in described outer tube.
As another kind of preferred version, the cross section of agitating vane of the present invention is " ten " word structure; The positive face thickness a of described agitating vane refractory masses is greater than the back side thickness b of agitating vane refractory masses.
In addition, the positive length c of agitating vane refractory masses of the present invention is greater than the back side length d of agitating vane.
Fixedly is furnished with stiffening web between agitating vane of the present invention.
The thickness of outer tube of the present invention bottom refractory masses is greater than the thickness of outer tube top refractory masses.
The present invention integrates paddling process and blowing process, and it utilizes stirring action to significantly improve the reaction efficiency of sulphur in magnesium granules and the iron liquid when carrying out the magnesium granules desulfurization.The present invention is simple in structure, and is easy to operate, and sweetening effectiveness is good, prolonged the work-ing life of spray gun greater than the structure design of the back side thickness b of agitating vane refractory masses by the positive face thickness a of agitating vane refractory masses.The structure design of top refractory materials layer plane by agitating vane and the 0 °＜β in horizontal plane drift angle≤45 ° has solved the long-pending phenomenon of sulphur slag muck.
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 an one-piece construction synoptic diagram of the present invention;
Fig. 2 for A-A among Fig. 1 of the present invention to sectional view;
Fig. 3 is a kind of embodiment structural representation of agitating vane of the present invention;
Embodiment
