Description
Technical field
the utility model belongs to metallurgical casting industry desulfurizer field, relates in particular to a kind of KR method desulfurizing iron and uses whipping appts.
Background technology
(Kambara Reactor) doctor treatment is a kind of desulfurizing iron method that adopts the mechanical stirring mode.Iron (steel) water when carrying out desulfurization, adds a certain amount of sweetening agent in bag, and requires itself and iron (steel) water thorough mixing, reaction.This just need carry out mechanical stirring to iron (steel) water.Because the good desulfurization dynamics of KR (Kambara Reactor) stirring desulphurization, thereby obtain the extensive concern of domestic and international iron and steel enterprise.
have a kind of mechanical stirring device at present; Its stirring-head is processed by refractory materials; Be shaped as cruciform, promptly around stirring-head, be provided with four agitating vanes, realize stirring iron (steel) water through rotation; But the agitating vane of above-mentioned stirring-head adopts the vertical guide structure mostly, and the said structure design is a lot of to the negative impact of the axial whipping force of stirring-head.
The utility model content
the utility model is intended to overcome the weak point of prior art and provides a kind of simple in structure, long working life, and with low cost, mixing effect ideal KR method desulfurizing iron is used whipping appts.
are for solving the problems of the technologies described above; The utility model is achieved in that KR method desulfurizing iron uses whipping appts, the stir shaft that it comprises flange connector, be fixedly connected with said flange connector and with the affixed agitating vane in stir shaft bottom; Meeting of said agitating vane is untouchable for the convex face; The back iron face of said agitating vane is the convex face.
as a kind of preferred version, the blade bottom width a of the said agitating vane of the utility model is less than vane tip width b.
as another kind of preferred version, the blade of the said agitating vane of the utility model bottom is the convex face with back iron face angle.
further, the said agitating vane of the utility model is three blade constructions.
in addition, the convex face can be selected in the sidewall exterior angle of the said agitating vane of the utility model.
are according to fluid mechanics principle; Agitating vane contour structures form is to stirring the smooth influence of molten iron obviously, and the convex face that the utility model is met untouchable and back iron face through agitating vane designs, and has strengthened the axial whipping force of agitating vane to molten iron; Make stirring region form eddying effect; Thereby improved the stirring precession degree of depth of sweetening agent, promoted the contact reacts of sweetening agent and molten iron, significantly improved the desulfuration efficiency of sweetening agent.In addition; Because the utility model is when in running order; The angular velocity of rotation of the angular velocity of rotation of agitating vane and molten iron eddy region molten iron is often asynchronous; The utility model is designed to the convex face through the blade bottom at agitating vane with back iron face angle, has reduced the circumferential resistance of agitating vane back iron in the face of the molten iron eddy region, thereby has further strengthened the eddying effect of stirring region.Secondly, the utility model also can further be strengthened the eddying effect of stirring region through the convex face design at agitating vane sidewall exterior angle.
Description of drawings
are described further the utility model below in conjunction with accompanying drawing and embodiment.The protection domain of the utility model not only is confined to the statement of following content.
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Among
figure: 1, flange connector; 2, stir shaft; 3, skeleton; 4, agitating vane; 401, meet untouchable; 402, back iron face; 403, blade bottom; 404, vane tip; 405, angle; 406, sidewall exterior angle.
Embodiment
are as shown in the figure, and KR method desulfurizing iron is used whipping appts, the stir shaft 2 that it comprises flange connector 1, be fixedly connected with said flange connector 1 and with the affixed agitating vane 4 in stir shaft 2 bottoms; Said agitating vane 4 meet untouchable 401 for the convex face; The back iron face 402 of said agitating vane 4 is the convex face.In stir shaft 2 refractory material outside protective layers and in the agitating vane 4 refractory materials protective layers, be provided with skeleton 3.
for improving the stress distribution of molten iron stirring region, the blade bottom 403 width a of the said agitating vane 4 of the utility model are less than vane tip 404 width b.
for strengthening the eddying effect of stirring region, the blade bottom 403 of the said agitating vane 4 of the utility model is the convex face with back iron face 402 angles 405 places.
the utility model can be designed to three blade constructions with stating agitating vane 4 when concrete design.
are same, and the convex face can be selected in the sidewall exterior angle 406 of the said agitating vane 4 of the utility model.
The above is merely the preferred embodiment of the utility model
, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
