Abstract
The utility model discloses a molten iron pretreatment desulfuration stirrer, which relates to the technical field of design and manufacturing on the stirrer for a molten iron desulfuration stirring device. The core part of a stirrer body is provided with a cooling water pipe. A stirring shaft is arranged outside the cooling water pipe. The top of the stirring shaft is provided with a coupling flange. The lower part of the stirring shaft is provided with a stirring blade. The bottom of the cooling water pipe is provided with a bottom sealing cover. A refractory material layer is arranged outside the stirrer body. A riveting coupling rib is arranged between the refractory material layer and the stirring blade. The method of application of the stirrer is to couple the coupling flange at the upper part of a stern tube to a rotating shaft of a stirring machine. When in working, the stirrer extends into molten iron, and the stirring machine is started to stir the molten iron. A desulfurizer is added when the molten iron is stirred, the desulfurizer is mixed with the molten iron under stirring and the desulfurizer reacts with sulphur in the molten iron. Generated reactants float on the surface of the molten iron and are removed. The molten iron pretreatment desulfuration stirrer disclosed by the utility model has a simple structure, a reasonable design and extremely ideal desulfuration effect and solves the problems of the traditional desulfuration method.
Description
Technical field
The utility model relates to design and the manufacturing technology field of desulfurizing iron whipping appts with stirring-head.
Background technology
In metallurgical industry blast furnace ironmaking process,, make that the sulphur composition in breeze and the heavy oil enters in the molten iron at present, cause the sulfur content of hot metal height, will refine the high-quality steel to next step like this and bring certain degree of difficulty because powdered iron ore directly contacts coke and heavy oil.Therefore, the desulfurizing iron before steel-making is an important problems.Existing desulfurization is to adopt desulfurization rifle sulfur method.The desulfurization rifle is stretched in the molten iron, spray into sweetening agent and carry out the desulfurization processing.And this sulfur method is very undesirable.Because the sweetening agent light specific gravity, spray into behind the molten iron and float to the surface on very fast, make the bottom molten iron not reach sweetening agent.Thereby influence sweetening effectiveness and molten steel quality.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides the stirring-head that a kind of desulfurizing iron whipping appts is used, and utilizes stirring-head to stir molten iron, makes the sweetening agent wide dispersion in molten iron.Increase sweetening effectiveness.
Structure of the present utility model is as shown in drawings: the core at the stirring-head body has a water-cooled tube.In the outside of water-cooled tube one stir shaft is arranged.At the top of stir shaft one joint flange is arranged.Have one to strengthen coaming plate in the bottom of joint flange.Bottom at stir shaft has agitating vane.One back cover lid is arranged in the bottom of water-cooled tube.Outside at the stirring-head body has refractory masses.Between refractory masses and agitating vane, have rivet clasp and connect muscle.Use of the present utility model is that the joint flange with central siphon top is bound up on the stirrer rotation axis.During work the utility model is stretched in the molten iron, start stirrer molten iron is stirred.Add sweetening agent while stirring, sweetening agent is under agitation sneaked in the molten iron, and the sulphur in sweetening agent and the molten iron reacts.The formation reaction thing floats on the molten iron surface and is eliminated.The utility model is simple in structure, and is reasonable in design.Sweetening effectiveness is very good, has solved the problem that existing sulfur method exists.
