Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization, in particular to a desulfurization agitator device. Background Art

[0002] Desulfurization technology in molten iron pretreatment has developed rapidly. There are more than a dozen treatment methods at home and abroad. The most widely used and representative ones are mechanical stirring method and injection method. Since the operating cost of mechanical stirring method is lower than that of injection method and the desulfurization efficiency is relatively high, major domestic steel mills are increasingly using mechanical stirring method. The agitator is an important part of the mechanical stirring method, and its performance directly affects the desulfurization efficiency of the agitator. The agitator is inserted into the molten iron and rotates under the drive of the motor, so that the desulfurizer can fully react chemically in the molten iron. In the prior art, the agitator mainly adopts a coaxial design. The disadvantage of this agitator is that during the stirring process of the agitator, the kinetic energy of the molten iron flow field near the tank wall is very small, and the molten iron and the desulfurizer cannot fully react at this location, thereby affecting the desulfurization efficiency.

[0003] According to a publicly disclosed desulfurization agitator device (publication number: CN 107674935 A), it includes a crankshaft steel core skeleton, a flange arranged at the top of the crankshaft steel core skeleton, an agitator arranged at the bottom end of the crankshaft steel core skeleton, and a V-shaped anchor arranged inside the device; a refractory casting layer is arranged at the bottom of the crankshaft steel core skeleton; four blades of the agitator are evenly distributed at the bottom of the crankshaft steel core skeleton along the circumference of the bottom of the crankshaft steel core skeleton; a refractory casting layer is arranged on the surface of the agitator; the refractory material layer uses fused mullite as the main raw material, and is supplemented with coke sapphire, kyanite and cement composite binder. The advantages of this invention are: the desulfurization agitator adopts a crankshaft steel core skeleton design, which can meet the process requirements of stirring desulfurization, increase the dynamic field of molten iron during stirring, improve stirring uniformity, and has the characteristics of simple structure, high desulfurization efficiency and long life. The above application cooperates with components such as the crankshaft steel core skeleton and the agitator, and it is difficult to clean the impurities on the inner wall of the main box, which causes impurities to accumulate and cause the agitator to run poorly or be blocked, which needs to be improved.
