Abstract

The invention discloses a molten iron desulfurization stirrer. The molten iron desulfurization stirrer comprises a rotating shaft, and multiple stirring blades fixed on the outer peripheral edge of the rotating shaft and uniformly distributed in the peripheral direction of the rotating shaft; flow conductors are lined between two adjacent stirring blades, and are formed by surrounding triangular bottom surfaces and side surfaces outwards extending along each edge of the triangular bottom surfaces; one side surfaces of the flow conductors are bonded with the surfaces of one of two adjacent stirring blades; and the other side surfaces of the flow conductors are bonded with the surfaces of the other one of two adjacent stirring blades. The molten iron desulfurization stirrer is simple in structure and convenient for manufacturing, prominently improves the dynamic conditions of molten iron mechanical stirring desulfurization, prolongs the service life, and reduces the slag bonding between the stirring blades.

Description

technical field

[0001] The invention belongs to the field of mechanical stirring and desulfurization of molten iron before converter steelmaking, and in particular relates to a molten iron desulfurization stirrer. Background technique

[0002] KR (Kambara Reactor) stirring desulfurization method is a desulfurization technology outside the molten iron furnace that Nippon Steel began to study in 1963 and was applied to industrial production in 1965. This desulfurization method is based on a cross-shaped blade structure lined with refractory materials The agitator is immersed in the molten iron tank to rotate and stir the molten iron, so that the molten iron generates a vortex, and the weighed desulfurizer is added to the surface of the molten iron by the feeder, and is drawn into the molten iron by the vortex, and mixed and reacted with the high-temperature molten iron to achieve the purpose of desulfurization . The desulfurization method realizes the circulation contact desu...
