Abstract

The invention belongs to the technical field of KR desulfurization, and discloses a stirring device for a KR desulfurization method. The stirring device comprises a driving motor, a speed reducer, a stirring shaft, a stirring head, a stirring bracket and a diversion column; the driving motor is connected to the speed reducer, and fixed to the stirring bracket; one end of the stirring shaft is connected to the speed reducer; the other end of the stirring shaft is connected to the stirring head; and the diversion column is fixed to the stirring bracket, and arranged with the stirring shaft sideby side. The invention provides the stirring device and method, with the advantages that the stirring efficiency can be improved, and the desulfurizer consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of KR desulfurization, in particular to a stirring device and a stirring method for the KR desulfurization method. Background technique [0002] KR (Kambara Reactor) desulfurization method is the main method of hot metal pretreatment technology at home and abroad at this stage. It mixes hot metal and desulfurizer through mechanical stirring, which improves the dynamic conditions of the desulfurization process and achieves the purpose of rapid desulfurization. The KR desulfurization method is widely used by iron and steel enterprises at home and abroad because of its stable equipment and simple operation. [0003] The KR desulfurization method needs to immerse the refractory material stirring head into the molten iron to a certain depth, and mix the molten iron with the desulfurizing agent through the high-speed rotation of the stirring head. During the stirring process, due to the high-speed rotation of the...
