Mechanical stirring device for production of manganese-iron alloy

Abstract

The invention relates to a mechanical stirring device for production of manganese-iron alloy, and belongs to the technical field of iron alloy and casting production. The mechanical stirring device comprises a lifting motor, a lifting guide rod, an electric cabinet, a guide rail vertical column, a lifting wheel group, a lifting cross arm support, a rotating motor, a rotating guide wheel, a rotating frame and a stirring paddle, wherein the lifting cross arm support is arranged on the guide rail vertical column; the lifting system composed of the lifting motor, the lifting guide rod, the electric cabinet, the lifting wheel group, the lifting cross arm support and the like can lift the cross arm support so as to drive the stirring paddle to be lifted and lowered in a alloy liquid and a slag liquid; the rotating system composed of the electric cabinet, the rotating motor, the rotating guide wheel, the rotating frame, the stirring paddle and the like can enable the stirring paddle to rotate in the alloy liquid and the slag liquid. The mechanical stirring device has the advantages that the stirring paddle can accurately fall on the interface of the alloy liquid and the slag liquid, thus the solution stirring can be directly completed, the reaction efficiency is higher than that of the shaking ladle process, the power consumption is reduced, the recovery rate of manganese in the alloy is high, the mass fraction of manganese oxide in the final slag is far lower than that produced by using the shaking ladle process.

Description

technical field [0001] The invention belongs to the technical field of ferroalloy and casting production, and in particular relates to a mechanical stirring device for producing ferromanganese alloy, which can replace the shaking bag device of the shaking bag method, and is suitable for the production of medium and low carbon ferromanganese, or other products using the shaking bag method obtained ferromanganese alloy. Background technique [0002] At present, ferroalloy factories mainly use electrosilicothermic method and shaking bag method to produce ferroalloys such as medium and low carbon ferromanganese or high silicon ferromanganese. The electrosilicothermal method is to add manganese ore, manganese-silicon alloy and lime into the electric furnace, rely on electric heating to melt the charge, and reduce the manganese oxide in the manganese ore through silicon to produce medium and low carbon ferromanganese. The shaking bag method is to add preheated manganese ore, lime...
