Abstract

The invention belongs to the field of metallurgical desulfurization equipment, and particularly relates to a composite desulfurization blender of double-blade molten iron. The composite desulfurization blender comprises a center stirring shaft (1), a bottom stirring blade (2) and an upper stirring blade (3), wherein the bottom stirring blade (2) is fixedly connected with the lower end part of the center stirring shaft (1); a center sleeve (4) of the upper stirring blade (3) is sleeved with the center stirring shaft (1) in a sliding manner; the bottom stirring blade (2) adopts a four-blade structure; and the upper stirring blade (3) adopts a four-blade structure. By adopting the composite desulfurization blender, a composite eddy current effect is formed in a stirring region under the composite motion action of the upper stirring blade and the bottom stirring blade by adopting the bottom stirring blade and the upper blade structure of the upper stirring blade, so that the stirring efficiency of the blender is higher, and the desulfurization effect is more ideal.

Description

technical field [0001] The invention belongs to the field of metallurgical desulfurization equipment, in particular to a double-blade composite agitator for molten iron desulfurization. Background technique [0002] With the rapid development of science and technology, the requirements for steel materials are becoming more and more stringent, especially the development of offshore oil, chemical industry, automobile and other industries, which require low-sulfur or even ultra-low-sulfur high-quality steel. As a process of iron and steel production, desulfurization outside the molten iron furnace has its advantages mainly in the following aspects: (1) The desulfurization pretreatment of molten iron exerts the potential of the slag to absorb sulfur, which can improve the productivity of the blast furnace; (2) It is more important to develop the desulfurization pretreatment of molten iron The most important thing is that molten iron with very low sulfur content can be obtained, ...
