Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization stirring technology, and in particular to a desulfurization stirring head replacement device. Background Art

[0002] The raw materials used in steelmaking contain sulfur, which can cause steel to become hot-brittle, reducing its mechanical properties while also lowering its corrosion resistance and weldability. With the rapid development of science and technology, the requirements for steel materials are becoming increasingly stringent, especially in the development of offshore oil, chemical, automotive and other industries, which all require high-quality steel with low or even ultra-low sulfur content. Among the existing desulfurization technologies, mechanical stirring is the most widely used and most mature technology. The stirring head structure used in the stirring method includes stirring blades and a rotating rod. Since the stirring blades are immersed in high-temperature molten iron for a long time, slag will form on the surface of the stirring blades. This slag will affect the composition of the molten iron and ultimately the quality of the steel. Therefore, to ensure the quality of the molten iron, the stirring head needs to be replaced frequently.

[0003] Chinese patent CN201511023308.9 discloses a device for replacing a molten iron desulfurization stirring head and a method for replacing a stirring head. The stirring head is fixedly connected to a half-handle through a flange connector and bolts. A lifting platform is installed on a replacement trolley. After the replacement trolley reaches the bottom of the stirring head, the lifting platform rises to support the stirring head. After the bolts are removed, the lifting platform descends to remove the removed stirring head, and a new stirring head is loaded on another replacement trolley to the bottom of the half-handle. The lifting platform rises, and after the flange connector of the stirring head is docked with the half-handle, the bolts are installed, and the new stirring head is installed.
