Description

Technical Field

[0001] The utility model belongs to the technical field of steelmaking production, and particularly relates to a steelmaking iron oxide scale cleaning device. Background Art

[0002] In steel mills, the main function of the swirl well is to collect the scale produced during the continuous casting process to achieve the purpose of recycling, environmental protection and energy saving. The secondary cooling water of continuous casting is directly sprayed from the continuous casting nozzle onto the ingot, including some other open-circuit cold water, and collected in the slag flushing ditch under the continuous casting machine. The scale of iron oxide that falls from the steel ingot in the slag flushing ditch is all flushed into the swirl well from the slag flushing ditch. After the scale of iron oxide settles in the swirl well, it needs to be cleaned out, and then it can be forced back to the water treatment station by a circulating pump for recycling after water treatment and purification. The cleaned scale of iron oxide has a comprehensive total iron content of about 70%, and has a high recycling value. While improving the steel material, it can effectively increase the iron oxide content in the slag of the converter blowing process, reduce the splashing phenomenon caused by back drying in the middle and late stages, and achieve the purpose of reducing costs, increasing efficiency, and environmental protection and energy saving.

[0003] Traditionally, most of the iron oxide scale is collected by manual underwater operations and then bagged for recycling. Failure to clean it in time will cause blockage inside the vortex well, increase the phenomenon of iron oxide scale hardening at the bottom of the vortex well, increase the labor intensity of employees, and pose major safety hazards. The cleaning and recycling time is long, affecting the rhythm of steelmaking production. There is also a method of using a crane with a grab bucket for processing, which is also inefficient.
