Off-line processing technology of slag-iron separating and cooling device of molten iron desulfurized slag

Abstract

The invention discloses an off-line processing technology of a slag-iron separating and cooling device of molten iron desulfurized slag. The device is configured according to the two modes of off-line processing and on-line processing; when the device is configured according to the off-line processing mode, a lifting rollover device and a slag pot are arranged; and when the device is configured according to the on-line processing mode, an on-line shifting device is arranged. By adopting the technical scheme, slag and iron can further be rapidly cooled while sufficient slag-iron separating is achieved, and rapid and continuous industrial production is achieved; one set of technology is provided with two using or configuration modes, and no matter the on-line processing mode or the off-line processing mode, the core technology of the processing technology keeps consistent with equipment; conversion of the two working modes can be rapidly achieved, so that using requirements of different occasions are met, and the purposes that the using range is wide, the equipment configuration is flexible, and maintenance is simple are achieved; and the processing efficiency is improved, and the investment cost is reduced.

Description

technical field [0001] The invention belongs to the field of desulfurization slag treatment technology and equipment manufacturing in molten iron pretreatment. More specifically, the present invention relates to a slag-iron separation and cooling device for off-line processing of molten iron desulfurization slag, capable of efficiently performing slag-iron separation and cooling treatment on high-temperature desulfurization slag. The invention also relates to its corresponding treatment process. Background technique [0002] At present, in the smelting industry, the treatment of desulfurization slag mostly adopts the treatment method of spraying water to cool down and then crushing and separating. [0003] The desulfurization slag treatment process in the prior art is to arrange the slag tank at the desulfurization operation site, and the hot-melt desulfurization slag in the molten iron tank after the desulfurization operation is directly picked up from the molten iron tank...

AI Technical Summary

Problems solved by technology

[0004] The defects of the prior art treatment process are low separation degree of slag and iron and long cooling period

In addition, a large amount of water needs to be consumed to cool the high-temperature desulfurization slag during the treatment process, and a large amount of water vapor and smoke are generated at the same time, which not only wastes resources but also pollutes the environment
