Description

Technical Field

[0001] The present invention relates to the technical field of hot desulfurization slag recycling, and in particular to a slag pan for hot desulfurization slag recycling. Background Art

[0002] At present, a large amount of cold desulfurizer needs to be added during the desulfurization of KR molten iron pretreatment in steel plants, resulting in a large temperature drop during the molten iron treatment process. The desulfurizer will condense and grow into a spherical substance with a diameter of several millimeters to tens of millimeters when being drawn into the molten iron, causing the desulfurizer to be unable to undergo a chemical reaction inside and directly enter the slag for removal. The removed desulfurized slag is generally transported to the slag treatment workshop in a slag tank and directly treated by sprinkling water and heating, resulting in low desulfurizer utilization and a lot of solid waste. The hot desulfurized slag recycling technology can solve this problem by adding the hot desulfurized slag back into the iron ladle for secondary use, so it has broad market prospects.

[0003] However, the existing slag pot tipping is all done by using a crane auxiliary hook, which makes it difficult to achieve automatic control. Utility Model Content

It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] At present, a large amount of cold desulfurizer needs to be added during the desulfurization of KR molten iron pretreatment, which causes a large temperature drop during the molten iron treatment process. The desulfurizer will condense and grow into a spherical substance with a diameter of several millimeters to tens of millimeters when being drawn into the molten iron, making it impossible for the desulfurizer to undergo a chemical reaction inside and directly enter the slag for removal. The removed desulfurization slag is generally transported to the slag treatment workshop in a slag pot and directly treated by sprinkling water and heating. This results in low desulfurizer utilization, a large amount of solid waste, and other problems. The hot desulfurization slag recycling technology can add the hot desulfurization slag back into the iron ladle for secondary use, which can solve this problem well and therefore has broad market prospects. However, the existing slag pot tilting method uses a crane auxiliary hook, which makes it difficult to achieve automatic control.
