Embodiment
[0023] figure 1 It is a method for improving the cleanliness of the ladle with a cover in the embodiment of the present invention, such as figure 1 As shown, the method includes:
[0024] Step 1: Judging whether the edge of the ladle meets the first preset requirement.
[0025] Further, when the ladle does not meet the first preset requirement, the ladle is edged until the first preset requirement is met.
[0026] Specifically, when controlling the cleanliness of the ladle with a lid, the edge of the ladle is firstly treated, specifically: before smelting the steel, the edge of the ladle to be used is confirmed, and when the ladle meets the requirements, no processing is performed , continue to the next step; when the requirements are not met, use special tools to carry out the hook wrapping operation.
[0027] Step 2: When the first preset requirement is met, the time from the ladle casting to slag turning is controlled within the first preset time.
[0028] Specifically,...

The invention discloses a method for improving the cleanliness of a steel ladle with a cover, which belongs to the technical field of steelmaking. By judging whether the ladle edge of the ladle satisfies the first preset requirement; when the first preset requirement is met, the steel ladle is The time from casting to slag turning is controlled within the first preset time; open the ladle cover, and when the ladle meets the first preset angle with the vertical surface, under the control of the crown block, the ladle and the vertical plane meet the first preset angle. The vertical surface satisfies the second preset angle, and lasts for the second preset time, and starts the first slag turning; after the first slag turning is completed, the ladle is adjusted to form a third preset angle with the vertical surface; The top slag of the ladle after the second slag turning is modified; the cleanliness level of the ladle is obtained according to the ladle after turning over and the preset strategy, so as to improve the cleanliness of the ladle with a cover, Improve the technical effect of accurately controlling the hit rate of the steel composition.
Description
technical field [0001] The invention relates to the technical field of steelmaking, in particular to a method for improving the cleanliness of a ladle with a cover. Background technique [0002] As the demand for high-end product performance in the steel market is getting higher and higher, precise control of molten steel composition has become a limiting link in the smelting success rate of high-end products. Perform pouring operations. The analysis found that ladle cleanliness is an important parameter affecting the precise control of molten steel composition. Therefore, how to control the cleanliness of the covered ladle has become an urgent problem to be solved. Contents of the invention [0003] The invention provides a method for improving the cleanliness of a ladle with a cover, which is used to solve the technical problems in the prior art, such as the low accurate hit rate of molten steel composition and the change of steel grade or refurbishment due to the poor...
