Abstract

The invention relates to a steel ladle edge covering structure, belonging to the technical field of steel-making steel ladle construction. The steel ladle edge covering structure is characterized in that vertical-type wedged metal press plates are welded in a discontinuous manner along the circumferential direction of a ladle opening, and thus the distribution density of the vertical-type wedged metal press plates increases; horizontal annular metal press plates are continuously welded along the circumferential direction of the ladle opening on the vertical-type wedged metal press plates, and the horizontal annular metal press plates, a covering shell and the vertical-type wedged metal press plates are welded together; wedged edge-covering bricks are matched with the vertical-type wedged metal press plates to be built, and a ladle opening ramming material is filled between the vertical-type wedged metal press plates and the wedged edge-covering bricks. The steel ladle edge covering structure has the advantages that the deformation of the press plates can be alleviated, the possibility that the bricks drop off from the covered edge can be lowered, a transverse seam in a working layer can be avoided, the turnover rate of a steel ladle can be improved, the non-planned ladle throwing can be reduced, and the service life of the steel ladle can be prolonged.

Description

technical field

[0001] The invention belongs to the technical field of steel-making ladle masonry, and in particular relates to a ladle edge structure. Background technique

[0002] A new 400mm extra-thick slab caster in a domestic steel mill was successfully put into production on June 29, 2010. The commissioning of this extra-thick slab has greatly expanded the product structure. It is a high-end product that must be processed by RH furnace The ratio has increased significantly. Since the steel ladle processed in the RH furnace is required to have no steel slag attached to the edge of the ladle, bricks on the edge of the ladle and loose bricks on the slag line often occur when processing the slag on the edge of the ladle, which seriously affects the normal turnover order of the ladle. In order to solve this problem, it is urgent to develop a new wrapping structure.

[0003] The original ladle edge structure is composed of vertical metal pressure plates and wedge-shaped e...
