Steel ladle

Abstract

The embodiment of the invention discloses a steel ladle. The steel ladle comprises a ladle cladding, a working lining and a pressing plate. The working lining is arranged in the ladle cladding and comprises ladle wall lining bricks, ladle edge lining bricks and a ladle edge pouring lining, wherein the ladle edge lining bricks are built on the ladle wall lining bricks, the pressing plate is arranged between the ladle edge lining bricks and the ladle edge pouring lining and fixed to the ladle cladding, the pressing plate is made of a heat-resistant cast iron pressing plate and comprises a bottom plate, brace bars and a fixing plate matched with the inner wall of the ladle cladding, the bottom plate extends in the thickness direction of the fixing plate, the fixing plate is fixed to the ladle cladding through bolts, and the bracing bars are fixed to the bottom plate and the fixing plate respectively.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a steel ladle. Background technique [0002] The ladle is a container for storing molten steel and an integral part of refining equipment. A traditional ladle structure is shown in Figure 1, the ladle includes a cladding 111, an insulating layer 103 and a lining (not shown in the figure), wherein the insulating layer 103 is arranged between the cladding 111 and the lining; the lining includes The working lining and the permanent lining 102, the working lining is in direct contact with the molten steel, and the permanent lining 102 is in direct contact with the insulation layer 103; the working lining includes the bottom pouring lining 105, the wall pouring lining 104, the wall lining brick 101, The lining bricks 107 and the pouring lining 106, wherein, the bottom casting lining 105 and the wall casting lining 104 are integrally cast through the working lining casting const...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned ladle is in use, the sticky slag on the edge of the ladle gradually increases, and the molten steel cannot enter the LF and RH molten steel refining furnaces after the edge of the ladle is super high.

When dealing with sticky slag along the ladle, it is easy to damage the pouring lining and brick lining along the ladle, and is forced to repair the ladle edge off-line, which affects the turnover rate of the ladle and the service life of the lining

In order to solve the above problems, a pressure plate is provided at the edge of the cladding. The pressure plate is an ordinary steel plate, which is welded to the edge of the cladding in blocks. The service life of the edge, so the pressure plate needs to be replaced regularly

Due to the poor working environment on site and the long replacement time of the pressure plate, the labor intensity of the maintenance personnel is high
