Embodiment 1

[0026] combine Figure 1 to Figure 3 A warning brick for working lining of tundish is provided, which includes a first brick body and a second brick body. In this embodiment, the first brick body and the second brick body are two sections of cylindrical brick bodies with different cross-sectional areas, wherein The first brick body is the first brick body 5 of the warning brick, and the second brick body is the second brick body 6 of the warning brick. 5. Fixed connection with the second brick body 6 of the warning brick, the radial dimension of the first brick body 5 of the warning brick is smaller than the radial dimension of the second brick body 6 of the warning brick, and the greater the difference between the two, the center of gravity of the warning brick will be far away from the tundish The inner cavity 4 and the first brick body 5 of the warning brick will be consumed layer by layer during use, and will not fall directly as a whole due to an unstable center of gravit...

Abstract

The invention discloses a warning brick for a tundish working lining and a preparation method of the warning brick, and relates to the technical field of steelmaking equipment. The warning brick comprises a first brick body, wherein the first brick body is fixedly connected with a second brick body, the radial size of the first brick body is smaller than that of the second brick body, the longitudinal axis of the first brick body is parallel to that of the second brick body, the projection of the first brick body in the thickness direction is completely located in the projection area of the second brick body, and the bottom shape of the second brick body is matched with the surface of a tundish permanent lining; and the total axial thickness of the first brick body and the second brick body is not smaller than 1 / 2 of the thickness of the working lining, and the axial thickness of the second brick body is 1 / 5-1 / 3 of the thickness of the tundish working lining. According to the warning brick for the tundish working lining, an operator can accurately judge the erosion thickness of the working lining by observing the height of the warning brick bulging out of the working lining in the thermal state, when the residual thickness of the working lining reaches a design value, the second brick body of the warning brick can conduct early warning, the using thickness of the working lining is ensured to reach the optimum, and the use safety of the tundish is improved.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment, in particular to a warning brick for working lining of a tundish and a preparation method thereof. Background technique [0002] The tundish is an intermediate container connecting the ladle and the crystallizer in the steelmaking production process, and has the functions of diversion, continuous pouring, decompression, protection and refining. The components of the tundish lining are: thermal insulation layer, permanent lining, and working lining. Among them, the working lining is directly in contact with molten steel, which is a key part. The selection of materials is particularly important. The working lining material has been developed from the original refractory brick and heat insulation board. Up to now, the paint and dry vibrating material, although the existing materials have been greatly improved, but the working lining of the tundish is in direct contact with molten steel...
