Embodiment 1

[0021] see figure 1 and figure 2 , a high-life tundish cover, the two sides of the main structure, that is, the upper non-working surface 7 and the lower working surface 8 are designed in the shape of an arch bridge, and the bottom surfaces around are in the same plane. The main structure is a refractory molded body 2, and its interior A skeleton structure is provided, and baking holes and stopper holes 3 are reserved. A protective steel fence 1 is provided on the periphery of the main structure, and the protective steel fence 1 at the splicing seam of the cover is wrapped by refractory castables.

[0022] The skeleton structure contains a circular metal pipe network 5 that is connected, arc-shaped lines interweave, and multi-point connected to the atmosphere. The circular pipe wall thickness in the design is 15-30mm, the inner diameter is not less than 10mm, and the circular pipe is used as the skeleton bridging support ( It is only perpendicular to the length direction of ...

Embodiment 2

[0024] see image 3 and Figure 4 , a high-life tundish cover, the upper non-working surface 7 of the main structure is a plane, the lower working surface 8 is designed as an arch bridge, and the surrounding bottom surfaces are in the same plane. The main structure is a refractory molded body 2, and there are built-in The skeleton structure is reserved with baking holes and stopper holes 3, and the periphery of the main structure is provided with a protective steel fence 1, and the protective steel fence 1 covering the spliced ​​joints is wrapped by refractory castables.

Abstract

The invention discloses a high-life tundish cover, and relates to the technical field of tundish manufacturing. The cover comprises a main structure, the main structure is a fireproofing forming body,a framework structure is arranged in the main structure, a baking hole and a stopper rod hole are reserved in the main structure, a protection steel plate fence is arranged on the periphery of the main structure, the two faces, that is the upper non-work face and the lower work face, of the main structure or the lower work face is designed in an arc manner, the tundish cover of the structure is not prone to deforming or collapsing, the use safety is good, the service life is long, and compared with an existing flat plate tundish cover, the service life is prolonged by more than 20%.

Description

technical field [0001] The invention relates to the optimization and improvement of a tundish cover, relates to the technical field of tundish manufacturing, in particular to a tundish cover with good use safety and long service life, and provides a preparation method for the tundish cover. Background technique [0002] Energy saving and sustainable development are one of the important measures to maintain and improve the development of the economy. Heat insulation is one of the important measures for energy saving. It plays an important role in thermal insulation. The traditional tundish cover is made of integrally formed cast steel or cast iron, which has good integrity, but after high-temperature heat radiation, the heating is extremely uneven, and it is easy to generate large thermal stress (poor), especially in rapid cooling Under the action of rapid heat, steel castings undergo repeated phase transformations, which are prone to severe deformation and warping; at the s...
