[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] like Figure 1-2As shown, an improved ladle cover with a viewing hole comprises:

[0028] A cover body 1, wherein a viewing hole 2 is provided on the cover body 1;

[0029] A panel 3, one end of which is arranged on the outer periphery of the observation hole 2, and the other end of which is vertically upward or gradually expanded;

[0030] The protective layer 4 is arranged on the periphery of the observation hole 2 , one end of the protective layer 4 is connected to the cover body 1 , and the other end of the protective layer 4 is connected to the periphery of the enclosure 3 .

[0031] Specifically, the structural stability of the observation hole 2 is increased by the enclosure 3, and the protective layer 4 is used to prevent the observation hole 2 or the enclosure 3 from being deformed by heat, thereby preventing the heat-resistant layer inside the cover body 1 from falling off. The service life of the ladle cover is improved without changing the heat flow channel of the ladle and the function of the observation hole, and the improved operation is simple and effective.

[0032] Furthermore, the protective layer 4 is a refractory material.

[0033] In this embodiment, anchor hooks 5 for connecting the protective layer 4 are respectively provided on the cover body 1 and the enclosure 3 .

[0034] Specifically, the anchor hooks 5 are used to prevent the protective layer 4 from falling off, so that the protective layer 4 is stably covered at the observation hole 2.

[0035] In this embodiment, the anchor hook 5 includes a connection point, on which a plurality of radially arranged hook claws are arranged.

[0036] Specifically, the protective layer 4 is conveniently fixed by the anchor hook 5 . When in use, the hook claws are gathered together, and after passing through the protective layer 4 , the hook claws are spread out again, thereby fixing the protective layer 4 .

[0037] In this embodiment, the observation hole 2 is provided with a counterweight module, and the counterweight module is used to adjust the center of gravity position of the ladle cover.

[0038] Specifically, the center of gravity of the cover body 1 is prevented from shifting by balancing the weight with a counterweight block.
