[0012] Preferably, two concave clamping grooves are provided on the top of the ceramic cover.

[0013] Preferably, a slot matching the reinforcing portion extending out of the bottom of the crucible body is provided on the end surface of the ceramic cover.

[0014] Preferably, the crucible body, the reinforcement portion, the annular support and the annular clamping seat are made of a single piece of material.

[0015] Preferably, the crucible body is made of coarse particles added with sintered polycrystalline stone, electrical corundum, silicon carbide and fused zirconium dioxide to form a micro-crack structure.

[0016] Preferably, the protective layer is made of zirconium disilicide material.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a ceramic crucible for high-temperature alloys. In a high-temperature use environment, the protective layer arranged in the crucible body effectively reduces the influence of air erosion on the crucible body. At the same time, the open end of the crucible body is covered by the ceramic cover body, and a discharge channel for hot air is formed between the side wall of the crucible body and the inner wall of the annular clamping seat, and between the gaps of the two adjacent reinforcement parts, which effectively avoids the influence of air erosion on the crucible body caused by the entry of air. At the same time, the reinforcement parts provided support the crucible body as a whole, avoiding deformation of the crucible barrel. After use, the reinforcement part extending out of the bottom of the crucible body is inserted into the ceramic cover body, so that the crucible body can be stored conveniently.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a ceramic crucible for high temperature alloys, comprising: a crucible body 1; a plurality of reinforcement parts 2 are provided, which are arranged around the side wall of the crucible body 1, and the lower end extends out of the bottom of the crucible body 1; an annular support 3 is arranged on the outer wall of the plurality of reinforcement parts 2; the annular support 3 is used to place the ceramic crucible on the mounting frame, and an annular clamping seat 4 is arranged on the outer wall of the plurality of reinforcement parts 2 and is located above the annular support 3; the annular clamping seat 4 is arranged to facilitate users to clamp the ceramic crucible, and a ceramic cover 5 is installed on the annular clamping seat 4; a protective layer 8 is arranged on the inner wall of the crucible body 1, and the crucible is used at high temperature In the environment, the protective layer 8 arranged in the crucible body 1 effectively reduces the influence of air erosion on the crucible body 1. At the same time, the open end of the crucible body 1 is covered by the ceramic cover 5, and a discharge channel for hot air is formed between the side wall of the crucible body 1 and the inner wall of the annular clamping seat 4, and the gap between the two adjacent reinforcement parts 2, which effectively avoids the influence of air erosion on the crucible body 1 caused by the entry of air. At the same time, the reinforcement part 2 provided supports the whole of the crucible body and avoids deformation of the crucible barrel. After use, the reinforcement part 2 extending out of the bottom of the crucible body 1 is inserted into the ceramic cover 5 to facilitate the storage of the crucible body 1.
