Problems solved by technology
[0004] The current crucible has a solid structure. In solar metallurgy technology, when used as a metallurgical container, the quality of metallurgical materials will be seriously affected due to the intermittent nature, visibility and inability to irradiate the sun source all the time.
Especially in areas with insufficient light and many rainy days, the metallurgical efficiency will be seriously reduced, and in severe cases, the entire smelting process will be suspended or scrapped, which is a huge waste of human resources, raw material resources and energy.

The invention discloses a graphite crucible for solar metallurgy and a solar metallurgical device using the crucible. The graphite crucible for solar metallurgy comprises a crucible body and a crucible base, wherein the crucible base is a hollow structure; conductive molten salt is arranged in the inner cavity of the crucible base; a groove is further formed in the crucible base; and the outer side wall of the crucible body is further attached with a resistance heating wire and a thermal insulation layer. According to the graphite crucible for solar metallurgy and the solar metallurgical device using the crucible provided by the invention, the base provided with the groove and having the hollow structure is adopted, and a matching part is wound with the graphite curable formed by the crucible body in which an electric heating wire is added, so that heat energy supply, during rainy days or light deficiency, of the graphite crucible can be effectively improved, and therefore, the purpose of improving smelting result and smelting quality is achieved.
Description
technical field [0001] The invention relates to the field of solar metallurgy, more specifically, the invention relates to a graphite crucible for solar metallurgy and a solar metallurgy device. Background technique [0002] Solar energy is being used more and more as a clean and renewable energy source. Tower-type solar metallurgy uses the sunlight reflected by the solar heliostat system to heat the metallurgical container on the receiving tower, so as to achieve the purpose of smelting metal. This method has a high utilization rate of solar energy. Compared with the traditional method of using solar energy to generate electricity and then using electric energy for metallurgy, the equipment and process can be greatly simplified, and the occupied area is small. [0003] Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heating ...
