Preparation method for effectively prolonging service life of crucible and application
The invention belongs to the technical field of crucibles, and provides a preparation method for effectively prolonging the service life of a crucible and application thereof.The preparation method comprises the steps that a crucible prefabricated body is formed through ramming, and the crucible prefabricated body is formed by ramming first slurry containing graphitized coke, asphalt and carbon nanotubes, coating the inner wall of the crucible preform with a second slurry containing graphene and an organic polymer, wherein the organic polymer comprises at least one of polyethylene and polypropylene; carrying out heating and heat preservation treatment on the crucible preform at 750-850 DEG C; and then metal to be treated is added into the crucible prefabricated body, the metal to be treated is heated and melted, meanwhile, the crucible prefabricated body is sintered, the melted metal to be treated is poured out after sintering, and the crucible is obtained. The to-be-treated metal layer is formed on the inner wall of the crucible, so that the inner wall of the crucible is modified, the thermal shock resistance of the crucible is improved, melt erosion is reduced, the service life of the crucible is prolonged, dregs formed on the inner wall of the crucible are reduced, and the cleaning difficulty is greatly reduced.
本发明属于坩埚技术领域，提供了一种有效提升坩埚寿命的制备方法和用途，制备方法包括：捣制形成坩埚预制体，坩埚预制体采用包括石墨化焦、沥青和碳纳米管的第一浆料捣制形成，向坩埚预制体的内壁涂覆含有石墨烯和有机聚合物的第二浆料，有机聚合物包括聚乙烯和聚丙烯中的至少一种；对坩埚预制体在750℃～850℃下进行加热保温处理；然后向坩埚预制体内加入待处理金属，加热并熔化待处理金属，同时对坩埚预制体进行烧结，烧结后倒出熔化后的待处理金属，得到所述的坩埚。本发明在坩埚的内壁形成待处理金属层，实现对坩埚内壁进行改性，提高坩埚的抗热震性，减少熔体侵蚀，延长坩埚使用寿命，降低坩埚内壁形成渣滓，极大降低清理难度。
