Forming preparation process of crucible special for negative electrode powder
A molding preparation process for a crucible special for negative electrode powder belongs to the field of crucibles special for negative electrode powder, and comprises the following steps: A, selecting raw materials, weighing graphitization heat preservation materials with different finenesses in parts by mass: 12-20 parts of large materials, 26-34 parts of medium materials, 16-24 parts of small materials and 30-38 parts of fine powder, mixing the materials to obtain a primary mixture, weighing 20-28 parts of modified liquid asphalt, and mixing the primary mixture with the modified liquid asphalt to obtain a secondary mixture; mixing the mixture with the primary mixture to obtain a secondary mixture; b, tempering and carburizing the crucible mold; and C, the mixture is poured into a crucible mold to be heated and pressed to be formed, and the special crucible for the negative electrode powder is obtained. The performance of the crucible is improved through cooperation of the graphitization heat preservation materials of various finenesses, the performance of the crucible mold is improved through heat treatment, then the performance of the crucible is improved, the surface hardness of the crucible is high, the homogeneity is good, and the service life is prolonged.
一种负极粉专用坩埚成型制备工艺，属于负极粉专用坩埚领域，包括以下步骤：A、选取原料，按质量份数计，称取不同细度的石墨化保温料，按质量份数计，包括大料12‑20份、中料26‑34份、小料16‑24份、细粉30‑38份，混合得到一次混合料，称取改制液体沥青20‑28份，将其与一次混合料混合得到二次混合料；B、对坩埚模具进行调质、渗碳；C、将混合料倒入坩埚模具内进行加热并压制成型，得到负极粉专用坩埚。本发明通过多种细度的石墨化保温料配合提高坩埚性能，通过热处理提高坩埚模具的性能，进而提高坩埚的性能，使坩埚表面硬度高，均质性好，使用寿命延长。
