The invention provides an integral forming manufacturing process of a crucible for a vacuum induction furnace. The integral forming manufacturing process comprises the following steps: (a) selecting an inner-layer raw material and an outer-layer raw material, (b) respectively adding high-temperature binders into the inner-layer raw material and the outer-layer raw material, (c) respectively addingwater into the inner-layer raw material and the outer-layer raw material, (d) placing a first cylinder on a plate, and placing the outer-layer raw material and the inner-layer raw material on the plate to be tamped to form a crucible bottom, (e) putting the outer-layer raw material between the first cylinder and the second cylinder, and tamping to form a crucible outer layer, (f) putting the inner-layer raw material between the graphite mold core and the crucible outer layer, and tamping to form the crucible inner layer, (g) adding the mixture to the upper edges of the crucible outer layer and the crucible inner layer, and tamping, (h) drying, (i) sintering, and (j) adding pure nickel, melting the pure nickel, and pouring out the molten pure nickel to obtain the product. The integrally formed crucible is low in cost, the service life is greatly prolonged, and the safety is high.
本发明提供一种真空感应炉用坩埚一体成型制造工艺，包括如下步骤：（a）、选取内层原料和外层原料；（b）、将内层原料和外层原料中分别加入高温粘结剂；（c）、内层原料和外层原料中分别加入水；（d）、将第一圆筒体放在板材上，并将外层原料和内层原料分别放在板材上捣实形成坩埚底；（e）将外层原料放入第一圆筒体和第二圆筒体之间捣实形成坩埚外层；（f）、将内层原料放入石墨型芯与坩埚外层之间捣实形成坩埚内层；（g）、在坩埚外层和坩埚内层上沿加入混合料，捣实；（h）烘干；（i）烧结；（j）加入纯镍，将纯镍熔化，倒出熔融纯镍，得到产品。本发明的一体成型坩埚，成本低、使用寿命大大提高，安全性高。
