| description | The invention discloses a device and a method for preparing an alumina crucible in an external furnace process and application, and relates to the technical field of preparation of metallurgical crucibles and intermediate alloys. The alumina crucible preparation device comprises a furnace body, a furnace cover, an outer crucible and an inner crucible. Wherein the furnace cover is located right above the furnace body, the outer crucible is located in a gap position between the furnace body and the inner crucible, and the inner crucible is hung in the center of the outer crucible through the extension support. The preparation method of the alumina crucible comprises the following steps: weighing materials, mixing the materials, charging, carrying out ignition reaction, standing, cooling and demolding. According to the method, the slag liquid formed by preparing the intermediate alloy through the outside-furnace method serves as the raw material, the aluminum oxide crucible forming and sintering process is compl |
