Abstract
Official abstract text for this publication.
A structure of composite crucibles and a high temperature adiabatic method in an arc heating process are disclosed. The structure may include a conventional water-cooled copper platform on which one or more graphite platform(s) are disposed and the topmost graphite platform is configured for disposing one or more metallic specimen(s). When arc smelts the metallic specimen(s) in the furnace in vacuum, and the heat of the metallic specimen(s) is transferred to the graphite platform, the graphite platform can reduce heat loss and improve heat preservation so as to cause the metallic specimen(s) to remain stable for the process of heating and melting to complete. The heat of the graphite platform is further transferred to the copper platform for lowering the temperature of the graphite platform.
First claim
Opening claim text (preview).
What is claimed is: 1. A structure of composite crucibles, comprising: a copper platform; and one or more graphite platform(s) stacked with each other and disposed on the copper platform, wherein the graphite platform disposed topmost is configured for disposing one or more metallic specimen(s), and the graphite platform configured for disposing the metallic specimen(s) has at least one hole therein, and the hole is configured for disposing the metallic specimen(s), and one or more graphite platform disposed between the graphite platform configured for disposing the metallic specimen(s) and the copper platform has at least one hole configured for connecting with the hole inside the graphite platform configured for disposing the metallic specimen(s). 2. The structure of composite crucibles according to claim 1 , wherein the graphite platform contacting with the copper platform contacts with the copper platform through at least two points, such that the graphite platform is fixed on the copper platform. 3. The structure of composite crucibles according to claim 1 , wherein any of the graphite platforms contacts with another graphite platform through at least two points, such that any of the graphite platforms is fixed on another graphite platform. 4. The structure of composite crucibles according to claim 1 , wherein the area of the copper platform is greater than the area of the graphite platform. 5. The structure of composite crucibles according to claim 1 , wherein the graphite platform configured for disposing the metallic specimen(s) has at least one hole therein, and the hole is configured for disposing the metallic specimen(s). 6. The structure of composite crucibles according to claim 5 , wherein the peripheral of the hole of the graphite platform configured for disposing the metallic specimen(s) has at least one groove, and the groove is configured to fix the metallic specimen(s) to the hole more firmly. 7. The structure of composite crucibles according to claim 1 , wherein the graphite platform configured for disposing the metallic specimen(s) has at least one hole therein, and the hole is configured for disposing the metallic specimen(s), all of the graphite platforms disposed between the graphite platform are configured for disposing the metallic specimen(s) and the copper platform and the copper platform has at least one hole configured for connecting with the hole inside the graphite platform configured for disposing the metallic specimen(s). 8. The structure of composite crucibles according to claim 1 , wherein the bottom of the copper platform has a water-cooled device, and the water-cooled device is configured for exchanging heat.
