Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ceramic plasma sintering equipment, specifically relating to a structure of a ceramic plasma sintering material feeding device. Background Technology
[0002] Plasma sintering, an advanced sintering technology, combines plasma activation, hot pressing, and resistance heating to achieve rapid densification of materials. The process involves applying pulsed direct current (DC) through a conductive mold and material, generating Joule heating and plasma discharge between particles. Compared to conventional sintering methods, this localized heating activates and purifies the particle surface, enabling rapid bonding and densification at lower temperatures. This process is characterized by its ability to produce high-density materials with fine microstructures in a fraction of the time required by conventional sintering techniques.
[0003] However, in actual production, the cooling time has a significant impact on the final production cycle of ceramic plasma firing. Especially below 200 degrees Celsius, the cooling rate is slow, and existing technologies can only waste time waiting for the material to cool down. After it reaches room temperature, the material is removed and put into the next batch for heating. This results in the cooling time accounting for half of the entire production cycle, and the cooling time below 200 degrees Celsius accounts for half of the total cooling time, which seriously affects production efficiency.
[0004] To address the aforementioned issues, it is of great significance to develop a new type of high-temperature material handling and feeding device. This device should ensure that the graphite mold can be safely removed at 200 degrees Celsius and then placed into the next batch of materials for the next round of production. Utility Model Content
