AI Technical Summary
Existing composite graphite crucibles lack sufficient mechanical strength and are prone to breakage during handling, feeding, and smelting, affecting normal production and causing economic losses.
An aluminum alloy frame is nested on the outside of the graphite crucible, and through grooves and aluminum alloy blocks are set on the frame for reinforcement. Combined with an aluminum alloy heat-conducting base and ring, the mechanical strength is enhanced. Multiple movement methods are designed, such as anti-scalding grips, anti-scalding handles, and tweezers-compatible seats, to facilitate movement.
This improves the graphite crucible's resistance to external impacts, enhances its mechanical strength, and allows for convenient movement in various ways, preventing breakage and ensuring production continuity.
