AI Technical Summary
In the existing technology, quartz crucibles and carbon-carbon crucibles are difficult to separate. Conventional manual tapping methods are inefficient and easily damage the carbon-carbon crucibles, resulting in operational difficulties and increased costs.
Design an electromagnetic breaker that uses an electromagnetic coil to drive an active hammer, which strikes a quartz crucible with an alloy hammer tip. Combined with a limiting spring and a sliding cover, the striking depth is limited to achieve stable crushing and avoid splashing and damage to the carbon crucible.
This technology enables efficient crushing of quartz crucibles, reducing labor intensity and production costs while improving operational safety and equipment lifespan.

Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of practical crucible breaking, and particularly relates to an electromagnetic breaking hammer. BACKGROUND
[0002] In a single crystal silicon furnace, by wrapping a carbon-carbon crucible outside a quartz crucible, the silicon material in the quartz crucible is melted by directly heating the outer crucible through a heater, and the quartz crucible is softened and attached to the carbon-carbon crucible at a temperature exceeding 1500 degrees Celsius. After the single crystal silicon rod is drawn, the quartz crucible has a low thermal expansion coefficient and is not obviously contracted, while the carbon-carbon crucible has a high thermal expansion coefficient and is obviously contracted, so that the quartz crucible is tightly clamped inside the carbon-carbon crucible during the cooling process, and the quartz crucible and the carbon-carbon crucible are difficult to separate.
[0003] The conventional treatment method is to manually knock the quartz crucible to cause the quartz crucible inside the carbon-carbon crucible to break, and finally realize the separation of the quartz crucible from the carbon-carbon crucible by continuously removing the broken quartz crucible pieces. However, the whole operation process is low in efficiency and high in labor intensity, and the knocking vibration is strong. At the same time, since the wall thickness of the quartz crucible clamped tightly in the crucible band of the carbon-carbon crucible is different at different positions after cooling, the carbon-carbon crucible band is easily knocked during knocking.
