Description

Technical Field

[0001] The present invention relates to the technical field of silicon core detection, and particularly to a detection device for silicon core production. Background Art

[0002] The main purpose of silicon core production detection is to ensure the stable performance of silicon core tubes under different environmental conditions, help identify material defects, manufacturing flaws, and other potential problems, so as to avoid failures in actual applications. This is of great significance for ensuring the safety of engineering projects and extending the service life of equipment.

[0003] The Chinese patent with the patent announcement number CN211872149U discloses a silicon core furnace capable of measuring the diameter of a silicon core. The device completes the pushing of a buffer rod through the extrusion of a spring and contacts a pressure sensor to achieve the effect of measuring the silicon core. The device has a simple structure and is convenient to operate. However, the device is arranged inside the furnace body, and the internal temperature is relatively high during operation.
