[0002] With the gradual promotion of fully automated crystal pulling in monocrystalline workshops, abnormal accidents such as misalignment of the thermal field, deviation of the guide tube, sparking, and crystal breaking have occurred during the crystal pulling process due to substandard installation accuracy of the thermal field, which seriously affects the workshop's production capacity and increases the cost of crystal pulling.

[0003] In the past few years, the size of the hot zone has been constantly updated in the development of the monocrystalline industry, from 26 inches, 28 inches, 30 inches, 32 inches, 36 inches, etc. As the size of the hot zone continues to increase, the installation accuracy requirements of the hot zone are getting higher and higher. It is difficult for employees to identify whether the hot zone is concentric with the naked eye, and it is also impossible to quickly and effectively find the off-center position.

[0004] Therefore, a convenient and inexpensive measuring ruler is urgently needed. To this end, we propose a positioning ruler for the hot zone installation of a single crystal furnace. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As mentioned in the background section, existing technologies often struggle to visually determine whether a thermal field is concentric, and it is also difficult to quickly and effectively locate any off-center positions. This invention proposes a positioning ruler for the thermal field of a single-crystal furnace.

[0024] Example 1

[0025] Reference Figures 1 to 4 A positioning ruler for the hot zone of a single crystal furnace, comprising: a horizontal ruler 1;

[0026] A main scale 2 is installed around the four sides of the level 1, and the main scale 2 is 500 cm long.
