An automatic temperature stabilization process

Abstract

The invention provides an automatic temperature stabilizing technology. The technology comprises following steps: S1, seed crystals drop automatically and are positioned to the original seed crystal position; S2, seeding power is recorded automatically, automatic cooling is performed, and the liquid level temperature of a silicon solution is adjusted to the welding temperature; S3, automatic overheating welding is performed; S4, automatic cooling is performed; S5, the temperature is maintained according to the automatically recorded seeding power, and temperature stabilizing is completed. Theautomatic temperature stabilizing technology has beneficial effects as follows: the technology comprises steps of automatic dropping of the seed crystals, automatic temperature adjustment, automatic recording of the seeding power, automatic overheating welding and automatic cooling, the automatic temperature stabilizing is realized, the temperature stabilizing labor-hour is shortened, the yield isincreased, the degree of automation is high, the competitiveness of an enterprise is improved, the labor intensity is reduced, and the working efficiency is improved; compared with manual operation,the technology is more accurate, scientific and unified, labor-hour waste caused by inadequate manual experience is avoided, the safety is high, and abnormal accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of Czochralski single crystal, and in particular relates to an automatic temperature stabilization process. Background technique [0002] At present, the competition in the industry is becoming increasingly fierce, and cost reduction and efficiency increase have become a magic weapon for an enterprise to survive. At present, in the production process of solar photovoltaic material manufacturing, except for the equal-diameter process state (automatic has been realized), the operation is the most difficult and takes the longest time. The state of the art process is temperature stabilization. At present, the manual temperature stabilization method is generally used in the industry. The manual temperature stabilization method is very dependent on operating experience, and requires the continuous attention of the operator, which takes up a lot of manual energy and practice. [0003] The current industry average ...
