Abstract: A method of growing the ingot, including following steps: S1, providing an initial charge into a crucible; S2, heating the crucible to melt the initial charge, and after a set time, rotating the crucible at a rotation speed within a set speed range; S3, after a melting process of the charge is completed, descending a feed device to the position above the melt level in the crucible and a distance between feed device and the melt level being h, the feed device including a feed tube, and the feed tube adding a charge into a feed zone of the crucible; and S4, feeding in the feed zone, and growing an ingot in a growth zone.

Abstract: The disclosure discloses a method and a system for controlling temperature during crystal growth. The method includes that: the power of each of the heaters is constantly adjusted and simulating is performed by software to calculate the thermal field correspondingly at a solid-liquid interface and vicinity of the solid-liquid interface; the thermal field is coupled with a moving grid to determine whether the solid-liquid interface and the total thermal energy both reach thermal equilibrium; the power of each of the heaters that enables both the solid-liquid interface and the total thermal energy to reach the thermal equilibrium is stored and a thermal equilibrium diagram is drawn based on the power of each of the heaters; and during crystal growth, the power of each of the heaters is selected from the thermal equilibrium diagram which is drawn to control the temperature gradient at the solid-liquid interface.
