Abstract: The present application provides an apparatus and a method for ingot growth. The apparatus for ingot growth comprises a growth furnace, a crucible, a heater, a lifting mechanism, an infrared detector, a dividing disc, a sensor and a control device. The crucible is located within the growth furnace. The lifting mechanism comprises a lifting wire and a driving device, wherein the lifting wire connects to the top of the ingot via one terminal and to the driving device via another terminal. The bottom of the ingot puts inside the crucible, and the ingot has plural crystal lines thereon. The infrared detector is located outside the growth furnace. The dividing disc is above the growth furnace, connects to the lifting mechanism, and rotates with the ingot synchronously under the driving of the lifting mechanism, and an orthographic projection of bisector of the dividing disc is between two adjacent crystal lines. The sensor is located on the periphery of the dividing disc.
