Abstract
The present disclosure provides a method for automatically controlling material suction in a process of pulling-up of a monocrystal, including the steps of: obtaining a lifetime value and a resistivity of a pulled monocrystalline silicon rod; determining the lifetime value and a ratio of the lifetime value to the resistivity of the pulled monocrystalline silicon rod; if both the lifetime value and the ratio of the lifetime value to the resistivity are greater than set values, continuing to perform a re-feeding and pulling procedure; and if the lifetime value or/and the ratio of the lifetime value to the resistivity is less than or equal to the set values, performing a segment-taking and material suction procedure.
