I. Overview
The YTC1600 monocrystalline furnace utilizes the Czochralski method to grow single crystals, featuring a soft shaft lifting mechanism. Its working principle involves melting silicon material using a graphite resistance heater in an inert gas (argon) environment. Within a specific temperature zone, a soft seed crystal shaft lifting and rotating mechanism is employed to uniformly rotate and lift the original seed crystal. Simultaneously, the crucible rotates and ascends at a constant speed as the single crystal grows, enabling the formation of a dislocation-free single crystal rod.
II. Structure
The Czochralski monocrystalline furnace primarily consists of five major components: the furnace body, thermal system, water cooling system, vacuum system, argon gas apparatus, and electrical system. The furnace body includes the frame, main furnace body, and auxiliary furnace body. The main and auxiliary furnace bodies serve as the locations for single crystal growth, providing all necessary conditions such as vacuum levels, argon gas protection, furnace cooling, and thermal field within the furnace chamber. The electrical system mainly comprises the power cabinet and control cabinet
