Crystal Grower from Vacuum Levitation Melting - EQ-SKJ-LCZ

CY is designing and developing a special CZ crystal grower from vacuum levitation melting up to 2000C.The system includes a high frequency induction heating supply,  high vacuum chamber , water cold copper crucible for levitation melting and precision pulling mechanism.Levitation melting avoids the contamination of sample from crucible and may produce high purity crystal for metallic alloys.


Structure of Grower

40KW RF Induction power source for levitation melting

Special designed water cooled copper crucible for 60 g max. metal melt levitation.

Vacuum Chamber which can reach q10-6 torr by a turbo pump system

Precision pulling system with rotary rod with speed 0.1 mm/h - 24 mm/h

 RF Induction power Source

Input power:  40KW Max.

Frequency :   80-200KHz

Current:         10-100A

Input Voltage:   200V +/-10% , Three phase, 50/60Hz

Water Cooling :Pressure  >0.2MPa  Water flow: >10L/min

Water Cold Copper Crucible

Crucible size:            ID 35mm,   Depth: 60mm

Melting Capability:      60g  Max.

Water flow required:  58L/min

Pulling Mechanism

Pulling Speed:                       0.1-24mm/h 

Pulling Rod Rotation Speed:  0.03-50r/min
