Silicon Core-Furnace

Product introductionBYJ-GX06 type silicon core furnace is an electron special apparatus for drawing silicon core from polycrystalline silicon rod by a zone melting method and a high-frequency induction heating way. This furnace can steadily control the silicon core with a diameter of 6-10 mm; every furnace can draw six silicon cores. The furnace comprises: a temperature automatic control system and a motor speed control system; relative parameters of each pulled crystal comprising data such as silicon core lift, rotational speed of crucible shaft, speed for lifting the crucible, and furnace pressure can be displayed on a touching screen. Main technical parametersEach of the main technical parameters in this type is as follows:1. Finished silicon core diameter (Φ6-10)×2100 2800mm 2. Raw silicon rod diameter (Φ40-55)×600 3.
