How long has the single crystal furnace developed in China?

For more than 40 years, it was originally the Science and Technology Jingke of Xi'an University of Technology. Now it produces 8 series. More than 40 varieties. Zhejiang University and HAMCO of the United States cooperate to produce CG-6000 single crystal furnace, which realizes all automation from vacuuming. Shanghai Hanhong, a rising star that started production in 2005, has been well received by the industry due to its stable performance, easy operation, and high crystal formation rate.

Main requirements for purchasing technology of single crystal furnace

1. Single crystal furnace charge (how much is the capacity of a single machine) 2. How long and how many inches of silicon rods can be drawn 3. What is the yield of the drawn crystal rods 4 The quality of the drawn silicon rods (minority birth, resistivity) , Carbon and oxygen content, dislocation density) 5 equipment manufacturing process control assurance 6 automation control degree 7 the configuration of the main key components of the equipment, etc.

How to calculate the production capacity of the single crystal furnace?

The monthly production capacity is the weight of a single crystal silicon rod that a single crystal furnace can pull out in one month. It is mainly related to yield, running time and feeding amount.

The amount of molten material is the amount of material charged for each furnace,

For example, the 85 single crystal furnace can hold a 20-inch thermal field at most, and the mainstream charging volume for a 20-inch thermal field is 90KG

The 95 furnace can be equipped with a 22-inch thermal field, and the mainstream feed volume is 120KG.

I have seen the largest furnace in the country with an inner diameter of 1100, equipped with a 28-inch thermal field, and can feed 200-260KG.
