Embodiment 1

[0028] A method to improve the utilization rate of the silicon core masterbatch. One end of the cut silicon core masterbatch is connected to one end of the bar, and the other end of the bar is clamped in the material seat of the silicon core furnace, and then the silicon core master The material is drawn.

Embodiment 2

[0030] A method to improve the utilization rate of the silicon core masterbatch. One end of the cut silicon core masterbatch is connected to one end of the bar, and the other end of the bar is clamped in the material seat of the silicon core furnace, and then the silicon core master The material is drawn.

[0031] After the drawing is completed, the bar with the tail is removed, the tail is removed, and the bar is used continuously.

Embodiment 3

[0033] A method for improving the utilization rate of the silicon core masterbatch. One end of the cut silicon core masterbatch is connected to one end of the bar, and the other end of the bar is clamped in the material seat of the silicon core furnace, and then the silicon core master The material is drawn.

[0034] After the drawing is completed, the bar with the tail is removed, the tail is removed, and the bar is used continuously.

[0035] The silicon core masterbatch and the bar are bonded by a high-temperature adhesive.

Abstract

The invention aims to solve the problem of great wastage of silicon core master batches in the drawing process and provides a method for raising utilization rate of silicon core master batch. The method is characterized in that one end of a well-cut silicon core master batch is connected to one end of barstock, the other end of the barstock is clamped in a material seat of a silicon core furnace, and the silicon core master batch undergoes drawing. By adhering a section of the barstock to the lower end of the silicon core master batch to replace tailings, the material seat keeps a certain distance from a coil. Thus, the material seat is effectively protected, utilization rate of the silicon core master batch is raised, and cost of silicon core is greatly reduced.

Description

technical field [0001] The invention relates to the field of polysilicon production, in particular to a method for improving the utilization rate of silicon core masterbatch. Background technique [0002] Due to the energy crisis and the call for a low-carbon economy, the world is actively developing and utilizing renewable energy. Polycrystalline silicon is the main raw material for the manufacture of semiconductor devices and solar cells, and its deep-processed products are widely used in the semiconductor industry as basic materials for artificial intelligence, automatic control, information processing, and photoelectric conversion devices. At the same time, due to its cleanness, safety and abundant resources, solar energy has attracted the most attention among renewable energy sources. [0003] Among the production methods of polysilicon, the polysilicon production method (also known as the Siemens method) invented by German Siemens in 1954 is currently widely used: hig...
