Product Overview/产品概述:
Industrial silicon is also called crystalline silicon. The main use of industrial silicon is as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for silicon steel with strict requirements, and as a deoxidizer for smelting special steels and non-ferrous alloys. After a series of industrial treatments, industrial silicon can be drawn into single crystal silicon for use in the electronics industry.
Product Introduction/产品介绍:
Industrial silicon is now widely used in alloy preparation, preparation of high-purity semiconductor materials, production of solar cells, production of temperature-resistant materials and silicone. Today’s society has entered the information age, and it has been widely used in scientific research and various fields such as electrical, aviation, machinery, chemical, medicine, and national defense in industrially developed countries.
Industrial silicon production is a high-energy-consuming industry, and an average of more than 13,000KWh of electricity is consumed per ton of industrial silicon. The high energy consumption of industrial silicon production is mainly due to unreasonable design, low control and management levels.
The unreasonable design is reflected in the commonly used small furnace type of about 6300KVA (large heat dissipation and low output), the furnace design is not strict in insulation measures, the circuit design is unreasonable, the size of the polar center circle is unreasonable, and many other details.
We are a professional furnace design and manufacturing manufacturer. The energy saving methods we are currently considering in industrial silicon production are mainly:
1) Large-scale furnace type;
2) Sealed furnace type;
3) Waste heat utilization;
4) Measures to improve furnace electrical efficiency such as improving short-net structure design, improving transformer performance, improving electrical parameters, using low-frequency power supply, etc.;
5) Improving furnace thermal efficiency;
6) Changing the reaction mechanism in the furnace;
7) Changing the performance of raw materials;
8) Using automatic control;
9) Management system construction.
Through years of exploration and discussion, the average electrical efficiency of China’s industrial silicon arc furnace is above 92%. Our company is also relatively mature in various technologies or measures to improve electrical efficiency, such as improving short-net structure design, using high-quality conductive materials, using low-voltage compensation technology, and improving electrical parameters.
At present, our company has more experience and greater advantages in the research of large-scale furnace type, sealed furnace type, waste heat utilization, and thermal insulation design technology.
