Introduction of metal silicon smelting production technology

Silicon metal (also known as industrial silicon) is a kind of industrial silicon extracted from quartz stone (silicon dioxide), which can be widely used in electronics, optical fiber, solar products, construction, medical, chemical, machinery and metallurgy, rubber and insulation materials, high temperature coatings and other industrial and civil aspects.

It can be said that silicon is an indispensable raw material for solar energy products after coal and oil. According to the UK? A metal guide? Report: In the future, the world metal silicon consumption will increase by an average of more than 3.9% per year. Japan, the United States and other western countries are large users of silicon, and China is a major industrial silicon production and export country. At present, although there are more than 300 production enterprises in China, it is generally a small electric furnace below 6300KVA, high energy consumption, low efficiency, and more than a dozen enterprises with a production capacity of more than 20,000 tons.

Before the 1990s, people's attention to mineral resources mainly focused on rare metals, non-ferrous metals, coal and construction raw materials.

With the development of industry and science and technology, a large number of semiconductors, solar energy, synthetic metals and other materials are widely used, making the demand for industrial silicon gradually rise, especially silicon aluminum alloy, concrete, fireproof materials and hard glass processing and other external silicon demand is huge!
