After washing, screening, and drying the raw material silica, metal silicon is batched in different proportions according to the type of reducing agent used. Various material proportions are controlled by computer programs, and collected from the material factory warehouse onto a belt. The materials are fed into the production process for mixing and enter the electric furnace. The highly automated and large-scale feeding process is continuous. An electric current is connected to the electrode to heat the material inside, reaching a high temperature of over 1800 degrees Celsius. Silicon is reduced in the intracranial region and exhibits liquid changes. It is released through the silicon outlet and cast into silicon ingots, which are then crushed and packaged into industrial silicon powder for sale. The method of mixing oxygen and air for bottom blowing is adopted. The breathable bricks for bottom blowing oxygen are installed in the bottom of the package, and there are many fine copper pipes inside the breathable bricks. Oxygen and air are blown from the fine copper pipes into the silicon melt for refining. After the oxygen blowing is completed, the air also forms a positive pressure into the silicon melt through the breathable bricks. The refining process requires more stirring, which is carried out using the principle of compressed air. Its purpose is to establish dynamic conditions for the reaction of metal elements in the material, accelerate slag formation, remove impurities as soon as possible, and reduce heat loss and silicon liquid sticking.
