The main production processes of industrial silicon include:

1. Silica and reducing agent are automatically added to the submerged arc furnace according to a certain proportion of weight. The furnace material is heated to above 2000 degrees Celsius, and silica is reduced by carbon reducing agent to generate industrial silicon liquid and carbon monoxide (CO) gas. CO gas escapes through the material layer and preheats the furnace material.

2. Inject a mixture of oxygen and air at the bottom of the silicon water bag to remove other impurities such as calcium and aluminum.

3. Transport the silicon water ladle to the casting room through an electric charter car to cast silicon ingots.

4. After cooling the silicon ingot, it is crushed, graded, weighed, packaged, and stored to obtain the finished silicon block.

5. The flue gas enters the flue through the smoke hood at the furnace mouth, and after being treated by environmental protection facilities such as air coolers and fans, enters the bag filter for dust removal, and meets the national emission standards.
