1 Introduction In recent years, China's steel industry has also experienced rapid development. Ferrosilicon is one of the most important products in the ferroalloy industry. It shows a rapid growth trend both in terms of production capacity and actual production. 2. Status of technical equipment of China's ferrosilicon electric furnace 2.1 The first period (1949-1985) was a period in which China's ferrosilicon electric furnace technology and equipment were in a backward state. The main performances are: small electric furnace capacity, low process level, old equipment, poor working environment and serious pollution. 2.2 The second period (from 1986 to the present) is the fastest growing period for China's ferrosilicon production. The majority of metallurgical workers clearly realized that China's ferrosilicon electric furnace technology and equipment level should be greatly improved. Must learn from foreign advanced technology. The commissioning of large-scale ferrosilicon electric furnace not only marks a solid step for China's ferrosilicon electric furnace to the world, but also demonstrates and promotes the comprehensive improvement of the technical level of China's ferrosilicon electric furnace. 3. The gap between China's ferrosilicon technology equipment and foreign advanced technology Due to the low concentration of China's ferrosilicon enterprises, they are at a stage of multi-level development. The scale of the enterprise is small, the equipment is poor, and the technology is backward. There is still a gap compared with the advanced equipment of the world ferrosilicon electric furnace. Its main performance is as follows: 3.1 Ferrosilicon electric furnace capacity is small 3.2 Small scale and low level 3.3 Poor equipment and backward technology 3.4 Poor environment and heavy pollution 4. Future development direction The number of ferrosilicon electric furnaces in China has increased, the output has increased, and the technical equipment has been partially improved. However, it is still far from being fully realized in terms of large-scale, automation and cleanliness. It should continue to move unswervingly in the direction pointed out in the outline. Go on. 4.1 Elimination of small electric furnaces with backward equipment 4.2 Renovation of medium-sized ferrosilicon electric furnace 4.3 Construction of large-scale ferrosilicon electric furnace 4.4 Implementation of Silica Iron Cleaner Production 5. Some thoughts and suggestions 5.1 Fully implement the policies formulated by the Chinese government for the regulation of the ferroalloy industry. 5.2 Improve the technical equipment level of electric furnaces, reduce labor intensity, improve working conditions and increase labor productivity. 5.3 Formulate and adhere to the industry access system, and play the role of government functions and ferroalloy professional organizations. 5.4 Organize the powerful design units and manufacturers to jointly develop the furnaces suitable for different types of ferrosilicon electric furnaces to meet the needs of China's ferrosilicon electric furnaces for large-scale and automation development.
