Ferroalloy Ore Furnace (Industrial Silicon)

Ferroalloy ore furnace (Industrial silicon)

Technical characteristics of ferroalloy ore furnace of the company:
  Shaanxi Chengda Industrial Furnace Manufacturing Co., Ltd. combined with domestic and foreign technology development and development of new ferroalloy mineral furnace, a number of technologies and equipment in the domestic leading level.
 

Our company's advantages:
  Ferroalloy mineral furnace is a energy-saving mineral furnace introduced by our company in recent years, which has absorbed the experience of foreign equipment and combined with the specific situation of China's industrial policy. It is the optimized product of our mineral furnace and is at the leading level in China.
1,My company for many years engaged in mining furnace, short network technology development, the development of the same phase inverse parallel short network, corrected plane layout short network, inverted triangle short network, because of its short network impedance is low, low three-phase imbalance coefficient, high power factor, energy-saving effect is significant.
2, Through the in-depth study of the steel structure induction heating near the large current bus, it is proved that the high power consumption of ferroalloy is because a considerable part of the electric energy is converted into the heat of the steel structure, according to this theory, the old furnace type is newly designed, thereby creating a new type of mineral heat furnace.
3, We carefully absorb the experience of foreign advanced mineral furnace, many suitable for China's experience transplanted in our new mineral furnace, so that our company in the mineral furnace design, manufacturing, installation, commissioning has considerable advantages. The use of pressure ring instead of conical ring technology, new water-cooled cable technology and forged copper tile, the use of transformer outlet end and copper tile one to one new short network structure, so that the equipment is more advanced, higher operation rate.
4, The use of hydraulic and pneumatic technology combined with air bag lock technology, Siemens PLC control system, to achieve voltage discharge, make the electrode device more safe and reliable, improve the electrode system operation rate. When the water cooling protection sleeve is made of non-magnetic stainless steel, the power loss can be greatly reduced.
5, My company developed and produced mine furnace dust removal device, the main fan using high temperature wear-resistant technology, and the use of flexible starting mode to open the fan. The whole device adopts PLC control to make the technical performance of the device reach the domestic leading level.

Our company's industrial silicon smelting furnace construction advantages:
  Technical advantages: The company has many successful examples of the construction of the same type of industrial silicon plants at home and abroad, and can provide the overall plant and public facilities layout of the factory.

Main scope of this project:
  The design scope of supply is 2 sets of 16500KVA industrial silicon smelting furnace complete set of equipment, including: furnace body system; Smoke exhaust system; Electrode lifting system; Short network system; Hydraulic system; Iron pumping system; Cooling water system; Electric furnace transformer; High and low pressure system; Environmental dust removal system.
A full set of technical solutions can be provided as follows:
· Overall layout of industrial silicon plant;
· Industrial silicon product process;
  Including raw material crushing, cleaning preparation, weighing of ingredients, automatic feeding, automatic cloth, furnace smelting, crushing packaging, laboratory inspection and so on.

Production process selection and equipment level:
(1) Smelting varieties and output: industrial silicon, rated capacity single daily output of 28 ~ 30t;
(2) Completion and operation time: After the contract takes effect, the main plant will be completed within 4 months, and the two plants will be completed and put into operation within 5 months.
(3) Power consumption: 11500 ~ 12500KW·h/t
(4) Annual working time :330 days
(5) Selection of production process: After smelting in the industrial silicon furnace, the furnace enters the silicon pan, and directly enters the refining workshop station for oxygen blowing refining to remove impurities and improve the grade, and the hot molten liquid industrial silicon enters the nano silicon production station for factory inspection after processing, crushing and packaging.
(6) Electric furnace equipment: the same type of advanced level in China; The economic and technical index is the advanced level of the same type of electric furnace.
(7) Environmental indicators: meet China's national environmental standards.

Process description:
  Industrial silicon is smelted by electric heating in an electric furnace using reducing agents (charcoal, petroleum coke) and silica as raw materials.
Silica is washed to remove impurities such as soil; The petroleum coke is broken to a certain particle size, silica, charcoal, petroleum coke, wood blocks, etc. are weighed according to a certain ratio, transported to the four-layer platform by the loading elevator, and added to the furnace around the electrode according to the designated place of the feeding tube.
  After the charge is mixed evenly by the charging worker, it is continuously added to the furnace according to the material level of the furnace mouth, and the consumption of the core material is soon supplemented in time, and the core material should be kept full and in the shape of steamed bread.
