Product Description

High Efficiency and Energy Saving Submerged Arc Furnace Equipment

Submerged Arc Furnace is an important metallurgical industrial equipment, mainly used for reducing and smelting raw materials such as ore, carbonaceous reducing agent and solvent, and mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy, etc.

Submerged arc furnaces has various specifications, and common specifications include 12500KVA, 16500KVA, 33000KVA, 40500KVA, 45000KVA, 54000KVA, 63000KVA, etc. At present, the largest SAF in operation in China is 81000KVA calcium carbide furnace and ferrosilicon furnace.
 

Product Description

High Efficiency and Energy Saving Submerged Arc Furnace Equipment

Industrial Silicon Furnace:
 
Industrial silicon furnace submerged arc furnace
The silicon smelting process mainly involves continuous submerged arc slag-free smelting in an industrial silicon furnace. During the entire smelting process.
 
Carbonaceous reducing agents (lignite, metallurgical coke, etc.) and silica are mixed in a certain ratio to form the furnace charge. The electrodes in the furnace are deeply and steadily inserted into the furnace charge, and industrial silicon is produced through arc heating chemical reaction.

Classification Of Submerged Arc Furnace

The working characteristics of the SAF include the use of carbon as the furnace lining, the use of self-training electrodes, the continuous and stable load of the transformer, low impedance voltage, more voltage regulation levels, smaller step difference, and strong overload capacity.

Submerged arc furnaces can be divided into two types: loaded and unexcited voltage regulation.

In addition, submerged arc furnace are mainly divided into two types: semi-closed and closed furnaces.
The exhaust gas generated by the closed furnace contains more combustible components and can be used for gas internal combustion engine power generation.

Our Advantages

Xi'an Sanrui's Advantages in The SAF Project

1. SR has been engaged in the research and development of submerged arc furnace and electric arc furnace short network technology for many years, and has developed in-phase and anti-parallel short network, modified planar layout short network, equilateral triangle, mid-phase non-jumping short network, due to its short network impedance. Low, low three-phase unbalance coefficient, high power factor, and significant power saving effect.

2. In-depth research on the induction heating of steel structures near high-current busbars has proved that the high power consumption of ferroalloys is because a considerable part of the electric energy is converted into heat of the steel structure. Based on this theory, a new design of the old furnace type was carried out to create A new type of submerged arc furnaces is released.

3. Use domestic advanced, mature and reliable process technology, electric furnace equipment and equipment to ensure that the electric furnace project can operate in a long-term, safe, stable and continuous manner and produce qualified industrial silicon products. Strive to achieve the best economic benefits.

4. Meet the requirements of modern enterprises for the production environment and achieve a combination of source management and tail processing. Implement the principle of controlling three wastes and reducing pollution.

5. Energy saving, consumption reduction and comprehensive utilization.

6. We have carefully absorbed the experience of foreign advanced submersible furnaces and transplanted many of the experiences suitable for our country into our new submersible furnaces, so that our company has considerable advantages in the design, manufacturing, installation and commissioning of submersible furnaces. .
