Introduction of Submerged Arc Furnaces
Submerged arc furnaces is particularly suitable for the field of metallurgy, especially for the smelting of ferrosilicon, silicon manganese, silicon aluminum and other ferroalloys. Its working principle relies on arc heating technology, which melts the raw materials and reacts chemically through high-temperature arc.
SAF consists of a pre-electrode, a furnace body, a conductive furnace bottom and a rectifier power supply. The top electrode is composed of three electrodes arranged in an equilateral triangle in the center of the furnace, serving as the negative electrode and connected to the negative electrode of the rectifier through a copper bus and a soft copper wire; the metal bottom electrode is led out from both sides of the furnace bottom and connected to the positive electrode of the rectifier through a soft copper wire and a copper bus.

Submerged Arc Furnaces Smelting Process
Key points of SAF smelting process
Smelting temperature
The maximum temperature of the submerged arc furnaces smelting process can reach 1300℃, which mainly depends on the solubility and melting point of the compound to be smelted.
Timing & amount of feeding
During the smelting process, the timing and amount of feeding should be considered. The timing of feeding depends on the oxide content of the substance generated by electrolysis and the change of the capacity of the SAF. The amount should be determined according to the actual production situation to ensure the effectiveness of the submerged arc electric furnace smelting process.
Smelting time
The time of the SAF smelting process should be controlled to ensure the quality of the smelted product. Generally speaking, the smelting time of the mixture is about 2-4 hours.
Control of smelting temperature
During the smelting process, the change of temperature has a very important influence on the quality of the smelted product. Sometimes it is lower than the lowest temperature of the furnace, and sometimes it is higher than the highest temperature of the furnace. It is necessary to control the content of oxides and the volatilization of water. The temperature control should be flexible and direct heating and cooling should be controlled.
Submerged Arc Melting Furnace Smelting Process Flow
Raw material heating: Put the mixture to be smelted into the submerged arc furnace, and arrange air to be sent into the electric furnace to heat the mixture until its internal temperature is low.
Electrolytic ionization: Convert the mixture into tantalum compounds, ionize them through electrolysis, and extract the minerals from the tantalum compounds to achieve the smelting purpose.
Continue smelting: Add the mixture to be smelted and the minerals generated by electrolysis into the 9 MVA submerged arc furnace for further smelting.
Adjust airflow & temperature: When the airflow and temperature adjustment settings are appropriate, the target smelting period reaches the critical point of radioactive material reduction, and a lower concentration of minerals (or other minerals) can be obtained.
Cooling & storage: Stop heating, cool the smelted product to room temperature, take it out and store it in the warehouse required for final processing.
