What is The Temperature of a Submerged Arc Furnace?

Submerged arc furnace require high temperatures for efficient metal extraction and reduction reactions. These extreme temperatures ensure the effective chemical reactions required for metal smelting, resulting in highly efficient production.

SAF submerged arc furnaces temperature typically range from 1350°C to 2000°C, depending on the type and application. For example, ferroalloy furnaces range from 1600°C to 1750°C, while calcium carbide furnaces reach temperatures as high as 1900°C to 2000°C to meet the requirements of metal extraction and reduction reactions.

What Metals Are Submerged Arc Electric Furnace Used To Smelt?

SAF generally refer to high-temperature smelting furnaces, such as leaching furnaces, rotary kilns, and flat-top furnaces in pyrometallurgy. They are also sometimes referred to as submerged arc furnaces. They are widely used in the smelting and refining of the following metals:

• High-temperature treatment in iron and steel smelting and alloying processes;

• Copper extraction, blister copper smelting, and the smelting process in copper production;

• Bauxite pretreatment, alumina reduction furnace processes, and high-temperature treatment of aluminum alloys. High-temperature treatment during the smelting and purification of nickel, chromium, and their alloys.

• Non-ferrous metals such as lead, zinc, silver, and gold. For example, the separation and purification of multi-metal systems during high-temperature smelting.

• Metals such as manganese, tungsten, and molybdenum. Smelting and purification under specific process conditions.

• Extraction of precious and rare metals.

Temperature Ranges of Different Types of Submerged Arc Furnace

• Silicon-chromium furnaces: Temperature range 1600-1750°C.

• Silicon-manganese furnaces: Temperature range 1350-1400°C.

• Calcium carbide furnaces: Temperature range 1900-2000°C.

• Ferroalloy furnaces: Operating above 1600°C.

Major Factors Affecting Submerged Arc Electric Furnace Temperatures

The specific conditions vary depending on the SAF furnace type, process, raw materials, and equipment, but most submerged arc furnace affected by the following factors. 

1) Raw material properties

2) Coal gas/combustion system

3) Reaction thermodynamics and kinetics

4) Furnace design and thermal parameters

5) Energy management and operating procedures

6) Operation and maintenance factors

7) Safety and environmental constraints
