A submerged arc furnace is a common heat treatment equipment that heats ore to high temperature through electricity or fuel to achieve melting, refining, or heat treatment of the ore. The working principle of a submerged arc furnace mainly includes three aspects: energy transfer, heat transfer, and material conversion.
Firstly, the working principle of a submerged arc furnace involves energy transfer. Usually, a submerged arc furnace generates energy through electricity or fuel, which is then transferred to the ore. Under the action of energy, the atoms within the molecule begin to vibrate more violently, the interaction between atoms becomes stronger, and the temperature of the ore gradually increases.
Secondly, the working principle of a submerged arc furnace also involves the heat transfer process. A submerged arc furnace transfers heat from the combustion chamber to the ore through three methods: radiation, conduction, and convection. Radiation refers to the transfer of heat in the form of electromagnetic waves. The high-temperature combustion chamber in a mining furnace emits a large amount of thermal radiation, which directly irradiates the surface of the ore, causing its temperature to rise. Conduction refers to the transfer of heat through molecules within a substance. Molecules in the high-temperature region of an ore are transferred to molecules in the low-temperature region, gradually homogenizing the temperature of the entire ore. Convection refers to the transfer of heat through the flow of gas or liquid, and the airflow or liquid flow in a submerged arc furnace can accelerate the rate of heat transfer, making the ore more evenly heated.
Finally, the working principle of a submerged arc furnace also involves the material conversion process. In high-temperature environments, the internal molecular structure of ores may change, and ores may melt, melt, evaporate, or undergo chemical reactions. For example, metal ore will melt into liquid metal at high temperatures, and impurities in the ore will be oxidized or reduced to achieve ore refining or purification.
In summary, the working principle of a submerged arc furnace mainly includes three aspects: energy transfer, heat transfer, and material conversion. Through energy transfer, a submerged arc furnace transfers energy to the ore, causing its temperature to rise; Through heat transfer, the submerged arc furnace transfers heat from the combustion chamber to the ore, making it evenly heated; Through material transformation, ore undergoes structural changes in high-temperature environments, achieving melting, refining, or heat treatment of the ore. The working principle of a submerged arc furnace provides a foundation for the heating and treatment of ores, and is widely used in fields such as metallurgy, chemical engineering, and materials science.
