What are the advantages of DC electric arc furnaces and DCsubmerged arc furnace？

March 09, 2024

1. Energy saving and efficiency: DC arc furnaces can effectively convert electrical energy into thermal energy, reduce energy loss, thereby improving smelting efficiency and increasing product yield.

2. Environmental protection: DC arc furnaces do not use fuel, so they do not produce harmful gases or solid waste, and can reduce environmental pollution by reusing waste such as steel.

3. Strong adaptability: DC arc furnaces are widely used in various fields such as metallurgical industry, mechanical processing, and casting industry due to their fast and stable arc, low noise, low electrode consumption, and flexible controllable temperature adjustment and heating capabilities.

4. Small impact on the power grid: DC arc furnaces have a smaller impact on the power grid and do not require dynamic compensation devices, which helps to extend the service life of cables.

5. Cost reduction: DC arc furnaces can shorten smelting time, reduce refractory material consumption, lower metal consumption, and thus accelerate the investment return cycle.

6. High yield: During the smelting process, the DC arc furnace can accurately control the heating temperature and time, allowing the raw materials in the furnace to be fully melted and mixed. At the same time, appropriate alloying treatment can be carried out to improve product quality.
In summary, DC arc furnace is an efficient and environmentally friendly smelting equipment, suitable for multiple industrial fields, and also has great economic advantages.
