Under the influence of multiple external factors, DC electric arc furnaces suffer from severe arc deviation and low thermal efficiency. However, there is no effective method in related technologies to quantitatively analyze the interference effects of different factors on the DC electric arc, seriously hindering the widespread adoption and operation of DC electric arc furnaces. To address these problems, embodiments of the present invention propose a DC electric arc influencing factor analysis device, a DC electric arc influencing factor analysis method, an electronic device, and a computer-readable storage medium. These embodiments will be described in detail below.
