The invention discloses a graphite electrode capable of performing preheating treatment and applied to an electric arc furnace. The graphite electrode comprises a support frame, a drive motor, a graphite electrode main body and an electrode tip, wherein the drive motor is bolted and fixed on the support frame, furthermore, the graphite electrode main body is arranged on the right side of the support frame, the electrode tip is inlaid at the lower end of the graphite electrode main body, a first limit plate is arranged on the left side of the lower end of the graphite electrode main body, a second limit plate is arranged on the right side of the first limit plate, a third limit plate is arranged above the first limit plate, and a fourth limit plate is arranged on the right side of the thirdlimit plate. The graphite electrode capable of performing preheating treatment and applied to the electric arc furnace is provided with an electric heating wire, a graphite electrode can be subjectedto preheating treatment through the electric heating wire after the graphite electrode main body is fixed by the limit plates, so that the graphite electrode main body has a certain initial temperature, damage to the inside of the graphite electrode main body due to subsequent relatively large change of temperature difference is avoided, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the technical field of graphite electrodes, in particular to a graphite electrode for an electric arc furnace capable of preheating. Background technique [0002] Graphite electrode is a common conductor. Compared with metal electrodes, its production process is simpler. In electric arc furnaces, electric energy can be released in the form of arcs through the conductivity of graphite electrodes to heat and melt the furnace charge. However, when the existing graphite electrodes are used There are still some shortcomings: [0003] 1. The installation and fixing structure of the existing graphite electrode itself is relatively complicated. It is time-consuming and labor-intensive to install and disassemble the graphite electrode, and it is not convenient to adjust the height of the graphite electrode after installation, and it is not convenient to flexibly control its position , reducing the convenience of use of the device; [...
