Abstract (en)
[origin: WO2022064280A1] In order to extend the service life of electrode in the slag hole, a single copper electrode has been used in this invention. The special design of this part in resistance to thermal stresses makes it safe as a protective part against temperature of 1200 C. The heat generated in the body of this part is expelled from the part through the circulating fluid through the designed ducts and the temperature of the part remains constant to the extent that it does not cause damage to the part. The heat generated in the body of this part is expelled from the part through the circulating fluid through the designed ducts and the temperature of the part remains constant to the extent that it does not cause the destruction of the part.
