Impregnated bitumen refers to the bitumen used to impregnate carbon products. Magnesia-carbon brick manufacturers reduce the porosity of products and increase the bulk density or achieve the purpose of impermeability. Carbon products are generally impregnated with coal pitch, and petroleum pitch or synthetic resin are also used. With the enlargement of electric furnaces and the development of refining technology outside the furnace, the demand for high-power and ultra-high-power electrodes is increasing, and the quality requirements are becoming higher and higher. To improve the quality of electrodes and electrode joints and reduce the unit consumption index of the electrodes, the key is to increase the bulk density and strength of the electrodes and electrode joints. Therefore, it is necessary to carry out in-depth research and selection of the new impregnating agent used in the impregnation process, impregnated asphalt. In order to cooperate with the development of domestic impregnated asphalt, the index values of impregnated asphalt and Shanghai asphalt in each process are compared to obtain The development of bitumen makes useful suggestions. At the same time, electrode manufacturers can also make favorable choices for the reasonable use of impregnated asphalt.
