Learn the Optimal Temperature and Melting Point of Pitch During the Graphite Electrode Impregnation Process?
Impregnation is a process of reducing the pores of graphite electrodes, increasing the density, increasing the compressive strength, reducing the resistivity of the finished product, and changing the physical and chemical properties of the product. Maintaining a good rheological state of the impregnating asphalt during the impregnation process is the key to improving the impregnation […]
