The production points of graphite electrode nipples have their own particularities. The thermal shock resistance of the nipples and the electrode body’s calcined product and the interface between the aggregate and the asphalt coke are different. In many areas, crack extension and extension easily occur in these areas during graphitization.
When producing ultra high power graphite electrode nipples, while considering the effect of “flatness” on nipple products, it is also necessary to realize that the interface between aggregate and asphalt coke is more widely distributed, and there are more weak areas. There are more potential structural defects between the focal interfaces and other factors.
The surface area of the uhp graphite electrode body is smaller than the nipple blank. The unit volume of the graphite electrode nipple blank is larger than that of the large-diameter electrode body blank. The nipple blank has a relatively large amount of heat dissipation. The temperature difference between the outer periphery of the nipple in series and the core is large. It is necessary to take technological measures to make up for the unfavorable factors such as the relatively large heat dissipation of the nipple blank and the large temperature difference between the periphery and the core.
For the production points of graphite electrode nipples, the conditions that each series of billets should meet are more stringent. To ensure the quality of the nipples, each series of columns must have the same temperature rise rate. The thermal insulation effect and the degree of heat loss of tandem columns in different spatial positions are different.
