There are conflicting opinions on the selection of kneading temperature of electrode paste and anode paste. In the electrode paste th14-14. Production of a 08-84 In the process specification, the proposed kneading temperature is 120-140 ℃, the temperature given in document  is 160-170 ℃, and the temperature given in document [2,3] is 120-140cc, which is 50-70oc higher than the softening point of asphalt, i.e. medium temperature asphalt (foctzzoo-541 impact No. a).
When determining the kneading temperature of the mixture, first of all, it is necessary to consider the wetting start temperature of the asphalt to the granular material. For the medium flow asphalt with grade A, the wetting start temperature of the coke is 124 ℃, and the wetting start temperature of the calcined anthracite is i15cc. Therefore, the kneading temperature of the ingredients is 125-130 ℃.
Increasing the kneading temperature can make the asphalt evenly distributed among the filler particles and make the paste dense. However, too high the heating temperature can also cause the binder to oxidize and then lose the cohesiveness. Document  shows that in the gas of superheated asphalt, there is a group of cx-n = O, = CX 2O, which will make the polycondensation worse and form a loose structure during the coking of asphalt.
