| description | The invention discloses a preparation method of a needle coke reinforced pure carbon pantograph carbon slide plate, which comprises the following steps of: adding conductive carbon black, graphite powder, needle coke and pitch coke into a mixer for mixing by using needle coke with proper granularity as a reinforcing phase of the carbon slide plate, and adding the mixture and pitch into a double-screw kneading machine for kneading, thereby obtaining the needle coke reinforced pure carbon pantograph carbon slide plate. And carrying out hot rolling, extrusion, roasting and other processes to finally obtain the required material. The needle coke with proper granularity is used as a reinforcing phase of the carbon slide plate, and the quality of a final finished product is powerfully ensured by combining the needle coke with high strength and high conductivity with a carbon matrix; in addition, through cooperation of various particle sizes of the materials, the carbon slide plate finished product can obtain an exc |
