Method for preparing pantograph slide plate composite carbon core of electric locomotive (including high-speed train) by using cold isostatic pressing process
The invention relates to a method for preparing a pantograph slide plate composite carbon core of an electric locomotive (including a high-speed train) by using a cold isostatic pressing process. The method uses various carbon materials for producing a pantograph slide plate carbon core material by a certain formula, or uses a carbon material and branch-shaped nickel powder or copper powder for burdening by a certain formula requirement to prepare the pantograph slide plate composite carbon core; the process comprises the following steps: the ingredients are treated by using a grinding process or a planetary mixing process; a mold sleeve is produced by requirements of a cold isostatic press; then, the materials are evenly added through a vibrator into the mold sleeve; the mold sleeve is put in the cold isostatic press; the compression molding is finished by the cold isostatic press to prepare a composite carbon core blank; and the blank is roasted and dipped to prepared a high-performance pantograph slide plate carbon core composite material of the electric locomotive. The carbon core has the advantages of good electric conductivity, heat resistance, electric arc resistance, high mechanical strength, good lubricating performance and wearing resistance, low production cost and easy realization of industrialization.
