Problems solved by technology

[0004] However, the existing carbon slider preparation method is generally to mix and knead pitch coke and pitch at a certain temperature, extrude the molded product for one-time roasting, then impregnate the pitch, and then perform a second roasting. Carbon sliders have some defects such as time-consuming and labor-intensive, increased cost, low production efficiency,

Abstract

The invention discloses a preparation method of a pantograph carbon slider, comprising the following steps: S1, grinding petroleum coke, pitch coke and modified asphalt into powder; S2, grinding the ground petroleum coke powder, pitch coke powder and The modified asphalt powder is mixed and kneaded into paste; S3, the kneaded paste is rolled out on the flake mill after it is out of the pot; S4, the rolled flakes are milled; S5, the milled powder is put into the pressing machine for heating Pressing; S6, the pressed molded product is roasted; S7, cooling is released, and the pantograph carbon slider is formed. The preparation method can manufacture a high-performance pantograph carbon slider, and the material procurement is easy, the dipping process is saved, and the beneficial effects of simple production operation, time saving, efficiency improvement, cost reduction and economic benefit improvement are achieved.

Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to a method for preparing a pantograph carbon slider. Background technique [0002] With the continuous development of railways, high-speed trains are also growing. Among them, electric traction high-speed trains use the pantograph carbon slide system to continuously rub against the catenary wires to guide the current on the grid and transmit it to the locomotive. The power system is used to maintain the normal operation of the electric locomotive. Therefore, the pantograph slide is an important current-collecting component for electric locomotives to obtain power. The pantograph carbon slide is an electrical contact material that integrates high conductivity, wear resistance and friction reduction. Therefore, the relationship between the pantograph slide plate made of this material and the catenary wire constitutes a special friction of mechanical and electrical coupl...
