Embodiment Construction

[0022] Below in conjunction with embodiment the present invention is further described.

[0023] A preparation method of a pantograph carbon slide plate, comprising the steps of:

[0024] S1. Put petroleum coke powder, asphalt coke powder, sulfur, coke powder, and carbon fiber as powdered raw materials in a mixer according to the required ratio for mixing, so that all kinds of dry powder are mixed evenly. When mixing to half, add silicon powder and copper powder, during the mixing process, the agitator is in a closed state, and the powdery raw materials are proportioned according to parts by weight: 35-40 parts of petroleum coke powder, 30 parts of pitch coke powder, 1-1.5 parts of sulfur, 2.5 parts of coke Powder, 10 parts of carbon fiber, 3-6 parts of silicon powder, 1.8-2.4 parts of copper powder, 32-38 parts of medium temperature asphalt, the powder used is 60 mesh, the particle size of silicon powder is 800 mesh; the steps of adding copper powder and silicon powder It is...

Abstract

The invention discloses a preparation method for a carbon contact strip of a pantograph. The preparation method comprises the following steps: placing powdery raw materials into a mixer according to arequired ratio, and carrying out stirring to uniformly mix all the dry powders; after all the dry powders are mixed, carrying out standing until suspended powders are settled, adding melted medium-temperature asphalt into the mixed dry powders, and continuing stirring so as to prepare a mixed and kneaded material; conveying the mixed and kneaded material into a mold, carrying out hot pressing inthe conveying process at the same time, and preparing an initial carbon contact strip blank from the mixed and kneaded material in the mold; conveying the initial carbon contact strip blank into a calcination furnace, starting a heating device, and carrying out calcination treatment so as to obtain a sintered initial carbon contact strip blank; and successively subjecting the sintered initial carbon contact strip blank to impregnation and drying treatment so as to obtain the finished carbon contact strip. The method provided by the invention can increase decontamination effect to a certain extent, and reduces processing cost at the same time.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a method for preparing a pantograph carbon slide. Background technique [0002] With the development of my country's high-speed rail business, the development and improvement of pantograph carbon skateboards has also become one of the key research and development objects. The pantograph slide is the most important current-collecting component in the locomotive power supply system. It is installed on the pantograph and directly contacts the catenary wire, which belongs to the category of sliding contact contact materials. Through the contact between the pantograph slide plate and the transmission line, the current on the transmission network is guided down and transmitted to the locomotive power supply system to maintain the normal operation of the electric locomotive. There are three main types of pantograph slides: powder metallurgy slides, carbon slides, and met...
