Abstract

The invention discloses a carbon sliding block used for a maglev train. The carbon sliding block comprises an aluminum support and a carbon sliding block composite material which is connected with thealuminum support, and the carbon sliding block composite material is prepared by the following methods: under a heating condition, mixing all raw materials of the carbon sliding block material uniformly to obtain a mixed material; performing pressing on the mixed material, performing curing, and performing extrusion molding treatment to obtain a molded blank; performing roasting treatment on theblank to obtain a carbon sliding block material; under a heating condition, performing melting and uniform mixing on impregnating metal raw materials to obtain an impregnating metal liquid; and pouring the impregnating metal liquid onto the heated carbon sliding block material, and pressing the impregnating metal liquid into the carbon sliding block material through air pressurization to obtain the carbon sliding block composite material. The carbon sliding block provided by the invention has the advantages of good wear resistance, pressure resistance and strength, good stability, high environmental adaptability, good processing performance, good conductivity and heat conducting performance, long service life, and good physical, mechanical and chemical properties.

Description

technical field [0001] The invention relates to a carbon slider for the third rail of a maglev train, in particular to a carbon slider for a maglev train, which belongs to the field of urban rail transit accessories. Background technique [0002] The maglev train is a modern high-tech rail vehicle, which realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the linear electromagnetic force to pull the train to run. With the continuous enhancement of the country's economic strength and the improvement of people's living standards, it is necessary to improve the transportation capacity of rail transit to meet the needs of economic development and people's livelihood. Germany, Japan, the United States and other countries have launched the development and research of maglev trains. Germany and Japan went to achieved relatively large achievements. At present, my country has opened maglev trains in Shanghai, ...
