The invention discloses an
electric locomotive pantograph copper-impregnated carbon contact strip producing method. The method comprises the steps that 1,
pitch coke powder,
graphite powder, siliconized
graphite powder and high temperature
pitch are mixed according to the proportion to be ground into powder; the mixed powder is prepressed into a stage stock column, and then the stage stock column is solidified and squeezed to be molded and roasted, so that a composite carbon contact strip is obtained; 2, the composite carbon contact strip is cleaned and dried, then is cooled and placed into a
graphite crucible, and is placed in an electric furnace at temperature of 1300-1400 DEG C to be preheated;
copper liquid is poured into the
crucible to soak the composite carbon contact strip, then the
crucible is placed in an oil press cover,
nitrogen is led in, heat preservation is kept for 3-5 min under the specific intensity of pressure, and finally cooling is carried after pressure releasing. According to the
electric locomotive pantograph copper-impregnated carbon contact strip producing method, the electroconductibility of the copper-impregnated carbon contact strip is improved, the electrical resistivity is lowered, the
mechanical strength of the carbon contact strip and copper impregnated angle can be increased, then the carbon contact strip
abrasive resistance and self-
lubrication are improved, the copper-impregnated carbon contact strip is more resistant to abrasion, main line damage and block dropping are avoided, the
shock resistance is high, and the service life of the copper-impregnated carbon contact strip is prolonged.
