The invention relates to a mold 
casting method for a hollow axle steel of a high-speed 
passenger train. The method comprises the following sequential steps of: I, setting the temperature of 
ingot molds to be 30-80 DEG C before 
casting; II, 
casting 2-3 discs for each furnace, preparing 4-6 
ingot molds of which capacity is 5.8-8.4 tons, pumping inside of the mold to be clean before casting, purging the 
ingot molds with 
argon, and adding 12-16Kg of casting 
powder for each ingot mold; III, setting 
molten steel superheat degree before casting process to be 35-55 DEG C; IV, before the casting process, adding a cover for the steel 
ladle, covering a cap opening with an iron sheet, opening the steel 
ladle, discharging 1.0-1.5t of steel, after putting the steel 
stream in order, adding a central casting 
pipe for casting, carrying out 
argon sealing protection during the 
steel casting process, setting the 
ingot casting speed to be 125-165mm / min, setting the cap opening casting speed to be 35-65mm / min, when casting 1 / 2-2 / 3 of the cap opening, carrying out 
trickle filling, and adding 9-12Kg of heat generating agent for each ingot mold when casting to 2 / 3 height of the cap opening; and V, setting the time from the end of casting to demolding of the steel ingot to be not less than 4.5 hours. With the steel ingot formed by mold casting method provided by the invention, the general looseness and the central looseness of the macrostructure of the axle billet cogged by the blooming mill are not more than 0.5 level, and the pattern segregation is 0.
