Method for manufacturing bottom blowing type cast train wheel graphite mold
The invention relates to the field of graphite materials, and in particular relates toa method for manufacturing a bottom blowing type cast train wheel graphite mold. The method comprises the following steps: crushing, screening, blending and mixing calcined coke, adding medium-temperature asphalt, and performing wet mixing, molding, primary roasting, dipping, secondary roasting and graphitization, thereby obtaining a finished product, wherein the conditions for adding medium-temperature asphalt for wet mixing are as follows: vacuuming the medium-temperature asphalt while heating, and stirring for 10-40 minutes when the heating temperature is 180-210 DEG C and the vacuum degree is 500-5000pa. The graphite material provided by the invention is moderate in porosity, small in size of pores, uniform in crystal particle, low in ash content, relatively small in thermal expansion coefficient, excellent in mechanical property and antioxidant property, and is a very excellent graphite material for manufacturing bottom blowing type cast train wheel graphite molds.
