② Adjustment of molding sand particle size: adjust according to the median value of 50/100 sieve (silica sand of 50/100 sieve, the median value of the average fineness is 50 [4]), when the AFS of the molding sand is less than or equal to 50, by adding fine sand 70/140 or finer new sand 140/70 is adjusted, 30kg-60kg is added per mill, and the change in particle size is analyzed.
