[0002] Coated sand is molding sand or core sand whose surface is covered with a layer of solid resin film before molding. There are two coating processes: cold method and hot method. The cold method is to dissolve the resin with ethanol and add urotropine during the sand mixing process so that the two are coated on the surface of the sand grains. The ethanol evaporates to obtain coated sand; the hot method is to preheat the sand to a certain temperature, add resin to melt it, stir it to coat the resin on the surface of the sand grains, add urotropine aqueous solution and lubricant, cool, crush and sieve to obtain coated sand, which is used for casting steel and iron parts.
