[0016] Example 1: A production process for casting the air duct of a brake disc with a film-coated sand core method, according to the following steps: (1) Outsourcing film. The raw sand of the coated sand has a particle size of 50-100 mesh, a hot bending strength of 2.5MPa, a gas evolution of 14ml / g, a melting point of 103°C, and good collapsibility. (2) Install the electric core box on the core shooter, close the mold and take the coated sand into the electric core box quantitatively. The sand shooting time of the core shooter is 5 seconds, the electric heating curing temperature is 250 ℃, and the heating curing time is 50. Seconds, the coated sand is solidified in the electric heating core box to form a coated sand core, which is yellowish brown. (3) Take out the coated sand core from the electric heating core box, and set it up for use after trimming and inspection; (4) Put the coated sand core into the sand mold and pour, where the molten iron temperature is 1430℃, the spee...

[0018] Example 2: A production process for casting the air duct of a brake disc with a film-coated sand core method according to the following steps: (1) Outsourcing film. The raw sand of the coated sand has a particle size of 50-100 mesh, a hot bending strength of 2.5MPa, a gas evolution of 14ml / g, a melting point of 103°C, and good collapsibility. (2) Install the electric core box on the core shooter, close the mold and take the coated sand into the electric core box quantitatively. The sand shooting time of the core shooter is 8 seconds, the electric heating curing temperature is 280℃, and the heating curing time is 90 Seconds, the coated sand is solidified in the electric heating core box to form a coated sand core, which is yellowish brown. (3) Take out the coated sand core from the electric heating core box, trim and check for later use; (4) Put the coated sand core into the sand mold for pouring, where the molten iron temperature is 1450℃, the speed is 5 seconds, and the...
