The ductile iron castings roll during the movement, which makes it easier to contact with the rust inhibitor. The rust inhibitor is discharged to the drain pipe 7 through the water pump 6. The rust inhibitor is sprayed out through the nozzle 8 and contacts with the ductile iron castings, which can prevent the ductile iron castings from rusting. At the same time, less rust inhibitor is more convenient for subsequent air drying. Fresh air is inhaled through the fan 11, and the fresh air is heated by the heating box 13 and then discharged, which can increase the air drying efficiency of the rust inhibitor. The excess rust inhibitor can be drained out through the through holes to reduce the rust inhibitor remaining on the surface of the ductile iron casting.
