[0002] Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex stresses and high requirements for strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "iron instead of steel" mainly refers to ductile iron. According to the authorization announcement number CN219816716U, a rust-proof treatment device for ductile iron parts is disclosed, including a base, a frame is provided at the upper end of the base, a spraying device is provided at the top of the frame, through grooves are opened on the side walls on both sides of the frame, rotating plates are rotatably connected in the two through grooves, rotating rods are penetrated and rotatably connected on the two rotating plates, the two rotating rods are located inside and outside the frame, connecting rings are provided, and the two connecting rings are on the opposite side walls A plurality of circumferentially arranged fixing rods are provided, and the ends of the plurality of fixing rods on the same side are fixedly connected with clamping plates, and the outer walls of the two rotating rods are provided with connecting mechanisms for connecting the connecting rings.
