In the field of agricultural machinery, ductile iron is widely used. It is used to manufacture plowshares, harrow blades, and other tillage components, which need to withstand soil friction and impact during operation. The high strength and wear resistance of ductile iron allow it to adapt to harsh working environments, reduce wear, extend service life, and lower replacement frequency and maintenance costs. In harvesters, ductile iron is used to manufacture transmission gears, chains, and other transmission components, and its excellent mechanical properties ensure the stable and reliable operation of the transmission system, transmitting large torque and power, and adapting to frequent starts, stops, and speed changes during harvesting operations. In addition, structural components such as the frame and chassis of agricultural machinery also often use ductile iron, taking advantage of its high strength and good shock-absorbing performance to improve the overall stability and reliability of the machinery, reduce vibration and noise during operation, and provide a more comfortable working environment for operators.
