Ductile Iron Casting Part Series 5
JHshukong
Application of ductile iron in ships：
I. Application in ship structures
1. Load-bearing structure
The main function of ductile iron in ship structures is to serve as a load-bearing structure. When bearing the huge pressure and tension on the bottom and sides of the hull, the high strength and rigidity of ductile iron can ensure the stability and torsion resistance of the hull, thereby ensuring the safety of the hull.
2. Buffer material
Ductile iron is also widely used in ship buffer materials, which can reduce the impact and vibration caused by the collision between the ship and the dock, other ships or cranes, thereby reducing the stress condition of the hull and avoiding damage to the hull.
3. Anchoring equipment
The main function of ductile iron in anchoring equipment is to bear the tension of the anchor chain and anchor. The high strength and corrosion resistance of ductile iron can ensure the reliability and durability of the anchoring equipment.
II. Application in ship machinery and accessories
1. Engine base
The main function of ductile iron in the ship engine base is to bear the weight and vibration of the engine. While ensuring the stability of the hull, it can reduce the vibration and noise of the engine and improve the safety and comfort of navigation.
2. Water pumps, valves and pipe fittings
The main role of ductile iron in ship water pumps, valves and pipe fittings is to withstand the pressure and corrosion of liquids. The high corrosion resistance and high wear resistance of ductile iron can ensure the long life and watertightness of these fittings, thereby ensuring the safety and stability of the hull.
3. Nozzles and propeller blades
Ductile iron is also widely used in ship nozzles and propeller blades. Its high wear resistance can reduce friction loss, improve the efficiency and energy saving effect of the propeller, thereby reducing the operating cost of the ship.
