Forged parts for shipbuilding
Forged parts for shipbuilding are mainly used in the power system, transmission system and structural system of ships. Luoyang Forging uses die forging to provide customers with forged parts for ships.
Application of forged parts for shipbuilding
1 The power system of a ship should be. The core components of a ship diesel engine are crankshafts, connecting rods, cylinder heads, etc. The piston moves up and down repeatedly in the cylinder and is connected to the crankshaft through a connecting rod. The crankshaft directly converts this rotational motion into linear motion, and then drives the wheel and gearbox, and finally transmits power to the wheel or propeller.
2 Forged parts for the transmission system of a ship Propeller shaft, gearbox components, these two forged parts are generally required to be forged with titanium alloy.
3 Hull forged parts Rudder stock, anchor chain accessories. The rudder stock controls the direction and speed of movement of the ship.
Material selection for forged parts for shipbuilding
Forged parts for shipbuilding are generally required to be corrosion-resistant and high-strength. The material selection mainly includes the following types
1 Carbon steel
AISI 1045 / 45# steel, AISI 4140 / 42CrMo, etc. Mainly forged for crankshafts, connecting rods, etc., and high strength performance will be obtained through heat treatment in the later stage.
2 Stainless steel
304 / 316 stainless steel, UNS S32205 can be used in the propulsion system of ships or the pipeline connection of ships.
3 Titanium alloy
Titanium alloy is a corrosion-resistant material that can be used in corrosion-resistant forged parts of ships, such as propellers, anchor handles, chain links, etc.
Why choose forged ship parts
Shipping is a complex job, mainly working at sea, facing seawater and seawater erosion every day,
Forged ship parts can improve the corrosion resistance, strength and toughness of ship parts. Forged ship parts can improve the performance of forged parts as a whole. For example, the crankshaft is forged and heat treated to improve strength and corrosion resistance. The mooring chain link is made of AISI 4140 through hot die forging + shot peening to improve toughness.
