As the key parts of Marine rudder system, heat insulation and high temperature protection technology are very important to its stability and safety when operating in high temperature environment. This paper will discuss the heat insulation and high temperature protection technology of Marine rudder system forgings, aiming to provide reference for its performance improvement in practical application.
Thermal insulation property
Material selection: The material selection of Marine rudder forgings has an important impact on its thermal insulation performance. Materials with good heat resistance can withstand higher temperatures and effectively reduce heat transfer, thus improving thermal insulation performance. For example, the selection of heat-resistant steel, nickel-based alloys and other materials, these materials have good high temperature stability and creep resistance, can meet the requirements of high temperature environment.
Thermal insulation structure design: Reasonable thermal insulation structure design can effectively reduce the heat conduction and heat radiation of Marine rudder forging. By setting the structure of heat insulation layer and thermal insulation layer on the surface of the forging, the heat transfer to the inside of the forging can be reduced, the temperature gradient can be reduced, and the heat insulation performance can be improved. At the same time, the impact of structural design on weight, strength and safety should be considered to ensure that the thermal insulation structure can meet the actual operation needs.
Application of thermal insulation materials: Coating of thermal insulation materials on the surface of Marine rudder forging is an effective way to improve thermal insulation performance. Common thermal insulation materials include ceramic thermal insulation coating, high temperature resistant tape and so on. These materials have low thermal conductivity and high temperature resistance, which can block the transfer of heat and reduce the surface temperature.
High temperature protection technology
High temperature protective coating: Coating the surface of Marine rudder system forgings with high temperature protective coating can provide effective protection against high temperature oxidation and corrosion. Commonly used high temperature protective coatings include aluminide coatings, ceramic coatings and so on. These coatings have a high melting point and chemical stability, which can maintain stable performance at high temperatures and effectively prevent oxidation and corrosion.
Cooling technology: In order to prevent the forging of Marine rudder system from overheating and deformation in a high temperature environment, appropriate cooling technology can be used. For example, by setting a cooling channel inside the forgings and passing coolant for circulation cooling, the forging temperature can be effectively reduced to prevent overheating and deformation. At the same time, local cooling technology, such as water spray cooling, can also be used for high temperature areas to enhance the protection against high temperatures.
High temperature monitoring and early warning system: The establishment of high temperature monitoring and early warning system can carry out real-time monitoring and early warning of the operating status of Marine rudder system forgings. By setting the temperature sensor at the key part, real-time monitoring of temperature changes, once the abnormal temperature is found to rise or exceed the safety threshold, the system will immediately issue an alarm and take appropriate protective measures to ensure the safe operation of the forging.
The heat insulation performance and high temperature protection technology of Marine rudder forging are of great significance for ensuring the safety, stability and prolonging the service life of the ship. Through reasonable selection of materials with good heat resistance, optimization of thermal insulation structure design, application of thermal insulation materials and high temperature protective coatings, as well as appropriate cooling technology and high temperature monitoring and warning system, the heat insulation performance and high temperature protection ability of Marine rudder system forgings can be effectively improved. This helps to reduce the impact of heat on forgings, prevent overheating and deformation, and extend service life. In the future development, enterprises should strengthen technological innovation and research and development efforts, and constantly improve the manufacturing technology and surface treatment level of Marine rudder forgings, in order to meet market demand and promote the sustainable development of the Marine industry.
