Application and requirements of Marine forgings in ocean engineering

Marine engineering refers to the engineering technology field of utilizing Marine resources, developing Marine new energy and solving Marine space problems. Marine forgings, as an important part, are widely used in the construction of offshore platforms, the manufacture of ships and the development of Marine energy. Offshore platform: Offshore platform is the infrastructure of offshore engineering, including fixed and floating two types. Marine forgings play an important role in the construction of offshore platform, such as platform base, pile leg, cantilever beam and other key parts. These forgings not only need to withstand the weight of the platform, but also need to resist corrosion and shock in the Marine environment. Shipbuilding: Marine forgings also play an important role in shipbuilding,…

How to check the quality of Marine forgings?

As a key part, Marine forging plays an important role in shipbuilding, and its quality directly affects the safety and normal operation of the ship. Therefore, the quality inspection of Marine forgings is an important link in the process of shipbuilding. The following are some commonly used quality inspection methods: Appearance inspection: Appearance inspection is one of the most basic methods for quality inspection of Marine forgings. By observing the appearance of the forging, it can be found whether there are cracks, pores, inclusions and other defects on the surface of the forging. At the same time, the appearance inspection can also check whether the forging size meets the design requirements, and whether there are residual burrs. Non-destructive testing: Non-destructive…

What are the requirements for the material of Marine forgings?

Marine forgings, as the key parts, play an important role in ship manufacturing, and there are specific requirements for its material. In general, these requirements can include toughness, hardness, chemical composition, and so on. First of all, toughness is one of the important indicators of Marine forging material. Materials with good toughness can absorb more energy, are not easy to crack when impacted, and can better cope with various situations encountered during the operation of the ship. In general, Marine forgings require materials with excellent low temperature toughness, and can maintain good toughness between minus 50 degrees Celsius and minus 20 degrees Celsius. Secondly, hardness is also an important indicator of Marine forging material. Hardness determines the wear and corrosion…

What kinds of Marine forgings are there?

Marine forgings are an important part of ship manufacturing, which are used to manufacture hull, rudder, anchor chain and other key parts. According to different uses and manufacturing standards, Marine forgings can be divided into the following types: Hull forgings: Hull forgings are forgings used to manufacture hull structures, cabins and decks, including steel plates, sections, cast steel and other types. These forgings need to have high strength, toughness, wear resistance and corrosion resistance, as well as good processability and weldability. Rudder forgings: Rudder forgings are used to make the ship’s tail rudder and side rudder, usually made of high-strength steel, requiring high wear resistance and corrosion resistance. Anchor chain forgings: Anchor chain forgings are used to make anchor chains…

Construction machinery forging manufacturing need to pay attention to the problem

Construction machinery forging is an important part of machinery manufacturing, due to the particularity and complexity of its use, so in the manufacturing process need to pay attention to the following issues: Material selection problem Construction machinery forgings need to have a high strength, toughness and wear resistance and other comprehensive properties, but also consider the malleability of the material itself. Therefore, when choosing the right material for forging, it is necessary to consider the basic mechanical properties, microstructure, processing properties and economic factors of the material. In addition, attention should also be paid to the use of different materials to meet specific mechanical properties requirements. Forging technology The manufacture of construction machinery forgings needs to go through many process…

What are the classifications of construction machinery forgings?

Construction machinery forging is a kind of mechanical parts made by forging process, which is widely used in various construction machinery. According to different classification methods, construction machinery forgings can be divided into different types. Structural parts Structural parts are forgings that constitute the main structure of construction machinery, such as excavator buckets, loader crab claws, crane boom, etc. These forgings play an important role in bearing load, transmitting force and movement in construction machinery, so their strength, stiffness and stability are required to be high. Accessories Accessories are forgings used in construction machinery attachment systems, such as excavator bucket teeth, loader rims, crane pulleys, etc. These forgings have an important impact on the working efficiency and working quality of…

Process characteristics and application of construction machinery forgings

As a key component, construction machinery forgings play a vital role in mechanical equipment. They are not only under great pressure, but also need to work stably in a variety of complex environments, so the performance requirements for their strength, wear resistance, fatigue resistance and reliability are very strict. This paper will introduce the process characteristics and application of construction machinery forgings. First, process characteristics Heating link Forging heating is a process to improve the plasticity of metal materials, through heating the metal material to reach the temperature of plastic deformation, in order to carry out pressure processing. Construction machinery forgings are usually heated by electric furnaces, gas furnaces or reflector furnaces, and the heating temperature depends on the type…
