Currently, the ring rolling mill in China is imported from Elite, which can have a diameter of 16 meters and a height of 3 meters. Various large disk, ring, and cylindrical forgings, with a unit weight of 200 tons, a radial rolling force of 2500 tons, and an axial rolling force of 1250 tons. It is the world's radial and axial ring rolling equipment.
Class common use: connecting various segmented cylindrical equipment.
The following three pictures show the role of the large ring in wind power generation. Among them, one is the foundation pile flange manufactured by Siemens 7MW offshore wind turbine; The second is the foundation pile part of the same type in Europe; The third is the renderings of the assembled Siemens 7MW giant wind turbine.
Siemens 7MW foundation pile flange.
Note that not only does the wind turbine tower need to be connected to a large ring, but many cylindrical devices use it. For example, the following large equipment, typically hundreds of millions and billions, is also connected through large ring forgings and arrows.
The second type commonly used: transmission devices.
First of all, let's take an image point. This is a 10m level slewing bearing made by the world's bearing manufacturer LIEBHERR. It has grown like this!
The following large devices use it.
The pressure vessel barrel is the third common use.
It's not important to not know what pressure vessels are. The important thing is that you just know that they are really pressure resistant.
It is the most nuclear thing in a nuclear power plant, called a reactor pressure vessel. It is said to be the most nuclear. First, it is located in the center of the nuclear power plant. Secondly, because it is the place where the nuclear reaction takes place and the fuel rods are installed in its stomach, this guy cannot afford it. It is not such a cruel role in nuclear power plants, such as evaporators, pressurizers, etc.
In fact, not only nuclear power, but also various chemical products that we cannot live without now are obtained through different chemical reactions in the stomachs of different forms of pressure vessels.
