Due to the characteristics of steel castings, almost all industrial sectors need to use steel castings, in ships and vehicles, construction machinery, engineering machinery, power station equipment, mining machinery and metallurgical equipment, aviation and aerospace equipment, oil wells and chemical equipment, etc. The application is particularly extensive. As for the application of steel castings in various industrial sectors, due to the different specific conditions of each country, the situation may be quite different.
There are many varieties of steel castings, too numerous to enumerate. Here is a brief description of the use of steel castings in several major industrial sectors.
1. Power station equipment
Power plant equipment is a high-tech product, and its main parts operate continuously for a long time under high load. Many parts in thermal power plant and nuclear power plant equipment still need to withstand the corrosion of high temperature and high pressure steam, so the reliability of the parts is greatly affected. There are very strict requirements. Steel castings can meet these requirements to the greatest extent and are widely used in power station equipment.
2. Railway locomotives and vehicles
Railway transportation is closely related to the safety of people's lives and property, therefore. Ensuring safety is paramount, and some key components of rolling stock, such as wheels, side frames, bolsters, couplers, etc., are traditional steel castings.
The turnout used for railway switch is a component that bears strong impact and friction, the working condition is extremely harsh, and the shape is very complicated.
3. Construction, engineering machinery and other vehicles
The working conditions of construction machinery and engineering machinery are very poor. Most of the parts are subjected to high loads or need to withstand impact wear, and a large part of them are steel castings, such as driving wheels, load wheels, and rocker arms in the mobile system. , track shoes, etc.
Steel castings are rarely used in general cars, but a lot of steel castings are also used in the action parts of special off-road vehicles and heavy trucks.
