Due to the characteristics of steel castings, almost all industrial departments need steel castings, which are widely used 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. As for the application of steel castings in various industrial sectors, there may be great differences due to different specific conditions in various countries.
There are many kinds of steel castings. The use of steel castings in several major industrial sectors is briefly described.
1.Power station equipment
Power station equipment is a high-tech product, and its main parts operate continuously for a long time under high load. Many parts of thermal power station and nuclear power station equipment need to withstand the corrosion of high temperature and high pressure steam, so there are strict requirements for the reliability of parts. Steel castings can meet these requirements to the greatest extent and are widely used in power station equipment.
2.Railway locomotive and rolling stock
Railway transportation is closely related to the safety of people’s lives and property. It is very important to ensure safety. Some key components of locomotive and vehicle, such as wheel, side frame, bolster, coupler, etc., are traditional steel castings.
The turnout used for railway switch is a component that bears strong impact and friction. The working conditions are very bad and the shape is very complex.
3.Construction, construction machinery and other vehicles
The working conditions of construction machinery and engineering machinery are very poor. Most parts bear high load or need to withstand impact wear. A large part of them are steel castings, such as driving wheel, bearing wheel, rocker arm, track shoe, etc. in the action system.
Steel castings are rarely used in general automobiles, but many steel castings are also used in the operation part of special off-road vehicles and heavy trucks.
