[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron. Steel castings are widely used in various industries due to their excellent performance and have become an indispensable and important component of various machines. Cast steel refers to steel materials specially used to manufacture steel castings. When the strength requirements of castings are high and cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of molten steel of cast steel is not as good as that of cast iron. Therefore, the thickness of the casting structure cannot be too small, and the shape should not be too complicated. When the silicon content is controlled at the upper limit, the fluidity of molten steel can be improved. Cast steel can be divided into general engineering cast steel, welded structure cast steel, stainless steel cast steel, and heat-resistant steel cast steel according to its variety and use. In the production and processing of steel castings, grinding equipment will be used to grind and remove burrs or excess materials around the steel castings to improve the overall smoothness of the surface of the steel castings and ensure that the size and shape meet the production standards.
