Steel shot is a metal material widely used in industry and construction, mainly used for polishing, grinding, rust removal, paint removal and cleaning of surface treatment. It is usually made of materials such as cast iron, steel, etc., and undergoes processes such as crushing, grinding, and screening to finally form particles of different sizes and shapes. For non-professionals, they may not know much about the characteristics and selection methods of steel shots. This article will introduce the characteristics of steel shot in detail, and how to choose a high-quality steel shot.
First, the characteristics of steel shots.
1.High strength: The steel shot is smelted at high temperature and cooled at high speed during the manufacturing process, which gives it extremely high strength and hardness, and can withstand high loads and high impacts.
2.Good wear resistance: The surface of the steel shot has been specially treated to make it have good wear resistance and can maintain a long-term service life in various complex environments.
3.Easy to process: Steel shot can be processed by various machining methods, such as cutting, drilling, tapping, etc., which is convenient for users to customize according to their needs.
When choosing a steel shot, there are several factors to consider:
1.Material: The material of the steel shot determines its hardness and wear resistance. Generally speaking, cast iron steel shot is relatively soft and suitable for occasions with low surface requirements; Carbon steel shots, on the other hand, are harder and are suitable for occasions that require a higher surface finish.
2.Granularity: Granularity refers to the diameter of the steel shot. Different particle sizes are available for different surface treatment needs. In general, smaller particle sizes can achieve finer surface finishes, but require more processing time and effort.
3.Purity: Purity refers to the amount of impurities in the steel shot. Steel shots with high purity can get better surface treatment results, because impurities will affect the hardness and wear resistance of steel shots.
4.Shape: Steel shots come in a variety of shapes, such as spherical, oval, cube, etc. Different shapes of steel shots are suitable for different application scenarios. For example, spherical steel shots are suitable for polishing and grinding, while cubic steel shots are suitable for cleaning nooks and crannies.
When choosing a steel shot, you need to consider the above factors according to the specific application. For example, if you need to polish the metal surface, you can choose a carbon steel shot with a smaller particle size; If you need to clean up rust and paint, you can choose spherical cast iron steel shots. In addition, the method of use and storage conditions are also matters that need to be noted. The correct use method can ensure that the performance of the steel shot is fully exerted, and the good storage conditions can ensure that the performance and use effect of the steel shot are not affected. Therefore, when using and storing steel shots, the relevant precautions and regulations should be followed.
