Processing and surface treatment methods of reinforced steel shot

　　Reinforced steel shot is a material widely used in the surface treatment industry, mainly used for shot peening, shot blasting, casting sand cleaning and other processes. The processing and surface treatment methods of reinforced steel shot are crucial to ensure its performance and service life. The following will introduce the processing and surface treatment methods of reinforced steel shot in detail.

　　1. Processing methods of reinforced steel shot

　　1. Melting: First, select suitable raw materials, generally high carbon steel or alloy steel, and melt them through medium frequency electric furnace or other smelting equipment to obtain pure molten steel.

　　2. Casting: Inject the molten steel into a special mold for steel shot, and form a steel shot blank after cooling and solidification.

　　3. Primary processing: Crushing the cast steel shot blank, removing excess parts such as pouring and riser, and then performing preliminary shaping.

　　4. Heat treatment: Quenching and tempering the steel shot after primary processing to improve its hardness and toughness to form reinforced steel shot.

　　5. Surface treatment: Polish and grind the reinforced steel shot to remove surface defects and improve surface smoothness.

　　6. Detection and sorting: Remove unqualified steel shots through magnetic separation, screening and other methods to ensure product quality.

　　2. Surface treatment methods for reinforced steel shots

　　1. Cleaning: Use organic solvents or alkaline solutions to clean the steel shots to remove grease, dirt, etc. on the surface.

　　2. Shot blasting: Use the high-speed rotating blades of the shot blasting machine to project the steel shots onto the surface of the workpiece to achieve the purpose of strengthening or cleaning.

　　3. Heat treatment: Appropriate heat treatment of the steel shot can improve its surface structure and improve its wear resistance.

　　4. Coating: Apply a special coating, such as ceramic coating or metal coating, to the surface of the steel shot to improve its corrosion resistance and high temperature performance.

　　5. Plating: Deposit a layer of metal, such as chrome plating, nickel plating, etc., on the surface of the steel shot by electroplating or chemical plating to enhance its surface properties.

　　6. Precision grinding: Use precision grinding equipment and abrasives to finely process the steel shot to obtain higher dimensional accuracy and surface finish.

　　The processing and surface treatment methods of reinforced steel shot include smelting, casting, primary processing, heat treatment, surface treatment, and detection and sorting. These processing processes not only determine the performance and quality of the steel shot, but also have an important impact on its service life and application effect. Therefore, strictly controlling the operation and process parameters of each step is the key to manufacturing high-quality reinforced steel shot. Processing and surface treatment methods of steel shot
