What are the production processes of reinforced steel shots?

　　1. Raw material preparation

　　The raw materials for reinforced steel shots are generally high-quality steel wire or scrap steel. These raw materials need to be strictly selected and tested to ensure that their chemical composition and physical properties meet the production requirements. In particular, the content of elements such as silicon, manganese, carbon, and the limit of harmful elements such as sulfur and phosphorus need to be strictly controlled within a certain range.

　　2. Melting and granulation

　　Melt: The selected raw materials are put into the smelting furnace for smelting. The furnace temperature and smelting time need to be controlled during the smelting process to ensure that the composition of the molten steel is uniform and meets the standards.

　　Granulation: The smelted molten steel is granulated by a specific granulation equipment (such as a centrifugal granulator). In this step, the molten steel is quickly thrown into a cooling medium (such as water) to form a pill. The use of the centrifugal method can ensure that the size and shape of the pill are relatively uniform.

　　3. Heat treatment

　　The granulated steel shot needs to be heat treated to improve its hardness and wear resistance. Heat treatment generally includes three processes: heating, insulation and cooling. By controlling parameters such as heating temperature, holding time and cooling rate, reinforced steel shots with different hardness and functions can be obtained.

　　4. Selection and grading

　　The steel shots after heat treatment need to be graded by the selection equipment to ensure that their particle size meets the application requirements. During the selection process, steel shots of different particle sizes will be separated for subsequent use and storage.

　　5. Strengthening treatment

　　In order to further improve the strength and durability of the steel shots, strengthening treatment is also required. This step generally includes shot peening or other similar processes, which use high-speed spraying of steel shots to impact the surface of the workpiece to form a compressive stress layer, thereby improving the fatigue resistance and corrosion resistance of the workpiece.

　　6. Quality inspection and packaging

　　Finally, the quality of the reinforced steel shots produced is inspected, including hardness testing, particle size testing, etc., to ensure that their quality meets the standards. Qualified steel shots will be packaged and stored, waiting for sale and use.
