Automatic shot blasting machine is a commonly used surface treatment equipment, widely used in various industrial production fields. Its scope of use mainly includes the following aspects:

1. 金屬表面清理：自動式拋丸機可以用于清理金屬表面的氧化層、銹蝕、焊渣和污染物等，提高金屬材料的清潔度和質量，為后續的涂裝、噴涂或加工工藝提供良好的基礎。

1. Metal surface cleaning: Automatic shot blasting machines can be used to clean the oxide layer, rust, welding slag, and pollutants on the metal surface, improve the cleanliness and quality of metal materials, and provide a good foundation for subsequent painting, spraying, or processing processes.

2. 表面增強處理：通過拋丸技術，可以在材料表面形成一種細小的凹坑結構，提高表面的粗糙度和附著力，增強材料的疲勞強度、耐磨性和耐腐蝕性，適用于航空航天、汽車制造、橋梁建設等領域。

2. Surface reinforcement treatment: Through shot blasting technology, a small concave structure can be formed on the surface of the material, improving surface roughness and adhesion, enhancing the fatigue strength, wear resistance, and corrosion resistance of the material. It is suitable for fields such as aerospace, automotive manufacturing, and bridge construction.

3. 表面修復和翻新：自動式拋丸機可以用于修復磨損、受損或老化的金屬零部件表面，去除損傷層，恢復其原有的使用性能和外觀質量。

3. Surface repair and refurbishment: Automatic shot blasting machines can be used to repair worn, damaged, or aged metal component surfaces, remove damaged layers, and restore their original performance and appearance quality.

4. 壓力容器和管道清洗：拋丸清理可以有效去除壓力容器和管道內壁的油污、氧化皮、焊渣等雜質，保證容器和管道的安全可靠運行。

4. Pressure vessel and pipeline cleaning: Shot blasting cleaning can effectively remove impurities such as oil stains, oxide skin, welding slag, etc. from the inner walls of pressure vessels and pipelines, ensuring the safe and reliable operation of vessels and pipelines.

5. 鑄件除砂：自動式拋丸機廣泛應用于鑄造行業，可以去除鑄件表面的砂芯、砂眼以及其它殘留物，提高鑄件的質量和外觀。

5. Casting sand removal: Automatic shot blasting machines are widely used in the casting industry, which can remove sand cores, sand holes, and other residues on the surface of castings, improving the quality and appearance of castings.

總的來說，自動式拋丸機主要適用于金屬材料的表面清理、增強處理和修復，以及壓力容器、管道和鑄件的清洗和除砂等工藝需求。根據不同的應用場景和工作要求，還可以通過調整拋丸機的參數和工藝流程，實現定制化的表面處理效果。

Overall, automatic shot blasting machines are mainly suitable for surface cleaning, reinforcement treatment, and repair of metal materials, as well as cleaning and sand removal process requirements for pressure vessels, pipelines, and castings. According to different application scenarios and work requirements, customized surface treatment effects can also be achieved by adjusting the parameters and process flow of the shot blasting machine.
