  • 抛丸机的应用在什么地方?

表面清理
抛丸设备首先应用于铸造业铸钢、铸铁件的表面粘砂及氧化皮的清除。
几乎所有的铸钢件、灰铸件、 玛钢件、球铁件等都要进行抛丸处理。这不仅是为了清除铸件表面氧化皮和粘砂,同时也是铸件质量检查前不可缺少的准备工序, 比如大型气轮机机壳在进行无损探伤以前必须进行严格的抛喷丸清理,以保证探伤结果的可靠性。在一般铸件生产中,抛喷丸清理是发现铸件表面缺陷如皮下气孔、渣孔以及粘砂、冷隔、起皮等的必不可少的工艺手段。有色金属铸件,如铝合金、铜合金等的表面清理,除清除氧化皮、发现铸件的表面缺陷外,更主要的目的是以抛喷丸来清除压铸件的毛刺和获得具有装潢意义的表面质量,获得综合效果。冶金钢铁生产中,抛喷丸或者酸洗是保证钢铁大量生产中获得高生产率而采用的机械或化学联合去除磷皮的一种工艺方法。硅钢片、不锈钢薄板等其他合金钢板、带的生产中,在冷轧工序过程中必须进行退火后再进行抛丸或酸洗处理,以保证冷轧钢板的表面粗糙度及厚度精度。
工件强化
根据现代金属强度理论,增加金属内部的错位密度,是提高金属强度的主要方向。实践证明抛丸是增加金属位错结构的行之有效的工艺方法。这对一些金属不能通过相变硬化或实现相变硬化的基础上而要求再进一步强化的工件而言,更具有十分重要的意义。航空、宇航工业、汽车、拖拉机等零部件要求轻质化,但可靠性要求越来越高,其重要工艺措施就是采用抛喷丸工艺提高构件的强度和疲劳强度。



Surface cleaning
Pill throwing equipment is first applied to the surface of cast steel and cast iron parts and the removal of oxide skin.
Almost all cast steel, gray castings, malleable steel, ductile iron, etc. have to be cast. This is not only to remove the surface oxide skin and clay sand from the castings, but also an indispensable preparation process before the castings quality inspection. For example, the large gas turbine case must be strictly cleaned by throwing pellets before performing non-destructive inspection to ensure the reliability of the results.. In general castings production, throwing pellet cleaning is an indispensable technique for discovering surface defects such as subcutaneous stomata, slag holes, and sticky sand, cold septum, and skin. Non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., are cleaned up. In addition to removing oxidation skins and discovering surface defects of castings, the main purpose is to remove burrs from pressed castings by throwing pellets and obtain decorative surface quality. Get comprehensive results. In metallurgical iron and steel production, throwing pellets or pickling is a method of mechanical or chemical combined removal of phosphors used to ensure high productivity in mass production of iron and steel. In the production of other alloy steel plates and belts, such as Silicon steel sheets and stainless steel thin plates, it is necessary to annealed during the cold rolling process and then perform pellet or pickling treatment to ensure the surface roughness and thickness accuracy of cold-rolled steel plates.
Workpiece enhancement
According to modern metal strength theory, increasing the displacement density inside the metal is the main direction of improving metal strength. It has been proved that pellet throwing is an effective method to increase the metal dislocation structure. This is more important for some workpieces that can not be further strengthened by phase transition hardening or the implementation of phase change hardening. Parts and components such as aviation, aerospace industry, autos, tractors, etc. are required to be light, but reliability requirements are getting higher and higher. The important technological measures are to improve the strength and fatigue strength of the components by throwing pills.
