零件热处理后清理氧化皮最广泛采用的方法是噴干砂,近年来也采用噴丸和拋丸清理。但是,当零件是在机械加工工序之間进行热处理或加工留量極小时,就不能用铁丸清理,也不能用鉄丸清理工具,因为铁丸会損坏工具的切削刃。在这些情现下,只能用砂清理。干砂清理有一些缺点:噴砂工人会患矽肺病;此外,灰塵对于鄰近的設备,特別是精密設备有不良的影响。齐略宾斯克斯大林拖拉机制造厂制造了并在生产中采用了水砂清理設备,用以清理切削工具的氧化皮和所有不能用铁丸清理的零件的氧化皮。 圖1是一个双室水砂清理設备的总圖。
Part of the most widely used method of cleaning oxide scale after heat treatment is spray dry sand, shot peening and shot blasting are also used in recent years. However, when the part is heat treated between machining operations or the machining allowance is minimal, it can not be cleaned with iron pellets or with a pellet cleaning tool because the pellets can damage the cutting edge of the tool. Under these circumstances, you can only clean it with sand. Dry sand cleaning has some disadvantages: sandblasting workers suffer from silicosis; in addition, dust has a detrimental effect on neighboring equipment, especially precision equipment. Stalin’s Stalin tractor manufacturing plant manufactures and uses in production water sand cleaning equipment to clean the scale of cutting tools and the scale of all parts that can not be cleaned with iron pellets. Figure 1 is a general overview of a two-chamber water sand cleaning facility.
