铸件清理作业的主要内容包括去除铸件上的砂子、芯子、浇冒口和毛刺。近几年来,随着先进铸造技术的不断采用,铸件清理的工作量虽在逐步减少,但迄今为止,它在铸件生产的总劳动量中仍占有很大比重,铸钢件要占25～30％,铸铁件要占15～20％;就清理费用来说,铸钢件约占铸件总成本的35％,铸铁件约占25％。因此,如何提高清理作业的生产率,改善清理工作条件,对发展铸造生产具有重大意义。从目前来看,清理作业落后于铸造生
The main contents of the casting cleaning operations include the removal of sand castings, cores, pouring risers and burrs. In recent years, with the continuous use of advanced foundry technology, although the workload of the casting is gradually reduced, so far, it still accounts for a large proportion of the total labor in the production of castings, steel casting accounts for 25 to 30 %, Cast iron parts to account for 15 to 20%; to clean up costs, castings account for about 35% of the total cost of castings, castings account for about 25%. Therefore, how to improve the productivity of cleaning operations and improve the working conditions for cleaning up are of great significance to the development of foundry production. From the current point of view, cleaning operations lag behind casting students
