components are generally engineered and made as one-of-a- kind products. EMSS has strict quality controls in place for these components. In addition to visual inspection, castings undergo a magnetic particle test or an ultrasonic inspection to search for cracks in the material. Tis requires a clean surface free of any scale. In the past this surface preparation operation was done manually. “We invested in this new shot blast system primarily
because the stringent customer requirements for improved casting and surface qualities forced us to adopt the cold box casting method for castings with complex geometries,” said Igor Sapetko, foundry manager, EMSS. “However, at the same time, we wanted to improve the working conditions for our employees by eliminating the vibrations, dust and noise caused by manual shot blasting. Tis, by the way, also contributed to a much cleaner environment.” Work piece dimensions of 40 x 23 x 16 ft. (12 x 7 x 5m) and weights of up to 250 metric tons posed a signifi- cant technical challenge for the Rösler engineers. But the engineering task became even more difficult, because the customer specifications called for integrating the shot blast system into the overall EMSS manufacturing line. Te shot blast machine had to be placed on the foundation of an old water jet blast system in a building with numerous support pillars. Rösler engineers also had to ensure that the machine design allowed utilization of the existing rail part transfer system with turn table for transporting the work pieces from the foundry, through the blast machine and to the quality
的功能，尺寸和重量，这些零部件一般只设计和生产 1件。EMSS公司有严格的质量控制，以确保这些零部 件的质量和使用寿命。除了外观检查，铸件还需要磁 粉探伤或超声波探伤来检查材料内部的裂纹。这需要 铸件表面清洁没有任何附着物。以前，这种表面清理 作业是手工完成的。
“我们投资这个新的抛丸系统主要是为提高铸件的 表面质量，由于客户严格的要求，我们不得不采用冷 芯盒工艺以满足铸件复杂型腔的要求。”EMSS公司 铸造经理Igor Sapetko说，“当然，我们也想改善员 工的工作条件，避免因手工清理作业产生的振动、 灰 尘和噪音。而且，也为环境更清洁做出贡献。” 尺寸为40×23×16英尺（12×7×5米），重达250吨 的工件带给Rösler公司工程师非常大的技术挑战。而且 因为EMSS公司要求抛丸设备集成到原来的整条生产线 中，使工程任务变得更加困难。新的抛丸设备必须放置 在原来由许多根支撑柱组成的旧的水爆清砂设备的基础 上。Rösler公司工程师还必须确保工程的设计可以利用 现有的带回转台的轨道运输系统，实现工件从铸造车间 到抛丸机和到质量检验部门的运输。考虑到铸件的重 量，旋转/悬架抛丸系统的设计是不可行的。
