decrease in mechanical properties. CGI is stable over a range of approximately 0.006% magnesium. At the upper end of the stable range, increases in magnesium or inoculation can quickly lead to porosity defects, resulting in leakage failures after machining. Process control is of the utmost importance in the production of complex components such as cylinder blocks and heads. In preparation for the start of series production, Tupy
ordered a System 3000 Plus process control system from Swedish CGI specialist SinterCast. It will automatically control the base treatment, process control measurement and final adjustment of magnesium and inoculant prior to casting. “Te process flow and the design of the wirefeeder
enclosures were jointly developed by Tupy and SinterCast engineers based on the experience gained from more than 10 years of CGI series production and the running produc- tion of 18 series production components and more than 55,000 tons per year at the three Tupy foundries in Brazil and Mexico,” said Dr. Steve Dawson, president and CEO, SinterCast Ltd., Sunninghill, U.K. Tupy plans to continue to expand its CGI capabilities in
Saltillo, including future CGI series production on its com- mercial vehicle line. “Te CGI process at Saltillo has been designed from a
clean sheet of paper, incorporating Tupy’s high volume CGI production experience and taking advantage of the latest technology in every aspect of the process,” said Luiz Tar- quínio, president and CEO, Tupy. Process data will be compiled into a database to enhance control and traceability. The Tupy system will be SinterCast’s most comprehensive installation, with
械性能下降25-40%。CGI中添加不超过0.006%的镁 时，性能依然保持稳定。但是在稳定范围极限位置， 再增加镁或者孕育剂，都会快速导致缩松缺陷形成， 机加工后会有渗漏故障。在例如缸体和缸盖这种复杂 件的生产中，过程控制显得最为重要。 系列生产开始的准备工作中，Tupy 从瑞典CGI专 业化厂家 SinterCast定了一台附加过程控制系统的 System 3000. 该系统可以自动控制铸造前的原料处 理，过程控制测量以及最终的镁和孕育剂的调整。 “工艺流程以及喂丝罩是由Tupy和SinterCast的工 程师联合设计的，基于Tupy在巴西和墨西哥的3个铸 造厂超过10年、量产18种产品,每年55000吨以上的 CGI系列生产中积累的经验”，SinterCast首席执行官 Steve Dawson博士说。 Tupy计划继续扩撒萨尔提略的蠕墨铸铁产能，拓展 到未来的商务车生产线上的蠕墨铸铁系列产品。 “通过Tupy的大批量蠕墨铸铁件生产经验，同时利 用工艺过程中许多方面的最新技术，萨尔提略的蠕墨 铸铁生产过程已经实现了完全无纸化设计”，Tupy首 席执行官Luiz Tarquínio说。
过程参数将被收集到一个数据库中，以增强控制性 和可追溯性。Tupy系统将是SinterCast的最全面安装
The System 3000 collects melt- ing, molding, pouring and shake- out data into a single database, including thermal analysis results and process data, for advanced traceability.
