e saw how essential a cooling system is to the International Space Station in December 2013, when one coolant pump failed. Tat left only one other pump to
provide cooling for the station’s vital electrical and life- support systems. Tis required a crew member to make an emergency spacewalk to swap a spare for the pump that had failed. With its new pump in place, the station was back in the space exploration business. While it might not be rocket science, when it comes to
cooling, induction melting is as dependent on an effective cooling system as the International Space Station. Without adequate cooling, induction furnaces are not able to operate. And in the worst cases of cooling system failures, furnaces have been damaged or destroyed, endangering workers and causing significant damage to the foundry. Metalcasting cooling systems normally operate quietly
in the background and receive regular attention only from the maintenance personnel tasked with keeping them run- ning. Te goal for this article is to provide useful insights into the design and operation of effective and efficient induction melt shop cooling systems, with real-world illustrations drawn from a new system installed at Chas- six Columbus Casting Operation, Columbus, Ga., U.S. Chassix is a $1.2 billion global company headquartered in Southfield, Mich., serving automotive customers from 25 locations in eight countries. Its Columbus facility melts 240,000 tons of ductile iron per year.
013年12月，当一个冷却泵故障，我们看到了 冷却系统对国际空间站是多么重要。仅剩的另 外一个泵运转的冷却系统，保障空间站重要的 电气和生命维持。这需要宇航员进行紧急太空行走， 取备用泵更换故障泵。随着新泵的就位，空间站可继 续太空探索旅程。

虽然不属于火箭科学，但是涉及到冷却，感应熔炼与 国际空间站一样依赖有效的冷却系统。如果没有足够的 冷却，感应炉将无法运行。而在冷却系统故障的最坏的 情况下，感应炉被损坏或摧毁，危及工人安全并给铸造 厂带来巨大的损失。
铸造厂的冷却系统通常在后台悄悄运行，并接受维护 人员定期的检查使它们保持可靠运行。本文的目的是希 望通过美国乔治亚州哥伦布市Chassix铸造公司安装新 系统实际案例，给出设计感应熔炼车间有效和高效的运 行的冷却系统的有益的见解。Chassix公司是一家总值 约为12亿美元的全球性公司，总部位于密歇根州南菲尔 德市，给8个国家25个地区的汽车行业客户提供服务。 其位于哥伦布市的工厂年熔化球墨铸铁24万吨。
冷却系统的基本构成
Chassix’s old cooling tower and pumps lacked the capacity required to cool all the furnaces at the same time, limiting production.
Chassix公司旧的冷 却塔和泵无法同时冷 却所有炉子，制约了 生产。
