Retrofit Blast Wheel Cuts Cycle Time, Pays Back in Two Months 改进抛丸机切割周期，两个月收回投资
Steel caster Monett Metals Inc., Monett, Mo., USA, was
looking to improve the performance of its blast equipment, which had cycle times reaching 15 minutes. Blast equipment relies on its wheel’s ability to clean parts
correctly. Wheel parts are the highest wear components of any surface preparation system. A poorly operating wheel due to misalignment of the internal wheel parts results in expensive downtime and maintenance time, longer cycle times and re-cleaning of parts. Rather than replacing its blast equipment, Monett Met- als assigned Wheelabrator Plus, La Grange, Ga., USA, the task of providing a retrofit replacement EZEFIT wheel with a cast manganese housing that met the following criteria: 1. greatly reduce blast cycle times; 2. greatly reduce or eliminate the need to re-clean parts by cleaning parts to satisfaction the first time;
3. be retrofit on equipment not made by Wheelabrator; 4. be installed by Monett Metals employees to further save money. Te first EZEFIT wheel was installed in Spring 2009, ac-
cording to Monett Metals President Jay Triplett. Te investment in the retrofit wheel was paid back in less than two months. “For minimal payback investment, we received an excel-
lent return. Normally we look for payback in one year from capital investments,” Triplett said. “We have greatly reduced our cycle times from 15 minutes to three minutes. In other words, our capacity has increased five times.” Monett Metals installed the second wheel in Spring
2010. Installation took less than a day. “Tis was an easy installation for us,” Triplett said. “We
wished we had done this two years ago.” Castings are noticeably cleaner after a three-minute blast
cycle with the retrofit wheels, according to maintenance manager Steve Rowden.
美国密苏里州的莫内特Monett钢连铸机金属公司希 望提高抛丸机性能使循环周期达到15分钟。 抛丸机通过轮子来精确地清理零件表面。轮子是任 何表面处理系统中最容易磨损的零件。由于内部轮子的 偏心而导致的错误操作将导致停机、维修甚至要重新清 理零件。
莫内特金属公司没有更换设备而是委托位于美国佐治 亚州的La Grange的Wheelabrator Plus工厂加更换了 带锰保护层的EZEFIT轮子，该轮子符合以下标准： 1. 大大降低了周期； 2. 大大减少和消除了返工； 3. 对非Wheelabrator生产设备改进； 4. 后续安装工作由莫内特公司完成，节省了成本。 根据莫内特金属公司总裁Jay特里普利特所说，第一 批EZEFIT轮子在2009年春季安装。改进工作用了不到 两个月时间。 Triplett说： “对于最低回报的投资，我们已获得了 良好的收益。通常我们投资后一年才能得到收益。而现 在我们已经使周期从15分钟降低到3分钟，换句话说， 我们的资金提升了5倍。” Triplett说：“莫内特金属公司在2010年春天安装 第二台。安装工作不到一天就完成了，因为这对我们 来说是已经一项很简单的工作。我们真希望两年前也 这么做。”
根据维修经理Steve Rowden所说，铸件在3分钟的
