and increased melt quality. “Te closed system minimizes temperature fluctuations and oxide formation,” said Peter Reuther, European sales director, StrikoWestofen. “In addi- tion, the melt is removed below bath level, thus preventing the entry of oxides and significantly increasing the quality of the melt. Te result is considerably improved productivity in comparison with conventional ladle systems. Up-to-date empirical surveys conducted with a large customer in the U.K. show that 15 to 20 additional castings in one 24-hour shift are not uncommon. Extrapolated over a whole year, we are talking about an additional productivity of about 20,000 euros per dosing furnace. Tis corresponds with an increase in productivity of about 1.5%.” A total of 14 StrikoWestofen dosing systems of varying sizes are operated by the British automobile supplier. Negotiations on another 12 systems for a new production location are pending. Tese benefits also convinced the operators of the Celikel
foundry in Kocael, Turkey. Te company, which produces aluminium diecast parts for household appliances and auto- motive applications, has been operating several StrikoMelter melting systems for more than 10 years. “We had the opportunity to experience StrikoWestofen’s
products and services in day-to-day foundry operation. And we decided on the dosing systems from Gummersbach when planning our new facility,” said Erdem Aydogmus, Celikel foundry manager. “We are expecting the 10 dosing systems that have now been installed to give us a decisive competi- tive advantage. In particular low metal losses, low energy consumption and a low reject rate have a great influence on the unit costs.” According to Celikel, the Westomat dosing furnaces
reduced metal loss by about 80% and energy consumption by approximately 30% when compared with a bale-out fur- nace with a ladle system. At the same time, plant availability increased and, consequently, so did productivity. Being a manufacturer of components for the automotive
sector, Celikel also is interested in high dosing accuracy and optimal, reproducible metal quality. “Tese two aspects really show what our Westomat dosing furnaces are capable of,” said Reuther. “Te closed furnace system gives a higher constancy to the temperature control of the
melt. ■ Visit www.

总监Peter Reuther说：“该闭合的系统可最大限度降 低温度的波动和氧化物的产生。此外，熔体在低于熔池 水平被移除，因此，防止氧气进入，大大提高了熔体 的质量。与传统的钢包系统相比，生产率得到了明显的 提高。目前，根据英国一家大企业的实践经验显示，在 一班24小时生产中，通常可多生产15-20件铸件。一年 内，预计每台配料炉的增产产值约20000欧元，相当于 生产率提高了1.5%。”该英国汽车供应商目前共使用了 14套不同尺寸的史杰克西配料系统。另外12套用于新厂 的购买协议还在谈判过程中。 这些优势使土耳其的Celikel铸造厂充满信心，该厂为 家用电器和汽车提供铝合金压铸件，采用StrikoMelter 熔炼系统已有十多年的历史。 Celikel铸造厂经理Erdem Aydogmus说：“我们有 机会体验和了解了史杰克西公司日常生产的服务及其产 品，因此，我们在新厂规划时就决定使用其配料炉系 统。我们希望已安装的10个配料系统为我们带来一个决 定性的竞争优势。特别的是，低的金属损失，低能耗和 低废品率对单元成本产生巨大的影响。” 据Celikel公司称，与钢包固定炉相比，Westomat 配料炉系统降低约80%的金属损失和约30%的能耗。同 时，设备的使用率提高，从而提高了生产力。 作为汽车零部件生产商，Celikel公司对高配料精度、 最优的可再生的金属质量感兴趣。Reuther说：“这两 方面的确体现了Westomat配料炉的性能，闭合炉系统
使熔体的温度控制具有高度稳定性。” ■ 更多信息，请访问
