material warm does not need a burner of its own, as it is heated by the flue gases of 700 to 800 degrees Celsius. At the same time, a slight overpressure is generated which prevents oxygen from entering and thus reduces the loss of aluminium, caused by burn-off, to a number between 0.5 and 0.8 percent. Fur- thermore, the special facilities are equipped with an insulating shell made of special concrete. That shell keeps the temperature within constant at 1000 to 1100 degrees Celsius, depending on the alloy, and reduces the radiation of heat to the outside to only 40 to 60 degrees above the room temperature. As a result of this insulation less heating energy has to be procured, which has a positive effect on the consumption of combustibles as well as the emissions of CO2. Further, a specially developed control system regulates the burners as well as the supply of cool air, according to the current demand. Twelve furnaces by ZPF therm are already in use in the
wider area of Shanghai. The prospect of using less energy permanently, of reducing the running costs and of meeting the new legal conditions makes the furnaces very interesting for the whole aluminium industry – despite the necessary initial investment. As with most investments in eco-friendly tech- niques the expenses are put into perspective by the cost-saving opportunities in the long run. According to that, the expert on economy, Cheng Siwei explained as a reply to the question, whether the latest trend would threaten the profit of compa- nies that for a short time companies may lose money during the adjustment to a sustainable business model, however, in the long run it is cost-effective. Meanwhile the ZPF Group has increased its market pres- ence in Asia with a subsidiary in Taicang near Shanghai. In the future, the new company, ZPF Industrial Furnaces Co. Ltd, is supposed to produce the power-saving installations for foundries in Southeast Asia that are built the same way as the ZPF Therm furnaces developed and produced in Siegelsbach. At the beginning of the year 2011, the company group had already opened a representative office in Shanghai. ■ Besides the headquarters ZPF Therm Maschinenbau GmbH,
ZPF Group includes ZPF Services GmbH, ZPF Foundry4 GmbH as well as ZPF Industrial Furnaces Co., Ltd. Since its foundation in 1993, ZPF Therm has developed to one of the internation- ally leading manufacturers of aluminum melting furnaces. The company group currently employs about 80 employees. The parent company is seated in Siegelsbach, Baden-Wurtemberg. As a systems supplier, ZPF Group offers a comprehensive product range, from melting and holding furnaces, chip melting installations up to automatic dosing machines.
止氧气进入，并使因熔损造成的铝损耗降低到0.5-0.8% 。另外，此紧凑结实的设备拥有一个专用水泥隔热套。 视合金成分不同，此套将使内部温度恒定地保持在 1000℃到1100℃之间，还能降低向外的热辐射，使其 仅高于室温40℃到60℃。采用了此隔热功能后所需供 应热能较少，这就给燃料消耗和CO2排放带来了积极的 影响。另外，专门为之开发的控制系统将根据当前需求 对燃烧器以及冷却空气输入进行调节。
在大上海地区早已安装了十二台ZPF热能机械有限公 司的熔化炉。从长期来看，这些设备消耗较少的能源， 降低了运行成本，并且满足新的法律条件，整个铝制品 行业对此设备表示了极大的兴趣-尽管在开始时必须进 行必要的投资。与大部分环保型设备的投资一样，从长 期来看，节约所获使支出显得很少。就当前趋势是否威 胁到了企业的利润，经济学家成思危也这样解释道，短 期来看，企业在向一个可持续商业模式转变时将花掉一 些钱，但长期来看却是划算的。
同时，ZPF集团在上海附近的太仓市开设了子公司， 以增进亚洲市场表现。在未来，这家ZPF工业炉公司将 会为东南亚公司生产节能装置，与德国Siegelsbach研 发生产的装置相同。2011年初，该公司已经在上海开 设了代表处。■
除了ZPF热能机械总部之外，ZPF集团还包括ZPF服 务有限公司、ZPF铸造公司和ZPF工业炉公司。自1993 年建立以来，ZPF热能已经发展为世界领先的铝熔炉生 产商。集团公司现有约80名雇员，母公司位于巴登 - 符 腾堡州的Siegelsbach市。作为一个系统供应商，ZPF 集团提供广泛的产品链，从熔炼保温设备、碎屑熔炼装 置到自动加料机。
“We have been dealing with ‘Green Technolo- gies’ for 15 years due to the high standards in the European protection of the environment” explains Holger Schwarz, Sales- Manager Asia/Pacific at ZPF therm’s.
“出于欧洲环保高标准 的缘故，我们在15年 前就开始采用”绿色工 艺”了”， ZPF热能 机械有限公司亚太销售 经理Holger Schwarz 表示。
十月中旬，太仓ZPF工 业炉公司开始启动，这 是ZPF集团在德国之外 的首个生产公司。
