每块钢板的重量通常在 20 到 40 吨之间。生产后，表面有鳞片，生锈。户外储存和海运使板坯暴露在恶劣的条件下。装载远洋船只非常耗时，总成本很容易超过几十万美元。 RFID技术提供了许多好处。 RFID 转发器很小，可以存储标记产品的身份，并可以通过天线从几米的距离读取这些数据。但是，钢铁行业对RFID的使用有特殊要求。首先，RFID阅读器的无线电波被金属反射，这给读取带来了很大的问题。其次，它们必须牢固地连接，因为沉重的厚板重达数吨，并且在轮船和火车运输过程中会相互摩擦，导致标签脱落或损坏。

“我们过去曾与其他身份识别公司和系统开发商合作。我们知道，从钢板上弯曲下来的 RFID 标签仍然可以被读取。然而，问题在于其他公司建议的解决方案没有足够的附着力，或者在我们的巴西工厂应用标签需要昂贵的特殊工艺和系统，”Loïc Feinbier 回忆道。这一突破是通过与 S+P Samson GmbH 的专家合作实现的，他们将多年的钢铁物流识别经验带到了该项目中。 S+P Samson 开发了一种由薄膜制成的不干胶标签，它的应答器部分通过一个简单的穿孔像旗帜一样从平板上弯曲，以便可以阅读。另一个好处：可以使用标准的 Lexmark 激光打印机打印 S+P 标签和标签，该打印机安装了一个额外的 RFID 单元，用于写入芯片。由于打印和 RFID 编程同时进行，工作步骤的数量和潜在的错误被最小化，特别是在打印过程中验证 RFID 标签的成功编码。 “RFID 信号在金属环境中的可读性最初被视为主要挑战。有趣的是，通过以直角伸出的柔性标签读取钢铁行业的 RFID 标签比预期的要快得多，也更容易解决。开发一种特殊的粘合剂来将标签粘贴到板坯的粗糙表面上是一个更大的挑战，尽管在潮湿条件或表面问题（如水垢）的情况下仍必须可靠地粘附，”S+P Samson 的贡献的 Karl Tochtermann 解释说到项目的成功。

BlueScope needed to modernize its infrastructure and adopt new technologies to improve operations and supply chain efficiency while maintaining and updating an aging application portfolio.
RobotStudio Case Study: Benteler Automobiltechnik
Benteler has a small pipe business area for which they produce fuel lines and coolant lines made of aluminum for Porsche and other car manufacturers. One of the problems in production was that when Benteler added new products, production had too much downtime.
Continuous Casting Machines in a Steel Factory
With a very broad range of applications, steel is an important material and has been developed into the most extensive alloy in the engineering world. Since delivering high quality is absolutely crucial for steel plants, ensuring maximum productivity and the best quality production are the keys to competitiveness in the steel industry. Additionally, working conditions in steel factories are not suitable for workers to stay in for long periods of time, so manufactures usually adopt various machines to complete the steel production processes. However, the precision of these machines is often overestimated and the lack of flexibility also makes supervisors unable to adjust operating procedures. A renowned steel factory in Asia planned to improve its Distributed Control System (DCS) of furnaces as well as addressing the problem of insufficient accuracy. However, most well-known international equipment suppliers can not provide a satisfactory solution and local maintenance because the project needed new technologies to more accurately control equipment operations. By implementing Advantech’s automated monitoring and control solution, steel factories can not only improve the manufacturing processes but can also allow users to add additional functions to the existing system so as to make sure the operation runs at high efficiency.
