Al Hot Rolling Mills
Al Hot Rolling Mills Aluminium boasts an optimal strength-to-weight ratio, high energy efficiency, high tolerance to extreme temperatures as well as excellent forming properties and resilience. Thanks to all these positive properties, aluminium has become an indispensable raw material for the most important industrial sectors of our modern world in recent years. Aluminium is already used in all industries where weight savings, stability, a low coefficient of expansion and high corrosion resistance are required. The fields of application are manifold and form a cross-section of the most important industries in our globalised world. Another advantage of aluminium is its almost unlimited recyclability. Not least for this reason, many manufacturers rely on aluminium as a material in their productions as part of sustainability initiatives, because the recycling process of aluminium requires only 5% of the original manufacturing energy. This is a clear contribution to climate protection because CO2 emissions, and thus the greenhouse gas emissions generated during production, can also be significantly reduced. So there are many reasons why aluminium has become an indispensable raw material of tomorrow. In 2015, for example, more than 58 million tonnes of aluminium were produced worldwide; by 2021, this figure had already risen to around 68 million tonnes. The raw material for further processing is produced in aluminium casting and rolling mills. Here, in the first production step, impressive aluminium ingots are cast, which are then rolled into aluminium strips, trimmed and finally wound into coils. Each of these production steps is controlled and optimised through the use of high-precision automated measurement and control technology. The highest availability and reproducibility of all measurement results form the basis for an optimal, automated control of the production processes. Only through this 100 % automation is it possible to effectively increase output while simultaneously reducing the reject rate. For the production of flawless end products, our customers have a wide range of measuring systems at their disposal for the fulfilment of all relevant measuring tasks in: • casting mills • hot strip lines As standard, the product portfolio of measuring systems optimised for aluminium hot rolling mills includes solutions for the precise determination of: • slab dimension • thickness • thickness profile • length • width • temperature • speed • 2D surface inspection Customised special designs are of course also possible. 18 19
