Siemens Metals Technologies提供的耦合腌制线倾斜冷磨坊（PLTCM）是在5月底为Valin Arcelormittal Automotive Steel Co.（VAMA）委托的。这条线是中国湖南省的Loudi新的冷滚动综合体的一部分。
The first extension stage will produce 1.5 million metric tons of cold strip per annum, including high-strength steel grades for applications in the automotive industry. The cold rolling mill has been designed with the capability to be expanded at a later stage of time to reach an annual production of two million metric tons.
VAMA is a joint venture of ArcelorMittal and the Chinese companies Valin Iron & Steel Group Co., Ltd. and Hunan Valin Iron & Steel Co., Ltd. The production plant in Loudi will supply the Chinese automotive industry with high-quality sheet metal. Siemens provided all the mechanical and electrical equipment for the coupled tandem pickling line, as well as ancillary equipment, such as the hydraulic and pneumatic systems, and the safety engineering. The PLTCM has a common, all-embracing automation system, comprising basic (level 1) and process automation (level 2), as well as special process models. This enables high availability and output to be achieved while maintaining constantly high product quality. The systems and components used are part of the Siroll CM solution concept specifically developed for cold rolling mills. Siemens also supervised the installation and commissioning of the tandem pickling line.
串联线由四个六高的滚动架组成，额定功率为每台7,000 kW。最大滚动力为35,000 kN。这使得极高的强度钢可以在紧密的公差内滚动。智能皇冠与特殊的执行器和控制系统一起确保成品具有所需的平坦度。C-Block带有一个集成的卷更换系统，用于液压自动量规控制（HAGC）的杆型，长冲程圆柱体，旋转木载盘和捕获的循环器，首次在耦合的串联串联腌制线中使用。条带的进入厚度为1.8至6毫米，而出口厚度在0.5至2.5毫米之间。线卷带，宽度为900至1,890毫米。最大滚动速度超过1,400 m/min。该线可以处理许多不同的钢级等级，包括温和的钢，高强度，低合金钢，各种IF钢，DP，Trip和BH（烤制）等级，最高钢钢，抗张力为1,200 n/mm²。
