With a total investment of 21.5 million euros, the company has built one of the most advanced facilities in Germany for the production of high-quality, heat-treated steel bars made from recycled material. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Single-bar heating: The heating process for premium-quality steel<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">EVA systems operate using a precise heat treatment process: Steel rods made from recycled scrap are heated to up to 880\u00b0C depending on their material properties, then quenched and tempered to 550\u2013700\u00b0C. This process makes the material both stable and ductile\u2014ideal for high-stress applications in wind turbines, the automotive industry, aerospace, and agriculture. <\/p>\n\n\n\n<div style=\"height:35px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The Assignment<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Georgsmarienh\u00fctte GmbH needed two plants for the production of high-quality, heat-treated steel bars from recycled scrap, with the following requirements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Full digital integration into existing production systems<\/li>\n\n\n\n<li>Real-time monitoring of all process-related data<\/li>\n\n\n\n<li>Complete traceability of every single rod<\/li>\n\n\n\n<li>Compliance with international quality standards (AIAG CQI-9, ASTM A1100)<\/li>\n\n\n\n<li>Seamless integration into the existing infrastructure (brownfield project)<\/li>\n\n\n\n<li>100% electric operation using green electricity<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This complex automation solution was to be implemented in collaboration with ITG Induktionsanlagen GmbH, which served as the general contractor.<\/p>\n\n\n\n<div style=\"height:35px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Control Technology and Digitalization: Our Solution<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ROTH implemented the complete <a href=\"https:\/\/roth-gruppe.de\/en\/control-technology\/\" target=\"_blank\" rel=\"noreferrer noopener\">control systems and <\/a> <a href=\"https:\/\/roth-gruppe.de\/en\/?page_id=8302\" target=\"_blank\" rel=\"noreferrer noopener\">digitalization for <\/a>both EVA plants:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Central control room with highly automated process control<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Both systems are controlled from a central control room with minimal manual intervention. This enables rapid adaptation to various material parameters and ensures maximum safety through continuous process monitoring. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>PLC Programming for Precise Process Control and Integration of Equipment<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The programmable logic controller was custom-programmed for precise process control, integration of all auxiliary units (cooling systems, recooling unit, air extraction and purification system), integrated fire protection, and safe process operations with redundant safety systems.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Level 2 integration with real-time data transmission and an order management system<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Full integration into the GMH Level 2 system enables real-time transmission of all process-relevant measurement values, a connection to the customer\u2019s fully digitized order management system, and automatic data collection for quality assurance and traceability.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Full traceability and HMI user interfaces<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Each rod is tracked throughout the plant with full traceability and documented process data. After leaving the plant, the bars are sorted into bundles. The highly digitized <a href=\"https:\/\/roth-gruppe.de\/en\/?post_type=service&amp;p=8054\" target=\"_blank\" rel=\"noreferrer noopener\">HMI interfaces<\/a> provide an intuitive and transparent display of all process parameters and real-time visualization using Siemens WinCC.
