In aluminum foil production, challenges arise in the real-time monitoring and control of technological parameters and temperature control during casting and rolling, leading to significant raw material and energy losses. Malfunctions and disruptions in the thermal conditions of the caster-roller cause a reduction in continuous casting billet quality. This paper proposes elements of a specialized system for data analysis and process monitoring of continuous casting for high-strength aluminum alloys grades 8011 and 8006, presented as a universal architecture of the industrial process based on the thermal field modeling of caster-rollers. Existing automated control systems for continuous casting of aluminum strips either lack the appropriate software or rely heavily on imported solutions. This study lays the groundwork for developing an automated control system for the continuous casting. Initial matrices were obtained to build a mathematical model of strip deformation in the “metal-roller” contact zone and the “bushingroller” zone, based on the thermal field data for caster-rollers during the casting and rolling of aluminum alloys 8011 and 8006. The research results and proposed approaches will be beneficial for practical applications in industry and for use in other secondary metallurgy processes, including aluminum foil production in Vietnam.
