Flat hot rolling is the crucial process that transforms cast slabs into usable steel products like plates and strips. By rolling the steel at high temperatures, it not only achieves the desired shape and dimensions but also refines the material’s internal grain structure. This significantly improves the steel’s mechanical properties, such as strength and toughness, while enhancing its uniformity. As the key stage that bridges casting and cold rolling as well as final finishing, hot rolling determines the fundamental quality and performance characteristics of the steel, making it indispensable for producing the high-strength, durable plates and coils demanded by industries from construction to automotive.
As the quality of the final steel product is fundamentally determined at this stage, a precise and reliable control system is indispensable. Metals-Tech delivers comprehensive electrical and automation solutions for hot rolling mills, encompassing the full spectrum from Level 0 field devices and Level 1 basic automation to Level 2 process control and plant-wide digitalization systems. Our advanced mathematical models, deeply rooted in proprietary process expertise, are integral to these solutions. They play a pivotal role in ensuring precise temperature control, thickness accuracy, profile, flatness and microstructural consistency, directly enabling the production of premium-grade steel.
