Hydraulic Roll Gap Control (GAP Control)
Developing hydraulic and automation systems enable the use of ferrous (steel) and non-ferrous (aluminum and copper) metal flat product rolling processes in the sector. Rolling thins the material's thickness in sheet form. While this process occurs, sensors (linear rulers) monitor the rollers' instantaneous positions on the rolling mill and control them with high precision through a closed-loop control method over servo valves. With its advanced technological infrastructure and expert team, Rota Teknik has successfully executed Hydraulic Roller Gap Control (GAP Control) in numerous projects.
Solutions Partner in the Expanding Sector
Many manufacturers in today's industry consistently invest in their facilities to maintain and target their customer markets. They closely follow developments in the sector in mechanical, electrical, and automation systems and aim for specific criteria when making investments. These criteria include broadening the production range, creating new steel types (product range), enhancing product quality, increasing plant productivity, improving plant availability, boosting product efficiency and operating profitability (yield), enhancing the plant's overall working efficiency (overall efficiency), and reducing product cost (cost). In an increasingly competitive, globalized world, product quality and price become crucial factors in determining market presence. As the iron and steel industry continues to grow globally, Rota Teknik emerges as an excellent solutions partner with 25 years of industry experience.
Fast Efficient Control
Industrial users purchase steel only when it's processed into an intermediate form. Customers' requirements have become more precise in recent years. High tensile steels for ever-thinner sheets reduce vehicle weight and fuel consumption. Simultaneously, quality requirements have significantly increased, particularly in dimensional accuracy. Rota Teknik conducts extremely fast and efficient controls to compensate for material thickness differences with high dynamics at elevated rolling speeds. Operators can flexibly adjust different sheet thicknesses via the HMI-Human Machine Interface (Operator Panel), minimizing process changeover times.
The hydraulic automatic measurement control system operates wear-free, producing direct linear movements without mechanical transmission elements. It requires minimal maintenance and is designed for ambient conditions in rolling mills. It compensates for differences in the rolled material's thickness with high dynamics, even at high rolling speeds. Rota Teknik has demonstrated its capabilities in industrial applications with its Hydraulic Roll Gap Control (GAP Control). Using Rota Teknik's closed-loop multi-axis control automation software ensures that the thickness reaches the desired value with micron precision. Valves are mounted directly on the hydraulic cylinder for optimal hydraulic functions. Integrated, highly dynamic servo valves assume full control of position, force or pressure, and speed.
Casting liquid metal into cast-iron permanent blocks and allowing it to solidify ingots. Hot rolling the ingots yields blooms, slabs, and billets as the first product. Re-rolling blooms, slabs, and billets generates products such as profiles, rails, bars, sheets, and pipes. Hot rolling typically initiates the transformation of ingots into blooms, slabs, and billets. Rota Teknik's extensive technological expertise in hot and cold rolling processes meets all global requests and needs in this context. The industry imposes increasingly stringent demands on steel, aluminum sheets, and foil production. Rolling mills can satisfy these requirements with Rota Teknik's hydraulic control systems. These complete systems with high-precision control combine accuracy with robustness and peak efficiency. Rota Teknik consistently offers the latest technology as a solution by developing and installing highly dynamic automatic controls. Rota Teknik's experience and expert staff flawlessly integrate the advantages of robust hydraulics with advanced control technology, understanding the harsh conditions' requirements in daily use.
