Test & measurement
including the material’s edges, tail and head ends. From an overall production perspective, a control system should be quick and easy to fit, helping to minimise plant downtime during installation or upgrades. The system’s reliability and ability to handle a wide range of steel products while requiring a minimum of service contributes further to the plant efficiency and profitability.
Accurate strip tension measurement is similarly critical to ensuring material thickness and consistency during cold rolling. Maintaining accurate tension is key to achieving the steel’s desired magnetic properties and mechanical strength, while reducing the incidence of defects that can impact severely on production continuity and profitability.
Precisely controlling strip tension plays a vital role in preventing material defects such as buckling, slippage, or strip breaks. Monitoring edge quality and controlling defects prevents damage during handling and processing, while precise control over strip width ensures that the finished material meets the precise dimensional requirements of downstream manufacturing operations. Stringent management of material thickness is also important from a cost efficiency perspective, since rolling a strip to the minimum permissible thickness ensures optimised material usage and reduced waste. Roll force load cells may also play an essential role in silicon steel production, ensuring accurate measurement and control of roll force to maintain consistent deformation of the material at each rolling pass. Accurate control of roll force also helps ensure its uniform properties, while reducing the risks of costly damage to the material. Load cell data is also used for quality assurance purposes and provides valuable insights for mill operators to help with optimising parameters and enhancing the efficiency of cold rolling processes.
