<p>Brazil-based steel producer Gerdau awarded Danieli Automation/DIGI&MET the orders for the modernization of the core functions of the automation control systems of billet caster 2, rolling mill 1 and rolling mill 3 operating in its Cosigua unit in Brazil’s Rio de Janeiro state, supplied by Danieli. There, about 1 million tonne per year of long products are produced overall.</p> <p>The new automation system for the six-strand billet caster, which now will integrate also the logic for the cooling bed, is the first of three orders awarded in a row. Prewired and pre-tested automation panels will be designed to minimize wiring and installation, maintaining most of the cables already in place. The run-out control will be performed using single-billet laser position sensors for billet length accuracy. A new, ergonomic main control desk, 3Q HMI system and local boxes will be provided to support user activities during on-field operations.</p> <p>The second order is to revamp automation for rolling mill #1, which produces small profiles and rebar, focusing on modernization of the mill speed master control, including new hardware. All HMI screens will be redesigned as per Danieli Automation 3Q standard. A Danieli Automation exclusive technological workstation will handle mill know-how settings and the automatic interaction with the entire rolling mill through the master control.</p> <p>In addition to mill speed master control and technological workstation, as for rolling mill #1, the modernization of rolling mill #3 –which produces straight bars– includes the upgrade of the auxiliary services and shear controls, along with the supply of new Pulpit and 3Q-HMI control desk and 3Q HMI.</p> <p>The original equipment supplied by Danieli Automation to Gerdau’s Cosigua unit has been operating for more than 20 years.</p>
