Fed by upstream Danieli casters it will produce 1 Mtpy of wirerod coils.
Hoa Phat, the largest steel producer in Vietnam, renewed its trust in Danieli with the order for the new, 1M-tpy rolling mill for wirerod, to be installed at the Dung Quat complex. This will be the third rolling mill for long products in Dung Quat - all of them supplied by Danieli. Fed by 12m-long, 150-mm-square-billets produced by the upstream Danieli continuous casting machines, the new mill will produce 5.5- to 25-mm dia wirerod coils, in low-, medium- and high-carbon grades.
The rolling line is comprised of a high-speed free-rougher followed by an intermediate mill rolling on two strands. After that, bars continue on two independent rolling lines made of pre-finishing cantilever stands followed by 10-pass wirerod blocks adopting semi-multidrive technology for improved management of rolling rings and reduced spares inventory.
Finished product quality is monitored in real time by Hi-Profile measuring devices, while water cooling lines installed before and after (across) the fast finishing blocks, together with the 95-m-long cooling conveyors provide the desired final mechanical characteristics to the finished products, according to the different sizes and steel grades.
Pinch rolls and oil-film bearing laying heads will guarantee the best coil shape and surface quality.
The complete electrical and automation system for the entire line is supplied by Danieli Automation.
