The successful implementation of 5-strand rolling at DeAcero Ramos Arizpe (Mexico) (Room 207 C)

Just three days after hot startup, the mill had already demonstrated its full potential by rolling at 70% of its maximum capacity, meaning a very fast ramp-up learning curve. The rolling mill is designed to produce rebar from #3 to #16 on the QTB-Quenching and Tempering line for bars, smooth rounds and squares from 1/2” to 2”, merchant bars, angles, channels, flats and T-profiles. The process technology provides split-rolling of rebar on five strands. The paper presents this 5-strand process, explaining the technological features and the mechanical and automation equipment involved in this new innovative rolling method.
