Danieli to Supply New Long Products Minimill for Deacero
Dec. 29, 2009 Deacero, Mexico, recently awarded Danieli an order to supply a new minimill for the production of deformed bars, and smooth and deformed wire rod.
The new production unit is to be built at Saltillo, near the Monterrey facilities. Its meltshop, which will comprise a 150-tonne EAF, 150-tonne Twin Ladle Furnace, and 6-strand continuous caster equipped with PowerMould™, will be capable of producing up to 1.5 million tonnes of 130- to 200-mm billets per annum.
A 120-tonne/hour walking beam reheating furnace will be directly connected to the continuous casting machine for hot charging of billets to the rolling mill.
The new facility’s rolling mill will comprise a 21-stand continuous mill and a 10-pass high-speed twist-free finishing block for the wire rod line, fed by rolled stock coming from the upstream pre-finishing mill. On-line water quenching and self-tempering of rebars will be performed by QTB lines, located at the finishing stand’s delivery side. The rolling mill will have an annual capacity of approximately 0.8 to 1 million tonnes.
Danieli Automation will supply the electricals and a fully integrated automation system, while the reheat furnace will be supplied by Danieli Centro Combustion. Danieli’s scope of supply also includes the installation of a new LPP-type mill for micro-profiles, starting from round bar in coils produced in the new wire line.
With this added capacity, the Mexican Group led by the Gutierrez family will be capable of producing approximately 4 million tonnes of long products per year.
Startup of the new facility — the 4th minimill that Danieli will supply to Deacero — is scheduled to begin at the end of 2011, with the rolling mill area as first priority.
Deacero, Mexico’s largest steel producer, operates ten steel production facilities: Acería Laminación Saltillo; Saltillo; Celaya; Acería; Industriales; México; Morelia; Guadalupe; Monterrey; and Puebla.
