The Spanish company, SIDENOR ACEROS ESPECIALES, S.L., has placed an order with the SMS group for the modernisation of its bar mill in Basauri.
The goals of the modernisation are to achieve a more effective rolling process and an improvement in the material properties.
The SMS group scope of supply includes all the mechanical, thermal and electrical components, the automation system and the complete erection and commissioning that is scheduled for September 2017.
The existing reversing three-high stand in today’s semi-continuous mill will be replaced by a 6-stand continuous roughing mill with compact stands (CS) in V-H arrangement. In addition, a new crank shear and two further compact stands, also in V-H arrangement, will be installed upline of the existing continuous finishing stands. A further crank shear installed on the delivery side of the bar mill will, in future, allow not only larger cross-sections but also smaller cross-sections to be cut at up to 10 meters per second in the future.
The scope of modernisation also includes the supply of a completely new walking-beam furnace that with its modular design makes allowance for a future increase in capacity. The delivery side of the furnace is equipped with a high-pressure water descaling unit. The furnace will also be equipped with the modern Level 2 automation system, SMS PrometheusTM, an ideal system for setting the heating parameters in accordance with the wide range of steel grades to be rolled. Through the use of SMSZeroFlame flameless burners, pollutant emissions into the atmosphere are minimised.
At the Basauri works, SIDENOR produces round bars in the size range Æ 29 – 100 mm from high-grade carbon steels, low and high-alloy quality steels and tool steels, roller bearing steels and stainless grades that are used in the automotive industry, in oil & gas and in machine and plant engineering.
