3 Technical features of the RD 710
The RD 710 has been designed to allow customers to utilize these benefits and produce high-quality HSS. Not only the size range is pushing the limit, but also the wall thickness is. With up to 1” (25.4 mm) wall, the line is capable to produce thick walled ERW tubes. These dimensional capabilities, combined with production speeds up to 35 m/min allow the RD 710 to run a nominal capacity of 400.000 tons per year.
The line arrangement is quite usual with
a strip preparation area, a horizontal strip accumulator and a strip edge miller. The forming & Welding section houses a lineal preforming section with an integrated flexi- ble breakdown stand, three fin pass stands and a Sizing and Shaping section with six stands to produce the accuracy needed for the hollow sections.
The Quick Change System, paired with the X-pact® Quicksetting system supports the production line, reducing the changeover times to below 2 hours.
