Record results for long-product minimill New productivity record for the Danielli bar and wire rod mill

A Danieli bar and wire rod mill, installed at Rajhi Steel, in Saudi Arabia in 2010, has achieved a productivity record. The facility produced 101,036 tons of finished product during March 2020, and a total of 286,312 tons during the first quarter of the year. The Rajhi Steel long-product minimill is designed to produce 1 million tonnes per year of deformed bars between 10mm and 40mmdiameter, and plain/deformed wire rod of 5.5mm to 16mm diameter, in low-, medium- and high-carbon steels. The mill comprises a 100 ton AC Danarc ® EAF and LF, 5/6-strand billet caster for 130mm to 160mm billets, and a 1,380,000

Nm 3 /h dedusting plant to treat primary and secondary fumes. It rolls billets from a 200 ton per hour re-heating furnace at 40m per second, onto a bar cooling bed equipped with a double twin-channel system for bar braking and discharging. Wire rod coils are produced at 105m per second. The bar finishing mill features two, 4-pass DWB Delta-type, high speed finishing blocks and an in-line QTB water- quenching system for weldable deformed bars with high tensile strength. The wire rod finishing mill includes a 10-pass, DWB finishing block and controlled cooling line with QTR water cooling.
