Announcing the contract award on Tuesday, Primetals Technologies said it will supply a 180-ton twin RH degasser, a single-strand slab caster and material handling equipment for AM/NS Calvert LLC’s planned meltshop addition. 

Primetals Technologies said the degasser will be equipped with its combined vessel and ladle lifting system, a combined oxygen-burner system (COB lance), mechanical vacuum pump, ladle treatment stands, wire feeder station, argon stirring emergency lance, and level 1 and level 2 automation systems.

The caster will be configured to produce slabs in thicknesses ranging from 235 mm to 255 mm. With a radius of 9 m, the caster will feature a straight mold with segmented strand containment as well as a patented continuous bending and straightening process, Primetals Technologies said. 

Once operational in 2023, the meltshop will be able to produce 1.5 million metric tons of slabs in-house. The mill broke ground on the meltshop in February.
