First coil produced on Hyper UC-mill supplied by Primetals Technologies

Primetals Technologies' first Hyper UC mill for lightweight construction materials in Vietnam

SUNSCO was established in 1996 as the first 100% foreign capital invested steel company in Vietnam. The company produces and sells the following items: molten zinc, 55% Al-Zn galvanized steel coil, color coated steel coil, and steel pipe. SUNSCO´s products are mainly used for civil and building construction, structural uses, furniture, bicycle and motorbike parts and other industrial uses. The company is part of the Maruichi Group, with Maruichi Steel Tube Ltd. holding 72.53% of the shares.

Primetals Technologies’ scope of supply covered the complete mechanical and electrical equipment, and was responsible for the supervision of installation and commissioning. The light mill will process thin sheets of 0.1 millimeters in thickness and 1,250 millimeters (4 feet) in width.

The Hyper UC Mill is a technology our company has recently developed to realize high reduction capability and shape controllability in High Tensile Strength Steel (HSS) rolling, and can be applied to the rolling of high grade non-directional electrical steel sheets and sheet products. Based on the optimum combination of roll diameters for work rolls, intermediate rolls, and backup rolls, it has the ability to use work rolls with smaller diameters and has high reduction capability. Achieves work roll drive with small diameter spindle.
