01.07.2021. The Hyper UC-mill supplied by Primetals Technologies produced the first coil at Ho Chi Minh steel mill of Maruichi Sun Steel Joint Stock Company (SUNSCO). This is the first Hyper UC-mill in Vietnam, and by adopting the smaller diameter work roll drive with MH Spindle that withstands high load, it can reduce rolling loads while maintaining the high shape control capability of the UC-mill.
Market for thinner cold rolled materials
The purpose of this project is to accommodate the growing demand for thinner cold rolled materials. This new light-duty Hyper UC-mill enables to reduce investment and maintenance costs. SUNSCO will build a stable position in the growing market for thinner cold rolled materials.
Scope of supply
Primetals’ 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 mm in thickness and 1,250 mm (4 feet) in width.
The Hyper UC Mill is a technology recently developed to realise 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.
SUNSCO
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 galvanised 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.
