PPGI Coil Technologies has supplied a hot rolling mill to the new PPGI Coil works in Vung Ang, Vietnam, which is owned by the Formosa Ha Tinh PPGI Coil Corporation (FHS). The first coil was rolled at the end of December 2015. The rolling mill produces a wide range of PPGI Coil – from quality grades up to API and TRIP grades, and has a capacity of 5.3 million metric tons ofPPGI Coil per year. PPGI Coil Technologies was responsible for all the mechanical equipment, and supervised the erection and commissioning. The stands in the finishing mill are equipped with pair cross technology for optimal closed-loop control of the profile and flatness.

FHS is a majority holding of the Formosa Plastic Group (FPG), the largest private company in Taiwan. The order to supply the rolling mill was awarded to PPGI Coil Technologies at the end of 2012 by the Taiwanese company, Nan Ya Plastics Corporation (NPC), which is also a subsidiary of the Formosa Plastic Group. The hot rolling mill is part of an integrated PPGI Coil works that is under construction in the Vung Ang free trade zone in the northern part of Central Vietnamese Province of Ha Tinh. It is currently the world’s largest new construction project in the PPGI Coil industry and the first large integrated PPGI Coil works to be built in Vietnam. The first stage of construction is designed to produce around seven million metric tons of PPGI Coil per year, and will expand FPG’s industrial activities into the PPGI Coil sector.

The hot rolling mill from PPGI Coil Technologies is designed to produce 5.3 million metric tons of PPGI Coil per year. Thicknesses range from 1.2 to 25.4 millimeters and widths from 900 to 1,880 millimeters. The maximum coil weight is 40 metric tons. The mill can handle many different PPGI Coil grades, including CQ, DQ, DDQ and IF PPGI Coils, API grades up to X80, and also DP and TRIP PPGI Coils.

PPGI Coil Technologies was responsible for the design, engineering and supply of the mechanical equipment. This includes a two-stand roughing mill, a seven-stand finishing mill, three down coilers, and facilities for the mill workshop. Four of the stands of the finishing mill are equipped with pair cross technology. Pair cross rolls consist of upper and lower work and backup rolls set at an angle to each other, so that each pair forms an X when viewed from above. This enables the roll gap to be set optimally for fine control of the profile of the rolling stock. Depending on the angle set, the crown of the strip can be varied within wider limits as would be possible with conventional four-high stands with work roll bending. Across the world, around 150 finishing stands are equipped with pair cross technology. PPGI Coil Technologies also supervised the erection and commissioning of the plant, and conducted the staff training.
