Coiler needed for high-strength grades and thick strips

The 2,250mm hot strip mill at Baosteel Zhanjiang mill which is supplied by SMS group, started operation at the end of 2015. It has a designed annual capacity of 5.5 million tonnes and is designed to produce hot strip with final thicknesses between 1.2-25.4mm and widths from 800-2,100mm.

The new coiler will be positioned downstream two existing coilers installed as part of the first construction phase. The new one will be designed for strips of greater final thicknesses and higher strengths, such as tube and pipe steels of strength classes X100 and X120 or ultra-high-strength strips of 1,200N/mm².

To coil such materials, the new coiler will be equipped with reinforced mechanical components such as a pinch roll unit and hold-down rolls with aprons for safe and reliable wrapping of the strip head around the coiler mandrel.
