Cartiera di Ferrara selected Toscotec for a complete dryer section rebuild of its coreboard machine at Ferrara mill in Italy. The paper machine produces coreboard in the range of 220 to 620 gsm, processing 100% recycled paper. The delivery is scheduled for the third quarter of 2020.
The project includes two dryer sections. In the first part, Toscotec will install new felt, guide and stretcher rolls; it will modify the existing frame structure and supply a new frame section. The second part will be completely new and it will feature 16 new TT SteelDryers of 1,829 mm diameter designed for an operating steam pressure of 10 barg. The scope also includes bearings and housings, steam fits and joints, turbulence bars for the dryer cans, and all the main section components such as felt rolls, stretchers, guiding devices, and doctors.
Toscotec will supply mechanical drives for the entire dryer section in silent drive configuration. The services package includes mechanical erection, supervision, commissioning, and start-up assistance.
The rebuild will increase the mill’s production by 30%. Toscotec will reposition the existing 1,500 mm diameter cast-iron dryers to the first part of the dryer section, and it will implement an increased thermal efficiency in the second part using TT SteelDryers of a larger diameter.
Giulio Spinoglio, President and CEO of Cartiera di Ferrara, says: “Out of the various proposals we evaluated for this project, Toscotec’s rebuild solution was the most compelling one for two main reasons. First, the timeline of the project. Toscotec gave us good guarantees on the PM shutdown time and their previous record of successful rebuilds confirmed their capability to deliver. Second, their technical solution was the most advantageous for us in terms of production increase and energy efficiency. ”
Enrico Fazio, Head of Sales of Toscotec Paper & Board division, says: “Our rebuild solution allows for a significant increase of PM1 production capacity, without changing the length of the dryer section. This means that the positions of the press and the pope reel remain unchanged and that civil works will not be required, thereby significantly reducing the machine shutdown time.”
