Efficient Trim removal plant for endless strips of slitter machine in production of Foil of Aluminium
Relocation and redesign succesfully completed.
Ohle / Plettenberg – December 2022
As part of the doubling of its capacity for annealed aluminum strip at its Ohle site, Novelis opted for the construction of a new, additional continuous annealing furnace. This involved a comprehensive modernization of the existing Trim removal plant for endless strips including innovative dust extraction technology.
As early as 2021, Schuh Anlagentechnik conducted a detailed inventory of the existing air handling systems. Based on this, a new concept for optimizing theTrim removal plant for the endless strips and dust extraction system were developed jointly with Novelis at the beginning of 2022. The goal was to integrate the new continuous annealing furnace into the existing production structure.
In May 2022, Novelis commissioned the redesign of the edge strip extraction and disposal technology.
Modern Trim removal plant for endless strips with efficient dust removal technology
The project involved the planning, delivery, installation, and commissioning of the new pipe system with high-performance conveying fans. These enable the reliable bridging of the additional pressure losses while integrating existing system components.
A completely new system for edge strip disposal was installed for the new continuous annealing furnace, consisting of:
- Schuh Cutting Device and Schuh Chopper Fans for precice cutting of the endless strips
- Schuh Conveying Fan to overcome pressure losses and ensore the safe waste diposal
- Separator to split the conveying air and the cutted Aluminium strips
- Separator device to ensure the split of different types of waste material
- High permance Schuh Pulse Jet Sleeve Filter for filtering the transport air
The dust generated during the cutting and shredding process is efficiently filtered by the Pulse Jet Sleeve Filter and removed in an environmentally sound manner via radial fans and silencers.
This allows the system to meet modern requirements for emission control and occupational safety..
Implementation without production interruption
Following order placement in May 2022, assembly work began in July 2022. By the time of cold commissioning in November 2022, over 1,300 meters of piping had been installed.
The conversion work on the four existing plants was successfully completed in December 2022. Recommissioning took place without any significant production interruptions – a major advantage for ongoing operations.
Outlook: Central Trim Removal Plant for endless strips
The new production hall for the second continuous annealing furnace is currently under construction. Following completion of the construction work, the new central roadside waste disposal plant will also be commissioned. Commissioning is planned for summer 2023.
