Development of an innovative technology for producing thin sheets with controlled stresses from post-production waste from structural steel sheet rolling mills.
The purpose of this project is to develop a pilot installation for the production of sheets and formats of defective DC01-DC06 steel coils from various sheet rolling mills. The applicant plans to develop a technology for repairing defective metal coils together with a dedicated pilot installation. To this end, studies will be carried out at the outset to determine the most common defects in the waste raw material. This information will be used to prepare a matrix of the most common imperfections in 6 categories. For each of them, a sheet straightening process will be defined taking into account the defects occurring in a given class. As a result, it will not be necessary to carry out detailed tests to identify each batch of material before starting production of sheets from recycled raw materials. Manufactured sheets and formats on the pilot installation will be designed for the automotive industry. DC01-DC06 steel is used for the manufacture of automotive parts such as: body parts, mounting elements of various types of shields, electrical and electronic components. The objectives of the project will be achieved through the implementation of a research agenda consisting of 3 stages (2 industrial research and 1 development works). The first phase of the project will focus on identifying the defects in the reckling raw material and defining the parameters of the cold rolling process and between operating heat treatment. The second stage will consist of developing the heat treatment process and the parameters of the straightening process. In stage 3, the applicant will focus on the construction, testing and optimisation of the pilot installation. At this stage, test sheets of sheets will also be produced. A unique feature of the installation will be installed
