  1. 1. Data Generation in Metal Recycling Using Unconditional Diffusion Models

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Andersson Sebastian; [2023]
    Nyckelord :Machine learning; diffusion model; unconditional diffusion model; data generation; generative model;

    Sammanfattning : Combitech AB was interested in how to automate the process of annotating aluminum scrap when it was adjacent to other metals. This was to ultimately create an annotated dataset that could be utilized for training a segmentation model. The idea was to make use of generative models to generate samples of general scrap metals.

  2. 2. Restprodukter inom skrotbaserad stålindustri – en fallstudie av Uddeholms AB. Värdeskapande materialströmmar och industriell symbios för ökad samhällsnytta

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Ola Ohlsson; [2022]
    Nyckelord :steel industry; steel slag; by-products; scrap-metal; drivers; barriers; Earth and Environmental Sciences;

    Sammanfattning : A variety of excess material is produced in the processes used in the scrap-metal based steel industry. The largest stream of material, by volume, is steel slag. Since slag material has very different properties and wide differences in its chemical composition its usage can be found in different sectors. LÄS MER

  3. 3. Application and Evaluation of Current Guidelines for Metal Additive Manufacturing

    Master-uppsats, Lunds universitet/Innovation

    Författare :Robin Bergman; [2022]
    Nyckelord :additive manufacturing; laser powder bed fusion; thin-wall structures; design for additive manufacturing; design guidelines; Technology and Engineering;

    Sammanfattning : The goal of this thesis has been to evaluate the design guidelines that currently exist regarding designing for metal additive manufacturing (AM). More specifically, this project has focused on the design guidelines regarding thin-walled features and how well they work when applied to adapt an industrial part for manufacturing with the AM process laser powder bed fusion (L-PBF).

    Sammanfattning : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. LÄS MER

    Sammanfattning : Stena Recycling is one of the leading recycling companies in Sweden and at their facility in Halmstad, 300 tonnes of refuse are handled every day where aluminium is one of the most valuable materials they sort. Today, most of the sorting process is done automatically, but there are still parts of the refuse that are not correctly sorted. LÄS MER
