  1. 1. Optimizing Porosity Predictions in Casting Simulation

    University essay from KTH/Materialvetenskap

    Author : Sanna Kylström; [2022]
    Keywords : ;

    Abstract : Porosity is a defect severely affecting component quality and performance. In order to improve predictions, simulations can be utilized to calculate possible initiation sites. READ MORE

  3. 2. Aspects of gating system improvement in a cast iron foundry

    University essay from KTH/Materialvetenskap

    Author : Fahami Annan Green; Felix Göttfert; [2021]
    Keywords : Gating system; Cast iron; Foundry; Pouring basin; Offset step basin; Sprue; Ingjutssystem; Gjutjärn; Gjuteri; Gjutskål; Förskjuten steggjutskål; Nedlopp;

    Abstract : The gating system transfers the iron melt from the ladle to the void in the casting mould. The gating systems dimensions and designs are crucial for the success of a casting and a poor gating system is a leading cause of scraps. READ MORE

  4. 3. Inoculant measurement with thermal analysis

    University essay from KTH/Materialvetenskap

    Author : Christopher Armstrong; [2020]
    Keywords : Thermal Analysis; Inoculation; Nucleation; Compacted Graphite Iron; CGI; Cast Iron; Material Properties;

    Abstract : Over time the level of inoculant will decrease due to fading and this needs to be compensated bymore additions of inoculant. When casting CGI400 at Scania a one-step method is used, and the inoculant additions are based on the last ladle from the previous oven. READ MORE

  5. 4. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE
