1. 1. The Influence of Drawing Speed on Steel Wire Surface Quality

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Felicia Viklund; Amanda Lundin Bornström; [2022]
   Keywords : carbon steel; wire drawing; drawing speed; surface roughness; defects; kolstål; tråddragning; draghastighet; ytjämnhet; defekt;

   Abstract : Tråddragning är en kallbearbetningsprocess där tråd dras genom en dragsten, som plastiskt deformerar materialet och reducerar tvärsnittsarean. En viktig parameter i tråddragningsprocessen är draghastigheten - en ökad draghastighet kan förbättra produktiviteten, vilket är önskvärt för företaget Suzuki Garphyttan AB då efterfrågan på produkter har ökat.

3. 2. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jacqueline Pierri; [2021]
   Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

   Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE

5. 4. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Brianna Kilberg; [2020]
   Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

   Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE
