1. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization
Sammanfattning : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. LÄS MER
2. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging
Sammanfattning : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. LÄS MER
3. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging
Sammanfattning : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. LÄS MER
4. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process
Sammanfattning : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER
5. Study on the Interaction between Refractory and Liquid Steel Regarding Steel Cleanliness
Sammanfattning : The present thesis focuses on the interaction between refractory and liquid steel. The aim of this work is to understand the interaction behavior between refractory and liquid steel regarding steel cleanliness. The effect of different refractories on different inclusions in Al-killed steel was studied in a furnace. LÄS MER
