An experimental study of bubble behaviour at liquid-liquid interfaces
Moe, Kristian Ringheim (Master thesis, 2022)I metallindustri er tapping en prosess som kan tilføre mye luft til det smeltede metallet og flytende slagget. Dette kan medføre transport av metall inn i slagget via stigende metalldekkede bobler. Målet med denne oppgaven ... -
Experimental and Numerical Study on Tapping of Two Liquids through a Single Tap-Hole
Loomba, Varun; Olsen, Jan Erik Øvrebø; Reynolds, Quinn Gareth; Oxtoby, Oliver; Einarsrud, Kristian Etienne (Journal article; Peer reviewed, 2023)The production of industrial metals in pyrometallurgical smelting furnaces is central to modern industry. Tapping of metal and slag from smelting furnaces is a complex and difficult process. Any variations from tap to tap ... -
Lab-Scale Physical Model Experiments to Understand the Effect of Particle Bed on Tapping Flow Rates
Loomba, Varun; Pourfallah, Hesam; Olsen, Jan Erik; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2022)Optimal tapping of metallurgical furnaces is required for efficient furnace operation. Improper tapping can lead to metal and slag accumulation in the furnace thereby reducing the process efficiency. The mass flow rate of ... -
Metal and Slag Extraction from Different Zones of a Submerged Arc Furnace with Non-uniform Porous Bed Using CFD
Loomba, Varun; Olsen, Jan Erik; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2022)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ... -
A Review of Ferroalloy Tapping Models
Bublik, Sergey; Olsen, Jan Erik; Loomba, Varun; Reynolds, Quinn Gareth; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2021)Tapping is an important furnace operation in the ferroalloy industry and poses a number of complex and coupled challenges of both practical and economical importance. Owing to the hazardous high-temperature conditions ...
