1. Direct Reduced Iron Production from EAF Slags in Fixed Bed Furnace
Master-uppsats, KTH/Materialvetenskap
Författare :Idil Bilen; [2013]
Nyckelord :;

Sammanfattning : Electric arc furnace (EAF) slags are basic characteristic slags that include approximately 40 % iron oxide compounds. Iron oxide can be recycled and re-used in the process to decrease amount of waste product besides reducing loss of raw materials. LÄS MER
2. Modeling of electric arc furnaces (EAF) with electromagnetic stirring
Master-uppsats, KTH/Materialvetenskap
Författare :Niloofar Arzpeyma; [2011]
Nyckelord :electric arc furnace; electromagnetic stirring; natural convection;

Sammanfattning : The influence of electromagnetic stirring in an electric arc furnace (EAF) has been studied. Using numerical modeling the effect of electromagnetic stirring on the thermal stratification and fluid flow has been investigated. LÄS MER
3. Reaction mechanisms in the ferrosilicon production process:
results from an industrial furnace excavation
Uppsats för yrkesexamina på avancerad nivå, Luleå/Tillämpad kemi och geovetenskap
Författare :Mats Andersson; [2009]
Nyckelord :Ferrosilicon production; furnace excavation; electric arc; furnace;

Sammanfattning : The purpose of this work was to re-assess the metal forming reactions taking place in the electric arc furnace during ferro silicon production. The different phases and reaction zones close to, or nearby the crater walls formed by the electric arc, were of special interest in this thesis. LÄS MER

4. Melting - pre-study of models and mapping: physical
modeling of scrap melting
Uppsats för yrkesexamina på avancerad nivå, Luleå/Tillämpad fysik, maskin- och materialteknik
Författare :Marianne Östman; [2006]
Nyckelord :smältning; smältmodell; melting model; ljusbågsugn; electric; arc furnace; EAF; scrap melting; skrotsmältning; melting;

Sammanfattning : A lot can be won by better use of the steel. For example the higher strength the less material is needed and less material gives easier transportation, less discharge and energy and need less resource. Scrap has been used in steel industry for over a century. LÄS MER
