The Dynamic Wetting Characteristics Of Ladle Slags On Spinel, Hamed Abdeyazdan, Neslihan Dogan, Muhammad Rhamdhani, Michael W. Chapman, Brian Monaghan

Brian Monaghan

Inclusion removal by slag is primarily achieved by optimizing process conditions that promote slag contact with the inclusion. For efficient inclusion removal the inclusions must adhere to the slag phase. The strength of the attachment can be characterised by the wettability of the slag on the inclusions.

Behaviour Of New Zealand Ironsand During Iron Ore Sintering, Zhe Wang, Harold Rogers, David Pinson, Brian J. Monaghan, Sheng Chew, Paul Zulli, Sharon Nightingale, Guangqing Zhang

Brian Monaghan

Titanium-bearing burdens are commonly introduced into blast furnaces to protect the hearlh because the so-called "titanium bear" which is a precipitate of carbide, nitride and carbonitride of titanium may form in the blast furnace hearth if Ti02 is present in the feed [1 , 2J. New Zealand ironsand is a titanomagnetite, containing around 60 wt.% iron, 8 wt.% titanium and other substances such as silica, phosphorus and lime [3, 4]. Since it is competitive in price, introduction of the ironsand into the ferrous feed can reduce the production cost and potentially increase blast furnace campaign life. An appropriate method of …

Inclusion Reactivity: Morphology And Composition Changes Of Spinel (Mgal2o4) In Steel, Neslihan Dogan, Raymond Longbottom, Mark Henry Reid, Michael W. Chapman, Paton Wilson, Les Moore, Brian Monaghan

Brian Monaghan

Due to an ever increasing demand for cleaner, high quality steels, there is an increasing push for steelmakers to lower the non-metallic inclusion contents of the steel they produce. Understanding inclusion reactivity in steel is key in producing high quality steels at high production rates. Our current knowledge in controlling and predicting inclusion development during liquid steel processing is limited. In this study, spinel (MgAI204) inclusions of close to stoichiometric MgO.AI2O3 and known size distribution where added to the liquid steel bath prior to assessing their reactivity. The pO2 of the gas phase was controlled to 10-13 atm throughout the …

Interfacial Assessment Of Cao-Al2o3-Sio2-Mgo Slags On Mgal2o4 Spinel, Hamed Abdeyazdan, Neslihan Dogan, M Akbar Rhamdhani, Michael Chapman, Brian J. Monaghan

Brian Monaghan

Steel cleanness is an important and growing research area driven by the demands to produce high quality steel. Lowering the inclusion content in steel is an important criterion for clean steel. It is therefore important to better understand the interaction between inclusions and slag to improve the removability of inclusions from liquid steel. For efficient inclusion removal the inclusions must attach/bond with the slag phase. The strength of the attachment can be characterised by the wettability of the slag on the inclusions. In this study, the dynamic wetting of ladle slags of the CaO-Al2O3-SiO2- MgO system on a solid spinel …

Strength And Bonding In Reduced Ironsand-Coal Compacts, R J. Longbottom, B J. Monaghan, S A. Nightingale, J G. Mathieson

Brian Monaghan

In this investigation, the strength and bonding within reduced ironsand-coal compacts were studied, with the aim of better understanding the binding mechanisms in the reduced compacts and, based on this understanding, to improve their strength. Ironsand ore and sub-bituminous coal were mixed and pressed into compacts, which were reduced by heating in a thermogravimetric furnace to temperatures between 1273 and 1573 K under argon. The progress of the reaction was monitored by measuring the weight loss with time. The reduced compacts were found to have low strength in compression testing. The main form of bonding between the reduced ironsand particles …

Political Influence Associates With Cortisol And Health Among Egalitarian Forager-Farmers, Christopher Von Rueden, Benjamin C. Trumble, Melissa Emery Thompson, Jonathan Stieglitz, Paul L. Hooper, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Background and objectives: Low social status increases risk of disease due, in part, to the psychosocial stress that accompanies feeling subordinate or poor. Previous studies report that chronic stress and chronically elevated cortisol can impair cardiovascular and immune function. We test whether lower status is more benign in small-scale, relatively egalitarian societies, where leaders lack coercive authority and there is minimal material wealth to contest.

Methodology: Among Tsimane’ forager-horticulturalists of lowland Bolivia, we compare informal political influence among men with urinary cortisol, immune activation (innate and acquired), and morbidity as assessed during routine medical exams.

Results: After …
