A methodology to investigate the wear of blast furnace hearth carbon refractory lining
(Wiley-Blackwell, 2013-11-01)
In this work it is presented a methodology applied by Companhia Siderurgica Nacional (CSN, Brazil) in order to assess its blast furnace 3 carbon refractory hearth lining conditions. The aim of the investigation was the ...
Heating time required for an MgO-graphite refractory during a hot modulus of rupture test
(2006-09-01)
In the work described in the present paper, an analytical solution of the general heat conduction equation was employed to assay the temperature profile inside a solid slab which is initially at room temperature and is ...

Slag corrosion of alumina-magnesia-carbon refractory bricks: Experimental data and thermodynamic simulation
(Elsevier, 2017-04-27)
Alumina-magnesia-carbon (AMC) bricks are used in steelmaking ladles, where they are part of the bottom and sidewalls working linings. These refractories can be corroded by liquid slag, especially during tapping and casting. ...
Citric acid as anti-hydration additive for magnesia containing refractory castables
(ELSEVIER SCI LTD, 2011)
Magnesia hydration is a key concern in refractory castable processing. The volumetric expansion that follows this reaction can result in cracks or even explosion during the first heating-up. Citric acid (CA) and other ...
Definition of Uveitis Refractory to Treatment: A Systematic Review in the Absence of a Consensus
(2020)
Purpose: To evaluate the different definition of refractoriness in uveitis in the literature.
Methods: We systematically searched the literature in order to identify definitions of refractory noninfectious uveitis in adult ...
Factors controlling the mechanical behavior of alumina-magnesia-carbon refractories in air
(Elsevier, 2016-04-07)
This work analyzes the mechanical behavior of alumina-magnesia-carbon (AMC) refractories in air up to 1260 °C. AMC refractory bricks are used on sidewalls and bottoms working linings of steel-making ladles. In plant, AMC ...
