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 ...
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 ...
Key features of alumina/magnesia/graphite refractories for steel ladle lining
(2000-08-01)
The corrosion resistance of resin bonded alumina/magnesia/graphite refractories containing different kinds of aggregates were investigated when submitted to the action of slags of several CaO/SiO2 ratios. The laboratory ...
Reaction behavior of magnesium orthotitanate and calcium titanate with compounds of portland cement and their use in a chrome-free refractory

Ceramic coating for refractories protection against carbon oxidation, Part 1: Protection mechanisms
(1999-03-01)
For retarding carbon oxidation in refractories during the preheating of metallurgical furnaces, a ceramic coating, made mainly of sodium phosphosilicate and clay was developed. The coating presents high adherence to the ...
