Protection mechanisms of blast furnace hearth linings achieved through titanium additions to the burden
(2003-12-01)
The protection mechanisms of refractory linings both at the slag and pig-iron levels associated with conventional techniques of titanium addition to the blast furnace burden were investigated. The results were derived from ...
Studio di miscele refrattarie per spruzzatura a caldo mediante misura del modulo di rotturaStudy of refractory mixes for hot spraying by means of modulus of rupture tests
(Techna Group, 2006-04)
The modulus of rupture of four different refractory mixtures for coke ovens repair by hot gunning was determined. The materials were characterized by chemical, granulometric and phase analyses, optical microscopy and ...
Temperature and common-ion effect on magnesium oxide (MgO) hydration
(ELSEVIER SCI LTD, 2010)
MgO based refractory castables draw wide technological interest because they have the versatility and installation advantages of monolithic refractories with intrinsic MgO properties, such as high refractoriness and ...
Análise sistêmica dos fornos de cozimento de anodo para a indústria de alumínio
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciência e Engenharia de MateriaisCâmpus São Carlos, 21-05-20)
The recent global economic crisis allied with the trend for sustainable
companies and countries have meaningfully changed the aluminum area.
Previously, the productivity was the main focus of the metal producer and ...
Mechanical behaviour of MgO-C refractory bricks evaluated by stress-strain curves
(Elsevier, 2012-07)
In this work, the mechanical behaviour of a set of resin- and pitch-bonded MgO-C refractories containing metallic additives was evaluated in laboratory tests at high temperature in a non-oxidant atmosphere. Commercial ...
Sintering behavior of periclase–doloma refractory mixes
(Elsevier, 2009-08)
Steelmaking electric arc furnaces (EAF) hearth is usually built up with dry vibratable refractory mixes. During furnace operation, the refractory mix undergoes sinterization, slag attack, and chemical interaction with ...
