BAZAN, VANESA; BRANDALEZE, ELENA; PARRA, ROBERTO  e  GONI, CHRISTIAN. PENETRATION AND DISSOLUTION OF REFRACTORY OF MAGNETITE - CHROME BY FAYALITE SLAG. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.173, pp.48-55. ISSN 0012-7353.

Magnesium-chrome refractory have been used with success at high temperatures in different metallurgist processes, such as iron and steel, cement industry and non ferrous pyrometallurgist processes. In particular in the smelting, in the processes of reforming of raffinate of copper. Those materials have good characteristics in relation with the use and the requirements of heat shock resistance. However, they represent an important problem for the environment. The aim of this research was to investigate the interactions between the slag generated in the converter Peirce-Smith in copper and Magnesium-chrome refractory bricks. The infiltration events and chemical attacks in the refractory material caused by the slag formed during the copper conversion process have been studied by means of the development of the different laboratory tests at temperatures of until 1300 ° C.

Palavras-chave : copper; refractory; wear; slag.
