Fused refractory oxides improving the lining resistance of the nonferrous metallurgy's thermal vessels

Abstract

The technology for the periclase-chromite refractories based on the fused grains of raised temperature resistance was developed in the article. The technology was created for the fused grains-based periclase refractories with the high performance temperature (1900 °C) and elevated heat resistance. The self-propagating high-temperature (SHS) technology was developed for the refractory materials and on base of this technology the fusedcast
refractory products, brick-work mortars, gunning mixtures for the hot gunning were manufactured. The refractory materials were produced on an industrial scale at the JSC «Magnesit Works». These materials were used for the most wearing lining parts such as the horizontal converters tuyere zones, ore-thermal furnaces (OTF) slagline areas, Waeltz-kilns, OTF blast-holes components, oxygen flash smelting vessels roofs, Vanukov  furnaces. The lining resistance was elevated by the factor of 1,5‒2,0. Ill.1. Ref. 7. Tab. 6.
