Abstract
A particulate composition suitable for use in a process of dressing a refractory structure which includes the steps of projecting against a site of refractory structure to be dressed a comburent gas stream carrying a mixture comprised of fuel particles and refractory oxide particles, which fuel particles are comprised of at least one element which is oxidisable to form at least one refractory oxide; and causing or allowing the fuel particles to burn, the particulate composition being a mixture including fuel particles comprised of at least one element which is oxidisable to form a refractory oxide; refractory oxide particles; and particles of fluxing agent the fluxing action of which is such that when the mixture is projected in a comburent gas stream and the fuel particles are caused or allowed to burn, the refractory structure becomes softened to an extent such that the refractory structure becomes dressed by removal or displacement of material thereof under the mechanical action of the impinging comburent gas stream.
