Abstract: In a process of dressing a refractory structure, a comburent gas stream carrying a mixture of particles is projected against the site to be dressed. The particle mixture comprises particles of one or more elements which is or are oxidizable to form one or more refractory oxides ("fuel particles") together with refractory oxide particles and the fuel particles are caused or allowed to burn during projection. The mixture further incorporates a fluxing agent, the fluxing action of which is such that under the heat released by combustion of the fuel particles, the refractory structure becomes softened to an extent such that the structure becomes dressed by removal or displacement of material thereof under the mechanical action of the impinging stream.Suitable fuels include very fine particles of aluminum and/or silicon. Suitable fluxes include fluorides and compounds of metals other than those whose oxides are projected in the mixture, for example alkali metal compounds, especially salts selected from borate, sulphate, carbonate and phosphate.

Abstract: In ceramic welding processes, oxidising gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder becomes at least partially melted or softened and a cohesive refractory mass is progressively built up against that surface. In order to reduce any tendency for the weld mass to include a low-grade refractory phase and thus promote the refractoriness of that weld mass, the fuel powder is present in a proportion of not more than 15% by weight of the total mixture and includes at least two metals selected from aluminium, magnesium, chromium and zirconium, and in that at least the major part by weight of the refractory powder consists of one or more of magnesia, alumina and chromic oxide, and in that the molar proportions of silica and calcium oxide present in the refractory powder (if any) satisfy the following expression: molar concentration of SiO.sub.2 in % .ltoreq.0.2+molar concentration of CaO in %

Abstract: A process of forming a coherent refractory mass on a surface comprises projecting against that surface, together with oxygen, a mixture of refractory particles and fuel which reacts in an exothermic manner with the projected oxygen to release sufficient heat to melt at least the surfaces of the refractory particles and thus form the refractory mass. The projected mixture contains, as fuel, finely divided particles of at least one element which is oxidizable to form a refractory oxide and it also contains carbonaceous particles which are of such a size or composition that carbon particles become occluded in the formed refractory mass. The mixture may contain, as said fuel, finely divided particles having a mean grain size of less than 50 .mu.m of silicon, aluminum and/or magnesium. The carbonaceous particles may comprise a carbonaceous core which is covered by a mantle inhibiting oxidation of the core. The mixture may further contain particles comprising a core of at least one element which is oxidizable to form a refractory oxide which is covered by a mantle inhibiting oxidation of the core. Suitable mantle materials include metallic oxides, nitrides and carbides.
