摘要： In processes of forming a refractory mass on a surface, a mixture of refractory particles and oxidizable particles which react exothermically with oxygen to generate sufficient heat to soften or melt at least the surfaces of the refractory particles are sprayed against that surface to bring about formation of said refractory mass. To promote the reliable and consistent formation of a durable refractory mass, the granulometry of the particles which are sprayed in the mixture is such that the 80% and 20% grain sizes of the refractory particles (that is, the screen mesh sizes G.sub.80 and G.sub.20 through which respectively 80% and 20% by weight of the particles will pass) have a mean greater than the mean of the 80% and 20% grain sizes of the oxidizable particles and the size range spread factor f(G) of the refractory particles is at least 1.2, where ##EQU1## In a composition of matter for spraying against a surface to form a refractory mass, which consists of such a mixture, the granulometric requirements are the same, and the exothermically oxidizable particles are present in an amount between 5% and 30% by weight of the mixture, and the granulometry of said particles is such that the mean of the 80% and 20% grain sizes of the refractory particles is greater than the mean of the 80% and 20% grain sizes of the oxidizable particles and that the size range spread factor (as herein defined) of the refractory particles is at least 1.2.

摘要： A method of repairing an eroded refractory wall pierced by one or more openings using a ceramic welding technique. A member of shape substantially complementary to the desired shape of the repaired opening is placed into each opening so that the member projects from the refractory wall by an extent at least equal to the local depth of erosion. Such complementarily-shaped member is so composed that it is adapted to withstand ceramic welding temperatures. A desired refractory repair mass is built up, by ceramic welding, adherent to the eroded wall and surrounding the complementarily-shaped members(s) while leaving its end or their ends exposed, and the complementarily-shaped member(s) is or are thereafter removed from the repaired openings(s). Such complementarily-shaped member may, for example, be of refractory carbon or of steel, such as stainless steel. Such a steel member may be tubular for the circulation of coolant.

Such addition is made using one or more vitreous silica bricks bonded into position by projecting a mixture composed of finely divided particles of exothermically oxidizable material, e.g. Si optionally with Al and particles of silica, and burning the mixture during its projection to form a coherent refractory mass which bonds the addition together and to the original structure.

摘要： A method of manufacturing a composite refractory article having a flow passage through which a molten metal stream may be conducted and comprising a first body of refractory material which defines a surface of that passage, the first body being bonded to a second body of refractory material.

Within the passageway, the first body of refractory material is provided for defining the flow passage surface, the first body being formed in the larger passageway by causing its refractory material to cohere and bond to the second body by fusion or partial fusion in situ.
