Composition for the repair by welding on the site of refractory products.

摘要

Composition for the repair by welding on the site of refractory products comprising the constituents oxidizable making it possible, by any means suitable for this purpose, of igniting the said composition projected against the said products to be repaired, by means of any projection system and to bring it to a minimum temperature necessary for the operation, and of the refractory components that are compatible with the said products to be repaired and composed of at least in part of the products of the same nature as the latter. & br / said constituents oxidizable comprise at least of the particles of metallic silicon and aluminum metal and the assembly of these constituents oxidizable represents by weight, up to 30% of that of the said composition, said refractory components comprise at least of the particles of elements of a refractory product different from that of the same nature as the products to be repaired, each set of particles of a same element of the constituents of the composition to a particle size distribution of between predetermined limits.
