FORMING COHERENT REFRACTORY MASSES

摘要

FORMING COHERENT REFRACTORY MASSES In a process of forming a refractory mass in which solid particles of exothermically oxidisable material having an average grain size of less than 50 ? m are burned while mixed with solid particles of at least one incombustible refractory material during projection of the mixture against a surface to form a coherent mass on said surface, the oxidisable material comprises silicon and aluminium, the aluminium being present in an amount not exceeding 12% by weight of the total mixture.
