摘要： The object of the present invention is to provide a spray-on (gunning) refractory composition having high anti-stripping property, adhesive strength and corrosion resistant property suitable even for high temperature operation in steelmaking furnace. To refractory materials, resol type phenolic resin powder, being in semi-melting state at 80.degree. C. to 500.degree. C. and having weight average molecular weight of 1,000 to 15,000 and residual monomer of not more than 1,000 ppm, or phenol-formaldehyde resin powder, being in heat melting, self-hardening state at 100.degree. C. to 500.degree. C., having weight average molecular weight of 1,000 to 15,000 and residual monomer of not more than 1,000 ppm, and containing reactive methylol group by 6 to 9 weight %, said phenol-formaldehyde resin powder being added by 2 to 10 weight %, and pitch with high softening point of 100.degree. C. to 500.degree. C. being added by 2 to 10 weight %.
