ABSTRACT:
An anti-oxidation agent for preventing oxidation of a stainless steel strip during continuous annealing comprising a colloidal inorganic substance which can be crystallized at a temperature not higher than 1300.degree. C. at least one compound having a melting point not higher than 1300.degree. C., selected from the group consisting of silicates, borates and phosphates, a dispersion agent, and the balance substantially water. The anti-oxidation agent is applied to the surface of the stainless steel strip. During the annealing, the anti-oxidation agent enhances the heat absorption so that the stainless steel strip temperature is elevated to the annealing temperature in a short time. The anti-oxidation agent on the strip surface forms a film of a fine structure which keeps the strip surface away from oxidizing components of the annealing atmosphere so as to suppress generation of oxide scale. The film is easily separated due to thermal contraction in the course of the cooling after the annealing.
