More Information
Summary:The invention discloses a protective curing coating for the surface of a fiber furnace lining of a cold-rolling continuous annealing furnace. Raw materials of the coating include, by weight, 30-40% ofzirconium-containing aluminum silicate powder with a particle size less than or equal to 10 [mu]m 30-40%, 10-20% of light floating beads the particle size of which is 100-300 microns, 2-6% of activeAl2O3 powder the particle size of which is less than or equal to 10 microns, 2-6% of fumed silica the particle size of which is less than or equal to 40 nm, 1-4% of zirconium-containing aluminum silicate fiber sections, 5-10% of magnesium oxide active powder the particle size of which is less than or equal to 10 microns, and 30-40% of an inorganic composite adhesive. The protective curing coatingcan resist high temperature of 1000 DEG C, has the advantages of high surface hardness, high bonding strength with a furnace lining interface, capability of resisting scouring of furnace gas at 40-45m/s, good thermal shock stab
