The invention relates to metallurgy field, in particularly to a granular carbonizing rice husk thermo to insulating agent used in iron and steel melting progress. The invention is characterized in that: the thermo of the insulating agent consists of 45 to 80 percent carbonizing rice husk, 10 to 30 percent binder and 1 to 30 percent filling material. The binder refers to one of or a combination of at least two components among amylum, caustic soda flake, bentonite, white putty waterglass, sodium carboxymethyl cellulose (CMC), phosphoaluminate cement and silicate cement. The thermo-insulating agent contains comparatively high carbonizing rice husk, and effectively bonds the carbonizing rice husk into granule shape while at the same time avoids the adoption of calcareousness and dolomite, so as to preserve insulation property of the thermo-insulating.
