▎ 摘　　要

NOVELTY - Preparing high strength cold rolling strip steel comprises (i) taking the aluminum powder, transferring to 800-820°C for 20-30 minutes, cooling with the furnace, and transferring to 100-120°C for 1-1.5 hours to obtain the pre-oxidized aluminum powder, (ii) taking titanium carbide powder, ultrasonically cleaning with acetone for 50-60 minutes, soaking to concentrated hydrochloric acid, drying to obtain the pre-treated titanium carbide powder, mixing the nickel sulfate, ammonium sulfate and aqueous ammonia to obtain the reaction liquid, transferring the reaction liquid to the high pressure kettle, adding pre-treated titanium carbide powder, heating to 130-140°C, filling hydrogen, (iii) taking graphene, copper powder, zirconia ball blending, adding anhydrous ethanol, ball milling for 3-4 hours under nitrogen environment, sieving to obtain the slurry, (iv) taking the strip steel substrate, transferring to the sodium hydroxide solution, alkali washing for 20-30 minutes. USE - The method is useful for preparing high strength cold rolling strip steel. ADVANTAGE - The method improves bonding performance with the strip steel matrix, improves corrosion resistance of the strip surface, improves surface hardness, enhances wear resistance is enhanced, and has high practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for high-strength cold-rolled strip steel.
