The invention discloses a production method of a micro-titanium enhanced steel belt for hot rolling stamping based on a sheet billet flow, and belongs to the technical field of metallurgy plate. The steel belt comprises the chemical components by the weight percentage: 0.04-0.06% of C, not more than 0.03% of Si, 1.30-1.50% of Mn, not more than 0.020% of P, not more than 0.008% of S, 0.020-0.040% of Ti, 0.020-0.040% of Als, not more than 0.0050% of N, and Fe and inevitable residual elements. The method adopts the processes: smelting with a revolving furnace, refining with a LF furnace, continuous casting, heating with a heating furnace, scale removal with high-pressure water before rough rolling, rough rolling with two machine frames, scale removal with high-pressure water before finish rolling, finish rolling with five machine frames, laminar cooling, and coiling. Through low carbon, high manganese and micro-titanium enhancement composition design and reasonable continuous casting, heating, rolling and cooling processes, the cold-formed micro-titanium enhanced steel belt for hot rolling stamping and with good welding property is produced.
