The invention relates to a high-strength cold-forming hot-continuous-rolling steel plate and the manufacture method thereof, wherein, the chemical composition of the steel plate is as follows: 0.05wtpercent to 0.10wt percent of C, 0.10wt percent to 0.50wt percent of Si, 1.0wt percent to 2.0wt percent of Mn, less than or equal to 0.025wt percent of P, less than or equal to 0.010wt percent of S, 0.03wt percent to 0.08wt percent of Nb, 0.05wt percent to 0.15wt percent of Ti, 0.10wt percent to 0.50wt percent of Mo, 0.0010wt percent to 0.0050wt percent of Ca, 0.01wt percent to 0.05wt percent of Aland the rest, Fe and other inevitable impurities; the technical process of the steel plate includes hot metal deep desulfurization to converter top and bottom blowing to secondary refining to continuous casting (machine cleaning) to hot charging hot feeding soaking pit to plate blank reheating to controlled rolling to controlled cooling to coiling to finishing. With the yield strength reaching 700 MPa, the steel plate has excellent mechanical property and processing properties such as welding and roll forming; meanwhile, because less alloying element is added during the manufacture process ofthe steel plate, the invention has low production cost and convenient operation during big production without adopting heat treatment processes such as tempering and quenching and tempering. The invention can be used in fields such as engineering machinery and structural parts and container for special vehicle and strongbox, etc.
