The invention relates to a production technique of hot-rolled strip steel for cold-rolling hot-galvanizing. The production technique is characterized in that converter blowing and ladle argon blowing are utilized to control the components of molten steel: 0.06%-0.09% of C, 0.35%-0.42% of Mn, 0.02%-0.025% of S, 0.018%-0.022% of P, 0.1%-0.16% of Si, 0.004%-0.006% of Als, 0.035-0.042% of Ni and 0.027%-0.031% of Gr; and hot-rolling is utilized to control the heating temperature at 1150-1250 DEG C, the finish rolling start temperature at 1000+/-20 DEG C, the finishing temperature at 900-920 DEG C and the coiling temperature at 600-640 DEG C. The technique lowers the desulfurization, dephosphorization and decarburization strength under the condition of no refining furnace; and the product has favorable cold-rolling physical properties and favorable hot-galvanizing properties.
