The stainless steel composite plate blank is composed of four layers of steel plates from top to bottom, the first layer and the fourth layer are both carbon steel plates with the thickness ranging from 75 mm to 80 mm, the second layer and the third layer are both SUS304 stainless steel plates with the thickness ranging from 12 mm to 14 mm, and the thickness of a rolled finished product is generally 6 mm to 16 mm; the rolling method of the stainless steel composite plate comprises the following process steps which are carried out in sequence: detecting high-temperature mechanical properties of carbon steel and stainless steel, correcting and inputting chemical components, selecting a control model, heating a plate blank, carrying out rough rolling, descaling after a furnace, carrying out finish rolling, carrying out finish descaling, carrying out finish rolling at an outlet, carrying out laminar cooling control and carrying out coiling control. Continuous and large-batch production is smoothly achieved on a t
