The invention relates to the technical field of metallurgy, in particular to a symmetric rolling production process of a large-thickness stainless steel composite plate, which comprises the following steps: (1) preparing a base material and a clad plate, flattening and cleaning the surface, then stacking one clad plate and one base material, carrying out vacuum seal welding to form a composition plate, repeating the operation to obtain two composition plates with the same specification, cleaning and coating an isolating agent; (2) the base material surfaces of the two composition boards are aligned and then stacked, then vacuum welding is conducted on the joint surfaces, and a composite blank is obtained; (3) heating the composite blank; (4) rolling the composite blank to obtain a composite steel plate; (5) the composite steel plate is subjected to water cooling after rolling, and then the steel plate is straightened and air-cooled to the room temperature; (6) cutting and separating two thick stainless steel
