The invention belongs to the technical field of steel, and particularly relates to a method for producing hot-rolled thin-specification 600 MPa compartment steel based on ESP total head-free thin slabcontinuous casting and continuous rolling process, and belongs to the category of the low-energy-consumption green manufacturing technology. According to the technology process, a casting blank is directly rolled without heating of a soaking pit at the high pulling rate, the production technology process is short, energy is saved, and cost is reduced. Thin-specification hot-rolled high-strength steel of 1.2 mm-3.5 mm can be stably rolled and produced, a hot-rolled roll is uniform in thickness in the whole length direction, and the performance is stable. According to the product performance, the yield strength Rp0.2 is larger than or equal to 600 MPa, the tensile strength Rm is 650-830 MPa, A is larger than or equal to 15%, and metallographic structures are ferrite and a small amount of granular bainite.
