The invention discloses a method for representing the pressing degree of a hot-rolled plate oxidized iron sheet. The method comprises the following steps that a pressing degree index of the oxidized iron sheet is used, the pressing degree index of the oxidized iron sheet is equal to the quotient between the total depth of pockmarks formed in the surface of a hot-rolled sample plate and the thickness of the hot-rolled sample plate, wherein the total thickness of the pockmarks is the sum of the thicknesses of all pockmark formed in the surface of the hot-rolled sample plate. The method for representing the pressing degree of the hot-rolled plate oxidized iron sheet fills up the blank that a method used for evaluating the pressing severity of the oxidized iron sheet of the hot-rolled plate does not exist in the prior art.
