ABSTRACT OF THE DISCLOSURE A method of continuous compression forging, with a compression forging anvil, the final solidified region of cast steel drawn out from a mold for continuously casting comprising the step of: compressing said cast steel with said anvil at a compressing cycle which meets the following conditions: Image where t: the compressing cycle (sec), .delta.: the overall thickness reduction, Vc: the casting speed (mm), D: the cast steel thickness before compression forging, .theta.: the inclination angle (°) with respect to the flat surface of the anvil. An apparatus for continuous compression forging continuously cast steel comprising: at least a pair of anvils for vertically holding the pass line of cast steel drawn out from a mold for continuous casting and continuously compression-forging the final solidified region of the moving cast steel by moving the anvils toward and away from each other; a frame; a slider; and links, wherein either of said anvils is disposed within said frame which has a port through which said cast steel is introduced, another anvil is secured to said slider which can be reciprocated along a sliding surface formed in said frame, and said frame and said slider are hung from a crank shaft via said links, said crank shaft acting to move said anvils toward and away from each other.
