METHOD AND APPARATUS FOR CONTINUOUS COMPRESSION FORGING OF CONTINUOUSLY CAST STEEL

摘要

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: $ 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 ( DEG ) with respect to the flat surface of the anvil. An apparatus for continuous compression forging continuously cast steel (1) comprising: at least a pair of anvils (2a, 2b) for vertically holding the pass line of cast steel (1) drawn out from a mold for continuous casting and continuously compression-forging the final solidified region of the moving cast steel (1) by moving the anvils (2a, 2b) toward and away from each other; a frame (13); a slider (14); and links (14a, 13b), wherein either of said anvils (2a, 2b) is disposed within said frame (13) which has a port (13a) through which said cast steel (1) is introduced, another anvil (2a) is secured to said slider (14) which can be reciprocated along a sliding surface formed in said frame, and said frame (13) and said slider (14) are hung from a crank shaft (15) via said links (14a, 13b), said crank shaft (15) acting to move said anvils (2a, 2b) toward and away from each other.$
