A method for cutting a roller steel top in a rolling process is provided to improve normal product recovery ratio by cutting the roller steel top discharged from a roughing mill into the size approximate to the preset size. A method for cutting a roller steel top in a rolling process, comprises a step of taking, as an input, pulse value of a pulse generator for operating a driving gear for roughing mill process; a step(S1) of setting a rolled steel top cut length value to a minimum value, as a variable for a formula for calculating pulse values from the rolled steel outlet time sensed by a rolled steel sensor to the operation of a cutter; a step(S3) of setting a predetermined value for decreasing the distance from the rolled steel sensor to the cutter; a step(S5) of calculating a cutter operation pulse value by applying the set value to the formula of the step(S1); a step(9) of performing roughing milling process and taking, as an input, pulse signal of the pulse generator for operating the driving gear; and a step(S13) of counting pulse signals generated since sensing of the rolled steel sensor, and operating the cutter if the counted pulse signals reach the calculated pulse values. |
