ROLLING METHOD FOR ROD-SHAPED ROLLING STOCK PARTICULARLY SUCH AS ROD STEEL AND WIRE

摘要

PURPOSE: A rolling method for a bar-shaped rolling stock is provided to rapidly act and to control the short difficulty. CONSTITUTION: The method for rolling a bar-shaped roll stock particularly such as a bar steel and a wire includes the steps of:controlling the work roll through an oil-pressure cylinder unit; measuring the practical roll power; measuring the roll gap spring-back caused by the roll power with the help of the practical roll power; deciding the roll control calibrating value with the help of a certain roll gap and the roll gap spring-back to make the practical roll gap approach a specific roll gap; and changing the roll control value within the stand control time by the roll control calibrating value.
