METHOD OF GUIDING STEEL IN ROLLING OF GUIDE RAIL FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To lower the temperature of steel in a rolling process and to make it possible to perform continuous rolling by stable guidance. SOLUTION: During a step of rolling the steel with a rolling mill and in a process where the rolling is performed by changing the rolling direction by twisting the steel at least once, by guiding the steel to rolling rolls through an inlet roller guide G2, rolling it while performing twist guidance of the steel S5 with an outlet twist roller guide G1 and guiding a twist-rolled steel S6 with an outlet roller guide G3, the continuous rolling can be performed.
