A method for meandering control in a twin roll strip-casting apparatus is provided to remove instability of strip resulting from temperature and thickness variation by implementing correction control of the rolling mill and two pinch rolls. A method for meandering control in a twin roll strip-casting apparatus comprises a difference measuring step of measuring the difference between right and left thicknesses of a strip(1) before and after a rolling mill(2,3,4,5), a positioning step of measuring the location of the strip before and after the rolling mill, a thickness control step of PID(Proportional Integral Derivative)-controlling to make the thickness differences before and after the rolling mill equal, and a temperature difference control step of compensating the thickness control to make the advancing direction of the strip according to the strip location before and after the rolling mill the same as the discharge path line.
