<p>The present invention provides a method for controlling the carrying-in of metallic materials in a walking beam heat treatment furnace, by which heat treatment can be efficiently performed on metallic materials having various lengths in an anteroposterior direction. A control unit (18) calculates Xn+1 determined by Xn+1 = (Xn+mL)-{(an/2)+D+(an+1/2)} from the length (an) in the anteroposterior direction of an n-th metallic material (Wn), the distance (Xn) between a reference position (B) and the center position of the n-th metallic material (Wn), and the length (an+1) in the anteroposterior direction of an (n+1)-th metallic material (Wn+1) to be disposed next on a stationary beam (16), and when Xn+1 = (an+1/2), disposes the (n+1)-th metallic material (Wn+1) at Xn+1 by means of a carrying-in device (14) while a moving beam (17) is stopped, and when Xn+1 n+1/2), operates the moving beam (17) m times until Xn+1 = (an+1/2) is achieved.</p> |
