PROBLEM TO BE SOLVED: To provide a method for correcting a meandering of a slab in a heating furnace by which the meandering of the slab can easily be corrected in a short period of time. SOLUTION: In the method for correcting the meandering of the slab when the slab 12 is conveyed in the walking-beam type heating furnace 15, the difference between the upper surface height positions of respective eccentric wheels 45, 46 constituting an eccentric wheel group 47 causing the meandering of the slab 12, is obtained by actual measurement for every eccentric wheel group 47, and the meandering locus of the slab 12 is simulated based on the difference. When the measuring locus is in the out of the allowable range, the upper surface height positions of the eccentric wheels 45, 46 constituting at least one eccentric wheel group 47 are corrected. Then a process, in which the meandering locus of the slab 12 is simulated again by again obtaining the upper surface height positions of the respective eccentric wheels 45, 46 according to the corrected upper surface height positions, are repeatedly performed until the meandering locus of the slab 12 becomes the allowable range. Thus, the upper surface height positions of the eccentric wheels 45, 46 are adjusted based on the simulated result. COPYRIGHT: (C)2010,JPO&INPIT |
