PROBLEM TO BE SOLVED: To properly manage a roll gap without causing an operational abnormality originating in erroneous setting of the roll gap, in adjusting the roll gap of a slab supporting roll by using a roll gap value measured by a roll gap measuring device.SOLUTION: There is provided a roll gap management method for a continuous casting machine, in which a roll gap is managed on the basis of a roll gap of each slab supporting roll 3 measured by a roll gap measuring device 6 that is disposed on a dummy bar 4. In the roll gap management method, a roll gap setting value of a slab supporting roll being a roll gap management object is set on the basis of a previous roll gap measurement value, measured by the roll gap measuring device, of three slab supporting rolls arranged continuously in a casting direction with the slab supporting roll being the roll gap management object in the center, and a preset roll gap reference value of each of the preset slab supporting rolls, and a roll gap is determined to be proper or not by comparing the roll gap setting value to a present roll gap measurement value of the slab supporting roll being the roll gap management object. |
