    摘要： Provided is a method of controlling operation of a tandem rolling mill which enables large reduction rolling in the latter-stage stand of the tandem rolling mill necessary for manufacturing fine-grained steel, and so on. The method comprises: a step of determining a first exit-side sheet thickness in rolling a constant portion of a material to be rolled; and a step of determining a second exit-side sheet thickness in rolling a front end portion of the material, such that a pre-tightening load becomes a set value or less; the material is rolled into the second exit-side sheet thickness, until the front end portion is fed into the stands; the constant portion is rolled by the stand given a pre-tightening load into the first exit-side sheet thickness; and the second exit-side sheet thicknesses of the stands given the pre-tightening load are made larger than the first exit-side sheet thickness.

    摘要： Guide roller units are made movable back and forth in the direction of thickness of a slab, allowing slab lagging covers to be inserted to and withdrawn from gaps formed between the guide roller units and the slab. Depending on the casting speed, those ones of the guide roller units and the slab lagging covers which are in proper positions are replaced from one to the other for selective use so that the respective lengths of a cooling zone and a heat keeping zone are adjusted to control the cooling rate of the slab in a positive manner. The slab temperature can be kept at a value capable of carrying out rolling regardless of change in the casting speed depending on variations in the amount of molten steel supplied.
