The characteristics of rolling deforming schedule on hot continuous rolling strip and the application on optimization method in this field are studied. The mathematical model of multi-object optimization for minimizing energy consumption balancing load and best profile on it is established. The problem of multi-object optimization is solved by fuzzy theory and method. With the example of a six-hot continuous rolling strip, the deforming schedule of the common rolling, the single-object optimization design and the multi-object fuzzy optimization design are compared with each other, thus proving the effectiveness of the method.
