Abstract

Abstract:

Considering at the difficulty that the temperature of slab in reheat furnace is immeasurable, an adaptive temperature prediction model based on state space of slab was established according to mechanism of heat transfer. The real time measurement information of slab temperature behind rough mill can be used to adaptively revise the temperature prediction model. Industry experiments and simulations indicate that this temperature prediction model of slab is of high precision, good adaptive ability and strong robustness.
