Abstract

Recently requests for high added value steel products have been increased to produce vehicles. Since strip temperature in hot strip mills is one of the most important factors to determine the material properties, temperature control on Run Out Table (ROT) is crucial. In conventionally used temperature model, running steel strip is divided into segments of the same length, and then strip temperature is calculated for each segment. In this paper, we propose a new temperature model in which area of ROT is divided into sections fixed in space and strip temperature is calculated in each section. The proposed model is considered to be useful for model-based design of the temperature control since positional relation between cooling valves, i.e. control inputs and sections can be invariant. The validity of the proposed model is confirmed by numerical simulations.
