In steel manufacturing processes, it is extremely important to control the temperature of products for acquiring required quality. In order to precisely control the temperature of steel plates at water-cooling process after hotrolling, it is necessary to know correct values for heat transfer coefficients. Those coefficients, however, are functions of cooling conditions such as plate temperature and cooling water flux, and it is usually difficult to calculate them directly from operational data observable on site. In this paper, a new approach is presented to estimate heat transfer coefficients at water-cooling process of steel plates, by combining parameter search with simulated annealing method and heat transfer calculation. Basic evaluation of this approach is conducted by using actual operational data.
