A method of estimating thermal conditions of a hearth has been developed, by using boundary element method for thermal analysis and experimental regression analysis for optimization. This method can evaluate hearth conditions in a reasonable computing time and supply useful information, such as heat flux distribution and effective volume of a hearth, which are closely connected with the operation. The erosion line estimated by the method is in good agreement with the one measured by boring in the hearth of Mizushima No.1 blast furnace blown out in 1982. The solidified layer distribution is changed to a great extent by the operation which has an effect on the thermal load to a hearth. In order to make the operation stable and to protect hearth refractories, it is important to continually monitor and control the hearth condition.
