Abstract
A method of determining the conditions of heat transfer at the interface of the refractory and a metal shell of the furnace by calculating the interface temperature from thermoprobes in the refractory and then from a thermoprobe in the metal shell and the temperature of cooling water applied to the shell, and comparing these interface temperatures to determine whether a gap has formed between the refractory and shell and whether cooling of the shell is sufficient.
