ABSTRACT:
In controlling furnace temperature, a desired temperature profile of a slab in a direction along its movement through a furnace is calculated by using an expression for total fuel flow as a function of slab temperature and minimizing the total fuel flow. The present slab temperature is calculated by using the distribution of present gas temperatures in the furnace. The heating of the furnace is adjusted based on the temperature difference between the present slab temperature and a desired temperature.
