Abstract
The application of modern systems theory has opened the way for solving complicated measuring problems. Thus, variables which are not directly measurable can be reconstructed from easily measurable variables by using Kalman filtering. The center temperature of a slab in a reheat furnace which is not directly measurable can be estimated from the measured surface temperature of the observed slab. Improved estimation of slab center temperatures would be valuable as part of a computer control system for a steel reheat furnace
