Pyrometer Method For Measuring Slab Temperature In A Reheat Furnace
US Patent:
4432657, Feb 21, 1984
Filed:
Mar 26, 1982
Appl. No.:
6/362346
Inventors:

US Classification:
374126
Abstract:
A method and apparatus to measure the temperature of a slab in a reheat furnace with increased accuracy using either a single or dual pyrometer system through use of a multiplicity of temperature correction functions involving temperatures of slab and wall, distance between a pyrometer and the slab at which it is aimed, a ratio of air and fuel supplying the furnace heat and radiation interferences. The functions are chosen by a microprocessor in the system dependent on temperature differentials, emissivity setting of the pyrometer, target distance between pyrometer and slab, and air and fuel flow rates existing and fluctuating in the system.
