Pyrometer for temperature measurement of melts

Abstract

The paper describes a new approach to melt temperature measurements using fiber-optic pyrometer. An analytical review
of methods and means of measuring the temperature of hightemperature melts is done. Operational characteristics of
materials of covers for contact thermometry are given. It presents calculations and experimental results on the justification of the spectral characteristics of materials of the crucible emitter type model of blackbody. There is shown the design of the crucible. The results of full-scale tests of the proposed pyrometer for measuring the melt temperature in a quenching furnace at Omsk enterprise of JSC «Omsktransmash» are presented.
