Keywords:

New direction of multicolour symmetric-wave pyrometry is developed. It significantly increases metrological characteristics and widens application field of the most efficient continuous lightguide and contactless temperature control of metal alloys. Regularities of multicolour thermometry and metal alloys optical characteristics influence on errors of method of linear symmetric-wave
thermometry are studied. Using established regularities, on the base of modern optoelectronic, fiber and microprocessor technologies, algorithms, methods and means of symmetric-wave thermometry were developed. Modernization of continuous temperature control on the base of symmetric-wave pyrometry decreases errors of method of such temperature control in 2,3; 4,9–
13,2 and 3,1–3,6 times comparing with the known multicolour, as well as classical energy and spectral ratio thermometry, respectively.
