Contactless thermometric system (CTS)
The CТS is purposed for the technical realization of continuous distant temperature measurement, registration and regulation technologies in foundry, metallurgy, ceramic, glass and other industries. For example, it can be used for continuous temperature measurement of liquid metal in a stream or flow during tapping from metallurgical furnaces and aggregates, as well as the slab under mold in a continuous casting machine; metal sheet, strip or wire.
2. Operation principle
It is based on the contactless radiation pyrometry of the controlled surface in zones and spectrum ranges with the most stable emissivity (ε) and transmissivity (τ), with the following processing of primary pyrometric information in accordance with the algorithms of multicolour, for example, symmetric-wave thermometry (SWT), eliminating influence of ε and τ.
3. Main tеchnical characteristics
|Range of measuring temperatures, ºС
|Measurement error, %
Measurement errors of known solutions, including the classical energy and spectral ratio radiation pyrometry, reach 10 percent or more under conditions of metallurgical production. This, at best, limits or completely excludes their practical use. The measurement errors of the CTS with SWT-algorithm are smaller than the classical energy, spectral ratio and the known multicolour thermometry ones in 4,9–13,2; 3,1–3,6 and 2,3 times, respectively.
5. Теchnical-economic efficiency
CTS provides non-alternative continuous temperature control and optimal operation of the technological processes temperature regimes. Due to this fact, it is possible to obtain products with determined properties at the minimally possible resource and energy expenses. For example, in the case of electric arc and cupola furnaces, such temperature control reduces the coke consumption on 6-10 %, electricity on 15-20 %, increases the lining life duration on 25-35 %, reduces the waste of charge materials (environmental pollution) on 5-30 % and spoilage “due to the temperature” on 20-70 %.
