MEASUREMENT DEVICE FOR DETERMINATION OF GAS MEDIUM TEMPERATURE DISTRIBUTION ABOVE CHARGE SURFACE IN BLAST FURNACE, BLAST FURNACE EQUIPPED WITH IT AND APPROPRIATE METHOD

摘要

FIELD: measurement equipment.;SUBSTANCE: measurement device for determination of gas medium temperature distribution above charge surface in a blast furnace, comprising at least one first measurement probe (10) for emission and reception of electromagnetic waves and at least one second measurement probe (11) for emission and reception of acoustic waves, at the same time the first and second measurement probes (10, 11) are connected with a processor (12) for processing of measurement results with capability of simultaneous detection of temperature-dependent deviation between measurement results produced by the first and second measurement probes (10, 11). Also a blast furnace is proposed, which comprises a measurement device, and the method to determine distribution of gas medium temperature above charge surface in the blast furnace.;EFFECT: invention provides for long-term service life under comparatively low costs for maintenance.;19 cl, 4 dwg
