FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular, to a method of determining moment of breakdown of heat insulation of air tuyere of blast furnace. Method involves determination of temperature difference of input and output water streams on tuyere with heat insulation and on at least one serial tuyere without heat insulation, installed on same manifold. Upon achieving difference of said temperatures on tuyere with heat insulation to values on serial tuyere and if difference of flow rates of input and output water streams, cooling tuyere with heat insulation, within measurement error, moment of replacement of tuyere with damaged insulation is detected.
EFFECT: use of invention enables to accurately determine moment of replacement of tuyere due to breakdown of its thermal insulation and provide safe operation of blast furnace.
