Abstract

Винахід забезпечує можливість безперервної реєстрації робочих параметрів сигналів вимірювань, що застосовуються для керування процесом продування у металургійних ємностях. При цьому в способі експлуатації продувальної фурми це досягається за рахунок того, що за допомогою щонайменше одного розташованого в головці (4) фурми в зоні надзвукового сопла детектора або сенсора (9а, 9b) під час експлуатації продувальної фурми (2), зокрема під час процесу продування, в головці (4) фурми у щонайменше одного надзвукового сопла визначають і/або вимірюють щонайменше поточний вхідний тиск (p) газу (8) і за допомогою детектора або сенсора (9а, 9b) поточну вхідну температуру (T) газу (8), причому поточний вхідний тиск (p) газу (8) за допомогою динамічної адаптації тиску (p) на клапанній станції або тиску подачі газу (8), що подається до фурми (2), регулюють і встановлюють таким чином, що поточний вхідний тиск (p) газу (8) відповідає розрахунковому тиску (р) щонайменше одного надзвукового сопла, і одержані при цьому сигнали вимірювань під час експлуатації продувальної фурми (2) переважно онлайн передають в підключений до вказаного щонайменше одного детектора або сенсора (9а, 9b) пристрій обробки даних і/або керування процесом і готуються для керування експлуатацією продувальної фурми (2).The invention provides the possibility of continuous recording of the operating parameters of the measurement signals used to control the purging process in metallurgical tanks. In the method of operation of the blowing lance, this is achieved by the fact that by means of at least one located in the head (4) lance in the area of the supersonic nozzle of the detector or sensor (9a, 9b) during the operation of the lance (2), in particular during the process purging, at least one supersonic nozzle in the head (4) of the lance determines and / or measures at least the current inlet pressure (p) of the gas (8) and using the detector or sensor (9a, 9b) the current inlet temperature (T) of the gas (8) , with the current inlet pressure (p) of gas (8) for assistance the dynamic pressure (p) adaptation at the valve station or the gas supply pressure (8) supplied to the lance (2) is adjusted and adjusted so that the current inlet pressure (p) of the gas (8) corresponds to the calculated pressure (p) of at least one the supersonic nozzle, and the measurement signals obtained during the operation of the blowing lance (2) are preferably transmitted online to a data processing and / or process control device connected to said at least one detector or sensor (9a, 9b) and are prepared to control the operation of the blowing lance ( 2).
