Пример. Осуществл ют способ на кислородном конверторе емкостью 130 т. Расход вдуваемого в ванну кислорода составл ет в насто щее врем 450 . максимально допустимый нагрев воды в подъемном экранированном газоходе над конвертором, наход щейс под давлением 12 атм,- 185°С. В соответствии с предложением расход кислорода в начальный период продувки увеличивают до 670-900 до достижени температуры воды в подъемном газоходе 163-176°С. При дальнейшем ходе продувки отклонение существующей в данный момент величины нагрева воды до уровн 163-176°С вл етс импульсом дл регулировани расхода дутьевого кислорода. Регулирование осуществл етс путем изменени положений клапана расхода кислорода с помощью исполнительного механизма до тех пор, пока отклонение величины нагрева от уровн 163-176°С не будет сведено к нулю.Example. The method is carried out on an oxygen converter with a capacity of 130 tons. The flow rate of oxygen being blown into the bath is currently 450. The maximum allowable heating of water in a shielded lifting gas duct above the converter under a pressure of 12 atm is 185 ° C. In accordance with the proposal, the oxygen consumption in the initial period of purging is increased to 670-900 until the water temperature in the lifting duct reaches 163-176 ° C. With further purging, the deviation of the currently existing amount of water heating to the level of 163-176 ° C is an impulse for controlling the flow of blast oxygen. Regulation is accomplished by changing the positions of the oxygen flow valve using an actuator until the deviation of the heating value from the level of 163-176 ° C is reduced to zero.
Таким образом, описанный способ продувки позвол ет подн ть среднюю интенсивность продувки за плавку на 20-30% с соответствующим сокращением продолжительности продувки и ростом производительности агрегата .Thus, the described purge method allows to increase the average purge rate for melting by 20-30% with a corresponding reduction in the purge duration and an increase in the productivity of the unit.
Предмет изобретени Subject invention
Способ продувки металла в конверторе с регулированием расхода кислорода, отличающийс тем, что, с целью интенсификации процесса продувки, в течение первых 10- 60 сек продувку ведут с расходом кислорода, в 1,5-2,0 раза превыщающим номинальный, а в остальное врем продувки расход кислорода регулируют по температуре воды в холодильниках газохода, поддержива ее в пределах величин, на меньщпх максимально допустимого значени .The method of purging the metal in the converter with the regulation of oxygen consumption, characterized in that, in order to intensify the process of purging, during the first 10- 60 sec. The purge oxygen flow rate is controlled by the temperature of the water in the flue gas coolers, keeping it within the limits of values, at less than the maximum permissible value.
