Изобретение относитс к области металлургии стали, в частности к обработке металла порошкообразными материалами.This invention relates to the field of steel metallurgy, in particular to the processing of metal with powdered materials.
Известен способ ввода порошкообразных материалов в жидкий металл, заключаюшийс в подаче их в струе газа в струю металла во врем его выпуска из печи на участке печного желоба.There is a known method for introducing powdered materials into a liquid metal, which consists in supplying them in a gas jet to a metal jet during its discharge from the furnace at the site of the furnace chute.
Однако при таком способе низка эффективность усвоени порошкообразных материалов жидким металлом.However, with this method, the efficiency of the assimilation of powdery materials by liquid metal is low.
Целью изобретени вл етс устранение указанного недостатка.The aim of the invention is to eliminate this drawback.
Максимальна эффективность использовани порошкообразных материалов наблюдаетс при условии равномерного их распределени в объеме жидкого металла, что достигаетс за счет проникновени газо-порошковой струи в жидкий металл и обеспечени турбулентного движени в месте встречи двух потоков. Дл достижени поставленной цели порошкообразные материалы по предлагаемому способу ввод т в жидкий металл со скоростью 50-80 м/сек несколькими стру ми с диаметром их истечени 7-10 мм, направленными по отношению к металлу под углом 60-120°.The maximum efficiency of using powdered materials is observed under the condition of their uniform distribution in the volume of the liquid metal, which is achieved due to the penetration of the gas-powder jet into the liquid metal and ensuring turbulent motion at the meeting point of the two streams. To achieve this goal, the powdery materials according to the proposed method are introduced into the liquid metal at a speed of 50-80 m / s in several streams with a diameter of 7 to 10 mm, directed towards the metal at an angle of 60-120 °.
Согласно описываемому способу перед выпуском металла из печи на желоб устанавливаетс съемна крышка, в которую вмонтированы несколько сопел дл подачи в металл газо-порошковой смеси. Сопла устанавливаютс под углом 60-120° по отношению к продольной оси желоба и несколько выше уровн движуш,егос по желобу металла.According to the described method, before a metal is released from the furnace, a removable lid is installed on the chute, into which several nozzles are mounted to feed the gas-powder mixture into the metal. The nozzles are set at an angle of 60-120 ° with respect to the longitudinal axis of the chute and slightly higher than the level of the slide, along the metal channel.
От начала и до конца выпуска в металл вводитс со скоростью 50-80 м/сек порошкообразный материал в струе несуш,его газа. Указанные выше параметры газо-порошковойFrom the beginning to the end of the release, the powdered material is introduced into the metal at a speed of 50-80 m / s in the stream of its laying gas. The above parameters are gas powder
струи обуславливают проникновение последней в глубь потока жидкого металла, а турбулентное движение в месте встречи двух потоков обеспечивает равномерное распределение порошка в объеме жидкого металла.the jets cause the latter to penetrate deep into the flow of the liquid metal, and the turbulent motion at the meeting point of the two flows ensures an even distribution of the powder in the volume of the liquid metal.
