Description

Изобретение относитс  к черной металлургии и предназначено дл  выплавки стали в металлургических агрегатах с интенсификацией ее продувкой ванны газообразным окислителем .The invention relates to ferrous metallurgy and is intended for smelting steel in metallurgical units with its intensification by blowing the bath with a gaseous oxidant.

Известен способ ввода порошкообразных материалов в жидкую фазу в струе газа-носител .A known method of introducing powdered materials into the liquid phase in a stream of carrier gas.

Однако по известному способу эффективное растворение и взаимодействие порошкообразных материалов с жидкой фазой ограничено во времени, так как по мере их поступлени  в локальную зону ванны происходит увеличение в зкости этой зоны, затрудн ющее диффузию порошкообразных реагентов в объем ванны.However, according to a known method, the effective dissolution and interaction of powdered materials with the liquid phase is limited in time, since as they enter the local zone of the bath, the viscosity of this zone increases, making it difficult for the powder reactants to diffuse into the bath volume.

Кроме того, локальна  зона быстро насыщаетс  порошкообразными материалами, и дальнейший их ввод сопровождаетс  образованием медленно раствор ющихс  конгломератов и резким усилением выноса материалов из ванны в атмосферу реактора или агрегата. Лимитирующей стадией усвоени  .материалов станов тс  процессы массе- и теплообмена между локальной зоной ввода материалов и остальным объемом ванны. Эти  влени  вынуждают прекратить вдувание порошкообразных материалов, и суммарна  производительность их подачи в ванну резко снижаетс . Дл  интенсификации ассимил ции порошкообразных материалов жидкой фазой предлагаетс  способ, по которому вдувание лорошкообразных реагентов осуществл ют периодически до по влени  выноса извести в атмосферу , а в промежутках между вдувани ми производ т подачу в металл или на его поверхность газообразных реагентов до получени  гомогенного шлака.In addition, the local zone is quickly saturated with powdered materials, and their further entry is accompanied by the formation of slowly dissolving conglomerates and a sharp increase in the removal of materials from the bath into the atmosphere of the reactor or unit. The limiting stage of assimilation of materials becomes the processes of mass and heat exchange between the local zone of input materials and the rest of the volume of the bath. These phenomena make it necessary to stop the injection of powdered materials, and the total capacity of their feeding into the bath decreases sharply. In order to intensify the assimilation of powdery materials by the liquid phase, a method is proposed in which the injection of lorosca-like reagents is carried out periodically until lime is released into the atmosphere, and in the intervals between the injection gaseous reagents are supplied to the metal until homogeneous slag is obtained.

При вводе порошкообразных материалов по описываемому способу улучшаетс  их использование и уменьшаетс  их вынос. Кроме тогоWhen powdered materials are introduced by the described method, their use is improved and their removal is reduced. Besides

описываемый способ обеспечивает высокую интенсивность и максимальную лроизводительность ввода порошкообразных материалов в струе газа-носител  с получением оптимальных технологических параметров.The described method provides high intensity and maximum productivity of the introduction of powdered materials in the carrier gas stream with obtaining optimal process parameters.

Предмет изобретени Subject invention

Способ ввода порошкообразных материалов в жидкую фазу в струю газа-носител , отличающийс  тем, что, с целью интенсифнкаНИИ ассимил ции порошкообразных материалов жидкой фазой, вдувание их осуществл ют периодически до по влени  выноса извести в атмосферу, а в промежутках между вду3 вани мй порошкообразных материалов производ т подачу в металл или на его поверх4 ность газообразных реагентов до получени  гомогенного шлака.The method of introducing powdered materials into the liquid phase into a jet of carrier gas, characterized in that, in order to intensify the assimilation of powdered materials by the liquid phase, they are blown in periodically until lime is released into the atmosphere, and between the injections of powdered materials gaseous reactants are supplied to the metal or to its surface to obtain a homogeneous slag.
