Abstract

Изобретение относится к черной металлургии, точнее к производству стали. В способе предложено пропускать поток стали, переливаемый из металлоплавильного агрегата в ковш, внутри канала и в процессе этого пропускания подавать в поток металла раскислители, десульфураторы и другие модифицирующие элементы, изменяющие химический состав металла в ковше. Подачу осуществляют путем свободного падения, шнеком и инжекцией газа. Во всех примерах применяют нейтральный или инертный газ. Подачу элементов осуществляют в начале канала, в том числе на нескольких участках по периметру. Подачу элементов осуществляют на нескольких участках по высоте и периметру канала. Предложено осуществлять смену участков подачи элементов и в процессе смены производить смену ковша. Элементы подают в измельченном и/или гранулированном состояниях. Комплекс оборудования для осуществления способа содержит, наряду с металлоплавильным агрегатом, ковшом и системой нормированной подачи элементов, устройство, содержащее канал, рабочая часть которого выполнена из огнеупорного материала, в частности графита, при этом в процессе переливания стали устройство расположено между выпускным отверстием металлоплавильного агрегата и ковшом, при этом при указанном расположении устройства продольные оси канала и выпускного отверстия соосны. Устройство имеет привод перемещения, или самоустанавливается, или закреплено стационарно. Устройство содержит несущую конструкцию и сменную каналосодержащую часть. Последняя выполнена из графита. Канал имеет коническую форму на входе и цилиндрическую на остальном протяжении, при этом угол наклона конической поверхности отThe invention relates to ferrous metallurgy, more precisely to the production of steel. In the method, it is proposed to pass a stream of steel, poured from a metal-smelting unit into the ladle, inside the channel, and in the process of this transmission, deoxidizing agents, desulfuriators and other modifying elements that change the chemical composition of the metal in the ladle are supplied to the metal stream. The flow is carried out by free fall, auger and gas injection. All examples use a neutral or inert gas. The elements are fed at the beginning of the channel, including at several sites along the perimeter. The elements are supplied in several sections along the height and perimeter of the channel. It is proposed to carry out the change of sections of the supply of elements and in the process of changing to change the bucket. The elements are served in crushed and / or granular states. The complex of equipment for carrying out the method contains, along with a metal-smelting unit, a bucket and a system of normalized feeding of elements, a device containing a channel, the working part of which is made of refractory material, in particular graphite, while in the process of steel overflow the device is located between the outlet of the metal-smelting unit and bucket, while at the specified location of the device, the longitudinal axis of the channel and the outlet are coaxial. The device has a displacement drive, or is self-installing, or fixed permanently. The device contains a supporting structure and a removable channel-containing part. The latter is made of graphite. The channel has a conical shape at the entrance and a cylindrical shape for the rest of the length, with the angle of inclination of the conical surface from
