Description
Изобретение относитс к металлургии черных металлов и может быть использовано при производстве стали.This invention relates to ferrous metallurgy and can be used in steel making.
Известен способ рафинировани стали в ковше шлаками с применением образуюш,их газы флюсов (кальцинированной соды, поваренной соли).There is a method of refining steel in a ladle with slags using forms, their gases fluxes (soda ash, table salt).
Недостатком известного способа вл етс необходимость тщательной подготовки и хранени примен емых материалов из-за их гигроскопичности, а также установки мощных выт жных устройств, так как выдел ющиес газы вл ютс токсичными.The disadvantage of this method is the need for thorough preparation and storage of the materials used because of their hygroscopicity, as well as the installation of powerful exhaust devices, since the evolved gases are toxic.
С целью интенсификации процесса по предлагаемому способу при выпуске металла в ковш с жидким синтетическим шлаком ввод т металлический цинк в количестве 0,15- 0,30 кг на 1 т стали. Возможно введение металлического пинка одновременно с твердой шлакообразующей смесью.In order to intensify the process according to the proposed method, with the release of metal into the ladle with liquid synthetic slag, metallic zinc is introduced in an amount of 0.15-0.30 kg per 1 ton of steel. It is possible to introduce a metallic kick simultaneously with a solid slag-forming mixture.
При введении металлического цинка под действием выдел ющихс паров металл в ковше энергично перемешиваетс и рафинируетс .With the introduction of metallic zinc under the action of evolving vapors, the metal in the ladle is vigorously stirred and refined.
Выбор цинка, как газифицирующего реагента , объ сн етс тем, что цинк нетоксичен, имеет небольшой атомный вес (65,38), сравнительно низкую температуру плавлени (419°С) и кипени (906°С). Удельный вес цинка несколько выше (7,13), чем удельный вес жидкой стали (6,92), что позвол ет рафинировать парами цинка всю толщу наход щегос в ковше металла.The choice of zinc as a gasifying agent is due to the fact that zinc is non-toxic, has a small atomic weight (65.38), a relatively low melting point (419 ° C) and boiling point (906 ° C). The specific gravity of zinc is somewhat higher (7.13) than the specific gravity of liquid steel (6.92), which allows the entire thickness of the metal in the ladle to be refined with zinc vapor.
