Description
Предлагаемый способ относитс к области выплавки стали в качающихс мартеновских печах иа жидкой завалке с продувкой ваины воздухом , обогащенным кислородом.The proposed method relates to the field of steel smelting in swinging open-hearth furnaces and a liquid filling with the wane blown with oxygen-enriched air.
По существующей технологии выплавки стали в качающихс печах из щихты, содержащей высокий процент жидкого чугуна, в завалку и по ходу плавки даетс большое количество холодпых сыпучих материалов, руды и флюсов. При этом удлин етс врем завалки, прогрева, плавлени и фришевани шихты и снижаетс производительность печи. Кроме того, во врем завалки сыпучих материалов не может производитьс продувка металла кислородом или обогащенным воздухом, что также снижает возможную эффективность применени кислорода.According to the existing technology of steel smelting in rocking furnaces from pulpit containing a high percentage of liquid iron, a large amount of cold granular materials, ore and fluxes is supplied to the filling and along the smelting process. At the same time, the time of filling, warming up, melting and freezing of the charge is prolonged and the productivity of the furnace decreases. In addition, during the filling of bulk materials, the metal cannot be flushed with oxygen or enriched air, which also reduces the possible efficiency of oxygen use.
С целью интенсификации работы качающихс мартеновских печей и максимального повышени времени использовани кислорода, предлагаетс следующий способ ведени плавки.In order to intensify the operation of the swinging open-hearth furnaces and maximize the use of oxygen, the following method of smelting is proposed.
Процесс ведетс непрерывно с частичным опорожнением печи. После выпуска в печь заливают жидкий чугун в количестве до 100% всей металлической щихты. Фришевание ванньГпроизводитс кислородом или обогащенным воздухом, вдуваемым в жидкий металл. Присадка метал . лического лома или железной руды может производитьс после окончани заливки чугуна, в зависимости от хода продувки, с целью понижени температуры ванны и предотвращени оплавлени футеровки.The process is conducted continuously with partial emptying of the furnace. After being released, molten iron is poured into the furnace in an amount up to 100% of all metal scum. The bathing is made by oxygen or enriched with air blown into the liquid metal. Additive metal. scrap or iron ore can be produced after cast iron is finished, depending on the purge process, in order to lower the bath temperature and to prevent the lining from melting.
