Description

создают микрозавесу между рабочей поверхностью блоков и шлаком, обеспечива  тем самым высокую стойкость футеровки сталеплавильного агрегата в шлаковой зоне.create a micro-curtain between the working surface of the blocks and the slag, thereby ensuring a high durability of the lining of the steel-smelting unit in the slag zone.

Подачу газа на поверхность рабочей зоны осуществл ют до начала процесса в конвертерах , т. е. до образовани  на ней плотной оплавленной корочки.The gas is supplied to the surface of the working area before the process starts in converters, i.e. before a dense melted crust forms on it.

Выход ш,ие из фурмы 3 кислород и природный газ создают мощные циркул ционные потоки металла в ванне конвертера и особенно в зоне футеровки, прилегающей непосредственно к соплам фурм 3, что приводит к быстрому размыву этой зоны и образованию  м. Через патрубок 8 подают окись углерода или природный газ, или природный газ в смеси с углекислым газом, или воздухом, или окисью углерода.Oxygen and natural gas from the tuyere 3 coming out of the tuyere 3 create powerful circulating metal flows in the converter bath and especially in the lining zone adjacent directly to the nozzles of the tuyeres 3, which leads to a rapid erosion of this zone and the formation of m. or natural gas, or natural gas mixed with carbon dioxide, or air, or carbon monoxide.

Образующиес  на рабочей поверхности блоков пузырьки восстановительного газа до их отрыва от рабочей поверхности блоков образуют тончайщую пленку, «надежно защищают эту зону от физического и химического разрущени  металлом.The bubbles of reducing gas that form on the working surface of the blocks, prior to their separation from the working surface of the blocks, form a very thin film that “reliably protects this zone from physical and chemical destruction by the metal.

Описываемый сталеплавильный конвертер позвол ет улучшить регулирование сталеплавильного процесса, расширить сортамент выплавл емых сталей и при этом существенно повысить стойкость футеровки конвертеров.The described steel-making converter allows to improve the regulation of the steel-smelting process, expand the range of steel produced and, at the same time, significantly increase the durability of the converter lining.

Предмет изобретени Subject invention

Сталеплавильный конвертер, содержащий корпус, огнеупорную футеровку и встроенные в днище фурмы, состо щие из двух коаксиальных труб с независимым подводом реагентов , отличающийс  тем, что, с целью улучшени  регулировани  сталеплавильного процесса и повыщени  стойкости футеровки, фурмы встроены в газопроницаемые огнеупорные блоки, герметично вмонтированные в футеровку и снабженные патрубками дл  подвода газа, а в зоне шлакового по са футеровка выполнена в виде кольцевого газопроницаемого огнеупорного блока, примыкающего к кольцевому газовому коллектору, имеющему патрубки подвода и отвода реагентов.A steelmaking converter comprising a housing, a refractory lining and built into the bottom of the tuyere, consisting of two coaxial pipes with an independent supply of reagents, characterized in that, in order to improve the control of the steelmaking process and increase the durability of the lining, the tuyeres are embedded in gas-permeable refractory blocks, hermetically insulated, and the fumes are built into the gas-permeable refractory blocks, and hermetically insulated, the tuyeres are built into the gas-permeable refractory blocks, hermetically insulated, and the tuyeres are built into the gas-permeable refractory blocks. in the lining and equipped with nozzles for the supply of gas, and in the zone of the slag, the lining is made in the form of an annular gas-permeable refractory block adjacent to the ring CB gas manifold having a reagent inlet and outlet tubes.
