Description
Изобретение относитс к черной металлургии , в частности к рафинированию л идких металлов в конверторе или мартеновской печи .The invention relates to ferrous metallurgy, in particular to the refining of liquid metals in a converter or an open-hearth furnace.
Известны способы обработки металлов с целью их нагрева и рафинировани топливнокислородным факелом при недостатке или избытке кислорода относительно необходимого дл полного сгорани .Methods are known for treating metals with the aim of heating and refining them with an oxy-fuel flame with a lack or excess of oxygen relative to that required for complete combustion.
При этом наблЕОдаетс лереход значительного количества вредных примесей (нанример, серы) из топлива в металл.In this case, a significant amount of harmful impurities (nanorimers, sulfur) from fuel to metal is transferred.
Целью изобретени вл етс исключение загр знени металла вредными Нримес ми даже при значительном содержании их в топливе.The aim of the invention is the elimination of metal contamination by harmful impurities even with their considerable content in the fuel.
Дл этого тонливо ввод т в агрегат внутри струи кислорода, причем избыток последнего относительно необходимого дл полного сгорани топлива нодаерживают в пределах 150-1000%.For this, a unit is internally introduced into the unit inside the oxygen jet, and the excess of the latter relative to that required for complete combustion of the fuel is kept in the range of 150-1000%.
В качестве топлива используют углеродистое жидкое топливо, на пример .нефть или :каменмоугольный деготь. Фурму располагают на таком рассто нии от металла, чтобы топливо успело полностью сгореть до соприкосновени струи с шихтой. Carbonic liquid fuel is used as a fuel, for example, oil or: coal tar. The lance is located at such a distance from the metal that the fuel has time to completely burn before the jet comes in contact with the charge.
Изменение процента избытка кислорода позвол ет получить металл с заданной температурой при переменном количестве скрапа.A change in the percentage of excess oxygen yields a metal with a given temperature with a variable amount of scrap.
Использование нредлагаемого способа позвол ет , кроме того, снизить количество дыма.The use of the proposed method further reduces the amount of smoke.
Предмет изобретени Subject invention
Способ обработки металлов, включающий продувку металла топливно-кислородным факелом с избытком кислорода относительно необходимого дл полного сгорани топлива, о тл и ч а ю щ и и с тем, что, с целью исключени загр знени металла вредными примес ми топлива, топливо ввод т в агрегат внутри струи кислорода, избыток которого поддерживают в пределах 150-1000%.A method of treating metals, which involves purging the metal with an oxy-fuel torch with an excess of oxygen relative to that required for complete combustion of the fuel, about that, in order to prevent contamination of the metal with harmful impurities of fuel, the fuel is introduced into the unit inside the jet of oxygen, the excess of which is maintained in the range of 150-1000%.
