Description

Изобретение относитс к металлургии черных металлов и может быть использовано при обработке чугуна и стали жидкими шлаками.The invention relates to the metallurgy of ferrous metals and can be used in the processing of iron and steel by liquid slags.
Известен способ десульфурации шлака за счет продувки шлака кислородом и топливом с добавками через концентрические трубы. Однако этот процесс требует сложного оборудовани в случае применени шлака дл рафинировани и дополнительного нагрева.The known method of desulfurization of slag by blowing slag with oxygen and fuel with additives through concentric tubes. However, this process requires sophisticated equipment when slag is used for refining and additional heating.
С целью увеличени скорости десульфурации по предложенному способу жидкий шлак продувают смесью топлива с теплотворной способностью 5000-9000 ккал/кг и кислорода в соотношении 1:2-1:4 на глубине /&-V4 от высоты сло шлака. При этом удаление серы из шлака происходит за счет ее взаимодействи с парами воды и кислородом факела . Погружение горелки в шлак способствует его перемешиванию, что в большой мере ускор ет процесс десульфурации. Дл окислени серы расход кислорода устанавливают выше стехиометрически необходимого дл сгорани топлива. Дл лучшего контакта факела с серой головка горелки выполн етс многосопловой . Нагретый доменный шлак с низким содержанием серы используют дл обессеривани металла в ковшах в процессе их выпуска или при разливке стали в изложницы.In order to increase the desulfurization rate of the proposed method, liquid slag is blown with a mixture of fuel with a calorific value of 5000-9000 kcal / kg and oxygen in a ratio of 1: 2-1: 4 at a depth of & & V4 from the height of the slag layer. In this case, the removal of sulfur from the slag occurs due to its interaction with water vapor and oxygen of the flame. Immersion of the burner in the slag promotes its mixing, which greatly accelerates the desulfurization process. For the oxidation of sulfur, the oxygen consumption is set higher than the stoichiometrically necessary for the combustion of fuel. For better contact of the torch with the gray burner head, multi-nozzle is made. Heated blast furnace slag with a low sulfur content is used to desulfurize the metal in the ladles during their production or when casting steel into molds.
