Description
(54) СПОСОБ ОБРАБОТКИ МЕТАЛЛА ГАЗАМИ(54) METAL TREATMENT METHOD FOR GASES
1one
Изобретение относитс к области металлургии и может быть использовано при выплавке и разливке, например электротехнических и легированных сталей и сплавов.The invention relates to the field of metallurgy and can be used in the smelting and casting of, for example, electrical and alloyed steels and alloys.
Известен способ обработки жидкого металла газами в сталеплавильной печи, например электродуговой, путем их подачи последовательно через трубопровод, один или несколько расположенных на поверхности металла пористых огнеупоров.There is a method of treating a liquid metal with gases in a steel-smelting furnace, such as an electric arc furnace, by feeding them successively through a pipeline, one or more porous refractories located on the metal surface.
С целью сокращени времени обработки металла в печи и ускорени протекани реакций по предлагаемому способу пористые огнеупоры заглубл ют в металл на величину, равную 0,,75 их высоты, и продувку через них ведут с одновременным возвратно-поступательным перемещением в горизонтальной плоскости со скоростью 10-35 м/мин в секторе 60-90°.In order to reduce the processing time of the metal in the furnace and accelerate the reactions carried out according to the proposed method, porous refractories are embedded in the metal by an amount equal to 0, 75 of their height, and blowing through them is carried out with simultaneous reciprocating movement in the horizontal plane at a rate of 10- 35 m / min in the sector of 60-90 °.
Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.
при выплавке стали 16Г2САФ в 100-т дуговой печи два огнеупора с удельным весом 4 г/см (при удельном весе жидкого шлака 3,7 г/см), имеющие газонепроницаемую поверхность за исключением поверхности, соприкасающейс с жидким расплавом, соедин ют посредством штуцера с азотопроводом и задают на зеркало ванны. Путем перемещени огнеупоров по поверхности ваииы с помощью трубопровода возвратно-пс/стунательно со скоростью 12 м/мкн ;з се чторе 20 производ т легирован е азотом всего объема металла. После проведени обработки металла газом пористые элементы удал ют с поверхности ванны, осматривают и испо.чьзукгг дл последующих обработок. Раги-юмепмаи обработка всего металла азотом за 1склкг-1гнием так называемых «мертвых зол (.:ок(:;1щает врем легпрозани стали 16Г2САФ азотом в печи на 80 мин; азот ввод т в распла; через трубки диаметром -.i дюйма.when smelting steel 16G2SAF in a 100-t arc furnace, two refractories with a specific weight of 4 g / cm (with a specific weight of liquid slag 3.7 g / cm), having a gas-tight surface with the exception of the surface in contact with the liquid melt, are connected with nitrogen line and set on the mirror bath. By moving refractories over the surface of the vacuum using a return-ps / piping pipeline at a speed of 12 m / µm, after all 20, the entire volume of the metal is doped with nitrogen. After the metal has been treated with gas, the porous elements are removed from the surface of the bath, inspected and used in a bit-round for subsequent treatments. Ragi-umepmai treatment of the whole metal with nitrogen for 1klkg-1 with the help of the so-called "dead ashes" (.: Ok (:: 1) the time of light shrinking of 16G2SAF steel with nitrogen in the furnace for 80 minutes; nitrogen is introduced into the melt;
