Description
кислителей. При этом в раскисл емом расплаве концентраци кислорода цонижаетс , а попадаемый в этот расплав кислород св зываетс с элементом-раскислителем, образу окисцую фазу. Равцовесные копцептрации раствореииого кислорода в раскисл юплем расплаве значительно ниже, чем в раскисл емом расплаве, поэтому процесс раскислени прекратитс лишь тогда, когда выравн ютс концентрации кислорода в раскисл ющем и раскисл емом расплавах .acidifiers. In this case, the oxygen concentration in the deoxidized melt decreases and the oxygen that enters this melt is bound to the deoxidizing element, forming the oxidation phase. Equal-weight co-grating of the solution of oxygen in the melt melting process is significantly lower than in the deoxidized melt; therefore, the deoxidation process is stopped only when the oxygen concentrations in the deoxidizing and deoxidized melts are equalized.
Пример. В нечи Таммана в корундовом тигле расплавили 500 г восстановленного водородом железа и раскислили его алюминием. В пробирку из двуокиси циркони , стабилизированной окисью иттри , поместили 10 г нераскисленного восстановленного водородом железа, содержащего 0,17% кислорода. При температуре 1600°С пробирку с нераскисленным железом погрузили в расплав раскисленного железа и выдержали некоторое врем . Во врем выдержки кислород из нераскислснного расилава через стенку пробирки из двуокиси циркони (проницаема дл кислорода мембрана)-диффундировал в раскисленный расплав. После выдержки пробирки извлекали и в полученных образцах определ ли содержание кислорода методом вакуу мдлавлени на эксхалографе «Бальцерс . В результате анализа оказалось, что содержание кислорода в образцах послеExample. In Tamman's nech, 500 g of hydrogen reduced iron were melted in a corundum crucible and deoxidized with aluminum. In a test tube of zirconium dioxide stabilized with yttria oxide, 10 g of non-acidified hydrogen reduced iron containing 0.17% oxygen was placed. At a temperature of 1600 ° C, the tube with unoxidized iron was immersed in the melted iron melt and held for some time. During the exposure, the oxygen from the unsalted rasilav through the wall of the zirconia tube (oxygen permeable membrane) diffused into the deoxidized melt. After holding the tubes, the tubes were removed and the oxygen content in the obtained samples was determined by the vacuum method using a Balzers exhalograph. As a result of the analysis, it turned out that the oxygen content in the samples after
выдержки 6 мин понизилось до 0,06%, при выдержке 30 мин - до 0,01%.extracts of 6 minutes decreased to 0.06%, while holding 30 minutes to 0.01%.
Таким образом, в результате диффузии кислорода через мембрану из двуокиси циркони произошло раскисление расплава железа.Thus, as a result of the diffusion of oxygen through a zirconia membrane, iron melt is deoxidized.
Использование в промышленности предлагаемого способа раскислени позвол ет иолучать металл чистый по неметаллическим включени м с минимальными количествами вредных примесей, что особенно важно дл прецизионных сплавов.The use in industry of the proposed deacidification method allows the metal to be cleaned by non-metallic inclusions with minimal amounts of harmful impurities, which is especially important for precision alloys.
