Изобретение относитс к черной металлургии , в частности к электрометаллургии комплексных модификаторов на основе редкоземельных металлов дл легировани и модифицировани сталей и сплавов.The invention relates to ferrous metallurgy, in particular, to electrometallurgy of complex modifiers based on rare-earth metals for alloying and modifying steels and alloys.
Введение редкоземельных металлов в сталь, сплавы черных и цветных металлов приводит к эффекту модифицировани , т. е. к улучшению структуры основного металла. При этом достигаетс рафинирование металлического расплава от вредных примесей (кислорода, азота, углерода и водорода), а также образование и удаление тугоплавких соединений с металлоидами.The introduction of rare earth metals into steel, alloys of ferrous and non-ferrous metals leads to the effect of modification, i.e., to an improvement in the structure of the base metal. This achieves the refining of the metal melt from harmful impurities (oxygen, nitrogen, carbon, and hydrogen), as well as the formation and removal of refractory compounds with metalloids.
Особенно эффективно вли ют редкоземельные металлы на сплавы железа, хрома, никел , ниоби . Это вли ние про вл етс в улучшении структуры поверхностной окисной пленки , что приводит к резкому возрастанию жаропрочности сплавов.Rare-earth metals are particularly effective in alloys of iron, chromium, nickel, and niobium. This effect is manifested in the improvement of the surface oxide film structure, which leads to a sharp increase in the heat resistance of the alloys.
Известен модификатор, содержащий 15- 70 вес. % редкоземельных металлов и (или) тори и 6-85 вес. % кремни , остальное примеси , железо (при добавлении сплава в чугун или сталь) или магний и (или) алюминий (при добавлении сплава в расплавы легких цветных металлов). Эти сплавы не должны содержать более 10 вес. ч. цери на 100 вес. ч. редкоземельных металлов и тори и иметь атомное соотношение кремни и редкоземельного металла с торием более 2:1.Known modifier containing 15- 70 weight. % rare earth metals and (or) thorium and 6-85 weight. % silicon, the rest of the impurities, iron (with the addition of an alloy in cast iron or steel) or magnesium and (or) aluminum (with the addition of an alloy in the melts of light non-ferrous metals). These alloys should not contain more than 10 weight. h cerium per 100 weight. including rare earth metals and thori and have an atomic ratio of silicon and rare earth metal with thorium more than 2: 1.
Иедостаток известного модификатора заключаетс в том, что высокое содержание кремни не позвол ет использовать его при легировании и. модифицировании низкокремнистых жаростойких и жаропрочных сталей, сплавов и других металлов. Вследствие малого удельного веса (5,2-4,4 см) и высокой температуры его плавлени (1600-1400°С) усвоение редкоземельных металлов при легировании чугуна и стали не превышает 30%. Предлагаемый модификатор отличаетс тем, что дл повышени использовани редкоземельных металлов он дополнительно содержит никель и его компоненты вз ты в следуюш,ем соотношении, вес. %:The disadvantage of the known modifier is that the high silicon content does not allow its use in doping and. modification of low-silicon heat-resistant and heat-resistant steels, alloys and other metals. Due to the low specific weight (5.2-4.4 cm) and the high temperature of its melting (1600-1400 ° C), the assimilation of rare-earth metals during the alloying of iron and steel does not exceed 30%. The proposed modifier is characterized in that in order to increase the use of rare earth metals, it additionally contains nickel and its components are taken in the following ratio, weight. %:
