Description
ческий монолит, около 82% массы которого составл ет масса дроби, а около 18% - масса алюмини .a monolithic monolith, about 82% of the mass of which is the mass of the fraction, and about 18% is the mass of aluminum.
В процессе заливки формы сталью и после нее стержень прогреваетс , а алюминий (или его сплав) разм гчаетс и расплавл етс . В результате этого металлический стержень становитс податливым, т.е. не преп тствует усадке полой стальной отливки и, следовательно, предотвращает образование гор чих трещин на внутренней полости слитка.In the process of pouring the mold with steel and after it, the core is heated, and aluminum (or its alloy) is softened and melted. As a result, the metal rod becomes pliable, i.e. does not prevent the shrinkage of the hollow steel casting and, therefore, prevents the formation of hot cracks in the inner cavity of the ingot.
Формул а изобретени Способ получени полого слитка при заливке сверху, включающий последовательную простановку на поддон, имеющий закрытую емкость дл приема расплавл емого металла стержн , состо щего из тугоплавкой и легкоплавкой частей, изложницы, прибыльной надставки и заливочного устройства , заливку металла в изложницу, кри- SUMMARY OF THE INVENTION A method for producing a hollow ingot when casting from above, comprising sequentially placing it on a pallet having a closed container for receiving a molten metal rod, consisting of refractory and low-melting parts, a mold, a profitable extension and a casting device, pouring metal into a mold,
сталлизацию слитка и извлечение его из изложницы , отличающийс тем, что, с целью повышени качества слитка и экономичности процесса, стержень используют предварительно изготовленным путем нагрева до расплавлени легкоплавкой части и распределени по-ему объему части тугоплавкого материала, вз того в виде гранул .the metallization of the ingot and its extraction from the mold, characterized in that, in order to improve the quality of the ingot and the efficiency of the process, the rod is used pre-made by heating to melt the low-melting part and distributing in some volume part of the refractory material, in the form of granules.
