Description
Добавки 10-20% азотированного феррохрома в брикет позвол ют производить легирование стали азотом в широком дпапазоне его копцентраций и сниз т термичность смеси (часть тепла будет расходоватьс на расплавление металлической составл ющей ). Растворение восстановленного титана и железа из ильменитового концентрата в азотированном феррохроме приведет к более полному восстановлению титана и образованию в сплаве нитридов титана, что увеличит усвоение азота и титана сталью и позволит модифицировать ими расплавленный металл. Введение азотированного феррохрома менее 10% ухудшит услови образовани нитридов тнтана и увеличит термичность смеси. При содержании азотированного феррохрома более 20% выделившегос тепла может не хватить на расплавление металлической части, что может привести к неравномерному распределению хрома в металле.Additives of 10–20% of nitrided ferrochrome into the briquette allow the steel to be alloyed with nitrogen over a wide range of its concentration and reduce the mixture termination (part of the heat will be spent on melting the metal component). The dissolution of reduced titanium and iron from the ilmenite concentrate in nitrided ferrochrome will lead to a more complete reduction of titanium and the formation of titanium nitrides in the alloy, which will increase the absorption of nitrogen and titanium by steel and allow them to modify the molten metal. The introduction of nitrated ferrochrome of less than 10% will worsen the conditions for the formation of tntane nitrides and will increase the thermal character of the mixture. When the content of nitrated ferrochrome more than 20% of the heat released may not be enough to melt the metal part, which can lead to an uneven distribution of chromium in the metal.
Содержание св зи менее 0,5% недостаточно дл получени плотного прессованного брикета. Увеличение св зки более 5% приведет к загр знению металла посторонними примес ми.A bond content of less than 0.5% is not enough to produce a dense pressed briquette. An increase in binding of more than 5% will lead to contamination of the metal with impurities.
