Description
Известно производство хр01мистых и хромоникелевых сталей, содержащих хрома более 2-SVo, в дуговых электропечах, что св зано с удорожанием стоимости этих сталей. Производство же высоколегированных хромистых и хромоникелевых сталей в основных мартеновских печах затруднительно .Production of chrome-nickel and nickel-chromium steels, containing more than 2-SVo chromium, in electric arc furnaces is known, which is associated with a rise in the cost of these steels. The production of high-alloyed chromium and nickel-chromium steels in the main open-hearth furnaces is difficult.
Предложенный способ получени высоколегированных хромистых и хромоникелевых сталей осуществл етс путем продувки кислородом в основном конверторе высоколегированных хромистых и хромоникелевых чугунов, выплавленных в доменных печах. Так же продувкой кислородом в основном конверторе высокоуглеродистого феррохрома получаютс малоуглеродистые марки феррохрома. Использование предложенного способа получени высоколегированных хромистых и хромоникелевых сталей и малоуглеродистого феррохрома позвол ет быстрее организовать их производство при меньщих затратах на сырые материалы , электроэнергию и оборудование, а также освободит значительное количество электропечей дл производства более ответственных марок сталей.The proposed method for producing high-alloyed chromium and nickel-chromium steels is carried out by blowing oxygen into the main converter of high-alloyed chromium and nickel-chromium cast irons smelted in blast furnaces. Also, low-carbon grades of ferrochrome are produced by purging with oxygen in the main converter of high carbon ferrochrome. Using the proposed method for producing high-alloyed chromium and nickel-chromium steels and low-carbon ferrochrome makes it possible to organize their production faster with lower costs for raw materials, electricity and equipment, and also releases a significant amount of electric furnaces for the production of more responsible steel grades.
В доменных печах легко осуществить производство хромистого и хромоникелевого чугуна с содержанием хрома в пределах от 3 до 25Vo и никел от 1 до 10%.In blast furnaces it is easy to carry out the production of chromium and nickel-chrome iron with a chromium content ranging from 3 to 25Vo and nickel from 1 to 10%.
При использовании хрома в пределах 70-80Vo в процессе продувки этого чугуна возможно получить весь сортамент хромистых и хромоникелевых сталей вплоть до нержавеющей и даже более высоколегированных , выплавл емых в насто щее врем в электропечах. Процентное содержание никел в готовой стали значительно повышаетс по сравнению с содержанием его в хромоникелевом чугуне, так как никель в процессе продувки не выгорает, а такие элементы как С, Сг, Fe, Мп и Si выгорают в незначительных пределах. Подача кислорода в конвертор производитс через водоохлаждаемую фурму системы Г. П. Иванцова.When using chromium in the range of 70-80Vo in the process of blowing this iron, it is possible to obtain the entire range of chromium and nickel-chromium steels up to stainless and even more high-alloyed, currently produced in electric furnaces. The percentage of nickel in the finished steel is significantly increased compared to its content in nickel-chromium iron, since nickel does not burn out during the purging process, but elements such as C, Cr, Fe, Mn, and Si burn out to an insignificant extent. Oxygen is supplied to the converter through a G. P. Ivantsov water-cooled tuyere system.

Выплавку хромистого и хромоникелевого чугуна в доменных печах можно вести на железной и хромистой руде, а также на руде типа Акермановского рудника халиловского месторождени и др. С целью повышени содержани железа, хрома и, в особенности, никел в доменной шихте , целесообразно вводить в нее высоколегированную хромоникелевую стружку.Smelting of chromium and chromium-nickel iron in blast furnaces can be carried out on iron and chromium ore, as well as on ore such as the Ackerman mine of the Khalilov deposit, etc. nickel chips.
Дл получени малоуглеродистого феррохрома из высокоуглеродистого доменного феррохрома также производитс продувка кислородом.Oxygen scavenging is also carried out to produce low carbon ferrochrome from high carbon domain ferrochrome.
