Description
Изобретение относитс к способу снижени содержани серы в углеродистом феррохроме при выплавке его в мощных электропечах при работе с закрытым колошником.The invention relates to a method for reducing the sulfur content in carbon ferrochrome when it is smelted in high-power electric furnaces when operating with a closed top chamber.
Известные способы выплавки углеродистого феррохрома требуют кокса с минимальным содержанием серы, снижают содержание окиси хрома в шихте и повышают содержание кремни и углерода в сплаве, что лимитирует увеличение производительности печей.The known methods of smelting carbon ferrochrome require coke with a minimum sulfur content, reduce the content of chromium oxide in the charge and increase the content of silicon and carbon in the alloy, which limits the increase in furnace productivity.
Дл устранени этих недостатков по описываемому способу дл сни}кени содержани серы в углеродистом феррохроме при выплавке его в мощных электропечах при работе с закрытым колощником в шихту ввод т от 3 до 6% (веса плавки) марганцевой руды. В результате введени марганцевой руды в щихту содержание серы в углеродистом феррохроме снижаетс на 25-35% и не превышает пределов, предусмотренных ГОСТом даже при выплавке феррохрома марки хр. 4.To eliminate these drawbacks, using the described method, in order to reduce the sulfur content in carbon ferrochrome when smelting it in powerful electric furnaces, when working with a closed collet box, from 3 to 6% (smelting weight) of manganese ore is introduced into the charge. As a result of the introduction of manganese ore into the binder, the sulfur content in carbon ferrochrome is reduced by 25-35% and does not exceed the limits stipulated by GOST, even when smelting xr grade ferrochrome. four.
Р1спользование предложенного способа в производстве углеродисто го феррохрома позволит снизить содержание серы в феррохроме и повысит производительность печей.Using the proposed method in the production of carbon ferrochrome will reduce the sulfur content in ferrochrome and increase the productivity of furnaces.
