Description
Изобретение относитс к цветной металлургии, в частности к конвер тированию медных никельсодержащих белых штейнов.This invention relates to non-ferrous metallurgy, in particular to the conversion of nickel-containing copper white mattes.
Цель изобретени - сокращение содержани никел в черновой меди и содержани меди в свернутом никелевом шлаке.The purpose of the invention is to reduce the nickel content in blister copper and the copper content in the rolled nickel slag.
Результаты осуществлени предлагаемого способа в сравнении с известными приведены в таблице.The results of the implementation of the proposed method in comparison with the known are given in the table.
Пример. В 80-тонном конвертере после слива шлака холостой продувки ведут второй период процесса (варка черновой меди), температура 1280 С. Загружают 10 т холодных присадок и конвертер ctaв т под дутье. .Продувку ведут 30 мин ро начала выделени металлической фазы. Начало вьзделени металлической фазы определ ют по пробе на ломке из фурмыExample. In the 80-ton converter, after the slag is drained, idle purging is carried out for the second period of the process (boiling of blister copper), temperature 1280 C. 10 tons of cold additives are charged and the converter is charged under the blast. . The stripping is carried out for 30 minutes before the start of the precipitation of the metal phase. The onset of metal phase precipitation is determined by sampling from a tuyere for breaking
конвертера. Температура массы в конвертере в это врем 1240 С.converter. The mass temperature in the converter at this time is 1240 C.
Начина с этого момента, в конвер.Starting from now on, in the envelope.
тер загружают известн к в количестве 2,0% от массы расплава и продувку ведут до получени черновой меди и никелевого шлака. Общее врем продувки 2 ч 10 мин. Содержание СаОTer load limestone in an amount of 2.0% by weight of the melt and purge is carried out to produce blister copper and nickel slag. Total blow time 2 h 10 min. CaO content
в известн ке 56% (пример 2).in limestone, 56% (example 2).
Температура черновой меди 1190 С, содержание никел в черновой меди 0,5%, отношение меди к никелю в никелевом шлаке 1,56. Шпак получаютThe temperature of blister copper is 1190 C, the nickel content in blister copper is 0.5%, the ratio of copper to nickel in nickel slag is 1.56. Shpak receive
сухой свернутый, из-под которого хорошо и полно сливаетс чернова медь.dry rolled up, from under which fine copper merges finely.
Аналогично провод т другие промышленные опыты, измен количествоSimilarly, other industrial experiments are carried out, changing the amount
