Description
Изобретение относитс к металлургни , а именно к выплавке меди и ее сплавов, и может быть использовано в черной металлургии дл отливки медных наконечников воздушных и жис- лородных фурм доменных и мартеновских печей и конвертеров, в цветной металлургии дл переплава медного лома и стружки и выплавки медных сплавов, в машино- и судостроении дл производства бронзовых отливок при изготовлении и ремонте узлов и деталей трени .The invention relates to metallurgy, namely to the smelting of copper and its alloys, and can be used in ferrous metallurgy for casting copper tips of air and natural tuyeres of blast-furnace and open-hearth furnaces and converters, in ferrous metallurgy for melting copper scrap and chips and melting copper. alloys in engineering and shipbuilding for the production of bronze castings in the manufacture and repair of components and parts of friction.
Целью изобретени вл етс снижение содержани водорода и кислорода в металле, интенсификаци и удешевление процесса.The aim of the invention is to reduce the content of hydrogen and oxygen in the metal, to intensify and reduce the cost of the process.
.Примеры. Опыты проводили в открытой индукционной печи. Вместо набивного тигл из огнеупорной массы, используемого в таких печах, примен ли графитовый емкостью 700 кг металлического расплава.. Источник питани печи бьш переделан на частоту 50 Гц, так как известно, что наиболее интенсивное перемешивание расплава обеспечиваетс при плавлении на токе промьшшенной частоты..Examples. Experiments were performed in an open induction furnace. Instead of a printed crucible of refractory mass used in such furnaces, graphite with a capacity of 700 kg of metal melt was used. The furnace power supply was altered at a frequency of 50 Hz, since it is known that the most intensive mixing of the melt is provided by melting at the current of the industrial frequency.
Выплавл ли медь (плавки 1-7) и бронзу БрАЖ9-4 (плавка 8).Б качестве шихтовых материалов использовалиCopper was melted (smelting 1-7) and BrAZh9-4 bronze (smelting 8). The quality of the charge materials used

катодную медь, медную стружку, получаемую при механической обработке заготовок фурм. Дл выплавки бронзы , кроме того, использовали чушко- 5 вый алюминий и прутковую сталь.cathode copper, copper chips, obtained by machining of tuyere blanks. In addition, bronze aluminum and bar steel were used to smelt bronze.
Шихту расплавл ли в тигле и расплав нагревали до 1150-1200 С. Масса расплава 600 кг. В расплав добавл ли закись меди, выдерживали его и 10 наводили шлаковую ванну из буры. Предварительно буру расплавл ли в графитовом тигле в индукционной печи .The mixture was melted in a crucible and the melt was heated to 1150-1200 ° C. The melt mass was 600 kg. Copper oxide was added to the melt, kept there, and 10 were injected with a borax slag bath. Pre-borax was melted in a graphite crucible in an induction furnace.
Затем расплав раскисл ли путем ts Еьщержки его под слоем шлака (раскисление углеродом тигл ) или дополнительно введением фосфористой меди МФЗ, содержащей 10 мас.% фосфора из расчета на 20-30% меньше требуемого количества этого элемента дл нейтрализации 0,03% кислорода .Then the melt was deactivated by ts holding it under a layer of slag (crucible deoxidation) or additionally by introducing phosphorus copper MFZ containing 10 wt.% Phosphorus based on 20-30% less than the required amount of this element to neutralize 0.03% oxygen.
При выплавке бронзы остальные составл кщие металлической шихты вводили в расплав после его раскислени через слой шлака.In the smelting of bronze, the remaining components of the metal charge were introduced into the melt after its deoxidation through a layer of slag.
Количество вводимой закиси меди и врем обработки расплава, способ и врем раскислени и результаты анализа проб металла, отобранных изThe amount of added copper oxide and the processing time of the melt, the method and time deoxidation and the results of the analysis of metal samples taken from

Как видно из таблицы, металл, вьтлавленный по предлагаемому спосо бу, содержит весьма малые количества водорода и кислорода. При этом медь по сумме содержани остальных примесей соответствует бескислородной меди,As can be seen from the table, the metal melted according to the proposed method contains very small amounts of hydrogen and oxygen. At the same time, copper, by the sum of the content of the remaining impurities, corresponds to oxygen-free copper,
Медь, выплавленна в печи ИАТ-0,4С2 была использована дл отливки наконечников фурм доменного и сталеплавильного производства сложной формы с толщиной стенки 8-50 мм и массой 5-125 кг.Copper melted in an IAT-0.4C2 furnace was used for casting lances of blast-furnace and steelmaking of complex shape with a wall thickness of 8-50 mm and a mass of 5-125 kg.
От партии наконечников, отлитых из каждой плавки, отбирали одну отливку, разрезали и исследовалиFrom a batch of tips cast from each heat, one cast was taken, cut and examined.

На пористость. В отливках, получен ных из меди плавок 2-5, поры не обнаружены. В наконечниках, отлитых из остальных плавок, наблюдалась 5 пористость: плавка 1 - значительна , плавка 6 - средн , плавка 7 - отдельные поры.For porosity. In the castings obtained from copper heats 2–5, no pores were found. In the tips cast from the remaining heats, 5 porosity was observed: melting 1 - significant, melting 6 - medium, melting 7 - individual pores.
Пробы плавок 1, 6 и 7 также оказались пористыми, хот и в меньшей 10 степени, чем отливки. Однако. cdoT- ношение пористости в этих пробах такое же, как .и в отливках.Samples of heats 1, 6 and 7 also turned out to be porous, although to a lesser extent than the castings. But. cdoT- wearing porosity in these samples is the same as .and in castings.
Из бронзы БрАЖ9-4 (плавка 8) были отлиты подшипниковые втулки, t5 в которых также не были обнаружены поры.BraZh9-4 bronze (smelting 8) were used to cast bearing bushings, in which t5 pores were also not found.
