Description
Изобретение относится к цветной металлургии и, в частности, к способам получения оловянистой бронзы.The invention relates to non-ferrous metallurgy and, in particular, to methods for producing tin bronze.
Известен способ получения оловянистой бронзы, при котором плавку оловянистой бронзы ведут в тигельных, плазменных и электрических печах. При приготовлении оловянистой бронзы из чистых металлов плавку начинают с расплавления меди. Затем медь раскисляют фосфором и последовательно вводят в ванну цинк, свинец, олово (В.М.Чурсин. Технология цветного литья. - М.: Металлургия, 1967, с.252).A known method of producing tin bronze, in which the melting of tin bronze is carried out in crucible, plasma and electric furnaces. In the preparation of tin bronze from pure metals, melting begins with the melting of copper. Then the copper is deoxidized with phosphorus and zinc, lead, and tin are successively introduced into the bath (V.M. Chursin. Color casting technology. - M.: Metallurgy, 1967, p. 252).
Однако данный способ имеет недостаток, связанный с необходимостью применения чистых шихтовых материалов (медь, олово), что повышает стоимость бронзы.However, this method has a disadvantage associated with the need to use pure charge materials (copper, tin), which increases the cost of bronze.
В качестве прототипа принят способ получения оловянистой бронзы, включающий восстановительную плавку оловосодержащих шлаков с вторичными медьсодержащими материалами (SU 1782993 А1, стр.1-2, МПК С 22 В 7/04, опубл. 23.12.1992). Недостатками данного способа являются длительность операций приготовления оловянистой бронзы и необходимость применения чистых материалов.As a prototype, a method for producing tin bronze was adopted, which includes reducing smelting of tin-containing slags with secondary copper-containing materials (SU 1782993 A1, pp. 1-2, IPC C 22 V 7/04, publ. 23.12.1992). The disadvantages of this method are the duration of the operations of the preparation of tin bronze and the need for pure materials.
Технической задачей, на решение которой направлено данное изобретение, является сокращение времени и трудозатрат на получение оловянистой бронзы.The technical problem to which this invention is directed is to reduce the time and labor required to obtain tin bronze.
Указанная задача решается тем, что оловянистую бронзу получают плавкой из медного минерального концентрата, содержащего в %: Cu2S - 20-25; CuFeS, FeS - 20-25; AsFeS - 1,5-2,5; SnO2 - 3-5; Zn - 1,5-2,0; Pb - 1,5-2,0; ZnS - 1,5-2,0; SiO2 - остальное, который перед плавкой обжигают при температуре 800-850°С и изготавливают из него глины, извести и цемиша окатыши, сушат их и подвергают плавке под слоем молотого графита в электродуговой печи. При этом не применяют ни медь, ни олово в качестве чистых шихтовых материалов, что позволяет сократить время получения оловянистой бронзы и снизить трудозатраты. Химический состав получаемой однофазной бронзы: 91,76% Cu; 4,21% Sn; 0,31% Si; 0,42% Zn; 1,8% Pb; 3,06% Fe.This problem is solved in that the tin bronze is obtained by melting of copper mineral concentrate containing in%: Cu 2 S - 20-25; CuFeS, FeS - 20-25; AsFeS - 1.5-2.5; SnO 2 - 3-5; Zn - 1.5-2.0; Pb - 1.5-2.0; ZnS - 1.5-2.0; SiO 2 - the rest, which is fired before melting at a temperature of 800-850 ° C and made from it clay, lime and cement pellets, dried and melted under a layer of ground graphite in an electric arc furnace. At the same time, neither copper nor tin is used as pure charge materials, which reduces the time for obtaining tin bronze and reduces labor costs. The chemical composition of the obtained single-phase bronze: 91.76% Cu; 4.21% Sn; 0.31% Si; 0.42% Zn; 1.8% Pb; 3.06% Fe.
Пример реализации способаAn example implementation of the method
Концентрат меди, содержащий в %: Cu2S - 20-25; CuFeS, FeS - 20-25; AsFeS - 1,5-2,5; SnO2 - 3-5; Zn - 1,5-2,0; Pb - 1,5-2,0; ZnS - 1,5-2,0; SiO2 - остальное, подвергают обжигу (800-850°С). При этом происходит удаление мышьяка, частичное удаление серы (SO2) и перевод части железа из сульфидной формы в оксидную, что позволяет получать богатый по меди штейн и отделить часть железа от меди, переведя его частично в жидкий шлак. Для проведения обжига емкость с концентратом помещают в печь сопротивления и нагревают до 800-850°С. После нагрева в емкость вводят трубку, через которую подают сжатый воздух, для восстановления меди из сульфидов. Из обожженного концентрата (14,700 кг), воды, глины (4,400 кг), извести (0,735 кг), цемиша (0,147 кг) изготавливают окатыши диаметром 20-40 мм. Сушат окатыши в прокалочной печи при температуре 250°С в течение 3 ч. Обожженный концентрат в виде окатышей расплавляют под слоем молотого графита (30 мас.% от веса шихты) в электродуговой печи. Плавку ведут "на блок" в 20 кг при рабочем напряжении 60 В и токе 1000 А с нижним запалом на коротких дугах, после расплавления - в режиме длинных дуг. Расплавление происходило в течение 5 минут при 1700°С, выдержка расплава - 7 минут.Copper concentrate containing in%: Cu 2 S - 20-25; CuFeS, FeS - 20-25; AsFeS - 1.5-2.5; SnO 2 - 3-5; Zn - 1.5-2.0; Pb - 1.5-2.0; ZnS - 1.5-2.0; SiO 2 - the rest is subjected to firing (800-850 ° C). In this case, arsenic is removed, sulfur (SO 2 ) is partially removed, and part of the iron is converted from the sulfide form to the oxide form, which makes it possible to obtain matte rich in copper and to separate part of the iron from copper, partially converting it into liquid slag. For firing, the container with the concentrate is placed in a resistance furnace and heated to 800-850 ° C. After heating, a tube is introduced into the container through which compressed air is supplied to restore copper from sulfides. Pellets with a diameter of 20-40 mm are made from calcined concentrate (14,700 kg), water, clay (4,400 kg), lime (0.735 kg), and cement (0.147 kg). The pellets are dried in a calcining furnace at a temperature of 250 ° C for 3 hours. The calcined concentrate in the form of pellets is melted under a layer of ground graphite (30 wt.% Of the charge weight) in an electric arc furnace. Melting is carried out "on a block" of 20 kg at an operating voltage of 60 V and a current of 1000 A with a lower fuse in short arcs, after melting - in the mode of long arcs. Melting took place for 5 minutes at 1700 ° C, exposure of the melt - 7 minutes.
Таким образом, способ позволяет, не применяя чистые шихтовые материалы (медь и олово), сократить время получения оловянистой бронзы и снизить трудозатраты.Thus, the method allows, without using pure charge materials (copper and tin), to reduce the time to obtain tin bronze and reduce labor costs.
