E-mail address: [email protected] Received 12.04.2017; accepted in revised form 23.06.2017 Abstract The aim of the current study was to examine the structure of an alloy treated at various temperatures up to 2,000–2,100 °C. Among research techniques for studying alloy structure there were the electron and optical microstructure, X-ray structure, and spectral analysis, and for studying the developed furnace geometric parameters the authors employed mathematical modeling method. The research was performed using aluminum smelting gas-fired furnaces and electric arc furnaces. The objects of the study were aluminum alloys of the brand AK7p and AK6, as well as hydrogen and aluminum oxide in the melt. For determining the hydrogen content in the aluminum alloy, the vacuum extraction method was selected. Authors have established that treatment of molten aluminum alloy in contact with carbon melt at high temperatures of 2,000–2,100 °C has resulted in facilitating reduction of hydrogen and aluminum oxide content in the melt by 40- 43% and 50-58%, respectively, which is important because hydrogen and aluminum oxide adversely affect the structure and properties of the alloy.

  • 12.8 Secondary Aluminum Operations 12.8.1 General Secondary
    12.8 Secondary Aluminum Operations 12.8.1 General1 Secondary aluminum producers recycle aluminum from aluminum-containing scrap, while primary aluminum producers convert bauxite ore into aluminum. The secondary aluminum industry was responsible for 27.5 percent of domestic aluminum produced in 1989. There are approximately 116 plants with a recovery capacity of approximately 2.4 million megagrams (2.6 million tons) of aluminum per year. Actual total secondary aluminum production was relatively constant during the 1980s. However, increased demand for aluminum by the automobile industry has doubled in the last 10 years to an average of 78.5 kilograms (173 pounds) per car. Recycling of used aluminum beverage cans (UBC) increased more than 26 percent from 1986 to 1989. In 1989, 1.3 million megagrams (1.4 million tons) of UBCs were recycled, representing over 60 percent of cans shipped. Recycling a ton of aluminum requires only 5 percent of the energy required to refine a ton of primary aluminum from bauxite ore, making the secondary aluminum economically viable. 12.8.2 Process Description Secondary aluminum production involves 2 general categories of operations, scrap pretreatment and smelting/refining. Pretreatment operations include sorting, processing, and cleaning scrap. Smelting/refining operations include cleaning, melting, refining, alloying, and pouring of aluminum recovered from scrap. The processes used to convert scrap aluminum to products such as lightweight aluminum alloys for industrial castings are presented in Figure 12.8-1A and Figure 12.8-1B. Some or all the steps in these figures may be involved at any one facility. Some steps may be combined or reordered, depending on scrap quality, source of scrap, auxiliary equipment available, furnace design, and product specifications.

  • Colebrook's Involvement with the Iron Industry 1770-1810
    Colebrook’s Involvement With the Iron Industry 1770-1810 Iron has been extracted from ore since prehistoric times. The earliest, of course, would have been metal residue found in the ashes of a fire that had burned in an enclosure consisting of rocks containing iron oxide. The carbon in the burning wood combined with the iron oxide and formed a metal that looked entirely different from the ore. Unbeknownst to the fire tender, two processes were taking place in his primitive campfire. The burning charcoal, which extracted the iron would inevitably carbonize some lumps of it, sometimes turning it into brittle and relatively useless cast iron, and some only far enough to convert it to steel, strong and very useful in its unhardened state. It is therefore almost certain that much of the earliest iron was in fact steel. There must have been a very long time between the discovery that this cold material from the campfire could be beaten into shapes after it had cooled; until the time it was discovered that it was much easier to beat it into shape while hot. The next step would seem to be the discovery that if this freshly beaten shape were suddenly cooled, it became hard and brittle. That knowledge would be taken to the next level by the discovery that gently re-heating this hard, brittle object would leave it hard, but remove the brittleness. Up until the 14th century in Europe, when a deposit of iron was discovered, the local smith converted it with the charcoal of the surrounding forest into wrought iron.

  • The Paper of the Reverberatory Furnace by Dr. Kanno
    World Cultural Heritage—Solving 10 Mysteries of Nirayama Reverberatory Furnace T. Kanno Kimura Chuzosho Co., Ltd., 1157 Shimizu-cho, Shizuoka Prefecture, Japan Key-Words: Nirayama reverberatory furnace, World Heritage, Cannon, Cast iron, Pig iron, Melting temperature, Bellows, Fuel, Firebrick 1. Introduction Nirayama reverberatory furnace is located in Izunokuni city, the Izu Peninsula, Shizuoka Prefecture. As shown in Fig. 1, they are composed of four furnaces in total: two pairs of twin towers, 15.6 m in height.1) Though the existing reverberatory furnace is also in Yamaguchi Prefecture, Nirayama’s is the only existing one which was actually used to melt cast iron in the world. Being one of the constituent properties of “Sites of Japan’s Meiji Industrial Revolution: Kyushu-Yamaguchi and related Areas,” it was decided to be the government’s recommendee for the World Heritage registration in 2015, on September 17th, 2013. Every year one site is selected in the aim of promoting domestic cultural properties for inclusion on the World Heritage List. This application aims to register as one of the group of “Heritages of Industrial Modernization in Kyushu area and Yamaguchi,” not Nirayama’s individually. The group is Fig. 1 Nirayama reverberatory furnace and 24 composed of 8 areas, 11 sites, and 23 properties, including pounder the castle town in Hagi city, Shuseikan in Kagoshima city, Nirayama reverberatory furnace in Izunokuni city, Hashino blast furnace in Kamaishi city, Mie Tsu Naval Training Center in Saga city, Hashima Coal Mine and Glover House in Nagasaki city, Miike Coal Mine in Arao city and Omuta city and Yahata Steel Works in Kitakyushu city.

  • Lecture 11 Melting Practices Melting Is an Equally Important Parameter For
    Lecture 11 Melting Practices Melting is an equally important parameter for obtaining a quality castings. A number of furnaces can be used for melting the metal, to be used, to make a metal casting. The choice of furnace depends on the type of metal to be melted. Some of the furnaces used in metal casting are as following:. Crucible furnaces Cupola Induction furnace Reverberatory furnace . Crucible Furnace. Crucible furnaces are small capacity typically used for small melting applications. Crucible furnace is suitable for the batch type foundries where the metal requirement is intermittent. The metal is placed in a crucible which is made of clay and graphite. The energy is applied indirectly to the metal by heating the crucible by coke, oil or gas. The heating of crucible is done by coke, oil or gas. Coke-Fired Furnace(Figure 13) . Primarily used for non-ferrous metals Furnace is of a cylindrical shape Also known as pit furnace Preparation involves: first to make a deep bed of coke in the furnace Burn the coke till it attains the state of maximum combustion Insert the crucible in the coke bed Remove the crucible when the melt reaches to desired temperature Figure 13: Coke Fired Crucible Furnace . Oil-Fired Furnace. Primarily used for non-ferrous metals Furnace is of a cylindrical shape Advantages include: no wastage of fuel Less contamination of the metal Absorption of water vapor is least as the metal melts inside the closed metallic furnace Cupola Cupola Cupola furnaces are tall, cylindrical furnaces used to melt iron and ferrous alloys in foundry operations.
