4/2/2011· A.E. Morris, M. Wadsley, in Encyclopedia of Materials: Science and Technology, 2001. 4.1 Smelting of Lead. The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting.Environmental and energy considerations have prompted studies of a more direct route, a so-called "direct" smelting process.

blast furnace machine equipments

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the ...

Fine Ore Injection into Blast Furnace through Tuyeres

Injecting fine iron ore or pulverized coal into a blast furnace through tuyeres in large quantities brings about the following advan-tages compared with conventional blast furnace operating methods: 1) The charging of sinter from the furnace top can be decreased, which reduces the load on a sintering machine significantly, lead-

impacts on sinter quality and sintering performance. In the meantime, an increasing number of large blast furnaces with inner volumes of more than 5000 m3 have been built in East Asia which require more sinter and are often more demanding in terms of the quality requirements of the ferrous materials. Finally, sinter plants are facing

IRON ORE SINTERING PART 2. QUALITY INDICES AND …

Efforts are being made to supply blast furnace operators with high quality sinter. Sinter quality control, by means of adequate sintering, is important in order to operate blast furnaces at a low fuel rate and stable operating rate. In Western Europe, 9 countries operate 36 sinter plants which in 2004 manufactured 100.8 million tons of sinter.

Perfect Sinter—The Dream of the Blast Furnace Operator

compromise between the productivity and quality targets, however, the sinter quality is paramount in importance for blast furnace operation. If the production of high-sinter quality leads to a lack of the required sinter quantity, then this situation can be rectified with relatively low investment expenditures, as outlined in the next section.

Blast furnace | metallurgy | Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from ...

percentage of sinter in blast furnace feed

Sinter represents approximately 70% of blast furnace feed in Asia. The properties of the sinter, such as strength, reducibility and other high temperature properties go a long way to determining the overall productivity and efficiency of the iron making process.

Sinter plant - Wikipedia

1.2. Why sintering. Lead and zin metals are produced in blast furnace. In a blast furnace, ore, coke and flux are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions take place throughout the furnace as the material moves downward.

EFFECT OF MAGNETITE, HEMATITE AND PELLET SCREENINGS …

availability of high quality sinter feed [1]. The trend has shown increasing gangue contents, leading to lower iron content and as a consequence, higher slag volumes in the blast furnace. In order to maintain iron content and gangue levels of sinter feed, the sinter ores became finer due to an increased necessity of beneficiation at the mining ...

Copper staves for blast furnaces - kme.com

Burden composition and quality have been observed to significantly affect heat loads and heat fluctuations. Blast furnace burden with more than 70 % sinter can result in peak loads of 100,000 to 200,000 W/m 2. While burden with a high percent - age of pellets or lump can generate peak heat loads of over 400,000 W/m 2. Depending on the

Sintering | Eurotherm by Schneider Electric

Two important properties of sinter are basicity, which is controlled by the amount of limestone, and strength, which is controlled by coke content. The sinter is now suitable for use in the blast furnace. Conveyors transport the material to the blast furnace stock house, where it is added to other materials to form the blast furnace burden.

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
