Slag. Slag is produced during the ironmanufacturing process. During the manufacturing process the materials are heated in a blast furnace to a molten state. The slag rises to the top and is separated from the iron for further processing. When slag is separated from iron and rapidly cooled with water (granulated), the morphology of the slag changes.
Fluxes with a lime content produce an adherent slag which is difficult to remove. The ease of slag removal for the principal flux types are: Rutile or acid fluxes large amounts of titanium oxide (rutile) with some silicates. The oxygen level of the weld pool is high enough to give flat or slightly convex weld bead.
Slag is said to be refuse produced as a result of melting non ferrous material which have a high melting point. These products are usually made up of liquid non metallic components and are an outcome of alloying and oxidation in air. Whereas dross is said to be related to non ferrous alloys,...
sixinline electric arc furnaces. The slag is milled and then classified into two product sizes suitable as a raw material for both the sulphate and chloride pigment processes. The high quality iron produced during the reduction process is further processed to produce various grades of lowmanganese iron.
Refining process in oxygen converter produces converter slag as a by – product, that has relatively stabile properties and composition. Different situation is related to slag produced in process of electric arc furnace steelmaking. Its character and composition are in close relation to the processes used for steel melt preparation in the
of more ores and less quartzite, the smelting process produces more slag and requires more electric energy to heat and melt the slag. Keywords—Ferrochrome production, ferroalloy process optimization, chrome ore I. INTRODUCTION IGH carbon ferrochrome (HCFeCr) is produced by carbothermic reduction of chrome ore. Electric power is
Vanadium bearing coproduct slag is generated during steel production from iron sands in New Zealand in a process similar to the South African process. The iron from these operations contains about % vanadium which is removed as slag by low temperature treatment with oxygen.
The slag goes to a disposal area and the molten iron is directed into molds known as pigs where it solidifies to pig iron and is transferred to the next stage of processing. Converting Pig Iron to Wrought Iron and Steel. The pig iron can be further refined to produce steel or wrought iron.
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
A slag rock is an artificial rock. Slag is made as a byproduct of industrial processes such as metal mining. It is also produced by iron smelting such as in steel mills.
Jan 03, 2014· How is LD slag produced? Liquid LD slag is produced during the LD process as pig iron is processed into crude steel. Slag is not a random product, but rather a consequence of the LinzDonawitz process, which uses steel as well as LD slag. The slag is separated from the crude steel, separately processed, and its chemical composition analyzed.

Jan 15, 2014· At the voestalpine Group, it is primarily LD slag which is produced and then processed in a resourceefficient manner. At the voestalpine Group, the conservation of resources has long been an important part of the production process as a whole.
The titanium slag produced from this process represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process. In the case of the chloride process, the titaniumrich slag is further acidleached by a hydrometallurgical process.
Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
