The International Metals Reclamation Company, INMETCO, is located 35 miles northwest of Pittsburgh in Ellwood City, PA. Since 1978, INMETCO has recycled common industrial metal wastes such as EAF dust, mill scale, swarf, and flue dust from stainless steel manufacturers. INMETCO became a subsidiary of our company in 2009.
Mill scale is formed on the outer surface of plates, rolls, sheets or profiles when iron and steel are heated for rolling, forging, or other processing. Being produced during the reheating, conditioning and hot rolling operation, mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break ...
Rolling Mill Scale Said Mechachti 1, Omar Benchiheub 1, S alim Serrai 1, Mohamed 2 Abstract ² The objective of this work is the recycling of mill scale formed during the steel hot rolling process with a reducing gas (carbon monoxide) in order to produce iron powder having characteristics required by powder metallurgy.

B. STEEL MILL CONTACT WATER TREATMENT In the steel manufacturing process where the molten steel is cast, high volumes of water are used to quench and cool the steel. This contact or direct cooling water becomes contaminated with high levels of suspended solids and mill scale .
Mill scale, a potential raw material for recycling from hot rolling mill operations is chosen and one step thermochemical reduction technique is employed to beneficiate the iron content in the ...
Mill Scale 400 Recycling Mill Scale Sourcing We offer Mill Scale from major production sources in the US for export or domestic use Please contact us for an analysis and current pricing information Current allotments of materials are available in volumes of 200 tons to several thousand tons per month
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

May 25, 2017· Uses and recycling of mill scale. Mill scale though has a high level content of iron (68 % 72 %) yet it is still considered as an industrial waste in the form of iron oxide mainly because it gets contaminated with water and oil during the process of rolling. Most of the mill scale in a steel plant is recycled in the production of either iron ...
2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic bluegray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
Carriage requirements of Mill scale under the IMSBC Code As this is a cargo that is not listed in the IMSBC Code, shipment of such cargoes can only take place under section of the said Code meaning that approval would have to be sought by the competent authority of the ports of loading and discharge as well as the vessel''s flag State (essentially a tripartite agreement).
Nov 29, 2013· Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.
contained mill scale (type B and C), the big bags of the mixture of mill scale together with coke and lime (as reducing agents) were charged into the furnace through scrap charging bucket. The summary of the big bag coke and lime additions proportional to the mill scale weight in each type of trial heats is listed in table 2. In case of type
Mill Scale Uses and Applications Finishing. Mill Scale Uses and Applications. A discussion started in 2002 but continuing through 2019. 2002. Q. My company uses iron ore (magnetite) in its process. However, a large amount of mill scale has become available and we are looking at it as a substitute or supplement. Waste paper letsrecycle
