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 As Used In Industrial Recycling. Historically, these materials collected and sold to the cement plants for iron requirements. Also additives for agglomerates but now we are seeing many more industrial applications. This byproduct is a very valuable metallurgical raw material as it contains about 65 to 70% iron. Due to its chemical ...
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 ...

Mill scale is composed of iron oxides mostly ferric and is bluish black in color. ... coating breaks due to handling of the steel product or due to any other mechanical cause. ... in rolling mills will be collected and sent to a sinter plant for recycling.
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
The scale pit is used to remove the larger scale and particulate, as well as to skim the oil from the water and is normally sized for 30–45 minutes of retention time. In some mills, this pit also receives wastewater from the hot roll and other miscellaneous processes throughout the mill.
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.
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 ...
Jul 01, 2014· In the third phase, as the main objective was to identify the mechanism to optimize the removal of zinc mill scale was not used. To mix formulation was taken as the experiment base 7 of the second phase (35% of the EAF dust, 49% of mill scale, 9% ceramic fluorite and coke 7%), which was obtained PCA with % ZnO.
In the whole world, million tons of mill scales are generated annually [3]. Mill scale is suitable for direct recycling to the blast furnace via sintering plant [4]. Ap proximately, 90% of mill scale . Recycling of steel plant mill scale via iron ore sintering. The mill scale contains high amounts of Fe and low amounts of silica and alumina.
Your global resource for nickel recycling and processing, Globe Metal buys all forms of nickel material, including turnings, solid scrap, powder, grinding sludge, filter cake from plating operations, fines, high and lowgrade nickel, nickel waste byproducts, spent catalysts, slag, stainless steel powder, stainless steel mill scale from foundries, alloys, rounds, cutoffs, chips, waste water ...
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
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 .

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 ...
This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process. Experiments were conducted using the mill scale in sinter making from 0 to 70 kg/t of sinter. The total Fe and FeO contents of the sinter increased with the increase in mill scale .
Mill Scale Products are available subject to availability and Spec Requirements.... Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, iron oxides consisting of iron (II,III) oxide, hematite, and magnetite. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling ...
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 .
