Mill Scale is what We Know Best

Millscale.org is offering Mill Scale from production sources in the U.S. For export or domestic use. Please contact us for analysis and current pricing information. Current allotments of materials are available. Spot purchases or potential long term contracts. All material we sell is produced in the USA, is screened clean and will meet standard specification boundaries.

These materials used to be considered a waste streams by most steel producers in the U.S. When China entered the Worldwide steel market all available ferrous raw materials were considered potential supply options. These materials are a very good material for use in steel making and also has many other uses that we will highlight. Many factories mix a certain amount of this material with their iron ore fines before they are sintered to help boost the iron content. Another main use is for cement production but for this purpose lower quality materials can be used as well as iron ore and other materials.

Our company deals directly with producers here in the U.S. and has for many years. We move 7000 tons plus a month long term and occasionally we are involved in large export contracts. We can supply higher grade materials for steel making or lower grades for cement use. Please contact us for current availability.

What is Mill Scale?

When we sometimes explain the materials we sell, I reference TV programs that explain steel manufacturing. When the TV program shows a red hot slab or plate of steel coming out of the steel mill’s furnace: Mill scale is basically the rust coating which forms on the poured steel or newly cast surface. The material appears flaky and can be seen easily on the red hot surface. The materials are produced on the plates outer surface, profiles or sheets. Production starts by rolling the steel billets and hot iron in steel rolling mills.

The oxides are like a hard brittle material which is mainly composed of mostly ferric, iron oxides and is generally bluish black in color. Also produced during hot rolling, conditioning and reheating operation for new steel production, initially the material adheres to the surface of the steel and also protects it from atmospheric corrosion. The scale is taken off by air blown or physical shaking, the material is then piled up, put into containers or hauled away to storage areas.

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, mineralogical and physical properties, the substance is also used as a raw material in the sintering process as well.

Although, this material is a waste stream, with the heavy depletion of many standard iron/steel scrap sources in the world many producers are now using scale to add ferrous (iron) units to pre-sintered materials. Composition does depend on the type of steel being produced.

For the most part this byproduct contains a high amount of iron as well as low amount of alumina and silica, called residuals. Hence, recycling it via the sintering process will assist in saving other raw materials like limestone and iron ore. Some of the desired sinter properties can be achieved by using 40 to 50 kg of recycled materials per sinter ton.

We will discuss material uses both general recycling uses and specific industrial applications.

As discussed Iron Oxide or scale refers to the substance that is formed due to oxidation of steel during operations like hot rolling, hot press, hot forming, heating/reheating, continuous casting, flame scarfing, conditioning, etc. Other than precious metals, all other metals are found in nature as oxides. The spontaneous corrosion of the surface of steel into ferrous oxide results in creation of scale. We will list material uses in industry today and the future.

While discarded earlier as an unavoidable waste product generated during the steel manufacturing process, it is now possible to remove the scale by a combination of process waters and gravity separation, this generates a useful material.

Batteries

This byproduct can be mixed with copper during hot rolling and forging processes to manufacture the negative electrode or plates in alkaline batteries.

Catalysts

Mill scale can be utilized as catalysts in chemical processes requiring iron oxides to produce acetic acid.

Cement clinker

One of the most prominent mill scale uses is Cement. Adding mill scale to the combustion area when manufacturing cement clinker converts unwanted and potentially-dangerous hydrocarbon gases into less volatile gas products. Further, it can be used as a raw material for manufacture of cement clinker by mixing it with feedstock materials before introduction of the raw material into the heated rotary kiln.

Counterweights

Composite counterweights, which are commonly used in industrial manufacturing processes and machines, consist of a waste-product or by-product of an industrial process that is bound with material of uniform mass. These ferrous byproducts can be used in the manufacture of counterweights. The product so prepared is then used in the finished machine or equipment.

Mill scale is being used in place of concrete as counterweights in washing machines. The material is mixed with water and used as filling material. These counterweights are used in the manufacturing process of basic metals as well as for production of general machinery and transportation equipment.

Counter-Weights

Heat Conservation

Use of mill scale for separation of volatile metals, iron, slag, and other impurities facilitates heat conservation and improves energy efficiency. Processing waste materials in an Electric Arc Furnace can help improve productivity and output and reduce wastage. Heat conservation helps avoid unnecessary wastage of resources when processing waste materials.

Generation of Exothermic Power

Combining waste products generated during the manufacturing process of heavy metals with mill scale will result in a low-density material that can injected into the furnace to create an exothermic reaction without excessive use of raw materials.

Iron Feedstock

This material is a waste product that is rich in iron making one of mill scale uses a FE additive. This material can be mixed with industrial waste and by products to create iron feedstock for the manufacturing process. Mill scale can be processed through leaching, roasting, and other processes.

Ferro-Alloys

Refining ferro-alloys involves addition of oxidizing agents that will combine with the impurities and rise to the surface. Or, the slag will separate or get diffused as gas by products. Mill scale is a suitable agent for oxidation to remove impurities from alloys.

Mixed Fertilizers

Magnetic carrier additives can enhance the performance and efficacy of mixed fertilizers. Mill scale is used as the magnetizing synergist agent to provide additional nutrients to the crop. Mill scale is also used as a de-siliconization agent that is an integral part of the phosphate fertilizer production process.

Mill scale can also be used in the manufacture of water-treatment chemicals that are used in agricultural, forestry, fishing, and scientific activities related to research and development.

Foundry Iron

Mill scale is used as a source of iron for manufacture of iron and steel from scrap materials. The submerged arc furnace produces very little slag, which facilitates use of mill scale as reducing agents to produce alloy metal with very little slag and impurities.

More Mill Scale Uses

Friction Products Like Brakes.

Auto brakes rely on friction to bring the vehicle to a halt. In products that use sponge iron as the principal material for generating friction, mill scale can be used to replace up to half of the sponge iron without compromising on efficacy or performance of the friction material. This makes mill scale a useful raw material for the manufacture of a wide range of equipment including industrial machines as well as consumer goods.

Colored Glass

Colored glass is made primarily by using slag contents that contain iron, manganese, and other metals that causes the glass to have the desired hue. Small amounts of mill scale can be used as a replacement for iron-based colorants during the glass manufacturing process.

Heavy Concrete

This type of concrete does not require additional thickeners and is manufactured by mixing cement, a heavy aggregate and water. Mill scale can be combined with feedstock and used as a part of the heavy aggregate material that differentiates this type of concrete from standard concrete.

Iron Oxides

Heating mill scale and iron oxide will result in production of iron oxide pigments of shades of red, brown, or black. Further addition of mill scale and heating the resulting mixture will result produce iron oxide black pigment.

Iron Salts

Leaching of mill scale at high temperatures in a high-pressure environment can lead to recovery of ferric oxide, which can then be used for various industrial applications and processes.

Melting Charge

Mill scale can be kept in containers that are then used as electric furnace melting charge controllers.

Mineral wool

Mineral wool requires use of fluxing materials during its production process. Mill scale can be used as one such material.

mineral-wool

Iron Oxide Paint

Paint manufacturing requires use of iron oxide paint pigments. Mill scale can be used in the cores to help achieve the right balance and proportion of iron, which is the most significant component of the pigment.

Radiation Shielding

Shielding material consists of building material combined with a shielding component that makes it possible for the material to reflect or absorb electromagnetic radiation. Since ferrous materials can be used for shielding, dry mill scale can be used to manufacture materials that are capable of blocking electromagnetic radiation.

Refractories

Refractory material is made by crushing dolomite and mixing it with a flux suspension liquid or paint. Mill scale can be used as flux material that is combined with the liquid binder and ultimate used to produce the refractory material.

Road Construction

For building roads that offer greater adhesion between the tire and the surface, greater ability to withstand abrasive contact, and even conduction of surface heat, mill scale can be added to the building material as an additional component to enhance safety, quality, and durability of the surface of the road.

Sinter Material

Mill scale is a byproduct that can be used for sintering iron and zinc ore. The scale is mixed with a fuel and an agglomeration agent is used to create the mixture. The sinter bed is then heated to bring the process to its conclusion.

Slag Formers

For foaming slag to be truly effective, the foam must be created up to a certain height on top of the molten steel material. Introducing mill scale will ensure the foam is of the amount and volume that will ensure the molten steel is completely protected by the foaming slag.

Stone Production

Mill scale is an ideal raw material for manufacturing high-content stone with magnetite ore for use in high-grade food, medical, and military equipment. This stone has very little impurities and undergoes a stringent purification process.

Tool Steel

Removing carbon in specific parts of tool steel molds where free carbon may impair safety or strength can be done by introducing an oxidizing agent like scale. This material offers greater control over the overall content of free carbon along with the ability to vary carbon content in different parts of the metal product or article which is a very specific example of mill scale uses.

Tool-Steel

Water and Soil Treatment

Contaminated soil or ground water containing halogen compounds can be purified by use of iron-based purification particles. Mill scale is an effective purification material that can be introduced into the contamination-removal process.

Welding Electrodes

Electric arc welding electrodes are made of an alkali meal oxide that is combined with metal compounds like oxides of iron, manganese, aluminum or silicon dioxide. Mill scale is an effective source of iron oxides for the manufacture of electrodes that are used in the welding process.

Heavy Weight Aggregates

Heavy concrete and mortar require fine aggregate particles with metal iron as its primary constituent one of the major mill scale uses. The heavy weight aggregate is manufactured by mixing materials like mill scale of specific diameters, pig iron particles, and granulated slags.

Mill scale uses are multiple, this byproduct is versatile and can be used for coloring, binding, heat transfer, lubrication, viscosity adjustment, and as agents for binding or absorbing gases or liquids.
