Mill scale Wikipedia

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, 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 mills.

Mill Scale Filtration Plant,Mill Scale Filtration

In steel production process of hot rolling and casting large amounts of water are used depending on the scale of the operation. As steel leaves the casting operations, cooling and cutting with water produces mill scale (iron oxides). This hot water from the mills is transported to Scale pit for the first stage of clarification. This partly clarified water is pumped to settling tank (Second stage of clarification) for

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. This can contribute organics, heavy metals, and other contaminants to the scale pit which must be accounted for in any treatment

What exactly is Mill Scale and what is done about it

In a rolling mill where the steel will be stretched and squished the mill scale will first be removed mostly by water jets, or by sand blasting in some shops or by vibrating rolls in others and the mill scale will fall into a pit below the equipment where it will also be joined by rolling mill lubricants and bearing oils and water. From there it will be pumped to a holding pond, where companies like Harsco will be paid by

Production of cleaner mill scale by dynamic separation

01/03/2018· The descaling water and the cooling water wash the mill scale away from the steel surfaces, flow with the mill scale into the flumes underneath the rolling lines, run at a high speed in the flumes and eventually are discharged into the deep and wide mill scale pits. The wastewater in the mill scale pits becomes fairly calm. By gravity, the mill scale settles down to the bottom of the pits. The settled mill

Scale formation and its removal in Hot Rolling process

During hot rolling of steel, its surface is exposed to air which leads to oxidation, resulting in scale formation. The scale formation is affected by the temperature, steel grade, surrounding atmosphere and the exposure time. There are two kinds of scales relevant in rolling mills sticky and dry scales. Sticky scales can be removed most effectively by use of high pressure water jets upto

Method for removing oil from mill scale and recovering

Iron oxide scale is continually formed on the surface of the hot steel. This scale is repeatedly stripped away by the stresses of rolling. The scale falls, together with the emulsified oil, into collection pits beneath the rolling mill, whence the oil emulsion is recycled via sumps and filters. The scale accumulates and is periodically removed. This oil coated oxide scale is generally referred to in the art as "mill scale" or
