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.

mill line are sent to the scale pit to allow the big/ heavy scale separation. The scraper conveyor packages and the pumping pit are located under/next to the rolling mill, consequently the concrete works are not so depth (-5 / -7 m). The scale pit unit collecting all water from contact circuits is located outside the building, because
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 ...

Hot Rolling Mill Process Diagram. Need of temperature measurement or control in Hot Rolling Mill. The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and H ...
Elongated, shallow streaks that have a dull appearance. Silicon streaks are a version of rolled in scale; high silicon grades produce a silicon rich scale (fayalite) when the slabs are in the reheat furnace. This tenacious scale gets rolled in at the hot strip mill, and leaves the elongated pattern when it's removed during pickling.

In certain cases, scale breakers are also integrated, which remove the scale from the steel by deforming it with the aid of rollers. Manual methods to remove scale from steel. Rolling mills offer the advantage that the geometry of the workpieces is clearly defined: these are sheets with specific dimensions that are wound onto coils at the end.
In steel production, hot milling and casting uses water at rates of between 100m3/h and 10000m3h depending on the scale of the operation. As steel leaves the casting operations, cooling and cutting with water produces mill scale (iron oxides). Mill scale particles range from a few microns up to the size of a fist. They are heavy and …
laden with mill scale and lubricating oil, is drained into scale pits.Large and medium sized mill scales are separated and sent to the sintering plant for recycle to the blast furnace.

Mill scale is a severe nuisance in steel processing. Any coating applied on top of the scale goes to waste. This happens because the steel can be laden with moisture when air gets into it. Electrochemically, mill scale is cathodic compared to steel, so any kind of breakage in the scale could lead to accelerated corrosion in the steel at the ...
