The Hot Rolling Process - California Steel

Shortly after descaling, a (relatively) small 2-hi rolling mill called a scalebreaker reduces the slab's thickness by about one inch to break up any scale that remains. Just before the next reduction pass is taken, 'sweep sprays' clean away any loosened scale that remains on the slab surfaces. The transfer bar will be descaled

Mechanical Processes for Descaling of Steel – IspatGuru

The colour of primary mill scale is generally bluish black while that of the secondary scale is blue. The secondary scale gives the steel an appearance which is similar to that of a lacquer coating finish and is often mistaken for a blue coloured primer. The primary scale is composed of three well defined layers of iron oxides.
