Mill scale (also called scale) is the flaky surface that forms on hot-rolled steel. Its composition includes FeO (iron (II) oxide), Fe2O3 (iron (III) oxide), and Fe3O4 (iron (II,III) oxide). You will find mill scaling on steel sheets, plates, and profiles. It arises when you roll hot steel billets or iron in rolling mills.

Skin pass rolling experiments were performed on a laboratory rolling mill in a two-high configuration, with roll diameter of 136.5 mm and width 200 mm. The surface roughness of the rolls was Ra = 0.16 mm and Rz = 1.42 mm. The rolling speed was adjusted at two different levels: 1500 mm/min and 4600 mm/min.

mills) or exit target elongation (for skin pass mills) The actual roll data such as roll diam-eter, crown, taper, length and texture are also important for a precise calcu-lation. General parameters such as mill and drive limits, standard practices, adap-tion coefficients, yield stress and fric-tion values are stored locally on the
While equipment failure is the greatest indicator of roll slip, increased pellet mill energy consumption (SEC) is also indicative of the roll's struggle to compensate for conditioned mash accumulation at the feed pad. ... Based on previous research conducted using this pellet mill, increasing conditioning temperature from 74 to 85 °C ...
