1. Introduction During hot strip processing, tertiary scale forms on the steel surface after descaling or between each mill stand, at temperatures below 1000 C. The frictional phenomena and thermal conductivity at the interface between the roll and the steel will
Typically rolling mill reheat cycles offer plenty of time to develop a subscale in a prior existing defect. However, for defects that are created during rolling, the limited time at temperature and the decreasing temperatures on cooling make formation of subscales unlikely.
2018/3/1Mill scale was successfully captured from flume water with a strong magnet. • The flume mill scale contains 6 to 30 time less oil than the pit mill scale. • Oil concentrations in the flume mill scale samples are all less than 0.5%. • Cleaner flume mill scale is not due

Along with the production of hot-rolled steel, a large amount of mixture of mill scale, water, and oil is constantly generated. It is of great importance to thoroughly separate these components from one another to make them recyclable. In the current research work, an industrial trial was carried out at an ArcelorMittal hot-rolling mill for producing clean mill scale with negligible oil by
The Rolling Mill at Shelton Steel Works, Etruria, Stoke-on-Trent The photographs taken prior to the closure of the ingot rolling mills in 1964. A 18 million scheme was introduced consisting of a Kaldo steel converter and a continuous casting complex and new section rolling

This rolling mill and the rest of your mill complex, in my humble opinion, truly capture heavy industry in scale. The detail, down to the reflection of hot steel ingots by the rollers in the rolling mill, make me see this as not only a nice piece of scale railroading, but a tribute to the strength of the steel

The oxide-scale structure developed on commercial hot-rolled steel strip at the mid-coil position was examined. The initial oxide scale after rolling and cooling on the run-out table had a three-layer (hematite, magnetite, and wustite) structure; the thickness was found to be a function of the finishing temperature. From this initial structure, various final scale structures developed after
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 2O 3), and iron(II,III) oxide (Fe 3O 4, magnetite). Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling
