The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

2016-12-11Mill scale Mill scale is a heavy oxide layer formed during hot fabrication or heat treatment of metals and is a bluish color. Mill scale will eventually break loose from the steel substrate, taking the coating with it. Steel is anodic to mill scale steel has a lower electrical-chemical potential difference than mill

Figure 410. Schematic illustration of the Steckel rolling mill at Outokumpu Avesta Works. Hot strip rolling In the hot rolling mill, the slabs with a thickness of 140300 mm, each weighing up to 30 tons, are reheated in walking beam furnaces to a temperature often above 1200 C and then discharged to the rolling mill train, Figure 48.

2018-3-17A typical stainless steel foil comes with sharp rolling marks and micrometer-size inclusions, which may cause devices to fail. The most carefully rolled steel has a surface roughness of 100 nm, in contrast to display glass with less than 1 nm. To ensure the electrical integrity of the thin-lm devices made on them, steel foil sub-

MoS2 is applied to medium to high carbon and stainless steels after surface voids have been produced in the material, as by a final annealing operation, but before a final cold working operation reduces the material to finished size. The latter operation embeds or includes the MoS2 into the material and thereby provides a superior lubricated steel for piston ring, shaft, valve stem, spring ...

2011-3-221 Seikei University, Tokyo, Japan 2 Kobe Steel Ltd., Kobe, Japan. ABSTRACT As a new sound absorption material, micro-perforated aluminum thin plate has been developed, which is strong for water, oil, or heat. But thin plate is easily vibrated by sound pressure. And the vibration affects the performance of sound absorption.
